PLANET Indaver considers it its societal duty to contribute to the livability of the Earth through waste management and processing. We strive to operate safely, socially responsible, and sustainably, with minimal impact on our surroundings. From our waste streams, we create value in the form of secondary raw materials, and we promote the sustainable closure of material loops. Our waste-to-energy plants are stable suppliers of alternative energy.

We either destroy or isolate and safely store the hazardous components that should not reenter the circular economy.

Together, we are working towards a clean future.

Value creation from waste streams Indaver Chain Partner

E

very day, Indaver sustainably manages and treats the waste streams entrusted to us. We do this from the perspective that waste has value for society. For Indaver, waste is not an end-product but a source of new raw materials and/or energy. Indaver closes the chain and thus fulfils an essential role in the transition to the circular economy.

treatment of waste streams (among other things) that either are not or are no longer recyclable.

We continually focus on efficient and affordable solutions to generate even more value from waste. In collaboration with various partners, we invest in research into and the development of innovative technologies. These lead to a wider range of high-quality secondary raw materials.

Gatekeeper

Enabler Within waste management, Indaver takes on the role of ‘enabler’. We are a supplier of raw materials and energy from waste streams. Using reliable, energy-efficient technologies, we recover a broad range of basic raw materials from waste streams. These secondary raw materials are always safe, reliable and of high quality. We also generate energy through the thermal

Within waste management, Indaver also takes on the role of ‘gatekeeper’. We protect the materials and food chains against contamination from hazardous or other undesirable fractions. Waste streams that contain such components cannot not be reused or recycled.

Indaver guarantees its customers a safe solution for these waste streams.

Depending on the waste type, we destroy these fractions at high temperatures or neutralise the hazardous components. We store the residual fractions safely in our landfill sites (‘safe sink’). In addition, some waste streams also contain components

such as methane and CFCs (chlorofluorocarbons), which have an adverse impact on climate change. With our Safe Sink Guarantee we not only keep the chains pure, we also destroy molecules that are responsible for global warming.

Guide The four pillars of the Green Deal, which was presented by the European Commission in 2019, serve as our guide. n Reduction of CO2 emissions. n Circular economy. n A clean environment, safe for health and ecosystems. n Clean and affordable energy. (see also p. 11) We contribute to a reduction in CO2 emissions by, for example, supplying green energy to steam networks. We also promote and support the circular economy by recovering materials from waste. We destroy hazardous waste streams and thus protect the environment. We do all this with the utmost care to limit our influence on the environment.

SAFE SINK

Waste products in the green chain are relatively pure and therefore have a high circular potential.

We recover as many materials and as much energy as possible from this.

Waste products in the grey chain contain hazardous substances, also known as contaminants, and have a low circular potential.

With specialist facilities we guarantee a ‘safe sink’: we destroy and/or neutralise all hazardous substances or store them safely in a landfill, thus keeping the materials chain safe.

European policy determines the route The Green Deal

In 2019, the European Commission presented its Green Deal. This ambitious package of measures forms the basis for all objectives that will lead to a European Union that is climate neutral in 2050.

Using these measures, the EU is reshaping itself into a modern, raw materials-efficient and competitive economy.

Indaver contributes to this transition with the following aims. n That in 2050 there will be no net-emissions of greenhouse gases. n To achieve a stable supply of clean and affordable energy. n To reduce pollution to a level that is not harmful to humans or ecosystems. n To achieve a clean and circular economy.

n 2015, the member states of the European Union set out the Climate Agreement in Paris This agreement launched a series of measures to limit global warming to between 1.5°C and a maximum of 2°C. The EU is responsible for implementing the Climate Agreement and since 2015 has issued legislation and regulations on the climate and energy policy.

The EU guidelines form the basis for the member states’ national legislation and regulations.

The European Union wants to be climate neutral in 2050. The use of fossil fuels in member states must be reduced by producing more renewable energy, finding alternatives in production processes and consuming energy more economically.

RED

In terms of energy provision, the European Commission has set itself the goal of making energy cleaner, more reliable and cheaper. In addition, it has constantly refined its goals over the last few years.

These goals are (also see the overview): n the expansion of renewable energy – the Renewable Energy Directive (RED); n the reduction of energy consumption – Energy Efficiency Directive (EED); n the reduction of greenhouse gas emissions.

The Fit for 55-package refines the goals in the field of energy efficiency (EED).

Up to 2022, the target percentage for 2030 was set at 32.5% for both primary and final energy consumption. In the current goals, this is set at 42.5% for the reduction of the primary energy consumption and at 40% for the final energy consumption.

The Directive to promote the use of renewable energy (RED) has also been refined to (among other things) increase the share of renewable energy in the energy mix to 45%.

The European Parliament has approved these revised objectives, and its definitive decision will be made in the foreseeable future.

Fit for 55-package

n primary energy consumption: a

The Fit for 55-package introduced in 2021 comprises measures for the energy sector, among others, to achieve the goal of a 55% reduction in greenhouse gas emissions (in comparison to 1990). In addition, the Energy Efficiency Directive (EED) has not only been refined but also split into:

country’s total energy requirement, including the losses during distribution and the consumption for non-energy purposes; n final energy consumption: the total final consumption by end-users, such as households, industry and agriculture, but not including the consumption by power plants and refineries.

2021 Climate Law In 2021, the European Climate Law was established. It incorporates the Green Deal’s ambitions for 2030 and 2050.

The European climate law embeds the European climate objectives for the next 30 years in legislation.

National Energy and Climate plan At a national level, each member state has drawn up an integral energy and climate plan. This plan outlines their national climate and energy policy for the next ten years. The plan also includes national measures to achieve the required reduction in CO2 emissions.

European policy determines the route Legislative Framework Materials

T

he Waste Framework Directive forms the basis of European legislation on waste products. It sets the frameworks for the national materials and waste policy. The guideline is now c. 45 years old and in recent decades has been expanded and supplemented with regulations for specific waste streams, materials management and safety.

The aim of the European materials and waste policy is: n to reform the European Waste Policy into a sustainable materials policy; n to encourage innovation in the field of ecodesign and recycling; n to reduce the amount of waste that goes into landfill.

The recovery of raw materials is a particular priority.

Circular Economy Package The European Circular Economy Package of 2018 includes significant enhancements to various directives, including the Waste Framework Directive, the Landfill Directive, and the Packaging Directive. These enhancements aim to promote sustainable waste management with increased reuse and utilization of waste streams.

Waste Framework Directive The Waste Framework Directive was last revised in 2018. In 2022, a revision process was initiated with a call for evidence in 2023. The European

Commission has indicated that the revision will focus on preventing food waste and addressing textiles.

It also involves evaluating the performance of member states in terms of recycling rates and source separation. > Waste Framework Directive (europa.eu)

Packaging Directive The European Union established the Packaging Directive (Directive 94/62/ EC) to harmonize national measures for processing packaging waste. Member states are required to take measures to prevent the generation of packaging waste and minimize the environmental

impact of packaging. This directive specifically targets packaging waste, such as plastic, cardboard, wood, and metal. In 2018, the directive was revised, with a particular emphasis on transitioning to a circular economy. By the end of December 2025, at least 65% by weight of all packaging waste must be recycled, and this target increases to 70% by 2030.

Specific recycling targets for different types of packaging and materials have also been established for 2025 and 2030.

The methods for calculating recycling rates have become more stringent.

In late November 2022, the European Commission presented a preliminary proposal for the Packaging and Packaging Waste Regulation (PPWR).

The directive will become a regulation, and the enhanced regulations aim to reduce packaging waste (with a proposed target of 15% less packaging waste per capita in 2040 compared to 2018), promote reuse, increase recycling, and encourage the use of recycled materials.

The goal is to ensure that all packaging is recyclable by 2030. > Packaging waste (europa.eu)

Ireland and Germany have aligned with the European targets, while Belgium and the Netherlands have set higher recycling targets for each waste fraction, exceeding the European requirements, and the targets took effect in 2021.

For example, by 2030, Belgium aims to recycle 70% of household plastic packaging and 65% of commercial plastic packaging, while the EU sets a target of 55% for all plastic packaging by 2030.

Single-Use Plastics Directive In 2019, the EU published the Single-Use Plastics Directive (SUP Directive 2019/904) to reduce plastic pollution.

This directive targets the reduction of single-use plastics and promotes environmentally friendly alternatives.

For instance, PET drink bottles must contain a minimum of 25% recycled plastic by 2025 and at least 30% by 2030. Member states have implemented the directive as legislation in 2021. > Single-use plastics (europa.eu)

Industrial Emissions Directive The European Council wants to regulate pollution from industrial activities. The Industrial Emissions Directive (IED) was drafted for this purpose. This Directive is specifically intended for intensive livestock farming, the production of metal, foodstuffs and chemicals, and for power plants. These industrial facilities are jointly responsible for 40% of the greenhouse gas emissions in the European Union.

In 2022, the European Commission made a proposal to revise the IED in order to implement further measures and to bring it more in line with the Green Deal, with the ultimate goal of having a climate-neutral European economy in 2050.

More Effective Permits The proposal will primarily affect the granting of permits to industrial facilities, so that permits will only be issued to facilities that work with the best available techniques (BAT).

The BAT must ensure that production processes are run as efficiently as possible and thereby limit the

consequences for the environment and health. The BAT for a facility are described in the BREF document.

The BREF documents for waste treatment techniques and for waste incineration are relevant for Indaver.

Our own broad range of specialist treatment facilities and the selected treatment options with third parties across Europe ensure all types of industrial waste are handled and treated correctly. Through the maximum recovery of energy and the high-value recovery of valuable components from industrial waste, Indaver creates a circular economy in practice.

Stable partner As a waste management and treatment company, Indaver is an essential service provider. Industries demand continuity in the management of their waste streams and a guaranteed reduction of environmental impact. Our industrial customers want to have absolute certainty that their hazardous waste will be treated safely and with minimal impact on the environment. Ongoing collaboration with our customers allows us to find sustainable solutions. Even when our customers experience an emergency event, we prove our added value. We are available immediately and do everything possible to handle the situation safely, with minimal environmental impact and in a costeffective manner.

We are steadily increasing our treatment capacity and expanding our commercial activities in Europe. We do this by investing in new facilities and through acquisitions. By offering a broad portfolio of treatment and recycling techniques, which comprise a considerable capacity in the European market, we reinforce the continuity of our service provision.

Industrial Waste Services Knowledge Partner in Industrial Waste Solutions

Fitting Solutions Waste streams are becoming increasingly complex in their composition. We invest in new technology and innovations to allow us to respond adequately to changes and to treat these waste streams as optimally as possible. In doing so, health, safety and the environment are our top priorities.

Because we manage and treat hazardous

or complex waste streams, it is important that we know the exact composition of all waste streams. The more knowledge we have, the safer, the better and the more sustainable will be the treatment we offer. The Waste Identity Card, our identity card for every waste stream, is therefore an essential document in our waste management (also see p. 46). In addition, our data management systems track and monitor the waste streams in real time. The recently developed IndaScan, which records the path of the waste stream from source to the final treatment, is an excellent example of this (also see p. 121).

Increase Indaver values sustainable relations. The contracts for our Industrial Waste Services have a run time

of three to five years. These longer-term contracts guarantee our customers continuity in the management and treatment of their waste streams.

Assessing Customer Satisfaction Indaver values constructive feedback on its service provision. That is why we have regular one-to-one conversations with our IWS customers. We discuss the aspects of our Total Waste Management collaboration and the operational, tactical and strategic key performance indicators (KPIs). These conversations give us insight into customers’ experiences and satisfaction.

Balanced Score Card With the Balanced Score Card (BSC), we conduct an annual review of how our customers assess our performance.

The BSC links the main KPIs per industry sector to our waste management services. Once the score has been determined, both Indaver and the customer receive tailored feedback so that we can devise and implement improvement measures.

RALF OLBORT, SHIFT MANAGER, STAHL CHEMICALS GERMANY GMBH

“Thanks to regular contact and short response times, we are always up-to-date and we can even successfully resolve complex removal tasks together. Furthermore, thanks to the professional advice, we were able to optimise and thus save costs.”

Municipal Waste Services Our ser vice provision to public customers and private collectors

T

he transition to a sustainable circular economy must involve citizens, businesses and governments. Indaver’s package of services supports our public customers and private collectors to work towards this transition. After all, closing the materials loop is at the heart of our mission. In addition, our sustainable energy production makes a substantial contribution to local climate policy.

Private collectors, semi-public or public customers and management organisations are important parties with regard to achieving the goals for sustainable waste and materials management. The European Commission is constantly refining these goals further.

Local authorities in particular have a key role to play because they are responsible for the waste and environment management within their region. Local and national government determines how household waste and, for example,

the sludge from water purification plants are managed and treated. Our scope of operation is therefore very broad and diverse and we continually adapt our service provision to it.

This value creation in the form of locally produced materials and energy means Indaver is helping to strengthen the market position and competitiveness of its customers.

Value creation and collaboration

Guaranteed Service Provision

Value creation from waste streams and extensive cross-sector collaboration are essential to achieve the ambitious goals for 2030 and 2050. Indaver works closely with a very wide range of actors as a waste treatment company, as a raw materials and energy supplier, and as a partner in raw materials chains.

Our state-of-the-art facilities ensure advanced recovery of materials, which we can then supply as secondary raw materials. The thermal treatment of residual waste from households, similar commercial waste and sludge streams produces energy. We provide this stable supply of energy to customers in the form of steam and electricity. We recover granulates from the ash treatment. We convert the green and VFG waste into compost and biomass and, in the Netherlands, into green gas and liquid CO2.

For all of our customers, whether semi-public or public, management organisations or private collectors, the security of the supply from our treatment is of equal importance to a sustainable approach to waste streams.

We guarantee our service provision and ensure it is safeguarded, so that our customers can remain operational at all times.

Our staff have knowledge of the latest developments and our facilities perform at the highest level. We are constantly integrating technological innovations into our service provision to meet or exceed all standards and norms.

Thanks to this closely monitored management and high availability, Indaver can offer a guarantee that the waste streams are always processed under the optimal conditions.

Indaver also provides this same

guaranteed service provision when we run facilities on behalf of our public customers. Our 35 years of experience and expertise in the management of high-technological treatment infrastructure greatly benefits our public customers.

Investing and Running Indaver researches and evaluates new technological insights in the field of waste management and treatment. If the result is positive, we integrate the new development into our facilities or we invest in new infrastructure. In southeast England, for example, we are building the Rivenhall Integrated Waste Management Facility. This innovative, extremely efficient turbine will provide a substantially higher energy yield from the same amount of waste (also see p. 76). In north-east Scotland, local authorities are building an ‘energy from waste’ facility.

Once Indaver takes over operation of this new facility, we will be responsible for running it for the next 20 years and thus for the supply of affordable, clean and locally generated energy (also see p. 71).

Maintaining a Dialogue Indaver wants to maintain a dialogue with our stakeholders so that we can provide an appropriate response to new and changing expectations as a partner.

We also want to support them in achieving their policy goals in the field of sustainability. At the same time, we are working on innovative solutions to support our public and private partners in achieving their goals.

Belgium Continued Investment In the PMD sorting center in Willebroek (Belgium), Indaver has the latest sorting installation. Here, we sort 15 different materials, including various plastics, metals, and beverage cartons, from the packaging waste of 3 million Belgians.

Construction has also begun on-site for the pre-treatment of end-of-life plastic streams such as polyolefins and polystyrene, aiming for sustainable chemical recycling in the new Plastics2Chemicals facility.

The Netherlands Collaborating for improved separation of organic waste (VFG) Collaborative efforts towards better waste separation and processing are crucial in the management and treatment of waste in the Netherlands.

The VANG (From Waste to Resource) program emphasizes close collaboration to enhance household waste separation and improve the quality of different waste streams. This is essential for obtaining high-quality raw materials.

This also applies specifically to organic waste (vegetable, fruit, and garden

waste or VFG). Producing high-quality compost from as pure as possible VFG and green waste plays a significant role in the transition to circular agriculture.

Indaver in the Netherlands takes initiatives in this regard, such as conducting gate inspections and monitoring loads. This allows them to gain better insight into the quality of the delivered VFG and green waste. The results of these inspections and monitoring are communicated to customers, enabling them to focus on improved waste separation along the designated collection route.

Audits improve the quality of our processes

T

o guarantee safety, reliability, performance capacity and traceability, we conduct regular audits or have them conducted by other parties. These audits indicate that our technical and administrative processes comply with the legal stipulations.

We are transparent and improve our processes where possible. Our management systems and several of our end-products are certified.

Internal audits Our internal audits help us to improve our business processes. n Process audits are used to investigate our own processes, to identify and quantify risks and to test the management systems for efficiency and effectiveness. n Compliance audits are used to check compliance with legal stipulations and our permits.

External audits Every year, Indaver is inspected by a number of third parties. n Government inspections in all regions by the government authorities that award permits and check they are being adhered to. n Audits by customers or external certification bureaus who assess our processes on behalf of customers. n Audits by certification bureaus for maintaining or gaining certificates for Indaver’s management systems or for the quality of our end-products.

Independent and recognised certification bureaus confirm formally that Indaver is working correctly and

adhering to internationally recognised standards. n SEVESO inspections Indaver’s sites in Hamburg, Biebesheim, Frankfurt, Stuttgart, Antwerp, Terneuzen, Dublin Port and Dunkirk store and treat hazardous waste. This means they are subject to the SEVESO directive. This European directive is there to manage the risks associated with the storage and treatment of hazardous substances. The directive aims to prevent serious accidents and, if accidents do occur, to minimise their impact on people and the environment.

Audits of third parties Indaver has a large network of reliable partners who, in addition to their own activities, offer specialised logistics and treatment solutions. Careful selection is done through our own Waste Flow and the logistics teams based on geography, flexibility, quality standards, services and price.

Centres that treat waste that is critical in nature, composition or process are

subjected to approval processes.

In addition, we screen the permits, treatment techniques and management systems. For less critical treatments we use existing Qualification Guarantees (QG).

WELL-BEING, CONNECTION AND SAFET Y We live in a fast-changing, complex time full of challenges that require innovative solutions. As an organisation we use our talents to find creative responses to these issues. We invest in our personal and professional development to ensure we remain flexible and agile when faced with any type of change. By putting our physical and mental health first, we can perform at our best in the workplace.

The COVID-19 pandemic highlighted the importance of well-being and connection, especially in the workplace, and we have therefore made these aspects into a key focal point.

At all times and in all areas of our work safety comes first, so that everyone can get home safely after a day at work.

OUR APPROACH

The job market

Uniting and Connecting

There is still a lot of pressure on the job market. Attracting and, above all, retaining staff is a challenge in almost every sector, and for almost every role and level of education. This applies to almost every country in which Indaver is active.

Indaver demonstrates that our staff’s efforts matter and that we are committed to a sustainable relationship with all of our people. Retention of good staff is extremely important. Every staff member who leaves to join another employer takes some knowledge and experience with them that his or her replacement must then acquire. We attach great value to and strive for good mutual connections between the organisation and our staff, and among staff members. Our core value of ’Ensuring a clean future together’ is a clear reflection of what unites and fascinates us in our daily work.

The previously predicted exodus of retirement-age staff has now commenced.

Transferring their expertise and experience will require time and careful consideration.

Continuing to Work Happily and with Vitality The retirement age continues to increase steadily in several countries. Based on this fact, it is important that staff can still perform their role with vitality for those additional years. Employers and employees have a joint responsibility to help everyone to feel motivated and happy in their work. This sustainable employment begins with young employees and is different for everyone.

Indaver’s distinctive qualities as an employer are important in today’s narrow job market. In addition to replacing our retirement-age staff, we also need to take on new people thanks to the growth in our activities. We want to unite and connect with these new colleagues, too.

Healthy and Energetic

Finding and connecting people

A

longside an aging population, Indaver is also facing an exodus of staff who have reached retirement age. We want to retain their knowledge as well as possible within the organisation.

Mutual knowledge transfer between colleagues is important, as is attracting new staff who can take over these vacancies promptly. In addition, we are looking for new staff to support our growth.

Employer Branding Social Role Attracts New Colleagues To attract new staff, good brand awareness is important as is a wide awareness of our social relevance. Young people, in particular, often deliberately choose an employer that adds social value and that actively strives for a better society.

Indaver’s social value is evident. As a waste management and treatment company, we fulfil an essential role in the transition to the circular economy.

We actively publicise our vision for the circular economy and our role in closing

loops. Our core value of ‘Ensuring a clean future together’ expresses precisely what we stand for. Through our core values and employer branding we can position ourselves on the job market recognisably and in a targeted manner. This allows us to maintain control of our recruitment. Where necessary, we work with selected partners that know Indaver well.

Naturally, we attend job fairs where we highlight our relevance for society.

The use of social media In addition, we consistently position ourselves as a relevant international player in the field of sustainable waste management on our social media channels. On the one hand, to recruit new colleagues and, on the other, to strengthen the bond with our current staff. Our vacancies and the Indaver employer brand story are given a prominent position on LinkedIn. The result of all these recruitment efforts is that applicants fit our company philosophy better for a targeted match.

This means that we are able to fulfil our vacancies sustainably.

Our own ambassadors There are no better ambassadors than ourselves. If we enjoy what we do, are satisfied with our role and activities and the training opportunities and career prospects we have, then we are more likely to suggest relevant vacancies to friends, family and acquaintances.

Not only is the organisation happy with the colleagues who join us via this route, it also feels good that so many employees are proud of Indaver. We

WASTE HEROES WEEK In the Netherlands, the public perception of people who work in the waste sector is not very good.

This became apparent from a survey conducted in 2022 on behalf of the NVRD (the Royal Dutch association for waste management and cleaning) and the Association of Waste Companies.

During the annual Waste Heroes Week in March, the sector highlights how varied the work can be and what technical and non-technical knowledge is required. This extra focus is also intended as recognition for the 30,000 Dutch men and women who collect waste from households and businesses every day. Indaver in the Netherlands takes part in Waste Heroes Week at every site to celebrate its staff.

Finding and connecting people

Without inclusiveness, diversity will never be able to flourish. Indaver does everything possible to increase the diversity within our organisation, to offer work opportunities to everyone, and to connect everyone within the organisation.

RAMON FATEHMAHOMED, MACHINIST/GENERAL STAFF

“I feel great here. I have nice colleagues and the work is varied. In the North and MidZeeland landfill site I use the compactor and the GPS system to keep everything in order. I work on the weighbridge, sometimes on the loader and I carry out checks. It’s very varied, which I really like.”

Diversity and Inclusion Diversity among colleagues – including differences in level of education, gender, cultural background, skill, level of capacity for work, etc. – strengthens the organisation.

Inclusiveness – the inclusion of these differences, mutual solidarity, demonstrating concern for each other and unity – makes the organisation stronger, too.

people who are long-term unemployed.

Social return on investment (SROI) increasingly makes up part of the tender process. Indaver in the Netherlands offers several work placements to people who need extra support to get back to work.

Bringing cultures together

OUTLOOK

You could say that the Indaver Willebroek site (in Belgium) is a melting pot of different cultures. For example, many of our staff speak another language than Dutch or French This requires additional effort to ensure everyone can work together safely and efficiently. We ensure that our supervisors are able to translate as necessary. In addition, our training is geared to the fact that shift leaders are not always proficient in Dutch or English, to ensure they can still gain new knowledge and are able to continue to develop in a new role.

In 2023, Indaver will present its policy document on inclusivity, diversity and its ethical principles regarding working conditions.

s an international organisation, mutual connection among all staff members is extremely important to Indaver. If you know each other, and know who does what, you can find each other more easily when you need to. Mutual connection contributes to the sense of solidarity that strengthens the organisation as a whole. People who feel connected are less likely to look for a new employer. In this narrow job market that is more important than ever.

VriendenKring and VriendenClub (Friends Circle and Friends Club) KIRSTEN BLOMMAERT, SITE PLANNER

“As a newcomer to the Antwerp site, it was enjoyable to meet people from other departments during the team-building activity. Not one person in particular. Now, when I walk around onsite, it’s nice to be able to put some names to faces.

One of the ways to maintain contact between colleagues is staff societies.

At Indaver in Belgium there is the Vriendenkring and in the Netherlands it is called the Vriendenclub. Both organisations are very active and organise fun and varied activities for their colleagues every year: from water-skiing to an African cooking workshop and from a large party to celebrate Indaver’s 35th anniversary (in Belgium) to the traditional family day and a ‘dropping’ (a team orienteering game in which participants are dropped off in an unfamiliar location).

Employer clubs Colleagues from Indaver in Ireland are able to take part in a range of activities.

Meath has a running group that comes together to run at least once a week.

There is also a cultural club active on this site that organises several activities to increase mutual connection.

Belgium Team-building in Antwerp On the Antwerp site, everyone works in their own department. Together, all of the colleagues form a chain that ensures everything runs smoothly from start to finish. To get to know each other better, all 140 staff (approximately) from the site were invited to a team-building event. In five groups, which included a mix of people from all departments, staff were offered a varied programme of activities. Teamwork was key in all of these very successful sessions.

MANU BERTELS, TECHNICAL MANAGEMENT TRAINEE

“It was nice to see everyone outside the working environment. You get to know the people who participated in a more personal way. Activities such as catapult building, where you have to work together, the creative and sporting factor of team building contributed well to this.”

Connected to each other An Inspiring Sustainable Tuesday at Indaver: A Day of Connection and Sustainability

A

t Indaver, it’s not just about waste management and sustainability; the well-being and engagement of our employees are equally important.

That’s why in 2022, we organized another Sustainable Day, this time on a Tuesday, a day where information, awareness, connection, and enjoyment came together. And it was a great success!

The Sustainable Tuesday offered an impressive program. Our employees were immersed in a sustainable atmosphere, where they could participate in various workshops and lectures on diverse topics. Sustainable entrepreneurship, sustainable mobility, sustainable employability, recycling, circular economy, and sustainability in the workplace took center stage.

What made this day even more special was the inspiring and creative setting of the Verbeke Foundation (Stekene, Belgium).

Colleagues presented posters about their own sustainable projects amidst the greenery and trees. The workshops and lectures took place in unique locations such as the glasshouse, collage museum, under an airplane, or amidst artworks and installations. For those

who wanted a more active experience, there was a guided walk on the estate or the opportunity to participate in the Trash Design workshop.

The excellent evaluation of Sustainable Tuesday speaks volumes: a score of nearly 9 out of 10 for organization, 9.5 out of 10 for communication, 8.4 out of 10 for personal satisfaction, and 8 out of 10 for the program.

One of our employees mentioned, “Kudos for the careful preparation, smooth execution, and attention given to a diverse offering with sufficient space for informal contact. I hope this event becomes a recurring one.”

50-50-50 philosophy

“Thanks to the 50-50-50 philosophy, I can do my work more efficiently. Where I used to have two hours of travel time for a half-hour meeting, now I just schedule a call.”

We currently work at home for 50% of the time in roles where that’s possible, which means we travel 50% less and have 50% fewer face-to-face meetings.

Digital meetings have replaced a portion of our traditional meetings, thanks to optimal IT support.

Therefore, we ensure that we still have regular opportunities to see and speak to each other personally. By reducing our travel, we also spend less time on the road and contribute to reducing CO2 emissions.

The choice to have 50% physical meetings was made intentionally because in-person encounters are important for informal contact and engagement.

JESSE VERLINDEN, PROJECT ENGINEER

I find the way of working that comes with the 50-5050 philosophy very positive, although the contact with colleagues is different from when you see each other physically. We are looking as a department to be at the office together more often.”

t is important to Indaver that its employees are happy, healthy and fit at work. Since the retirement age is still steadily increasing in several countries, a balanced, flexible and sustainable career is important in order to reach retirement in good health.

Indaver in Germany, Ireland and the UK to fit the issues the staff have in those locations. The wide range of support available means it can address several issues: from improving physical and mental well-being’, to bullying in the workplace or a crisis situation at home.

The options even include (limited) legal or financial advice.

The EAP provides this support online, over the phone or in person, as desired.

This is always on a confidential basis and Indaver, as the employer, has no access to the questions asked or the support received. In 2022, the EAP was used regularly.

Indaver has several programmes to support its staff in a healthy and energetic career. For example, colleagues in Germany, Ireland and the UK can use our Employee Assistance Program (EAP). This programme provides direct support 24/7 in the fields of health, work-related and personal matters. The implementation of the EAP is tailored to the needs of

For several years now, colleagues in Belgium and the Netherlands have been able to follow the IndaFIT sustainability programme. In addition to an online questionnaire about work-life balance and mental and physical health, this programme also offers a consultation with an external, independent coach who provides support to take steps towards personal improvement.

NEW OCCUPATIONAL HEALTH AND SAFETY SERVICE (ARBODIENST) Indaver in the Netherlands and Richting health and safety authority began working together on 1 January 2022. This led to a new approach to the sick-leave process on all sites, except for in the north. The company doctor still has ultimate responsibility, but a case manager deals with the initial contact and notifications. The case manager focuses mainly on what staff are still able to do while they are on sick leave. Using this approach, the length of short-term sick leave has reduced by 2%, which shows that this proactive approach works. In the event of longer-term sick leave, the case manager coordinates the obligatory steps to be taken in line with the Dutch Eligibility for Permanent Incapacity Benefit (Restrictions) Act “Wet verbetering poortwachter”.

Preventative Medical Medical check-up Indaver offers its staff in Belgium and the

Netherlands the opportunity to take part in a preventative medical exam.

The results of this free health check, which takes place during work time, and the advice given are confidential. Indaver only receives a general group report at the end. We use these reports to improve the sustainable deployment programme and, where necessary, to tackle working conditions in the workplace.

STOP-SMOKING PROGRAMME In 2022, our staff in Belgium and the Netherlands were offered a stop-smoking programme. We used various methods (cost, fitness, vitality, the effects of quitting) to encourage the smokers and vapers among us to take part.

The programme consists of eight meetings of 90 minutes each, over a three-month period.

Sports Clothes for Runners and Cyclists

Tandje Bij (Electric) Cycling Refresher Course

Exercise is good for your physical and mental health. Since 2021, Indaver staff have been able to exercise in a stylish work outfit. The range includes shirts, shorts, trousers and waterproof jackets for both runners and cyclists. The prices are around 50% lower than the cost price. This low price is a reward for the sports effort being made by our staff. At the same time, the Indaver sports outfit is a beautiful, understated way to increase our brand awareness.

The success of the lease bike scheme at Indaver in Belgium has been huge.

E-bikes, in particular, are very popular.

At the same time, we know that the number of bike accidents is growing, even among our colleagues. For us, safety always comes first. That’s why we are offering a cycling refresher course.

There is a theory section that covers the main rules of the road. The practical session involves simulated traffic situations and there is room to practice on site, with your own bike.

Indaver Lease Bike Cycling is a healthy and environmentally friendly way to get around. Following on from Indaver in Belgium’s sustainable mobility programme Tandje Bij, colleagues in the Netherlands have also been able to lease a bike since 2022.

The choice of bike is free. Furthermore, Indaver contributes to the lease costs.

The Indaver Lease Bike fits in perfectly with healthy, sustainable mobility, whether you use the bike for travelling between work and home or in your free time. The use of the (electric) bike is one of our key points in this area.

WELLNESS HOUR In 2022, staff at Indaver in Ireland and the UK were given the opportunity to take part in a wellness hour. This means they could take part in a healthy or well-being activity for one hour per week, during work time.

In 2022, Indaver in Ireland once again received the prestigious KeepWell Mark.

This award is in recognition of our efforts for our staff’s welfare and wellbeing and their sustainable employment.

We were nominated for this accreditation by two external organisations.

The KeepWell Mark is recognised by the Irish Business and Employers’ Confederation (IBEC). IBEC assesses companies on health, employee benefits, flexible work opportunities, maternity leave, training and development, equal opportunities and knowledge development.

Training, developing and flourishing

I

ndaver believes it is important that staff feel seen and valued, so that they want to further develop at Indaver and build a career with adequate development prospects.

Our employee life cycle gives everyone opportunities for development on both a personal and a professional level.

Knowledge management Stemming from our core value of ‘Continuously improving’, we encourage everyone to continue learning, to keep their knowledge up-to-date and to give their talents time and space to flourish.

This is part of our knowledge management. We provide structured learning opportunities, for which we always choose the best option. This could be traditional training in the workplace, through e-learning, by video and animations, or through a combination of options (blended learning). The advantages of e-learning

are that everyone works through the exact same learning material and staff can follow the course at their own pace and at a time and place that suits them.

E-learning also offers the flexibility to give fast and efficient training.

Training Offer Via the training platform, staff can see which courses, refresher courses and training are required, relevant or interesting. In 2022, we extended the offer further with practical courses aimed at personal development within the work environment. Indaver also has a platform that gives access to around 100 additional general e-learning courses.

This extensive and accessible course offer ensures all colleagues have the same educational opportunities, both on a professional and a personal level.

Furthermore, it gives them the opportunity to take their career in a new direction, including within Indaver.

WASTE MANAGEMENT TRAINING The waste streams that Indaver manages and treats can be complex in terms of their composition and treatment. To give insight into these materials, Indaver offers all staff the internationally oriented Waste Management training.

In this course, we pay attention to the ethics of waste management, among other things, and cover every aspect of waste management ‘from cradle to grave’. Internal specialists share their expertise on each section of the course. We have two versions, a general version for all members of staff and more specialised training at an expert level. We provide the training in both digital and traditional forms, and we also link the theory to the practice by visiting sites and facilities.

It goes without saying that this training is part of the onboarding process for new staff.

Every year, Indaver offers its supervisors the Triple C training courses. The Triple C leadership method uses the careconnect-coach principle. Supervisors are also given support in their leadership with our 50-50-50 philosophy.

In Ireland, the Triple C training was aimed at senior management in 2022.

In 2022, Indaver in Germany began with a development centre for the staff who do shift-work. Through this platform we can find out who on our staff can and wants to move to a supervisor role at Indaver. For this, the staff have a oneday assessment. If they are successful, we offer them training. The initial reaction to this offer exceeded expectations and there was an enthusiastic response from the participants.

Safety, our priority SOCIAL CONTEX T

OUR APPROACH

Working safely

Work safe, get home safe

A safe workplace concerns everyone. The employee takes responsibility for working safely. The employer ensures all workplaces have the correct and safe equipment, and that there is a good safety culture within the company. The guidelines for this safe workplace come from the government, which establishes the legislation and regulations. So, we all work together to create a safe work environment.

We work safely, or we don’t work at all. That is Indaver’s philosophy.

We have implemented policies, procedures and management systems for that purpose. Our regional safety departments ensure these are implemented and monitored correctly. In addition to that, an open safety culture is vital to ensure that staff feel free to discuss unsafe situations and to make suggestions for improvements. Because everyone wants to get home safe.

Cyber Criminality All too often Cyber criminals now use ransomware, which has serious consequences for conducting business in our digital society. This puts constant pressure on the digital safety of companies and their stakeholders. Everyone is part of the digital chain and everyone needs to accept their own responsibility within that.

Digital Awareness A business is as vulnerable as its weakest link. Often, this weakest link is humans. Now that working from home has become the norm for many staff, based on our 50-50-50 philosophy, digital awareness is more important than ever. We protect our digital safety within the chain and help our staff to stay alert.

Indaver compares its safety figures with the available data from the Belgian waste sector. 2021 is the most recent year and shows a frequency rate of 20.4. In 2022, our rate of frequency was 7.0, which is far below the group target of <10 and very close to the chemical sector’s target of 6.5.

If we are to have a successful safety culture, we have to know where the risks lie, both in terms of location and physically. We have been analysing the causes and effects of injuries since 2022.

02

COMPARING SAFETY FIGURES

Based on these data we can roll out targeted campaigns to increase safety awareness and to take proactive measures.

01

Indaver actively works to reduce the number of accidents involving lost work time or absence. These are incidents that result in a member of staff being unable to come to work for more than one day (rate of frequency).

We keep a record of our safety performances using a central Incident Registration & Management System. To improve performance and reduce the number of incidents, we work hard on preventative reporting of dangerous situations. The number of reports increased again in 2022. We follow up on these reports with points for improvement and measures to prevent the risk of injury.

Cause and effect of injury

02

Incidents Resulting in Lost Work Time or Absence

We can see that this approach works: both the number of people having accidents and the number of days that people cannot work as the result of an accident are reducing steadily. This translates back into the rate of frequency, which reduced significantly in 2022 from 9.3 in 2021 to 7.0 in 2022. These are figures for the entire Indaver Group, including contractors.

E

very year, Indaver initiates a range of projects and campaigns to strengthen the safety culture among its staff and contractors, to promote safe behaviour proactively and to strengthen digital resilience. Our safety figures show that this policy works. At the same time, we know that this work will never be finished.

Strengthening the safety culture is a continual process, and one in which supervisors must set an example.

ADRIE KAIJSER, GROUP SAFETY MANAGER

“Safety is important in every layer of your organisation. You achieve a good safety culture through good leadership.

Safety is a supervisor’s footprint, it is his or her responsibility to take the lead on this.”

Continuing to Increase Training and Professional Knowledge At Indaver, training courses are an important part of our safety policy.

If staff do not know or understand the safety procedures well, undesirable situations can arise. Operational staff, in particular, regularly follow legally required training courses to keep their certification up-to-date. Operational courses and soft skills are also included in the training programme that makes up part of our knowledge management (also see p. 40).

As with other training courses, Indaver offers its safety training in multiple formats: through e-learning, in the workplace and traditional. In 2022, we finalised the e-learning course on HAZOP-LOPA.

Raising Awareness of Cyber crime To keep the digital safety of our business activities robust, we regularly conduct awareness-raising campaigns on cyber-crime. In 2022, we took a baseline measurement. We can then use these results to measure the effect of our campaigns (also see p. 124).

“Since devoting more attention to incident reports around the bunker (dust escaping from the bunker, fires) we have seen far fewer problems.”

Belgium Improvements lead to a proactive safety culture In Antwerp (Belgium), Indaver has had a five-year-long chain safety programme, leading to a proactive safety culture.

This is a far-reaching project within Indaver. The experience we gain in Antwerp can also be applied to other sites. In 2021, this site developed a way to make the laboratory’s reactivity and compatibility tests for the tank park easier to carry out. In 2022, we also rolled out this new approach on the IWS sites in Terneuzen (the Netherlands) and Indachlor (France).

E-learning In 2022, consideration was given to further improving the incident reporting system. We have designed an e-learning session to give staff support on how to fill it in. This shows where a report should go, how to fill it in correctly, and what the difference is between the cause of an incident and the consequence.

We have also improved our follow-up on reports to provide immediate action.

VIDEO

Waste Identity Card Another big improvement process in 2022 was the digitisation of the Waste Identity Card (WIC). This is what is known as the acceptance sheet for the safe and efficient treatment of liquid hazardous waste. On the form, for which the customer provides the most recent information and then signs it, it states, among other things, what the waste consists of and the associated safety data. In 2022, we made the pdf into a digital form. As a result, we can prevent errors caused by manually transferring data and everyone has insight into the data at all times. Five departments were closely involved in this improvement process (also see p. 121).

Belgium World Safety Day At the end of April, during World Safety Day, in Doel (Belgium) the drivers in Indaver and SLECO’s waste acceptance halls were given a talk on the correct use of their Personal Protective Equipment (PPE). This year, the focus was on fall hazards. In both focus areas, Indaver shared the videos of Belgian Waste-to-Energy on social media.

Just as in previous years, the drivers who scored 100% on both points were rewarded with a small gift.

Furthermore, the number of accidents with lost work time decreased considerably.

Ireland and the UK Safety Champions

Germany Warn mich! Danke In 2021, Indaver in Germany launched the safety campaign ‘Warn mich! Danke’ (Warn me! Thank you). The aim of this campaign, which was part of the German safety project, is to prevent accidents caused by unsafe behaviour. Staff need to become used to warning each other when they are in an unsafe situation.

They must also learn to accept a warning as a sign of caring, not as a criticism.

Because the first time you may be the one giving a warning, but the next time you could be receiving it. There is never any excuse for working in an unsafe situation or for unsafe behaviour.

The result of this German safety campaign is that in 2022 there were many more reports of unsafe situations.

Every quarter, Indaver in Ireland and the UK pays extra attention to its staff’s safety reports. The reports are sent through to the management and the safety officer on the site anonymously.

They choose three reports each quarter.

The people behind these reports are the Safety Champions for that quarter. Their report, the follow-up action and an

explanation from the supervisor as to why this is a good example are published on Indanet. This creates 12 Safety Champions each year and multiple improvements on our sites.

and to give other people insight into their conduct. Extra attention is required for contractors and other external people who are present on our sites.

The Netherlands Safety Week

The Netherlands Safe Transfer of Liquids

Every year, in the first week of June, the Dutch waste sector organises a Safety Week. Pointing out unsafe behaviour to each other was the theme for 2022.

Although it can be difficult at times, voicing concerns to each other is important to make the situation safer

In 2022, IWS Terneuzen (the Netherlands) worked on improving the safety of pumping liquid waste streams over to another location. Using radio frequency technology (an RFID code), we can digitally link every arrival to the laboratory system and to the operators’ digital system. The result is that the responsibility for the safe transfer of liquids by pump no longer lies solely with the operator, but is shared broadly.

The Antwerp site has since begun investigating whether this system would also be suitable for use there (also see p.

123).

WORKING TOGETHER ON A CIRCUL AR ECONOMY As of November 2022, eight billion people inhabit the Earth, and that number is still growing. These high population figures put a huge strain on the Earth’s resources. The need for the transition to a sustainable, circular economy (an economy in which we reuse raw materials again and again) has never been so clear.

Governments, the business world, education and social organisations have a joint responsibility to make this transition happen. Together we can generate and share sustainable energy, reuse products, recover raw materials and restore biodiversity.

If we make the switch now, from a linear to a circular economy, it will give our children and grandchildren the chance of a healthy and prosperous life, both now and in the future.

Care for the climate SOCIAL CONTEX T

Further Limiting Greenhouse Gas Emissions The earth is heating up dangerously due to greenhouse gas emissions. The most well-known greenhouse gas is CO2, which is released when fossil raw materials are burned. Industries are still dependent to a great extent on fossil fuels for their production processes and energy generation.

European Climate Policy The focus of the EU’s climate policy, which is based on the Paris Climate Agreement (2015), is the reduction of CO2 emissions. The European Green Deal refined these ambitions in 2019. In 2030, CO2 emissions must be 55% lower than in the reference year, 1990. To this end, the EU drew up a package of measures in 2021, under the name Fit for 55-package (also see p. 13).

In 2050 the member states must be climate neutral.

National Climate Plans All member states have drafted an Integral National Energy and Climate Plan (INECP). Among other things, this includes measures for the various sectors to achieve a reduction in CO2 emissions.

OUR APPROACH

Reducing CO2 Emissions in the Chain

In line with the ambitions of the Green Deal (also see p. 11), Indaver limits CO2 emissions where possible. This means we focus on green energy production and recover as many secondary raw materials from our waste streams as possible. In so doing, we ensure a significant reduction of CO2 emissions at other points along the chain. In addition, we are working to reduce our own CO2 emissions, with the ultimate aim of becoming climate neutral.

We work with our partners to find innovative solutions for the CO2 emissions that do still occur. For example, we investigate whether, once captured, they can have a useful application or be converted into new raw materials.

Energy-Saving Business Operations Indaver constantly monitors the energy consumption of our facilities, processes, buildings and logistics operations. The insights provided by these data, supplemented by energy-saving advice from the external agencies we consult regularly, ensure our processes and facilities operate as economically VEILIGE KRINGLOOP as possible, thus saving energy and limiting our CO Bij de verwerking emissions. van In gevaarlijke our Carbon 2 Management Plan we describe projects that stoffen will ligt be our de focus meansop ofhet achieving veilig the goal to limit our CO2 emissions. houden van de kringloop.

The Indaver Carbon Management Plan

I

ndaver’s Carbon Management Plan shows how we will reduce and prevent CO2 emissions and how we are making a substantial contribution to a climate-neutral Europe. We close loops by recovering materials from waste and we prevent the use of fossil fuels by recovering energy, and these actions reduce the emission of CO2 within our chains. This circular solution is a sustainable way to achieve the European objectives of the Green Deal.

Indaver Carbon Management Plan We believe it is extremely important for our customers to have insight into the efforts we are making to reduce CO2 emissions or to prevent them completely.

The Indaver Carbon Management Plan provides a clear description of our short- and long-term strategies and the goals we have already set.

We have drawn up the Carbon Management Plan in collaboration with a wide group of stakeholders and experts.

It shows our customers precisely how and in what areas we are tackling CO2 emissions, now and in the future. > Indaver Carbon Management Plan

Reduction in Greenhouse Gas Emissions The focus of the policy document is based on the main principles of the European Green Deal. The ultimate goal of the Green Deal is for the EU member states to be climate neutral in 2050.

Before that comes the step of achieving a 55% reduction in greenhouse gas emissions by 2030, which is now a legal obligation (also see p. 12).

The Indaver Carbon Management Plan Preventing CO 2 emissions, recovering raw materials Three Goals We have split the Indaver Carbon Management Plan into three goals.

1. As gatekeeper and enabler, we must destroy as much CO2 as possible and/or ensure that no CO2 is created by keeping carbon within the chain. n As a waste management and treatment company, Indaver destroys a lot of greenhouse gases in its rotary kiln incinerators in Antwerp (Belgium) and in Hamburg and Biebesheim (both in Germany). n We prevent CO2 emissions by keeping carbon in the chain through recycling. We do this biologically through composting, and we do it chemically through our Plastics2Chemicals (P2C) facility (from 2024 onwards) and the solvent recycling facilities in Belgium and the United Kingdom.

We sort the collected PMD waste (plastic packaging, metal packaging and drinks cartons) so it can be recycled via the mechanical or chemical route further along the chain.

2. Using alternatives to reduce preventable CO2 emissions. n We reduce consumption of fossil fuels in our own processes, buildings and vehicle fleet.

We are committed to making our vehicle fleet electric, making our buildings climate neutral and increasing the share of self-generated, renewable sun and wind energy in our own energy supply.

3. We deploy our treatment process, which is associated with unavoidable CO2 emissions, as optimally as possible. n We recover every last feasible joule of energy from the waste streams we treat in our thermal facilities. We do this in our modern waste-to-energy facilities and as a partner in heating and steam networks. n Our efficient facilities recover valuable raw materials from waste streams, such as the precious metals that IndaMP recovers or the granulate from our incinerator bottom ash. By doing this, we save energy further along the chain, which would be necessary for the production or extraction of primary raw materials.

n We investigate the possibilities for applying Carbon Capture and Storage (CCS) and Carbon Capture and Utilisation (CCU). However, we expect that we will only be able to use the best available technology after 2030, when the technology and infrastructure become available.

By focusing on these goals we are contributing to the stated objectives of the Energy Efficiency Directive (EED), the Waste Framework Directive (WFD) and the Renewable Energy Directive (RED). Together they form the legislation as established by the European Commission (also see p. 11-15).

The Indaver Carbon Management Plan takes the planning stipulated by the EU into account. The characteristic features of the waste treatment sector also play a role. It is clear that the sector needs a specific greenhouse gas protocol.

The Indaver Carbon Management Plan Reducing our own Fossil Fuel Consumption

Reducing our own Fossil Fuel Consumption For years, Indaver has been working on green and sustainable transport options for our staff. Indaver in Belgium has been running the mobility scheme TandjeBij since 2019, which helps staff to make sustainable mobility choices.

In 2022, we provided the Doel and Willebroek sites in Belgium and the Nieuwdorp site in the Netherlands with charging points for electric and hybrid cars. Also in the Netherlands, staff have been able to lease electric bikes since 2022, so they can travel to work sustainably.

OUTLOOK We want to further reduce our consumption of fossil fuels via the electrification of our vehicle fleet. It is expected that half of the fleet will be electric or semi-electric by the end of 2023. In the meantime, charging points will be installed at more sites.

The Indaver Carbon Management Plan Preventing the Consumption of Fossil Fuels

Preventing the Consumption of Fossil Fuels Indaver strives to prevent the use of fossil fuels and opts for renewable energy sources. This is why we are focused on self-produced energy sources, such as sun and wind energy.

The Antwerp site (Belgium) is evolving into an energy cluster. We have various projects underway to make this site even more sustainable, which will increase the share of renewable energy.

On the covered area of our landfill site at Hooge Maey, we have the option to combine multiple land use with energy production. In 2022, we carried out the preparatory work for the research into the installation of a 15 MWp solar park as an extension of the existing solar-panel pilot project.

There are already two wind-turbines on this site and we are currently investigating the possibility of installing more turbines (also see p. 78).

We also make use of renewable energy on our sites in Willebroek (Belgium) and Terneuzen (the Netherlands) (also see p. 78).

of waste. New high-voltage cables have also been installed to create a better connection with the Elia high-voltage network.

Using energy efficiently In addition to multiple use of land on the Antwerp site for energy production, this site is also working on a more efficient use of energy. Indaver is investing in a new turbine for the rotary kiln incinerators, which will allow us to get more energy from the same amount

OUTLOOK In 2023 there will be an extensive study into the solar park and the preparations for its implementation will begin. The solar park will be operational in 2025.

Reducing Energy Consumption

n When replacing diggers, cranes and mobile screening

The reduction of fossil energy consumption is closely linked to the reduction of energy consumption. Therefore, Indaver in the Netherlands carefully monitors energy consumption on all of its sites.

plants, we investigate whether it is possible to buy an electric version, taking into account their intensive use.

For now, however, that is not (yet) the case. n We would like to reduce the energy consumption of Bio Power Alphen’s process fans. This could be achieved by adapting the composting process. But to do this, we would need to extend our electricity connection. This can only happen once the regional electricity grid has been adapted, which is planned for 2025.

We draw up an energy balance sheet for each location, and every four years we conduct an energy audit. This systematic energy audit, based on the European Energy Efficiency Directive (EED), gives a detailed overview of each location’s energy streams: from the buildings, the industrial processes and facilities, the transport and heating. We bundle the audit reports together in a quantified overview, called the Energy Management Action plan (EMA). This indicates what measures can feasibly be taken to further reduce energy consumption over the following four years.

Investments In our investments we also look specifically at energy consumption: n The new post-treatment facility for our RotterdamEuropoort VFG composting site has separate kilowatt hour meters per section of the facility. This enables us to monitor our energy consumption even more closely. The facility uses more energy overall than it did previously, to increase the quality and quantity of the compost. The new hall has been fitted with LED lights, which provide better light, more economically.

Capturing, Transporting and Storing or Using CO2

Indaver is continuously working to recover materials and energy to achieve a reduction in CO2 emissions in the chain. Along with various partners, we are also researching the possibilities for storing CO2 safely following capture (CCS) and seeking to find the most useful applications for it afterwards (CCU). For example, we supply liquid CO2 from our Dutch VFG digester Bio Power to the horticultural industry.

They use this product to improve the growth of their plants. The use of liquid CO2 prevents the use of fossil fuels.

Destroying hazardous, toxic substances As gatekeeper, Indaver’s main task is to keep hazardous waste out of the loop.

In our rotary kiln incinerators (RKIs) we destroy many different hazardous, toxic substances, including substances with a high global warmth potential (GWP).

During the thermal destruction of these hazardous components, CO2 is released.

This is inherent to the production process. But in addition, we destroy multiple greenhouse gases. So, the IndaChlor facility in Dunkirk (France) destroys carbon tetrachloride (CCl4), which is much more harmful to the environment than CO2.

hazardous waste in our rotary kiln incinerators also fits in seamlessly with the Green Deal’s objective of a toxic-free environment and a clean and circular economy.

OUR APPROACH

European Green Deal

Recovering Raw Materials

One important goal of the European Green Deal is economic growth without exhausting the Earth’s resources. However, some fossil raw materials are becoming ever scarcer, while demand keeps growing. The mining of these materials is harmful to the environment, and the transport lines involved are often very long. Secondary raw materials, which are recovered from waste streams, have shorter lines and can make up the shortfall.

Value can be created from waste, that’s what Indaver stands for. By making optimum use of waste streams, they become part of the circular economy.

We invest in high-tech facilities and innovative processes to recover valuable and often scarce raw materials. Thanks to Indaver Molecule Management, we are also able to break down complex waste products to a molecular level, after which we supply valuable secondary raw materials back to the industry.

Quality, Reliabilty, Safety

Closing materials loops

Secondary raw materials must not be lower than the primary raw materials in quality, reliability and safety. Industry and society must be able to build on them.

The increase in contaminated waste streams and the increasingly complex components they comprise demand bigger efforts in the sustainable treatment of waste streams.

The market puts high demands on its raw materials. The secondary raw materials that Indaver produces satisfy the same quality demands as the primary, fossil raw materials: they are pure, reliable and safe. This makes them a worthy replacement in the industry’s production processes. With the recovery of raw materials from waste, we are closing materials loops and taking a large step towards the transition to a circular economy.

Legislation and Regulations

VEILIGE KRINGLOOP

The European Parliament provides the frameworks for national and international legislation and regulations. The European Circular Economy Package 2018 (also see p. 14) sets strict goals for sustainable waste management, among other things.

Its focus is on preventing, reducing and recycling waste. In 2022, the European Commission proposed a new package of measures that expands the ecodesign rules in particular. Ecodesign takes the entire life cycle of a product into account, from the extraction of the raw materials to their reuse as secondary raw materials.

CONCRETE PAVERS MADE FROM GRANULATE

Ash treatment Following the incineration of nonrecyclable household and comparable industrial waste, bottom ash is remaining.

The ash treatment facility in Doel (Belgium) processes the bottom ash into useful end-products for the metal or construction industries. The bottom ashes from our fluidised bed incinerators are also valorised. > Web page ash treatment

Indaver and Marlux-Stradus, a producer of concrete pavers among other products, are collaborating on a project to produce concrete pavers using secondary raw materials. Granulate recovered by Indaver from bottom ash is utilized for this purpose. This project is one of the two symbiosis projects selected to promote the circular economy in the Port of Antwerp area. An independent jury of experts assessed the submitted projects based on criteria such as environmental impact, scalability, innovative character, and potential for realizing a tangible investment that supports Flanders’ efforts to reduce household waste or material consumption.

Port of Antwerp will provide a maximum of 50,000 euros per project to analyze and test the symbiotic possibilities. Indaver and Marlux-Stradus will contribute up to 25% of the costs.

The application for a raw materials declaration with OVAM was submitted in 2022. There is also an ongoing process to demonstrate suitability for the BENOR concrete technology certification. It is expected that the use of bottom ash granulate in concrete pavers will commence in 2023.

High-Grade Compost Indaver produces high-grade compost at its VFG and green composting sites. We make biomass from the woody residue, which is destined for biomass power plants. At Bio Power in Alphen aan den Rijn, we have not only a composting facility but also a digester facility. Here,

too, we process vegetable, fruit and garden waste to make high-grade compost. The VFG digester facility produces biogas from wet organic VFG waste, which we valorise into green gas and liquid CO2. > Web page compost

New, clean and safe raw materials from waste Sorting Measurements using Artificial Intelligence

T

o achieve high-grade recyclable material, quality is important. In 2022, alongside Fost Plus, Indaver tested the use of artificial intelligence (AI) at its PMD sorting centre in Willebroek (Belgium). AI is seen as an essential technology for the sorting sector to achieve good quality control, among other things.

Via the research, both organisations wanted to determine whether AI could help with monitoring the quality of the sorted materials.

In Willebroek, where Indaver sorts 15 waste streams, the sorting process is done automatically. Staff then analyse its quality by testing samples. For recycling the materials, this quality is extremely important.

By identifying any inconsistencies and optimising the stream of sorted materials, we can recycle more and continually provide the recycling centres with good quality materials.

Detecting Impurities The test focused on clear PET packaging materials. The AI system assessed the quality of the sorted fraction, complementing the human quality analysis. At the end of the sorting process, a camera was installed to take a photo every minute. These photos were collected in a digital portal.

Subsequently, AI software detected impurities in the sorted packaging waste that were missed by the sorting system.

The goal was to test the extent to which AI could recognize the packaging and objects in each photo.

However, the results were not sufficiently accurate, leading to the discontinuation of the project.

Nevertheless, Indaver continues to believe in the potential of AI in terms of quality control. They are exploring alternatives to integrate a new test setup into the PMD sorting facility. > Watch the video

New, clean and safe raw materials from waste Plastics2Chemicals - New basic chemicals from end-of-life plastics

T

oday, products with a short shelf-life are almost always stored in plastic packaging materials. For example, margarine tubs, meat trays, yoghurt pots and their lids and plastic-film covers.

This handy packaging material, known as end-of-life plastics, can only be used once.

A lot of plastic material is already recycled mechanically. However, more and more packaging material consists of multiple layers of plastic. These are often mixed polyolefins, such as polypropylene (PP) and polyethylene (PE) and the polymer polystyrene (PS). Such plastics are much harder to recycle mechanically.

MECHANICAL OR CHEMICAL Mechanical and chemical recycling techniques complement each other. Together, they take recycling to a higher level and produce secondary raw materials for new products. The choice for mechanical or chemical recycling strongly depends on the type of plastic, the market demand and the best-available technology to satisfy the quality requirements.

Thermochemical Recycling On its Antwerp site (Belgium), Indaver is building the innovative thermochemical recycling facility for end-of-life plastics.

Using the innovative technique from

the Plastics2Chemicals (P2C) facility, we can cut molecules into shorter carbon chains. This makes it possible to convert polypropylene, polyethylene and polystyrene into high-grade basic chemicals. The chemical and petrochemical industries use these basic chemicals as new, secondary raw materials.

The construction of our P2C facility is in full swing. This is being built on the Antwerp site (Belgium) so that we can make optimum use of all the infrastructure and knowledge already present. The facility is expected to be operational in 2024. Indaver is investing

50 million euros in the build of this first industrial factory for the recycling of plastics waste.

With the new P2C facility we can recycle even more materials and we are expanding our waste management portfolio.

New, clean and safe raw materials from waste Plastics2Chemicals - New basic chemicals from end-of-life plastics

Styrene, Naphtha and Wax The P2C facility focuses on polystyrene and polyolefins. We break the polystyrene down into styrene. The industry can use this clean and reliable r-styrene as a valuable raw material in the production of new materials. The quality of this secondary raw material is so high that it can even be used for food packaging materials. Thanks to the relatively simple chemical structure of polystyrene, it is infinitely recyclable.

The P2C facility recovers naphtha and wax from polyolefins. These are basic chemicals that the petrochemical and chemical industry uses to make highquality packaging materials.

We supply the final product as a raw material to customers such as Trinseo, INEOS (r-styrene) and TotalEnergies and Neste (r-naphta).

Preliminary treatment To close the chain, Indaver also invests in the preparatory phase. In Willebroek (Belgium), we are building a sorting facility that pre-treats separated, collected plastics waste streams and converts them into pellets. The pellets

are suitable for immediate treatment in the P2C facility.

Reducing CO2 Emissions The P2C facility ensures a reduction in CO2 emissions within the chain. We prevent these end-of-life plastics from being incinerated and the recovered raw materials replace the primary raw materials from fossil fuels. We close these materials loops and are thus making a valuable and sustainable contribution to the circular economy.

Chain Co-operation It is the collaboration throughout the entire chain, from the supply of end-of-life plastics to the uptake of the new base chemicals, that makes the P2C (Plastics-to-Chemicals) process a success. This collaboration across the chain remains crucial.

Completing construction of the facility does not mean the end of the research programme. The R&D team is working on further technical and process-related development, on the one hand, and, on the other, the team is setting up practical tests on end-products.

For this, the R&D team works closely with several (market) participants within the chain. This chain collaboration must lead to optimum cost-efficiency of the chemical recycling process and the end-products.

European Policy As part of the Green Deal, in 2030, 55% of all packaging must be recycled in a way that is feasible economically.

Chemical recycling is suitable for processing complex plastics into high-grade secondary raw materials.

With our P2C facility, we are contributing to the European Commission’s climate goals.

From 2024, the P2C facility will work with a capacity of 30,000 tonnes of polystyrene and polyolefins per year for the first three years. From 2027, there will be a second line for the polyolefins and for polystyrene we will scale-up treatment to 65,000 tonnes per year.

Eventually, we want to install multiple P2C facilities throughout our work area to treat these end-of-life plastics.

The new pre-treatment plant in Willebroek will also treat an external supply of plastic waste streams. To that end, in 2022 a multi-year contract was concluded with the French company Citeo, a waste management company for separated, collected household packaging waste. From 2025, Citeo will supply 8,000 tonnes of polystyrene waste per year. > Watch the video here and see how the top innovation P2C works

PARTNEREVENT P2C In September 2022, Indaver organised a partner event at its site in Doel for everyone involved in the advanced plastics recycling chain. Research institutions, waste stream suppliers, pre-treatment companies and purchasers of secondary basic chemicals all

attended. The latest developments in the field of chemical recycling were covered in various presentations and a panel discussion. The final network event gave everyone the opportunity to strengthen or expand collaborations.

C

ompost lies at the heart of our food chain. Customers therefore have very high-quality demands. To meet these demands, good separation at source is an important initial step.

Compost is an excellent replacement for fossil peat and chemical fertiliser. By composting collected VFG (vegetables, fruit and garden) waste, we are closing a valuable loop. The increasing contamination of the VFG waste has been a subject of discussion and campaigns for years. If the compost does not satisfy quality requirements, the agricultural sector will not buy it.

Then the recycling loop of VFG waste will break down.

Glass and plastic are common contaminants, but so-called compostable packaging material also presents a real problem. Biodegradable plastics do not add any value to the compost and they disrupt and contaminate the composting process.

The European Commission is working to

provide more clarity on the usability of biodegradable plastics.

Coffee pads and tea bags We can make the most progress with good separation at source, i.e. in citizens’ kitchens and gardens.

Educating citizens is therefore also important. The clear “do”/”do not” lists that Belgian and Dutch chain partners have created play a key role. They indicate clearly what can and cannot go into the VFG waste. In 2022, the Dutch coffee and tea producers worked on making a complete switch to compostable filter material for coffee pads and tea bags. From 2023 onwards, these can also go into the compostable waste bin in the Netherlands.

Indaver Waste Monitor We are also raising the collectors’ awareness. We perform quality checks on samples of the material that comes into our composting sites. Our Waste Monitor, a handy telephone app, includes an extensive reporting module.

We use this to inform our customers about loads that have been refused, with a description and photos of the contamination concerned. We can then investigate together which measures can be taken to prevent refusal.

I

n June 2022, Indaver took over all of the activities and staff of Mineralz in the north of the Netherlands. This takeover led to the creation of Indaver Mineral, which supplements the services of the Landfill Reconversion Business Line (also see p. 127).

Indaver Mineral recovers mineral secondary raw materials from (lightly) contaminated soil and dredge spoils. It offers its customers a complete package for soil remediation, with the exception of thermal cleaning. We treat the remediated soil using our extractive soil cleaning plant, among other things. This uses a physical method to separate the clean and contaminated components

from each other. We store the residue on the landfill site. For soil and dredge spoil, Indaver Mineral always uses biological soil remediation. The contaminated mineral stream is cleaned using bacteria in combination with the right temperature, aeration and humidity levels. Indaver Mineral also cleans drilling fluid. This muddy substance is released when the

boreholes are finally closed with cement at various depths. Drilling fluids contain chemicals and must always be cleaned.

Among other processes, Indaver Mineral recovers mineral construction materials from these drilling fluids.

Indaver Mineral stores all of the cleaned soil, grit, sand, minerals and small pieces of rubble in one of its soil banks.

Following approval and certification, the mineral raw materials are suitable for reuse as secondary construction materials. In this way, Indaver Mineral closes these material loops in line with the circular economy.

To give Indaver Mineral sufficient scope, new sludge depots were installed at TOP (Temporary Storage Site) Gaarkeuken in Oldekerk and TOP Delfzijl in 2022.

OUR APPROACH

Energy Crisis

Energy from Waste Streams

The Russian invasion of Ukraine and the subsequent tensions between Russia and the European Union have exerted great influence on global gas and electricity prices.

There is an energy crisis affecting citizens and businesses alike. As a result of the increasing energy prices, large-scale consumers, such as the petrochemical and chemical industries, are more open to green, locally produced energy.

Meanwhile, there is growing demand for energy and green energy due to the increasing electrification of processes. The share of renewable energy is increasing steadily but cannot keep up with this demand. The EU has implemented several measures, including accelerated investments in sustainable energy. This must make the EU less dependent on energy imports.

Indaver recovers as many raw materials as possible from the waste streams it manages. When that is not (or is no longer) possible, we create value by incinerating the waste. During the thermal treatment process we generate energy in the form of steam, hot water or electricity. We use this energy for our own processes. We supply the surplus to neighbouring companies and residential areas in the form of heat, steam, natural gas and electricity networks.

European Energy Objectives It isn’t just the energy crisis that is increasing pressure on citizens, governments, businesses and industries to save energy, the EU is also further refining its own energy goals, with a view to making the energy provision in Europe cleaner, more reliable and cheaper. At the end of 2022, the European Parliament agreed to the new target percentages in the Fit for 55-package, in which a distinction is now also being made between primary and final energy consumption with regard to energy-efficiency. The target percentage has also increased for renewable energy (also see p. 12).

We also have landfill gas, which is released in places where we store organic material. We recover as much of this gas as possible in the form of green gas or electricity.

Waste-to-Energy Strategy Indaver focuses as much as possible on energy generation from its facilities.

With this waste-to-energy strategy we are reducing the use of fossil fuels, and therefore also CO2 emissions, as much VEILIGE as possible.

Waste treatment generates (green) energy

T

he thermal treatment of waste streams generates a lot of energy in the form of heat, steam and electricity. As a waste management and treatment company, Indaver is therefore also making a contribution to energy generation. Our waste-to-energy plants, for example, generate their own energy supply. But primarily we supply energy to other businesses and to public and private networks.

We supply energy to businesses and we are a partner in large industrial energy projects. Every supply of recovered energy helps to reduce the use of fossil fuels in the chain and thereby contributes to a reduction in CO2 emissions.

We produce green gas from the organic Energy 2022 waste digested by the Bio Power plant in Alphen aan den Rijn (the Netherlands). In 2022, that provided enough energy for 1,400 households (1,500 m3 of natural gas per family/ year).

Indaver has six sites with one or multiple thermal treatment facilities.

These are located in Belgium, Germany, France and Ireland. Large-scale wasteto-energy projects are also under-way in the United Kingdom.

With the help of gas engines, we convert the gas from the landfill sites in Belgium and the Netherlands into Energy 2022 electricity or heat, of which we make good use.

In 2022, the sum of these energy yields, when converted into electricity, was equivalent to the average energy consumption of 276,600 families (3.5 MWh/family per year).

Waste treatment generates (green) energy

Ireland Storage Research The sun and wind are green energy suppliers that are preferable to fossil energy sources. However, both green sources are unstable suppliers.

Depending on the weather, there can be an excess or a shortage of energy. The waste-to-energy plants, on the other hand, produce a constant supply of energy.

In recent years the share of sun and wind energy has increased in the energy mix on the grid. In ideal weather conditions, with a lot of sun and wind, this type of energy can lead to an excess supply on the grid and cause instability.

In Ireland, when there is an excess in supply like this, the waste-to-energy plant in Meath is disconnected temporarily. To prevent energy from being lost, Indaver is investigating the

option of using batteries to buffer the renewable energy from its waste-toenergy plant. At times when there is an excess supply of sun and/or wind energy, we want to store the energy generated by our plant so that we can use it later when the wind drops or the sun isn’t shining. By doing that we can make optimum use of all renewable energy sources.

IndaChlor IndaChlor in Dunkirk (France) generates a lot of energy during the recovery of hydrochloric acid from chlorinated industrial waste streams. This energy is supplied directly to a neighbouring business as steam. In addition, using that steam we can also generate energy for our own consumption on the site.

This makes IndaChlor self-sufficient in its energy consumption. > www.indachlor.com > Watch the video

OUTLOOK

In Hamburg (Germany) we have been supplying energy from Indaver’s wasteto-energy centres to the city grid. In 2022, we completed the Investment Masterplan 1.0. Stemming from this, a number of technical points for improvement or maintenance projects were implemented, such as the maintenance of the two incinerator lines for the rotary kiln incinerators.

Indaver doesn’t invest only in new projects, we also invest in improving existing facilities. In 2022, in Biebesheim (Germany), we renovated the first incinerator line’s flue gas cleaning system adding an advanced scrubber. As a result, we are reducing electricity consumption and there is better flue-gas capture.

In 2023, this same improvement is planned for the second line in Biebesheim.

Other investments on this site (also in 2023) are the completion of the new tank park with the fully renovated entrance building.

Furthermore, we have built a new fire-fighting system to increase safety and fire protection. Two new water tanks and the pump system became operational in 2023. This new system makes Biebesheim independent from the public water network for fire extinguishing.

Also in 2022, we immediately began work on the Investment Masterplan 2.0.

Part of this plan is to replace steam with compressed air in certain facilities. The steam that we cannot use for our own processes can then be supplied to the local grid. This increases our energy supply to the city. The advantage of compressed air over steam is that it creates more resilience. This means we can treat more wastewater in the facilities.

Waste treatment generates (green) energy Project - North Antwerp Heating Network

I

n Antwerp (Belgium), Indaver invests in the Antwerp North Heating Network. This heating network will provide Boortmalt, the world’s largest malthouse, based in the Port of Antwerp, with residual heat. In the second phase, social residential areas in the north of Antwerp will also get their heating from the network.

At the end of 2022, the first pipe for the heating network was laid under the Antwerp-North marshalling yard, in the presence of all partners. The works began in the autumn and will continue until the end of 2023. From 2024, Boortmalt will be able to produce malt using heat from the Antwerp-North Heating Network.

Loop The heating network will be a closed loop. The heat comes out of the three rotary kiln incinerators on our site in Antwerp and is channelled to Boortmalt through a pipeline. Using this residual heat, Boortmalt can get a large amount of its energy consumption from renewable energy. The cooled water then flows back to Indaver through a second pipeline for reuse.

Residential Areas In addition, the network company Fluvius is laying a residential network. In time, schools, public buildings and 3,200 families in two residential areas in the north of Antwerp will also get their heating from this network. This will also be a closed circuit so that no water is lost.

Savings

Indaver and Port of AntwerpBruges have set up a separate transport company. The company is responsible for laying, running and maintaining the heating network between Indaver and Boortmalt.

The connection-point for the future municipal heating network also comes under this.

In total, the network has a capacity of around 60 GW. For the businesses that are connected to it, this represents a significant saving on the consumption of fossil fuels. The Antwerp-North Heating Network reduces CO2 emissions by 35,000 tonnes per year.

Once new steam suppliers and purchasers have joined the network and it is being used at full capacity, the heating network will be able to reduce CO2 emissions by 80,000 tonnes per year. Consequently, the heating network is a crucial part of the City of Antwerp’s municipal climate plan.

Open access The Antwerp-North Heating Network is distinctive because it will be an ‘open access’ network. Any business in the port that produces or wants to buy heat can join at a later stage.

Extra Investments

All partners – Indaver, Port of AntwerpBruges, Boortmalt, Fluvius, Stad Antwerpen (City of Antwerp) and Woonhaven – are investing heavily in both networks. The investment amount for the total project comes to around 100 million euros. The Flemish Government is supporting this project with a grant of 15.7 million euros.

Indaver also invested in a new, powerful turbine for the Antwerp site in 2022.

This means we can get more energy from the same quantity of waste. We can supply this energy to the AntwerpNorth Heating Network. We are also investing in a new high-voltage system (also see p. 54)

Waste treatment generates (green) energy E-Wood - Energy from Non-Recyclable Wood Waste

I

n Doel (Belgium), Indaver and its partner Veolia together invested 95 million euros in E-Wood, the waste-to-energy plant for nonrecyclable wood waste.

Stable Energy Supplier The treatment capacity of this fluidised bed incinerator is 180,000 tonnes of wood waste per year. As a cogeneration plant the facility can produce both heat and steam. At full capacity, E-Wood has a thermal capacity (energy capacity) of 80 MW each year. A turbine converts this energy capacity into 20 MW of electricity. This electricity is destined for the public grid.

In December 2022, E-Wood was officially put into operation.

E-Wood is a stable, green electricity supplier. There is sufficient supply of non-recyclable wood waste and, as a waste-to-energy plant, E-Wood is not dependent on the effects of the weather in the way that sun and wind energy are.

Green energy E-Wood treats construction and demolition waste and waste wood from container parks and from the industry in Belgium and the surrounding countries.

This includes: n uncontaminated treated wood waste that is unsuitable for recycling; n contaminated treated wood waste; n overflow from green-composting trommel screens; n woody fraction from green waste, which is separated prior to composting.

The wood waste is a renewable raw material that produces green energy following treatment. This green energy is used as a replacement for fossil fuels.

The prevented CO2 emissions from E-Wood are comparable to the CO2 emissions from 45 wind-turbines.

Doel Energy Cluster In Doel, Indaver runs three grate incinerators that treat 400,000 tonnes of non-hazardous and non-recyclable household waste and similar commercial waste. SLECO, a joint venture between Indaver and Veolia, operates three fluidized bed incinerators for the safe treatment of non-hazardous waste and sludge. Similar to E-Wood, this process also generates steam and electricity.

Three turbines convert the steam released during the thermal processes into electricity. E-Wood reinforces the energy production on this site with stable energy production. As a result, the power station is helping to further secure the economic development of this part of the port area. > www.e-woodenergy.com

Waste treatment generates (green) energy Project - Rivenhall: a greater energy yield from the same amount of waste

I

ndaver is building a new waste-toenergy plant in Essex (south-east England). At 600 million pounds, the Rivenhall Integrated Waste Management Facility (IWMF) is Indaver’s biggest investment project yet. Rivenhall IWMF will treat 595,000 tonnes of non-recyclable household waste and similar commercial waste each year.

State-of-the-art With the treatment of this waste, the energy-from-waste plant will supply households in the immediate vicinity with electricity. Indaver is also investing in a very efficient and innovative turbine. With higher steam parameters, higher pressure and temperature, we can recover even more energy from the same amount of waste. We can use every available joule of energy with this state-of-the-art technology. The new facility will provide 65 people with full-time employment.

Investing in the Environment In 2021, construction commenced on the Rivenhall IWMF, expected to become operational in 2025. Given Essex’s flat topography, the facility will be discreetly integrated into the ground to minimize visual impact. To achieve this, approximately three million tonnes of soil were excavated. A portion of this soil was utilized to remediate the adjacent quarry. Moreover, we undertook remediation efforts for the lagoon and constructed an access road and a car park. Additionally, we are

renovating Woodhouse Farm, a (17th-century farmhouse) derelict area, to restore it for the community.

Visitors are currently welcomed at the Information Hub on our site, where they can observe the construction progress of the IWMF from the balcony.

OUTLOOK Indaver is looking into the possibility of building a pre-treatment plant on the Rivenhall site, for treating bulky waste.

This facility would be able to dismantle sofas and other large items that are not suitable for recycling and treat them thermally with energy recovery. > www.rivenhall-iwmf.co.uk

ROYAL VISIT On 12 May 2022, Princess Astrid of Belgium gave the official sign for construction of the Rivenhall IWMF energy centre to start when she opened the local information centre.

This formal opening was part of the program of one of the most significant Belgian trade delegations ever to the United Kingdom. The delegation consisted of over 210 companies and organizations, including sector federations, universities, and chambers of commerce, with a total of more than 400 participants. Also in attendance were Flemish Minister-President Jan Jambon, Federal Minister of Energy Tinne Van der Straeten, Walloon Minister of Energy and Foreign Trade Willy Borsus, Flemish Minister of Economy Hilde Crevits, and Brussels State Secretary for Foreign Trade Pascal Smet.

Waste treatment generates (green) energy PROJECT - FOSTER sustainable sludge valorisation

T

he BESIX-Indaver consortium is developing, building, financing and maintaining a plant, FOSTER, for sustainable sludge valorisation for the water purification company Aquafin.

PARTNERSHIP Sludge is a valuable source of raw materials and energy. FOSTER is a very modern mono-sludge treatment plant.

One of its benefits is that the sludge, which comes from Aquafin’s sewage treatment plants, is not diluted with other substances. This means that optimum energy and valuable materials, such as phosphorus, can be recovered.

Energy The mono-sludge treatment plant will be installed on the ArcelorMittal site in the Port of Ghent (Belgium). The energy generated will be supplied in the form of high-pressure steam directly to the steel company as process steam.

ArcelorMittal can thus reduce its consumption of fossil fuels and in turn reduce its CO2 emissions.

Phosphorus In a second phase, the recovery of phosphorus will also be possible.

Phosphorus is an essential building block for life and a key component in mineral fertilizers used in agriculture and horticulture. However, phosphate ores are a finite resource and limited in

availability within Europe. Through the food cycle, phosphorus ends up in domestic wastewater, from which Aquafin will sustainably recover it using this new sludge processing facility.

On an annual basis, this amounts to the recovery of 2,000 tons of pure phosphorus.. > www.fostergent.be

Green energy on our own sites

I

ncreasingly, Indaver’s sites are (mostly) self-sufficient in their energy use. For the majority of them, this is achieved by generating energy from our own processes. We want to use any unused or undeveloped land on our sites more efficiently, for green energy from sun and wind, among other things.

Antwerp On our site in Antwerp (Belgium) we are investigating the possibility of placing even more solar panels on the slopes of the Hooge Maey landfill site. In time, this must expand into a solar park.

We are also looking to invest in two extra wind-turbines. We are taking these initiatives to make the Antwerp site even more sustainable, with renewable green energy, and to become less dependent on purchasing energy. The covered part of the Hooge Maey site lends itself perfectly to this sustainable multiple land use.

Willebroek In the Willebroek Recycling Centre (Belgium), solar panels and windturbines produce green energy for our own use. There are 4,000 m2 of solar panels on the roof of the new PMD sorting hall. Together with the windturbine on the site, they generate enough energy (approximately 600 MWh per year) to meet our own requirements. We can also supply our surplus electricity to the grid, and can

purchase electricity at times when there is insufficient sun or wind. > Willebroek

IWS Terneuzen At IWS Terneuzen, in the Netherlands, we have 670 solar panels on the roofs of one building. They produce 280 MWh per year, on average, which covers approximately 10% of our own energy use.

The safe sink principle SOCIAL CONTEX T

OUR APPROACH

Raw Materials from Waste

Keeping Hazardous Components out of the Loop

The circular economy closes materials and food loops by reusing raw materials again and again, even once they are in waste streams. These secondary raw materials must have the same high quality as the primary raw materials they replace, so that they can be used safely in production processes.

Ultimately, even in the circular economy there are residual fractions left over that are unsuitable for reuse, recycling or even incineration. With our Safe Sink Guarantee, Indaver’s waste management also focuses on these hazardous components.

Pure Loops

Destruction

Reuse of secondary raw materials is only possible if they are pure and safe for use.

Unwanted and hazardous substances must never go back into the materials or food loops. Waste streams can contain components that are unsuitable for reuse.

Legislation and regulations provide frameworks for treating these residual fractions safely and for their final storage.

The European Green Deal strives for an environment without negative consequences for the ecosystem.

We remove hazardous components from the materials loop by separating them and destroying them in our rotary kiln incinerators. The extensive gas scrubbing and water purification of these components, which is carried out according to the strictest standards, ensure that the emissions comply with all of the emissions standards in accordance with the Best Available Technologies.

We treat inorganic hazardous waste in our physicochemical plants. The chemical treatment process neutralises and immobilises the heavy metals and other components.

Keeping hazardous substances out of the loop Substances of Ver y High Concern

D

espite striving for pure secondary materials, even in the circular economy there will remain some components that must be removed completely from the loops. These are hazardous components and therefore must be destroyed. The Indaver Safe Sink guarantee ensures hazardous waste streams are treated and stored safely. We use our expertise on suitable solutions for hazardous waste streams internationally.

In its treatment of hazardous waste streams, Indaver also deals with substances of very high concern (SVHCs). These substances are classified as very hazardous for people and the environment. SVHCs can be released during industrial processes and can be found in water, soil and air and even in consumer products.

Several Applications Approximately 6,000 types of these hazardous chemical substances are known under the collective name PFAS (per- and polyfluoroalkyl substances).

The most well-known and most hazardous are PFOS, GenX and PFOA. None of these substances occurs in nature but they have been developed by humans for their useful applications. We all unwittingly use products that contain PFAS, for example, sun cream, baking parchment, waterproof clothing and lubricants. However, PFAS are also used in medical devices, implants and integrated circuits (microchips). The properties of PFAS ensure the products in which they are used repel water, grease and dirt, for example. PFAS are

also used in industrial processes.

PFAS compounds are often very persistent. This means they cannot be broken down naturally or biologically.

Over time, they can also build up in the bodies of humans and animals.

Exposure to certain PFAS concentrations can lead to hazardous effects on human health and the environment.

Best Available Technology PFAS occur in some of the waste streams Indaver receives from its customers for treatment. In line with our core value of ‘demonstrating concern for people, safety and the environment’, we take our corporate social responsibility seriously. We have the best available technology to destroy PFAS compounds permanently, including PFOS, PFOA and GenX. We destroy PFAS molecules in our rotary kiln incinerators in Antwerp (Belgium). The SVHCs are destroyed at high temperatures, over a long period of time and with intensive turbulence.

Temperature, time and turbulence are the three key factors that guarantee adequate destruction. This treatment technique is described in the BREF Waste Incinerations document 2019, which outlines the best available technology.

We neutralise inorganic components in our physicochemical plants. Then we store them safely in the landfill site under salt cell conditions.

Progressive Insight In 2004, the United Nations conference adopted the Stockholm Convention.

The aim of this legally binding document is to protect human health and the environment against persistent organic pollutants (POPs). The original POP regulation contains 12 substances and substance groups. Over time, 18 more have been added to the agreement.

PFOS were the first component to be added, in 2009.

Keeping hazardous substances out of the loop Substances of Ver y High Concern

Stringent discharge conditions for wastewater Indaver already had a discharge permit for PFOS and PFOA in 2007. This demonstrates Indaver’s proactive approach to these materials. Based on improved measurement technology and progressive insight, new members of the PFAS family were added to Indaver’s discharge permit in subsequent years.

We apply the best available technique every time. As a result, we can fulfil stricter conditions.

In June 2022, Indaver received another (tighter) permit. For the total PFAS we have reduced the annual pollutant load to less than 50 grams.

Indaver is working collaboratively on an air measurement method Europe still does not have a standardised measurement method and analysis technique for monitoring very low concentrations of PFAS in flue gases.

Therefore, the government gave the Flemish Institute for Technological Research (VITO) the task of devising a method for sampling and analysing PFAS

residues in flue gases. Indaver was prepared to be actively involved in this research. Between October 2021 and the summer of 2022, VITO conducted a measurement test on the flue gases from the rotary kiln incinerators at Indaver in Antwerp. The researchers then used a scientific model to convert the measured values into immissions, i.e. the pollution in the air at what is known as the ‘breathing zone’ of 1.5 metres. The study shows that we comply with the EFSA (European Food Safety Authority) values. > Relevant studies can be downloaded from the Indaver website

Reverse osmosis technique effective at IWS Terneuzen At Industrial Waste Services (IWS) Terneuzen (the Netherlands), we store waste streams, repackage them and transport the material for treatment.

PFAS-containing waste also ends up there. The Netherlands has no rotary kiln incinerators and the country’s hazardous waste is processed at Indaver in Antwerp (Belgium), as well as other places. To recover the PFAS substances

from industrial wastewater, IWS Terneuzen conducted a purification test in 2022 using the ‘reverse osmosis’ technique. This test was successful.

After treatment, most of the PFAS substances had been completely removed from the water. Posttreatment was only required for several smaller molecules. Since then, Indaver has invested in a permanent reverse osmosis plant at IWS Terneuzen.

Action Plan Based on our core value of ‘continuous improvement,’ we have developed an action plan. We will conduct further research, invest, and monitor to further reduce the presence of residual PFAS in water, soil, and air.

Keeping hazardous substances out of the loop Safely disposing of medical waste

MediPower Guarantees Safe Treatment In Antwerp (Belgium) we have a rotary kiln incinerator, the MediPower, which is specifically intended for the treatment of Hazardous Medical Waste (HMW).

This also includes waste that may be contaminated with the coronavirus.

In early 2022, most European countries still had strict measures in place, which were lifted in March. Although the COVID-19 pandemic seems to have subsided, people are still getting (seriously) ill from the virus. We are capable of handling any surges in hospital admissions and the subsequent

increase in infectious medical waste.

The MediPower system effectively destroys the harmful components by combining very high temperatures, extended duration, and intense turbulence, followed by thorough postcombustion. This ensures that dangerous substances do not re-enter the environment. The MediPower’s automated feeding system, equipped with roller conveyors, pushers, and lifts, directs packaged waste directly into the incinerator. Our staff members naturally wear all the necessary personal protective equipment required for processing this type of waste. > Watch the video on MediPower

Poland Transport and the Destruction of Pesticides A European ban on the use of a particular chemical substance ensured that a certain form of pesticide could no longer be used. In 2022, one of our customers called in Indaver’s help to responsibly destroy large quantities of pesticides from a Polish manufacturer. It concerned approximately 350 tonnes of pesticide that were stored across seven locations in Belgium, Germany, Greece and Italy. We organised the transport within our European network. The

pesticides were destroyed in our rotary kiln incinerators in Hamburg (Germany) and Antwerp (Belgium).

VIDEO

Poland Remediation of Pesticide Storage In March 2022, Indaver in Germany successfully completed the remediation of 8,000 tonnes of pesticides. These pesticides were stored in an open area in Myslowice in Poland, primarily in intermediate bulk containers (IBCs).

The biggest challenge was the tight timeframe and the associated treatment capacity. We brought in several facilities in Germany and Poland, as well as our own rotary kiln incinerators and those of our partners. > Watch the video

OUTLOOK The subsequent tender was for the destruction of 60,000 tonnes of pesticides on one site. In Poland, there are approximately 100 sites awaiting remediation.

Ireland Clarecastle Site Remediation Since 2020, the pharmaceutical company Roche has stopped its production in Clarecastle. Thereafter, the production location was dismantled.

Indaver in Ireland took on the waste management from the demolition contractor as a sub-contractor. For the site remediation, Roche selected us as the main contractor. We will work closely with the Roche team and with a selection of specialised sub-contractors.

The distinguishing factors in the tender are our continuous attention to environmental and safety measures, whereby we ensure the burden on the local population is kept to a minimum.

Landfill sites, the final destination in sustainable waste management

I

n the circular economy, materials are constantly reused. However carefully this is done, components do still remain that must not go back into the loop. In some form or other, they will end up in landfill (safe sink), the final destination in sustainable waste management.

Guaranteed Landfill Capacity

Indaver has various landfill sites in Belgium and the Netherlands. Belgium has two landfills for residual waste that come under category 1, hazardous substances. They are located in Antwerp and Doel. In addition, there are landfills for non-hazardous residual waste: one in Doel and Hooge Maey in Antwerp.

In the Netherlands, Indaver has two landfill sites in use: Afvalberging Noord- en Midden-Zeeland [North and Mid-Zeeland Waste Storage] and

Stainkoeln (Groningen). The Derde Merwedehaven landfill site, now known simply as Merwedeheuvel, is no longer operational. Now that this landfill site has been closed and the creation of the Merwedeheuvel recreation area is complete, talks about the handover to the South-Holland province began in 2022. The area in front will be further developed as a water-bound industrial area.

We are not allowed to acquire any new landfill sites in either country. Existing sites can potentially be extended, however. In Belgium, we have structured the space between three existing landfills, Antwerp, Hooge Maey and Amoras, as an additional landfill site. At the 3 Valleien landfill, we can offer our customers continuity for the next 20 years.

In the Netherlands, Indaver has guaranteed continuity through the purchase, in 2021, of the industrial area next to Stainkoeln. The site, called TOP Groningen, opened in 2022 following a substantial renovation and it provides space for the storage and recycling activities that were previously carried out at Stainkoeln. Exclusively secondary construction materials were used for

the renovation. The majority of this came from Indaver’s soil banks.

Through the relocation of the activities there was space created on the landfill site for expansion. In 2019, Stainkoeln was granted a permit for an extra 1.5 million m3 of landfill capacity.

Knowledge and expertise combined

HIGHEST POINT

Indaver has bundled together all of its expertise on the life cycle and sustainable management of landfill sites to form the Business Landfill Reconversion. This team of experts uses its knowledge for the development and construction of landfill sites, their sustainable management and for the final closure of landfill sites that have reached full capacity.

In 2022, the North and Mid-Zeeland landfill site in Nieuwdorp (the Netherlands) was the backdrop for the Zeeland TV programme Rem & Vloed. In five short episodes, photographer and artist Rem van den Bosch investigated the potential effects of climate change on Zeeland. In the first episode, he talks to researcher Aimée Slangen in Nieuwdorp about rising sea levels. Moreover, it seems that the landfill site is the highest point in Zeeland.

TOP DELFZIJL The TOP (Temporary Storage Site) Delfzijl (the Netherlands) was established in 2022 for the storage and transfer of (mineral) waste streams. We can now also accept sludge streams and biological cleaning of lightly contaminated soil is carried out there.

TOP GRONINGEN IS OFF TO A FLYING START TOP Groningen (the Netherlands) had not yet opened when the Frisian waste management company Omrin needed a transfer location temporarily. Indaver quickly made the site suitable for this temporary transfer, which lasted several months. On average, 1,750 tonnes of household waste (residual and VFG waste) and similar commercial waste from the city of Groningen and the surrounding area were taken there for transfer each week.

Consideration for Our Environment

Society needs a safe and clean environment to live, work and enjoy. Governments have established frameworks so that manufacturing companies and industries can set themselves up and develop in locations intended for that purpose. However, older industries can still be found near to residential areas.

It goes without saying that Indaver works as hard as possible to limit its effect on the local environment – people, animals and plants – as much as possible. We conduct our activities in accordance with the strictest environmental standards. We constantly measure our emissions and check the properties of our emissions and residues. We use energy and water sparingly and take measures to prevent contamination of the soil and groundwater.

Regardless of their location, industries and businesses have a corporate social responsibility to operate cleanly and safely so that there is no burden on the environment.

Thanks to these efforts, and with the help of tried and tested, reliable technology, we can limit the impact of our activities on the soil, air and water.

Where possible, we encourage biodiversity in our surroundings.

ndaver wants to limit the environmental impact of its activities as much as possible.

That is why we monitor our activities closely, measure our emissions continuously and check the properties of our emissions and residues. The results of these measurements help us to adjust processes or to further limit the impact of our activities on the environment.

Indaver invests heavily in new technologies to limit the environmental impact as much as possible.

Air We check and continuously monitor the flue gas emissions from our facilities.

We limit the emissions thanks to investment in new methods and technologies. For parameters that are currently still difficult to measure, we provide our cooperation to research institutions to develop validated measurement methods and analyses, for example for measuring PFAS (also see p.

81). > More information on pages 88-102

Water We use our water as sparingly as possible. We invest in new methods and technologies to reduce that consumption further. We use extensive water purification to keep our discharge water in line with the current standards.

In Antwerp, Belgium, Indaver made significant investments in expanding the water treatment facility to significantly reduce the presence of PFAS residues in wastewater. Additionally, in Terneuzen, the Netherlands, Indaver invested in

reverse osmosis technology to clean industrial wastewater from PFAS substances. The success of these initiatives has led to the decision to invest in a permanent water treatment facility. (also see p. 104). > More information on pages 103-105

Soil We take all the appropriate measures to prevent soil contamination. > More information on pages 106-107

We use buffer tanks to capture as much clean rainwater as possible from the roofs on our site. We use this water for the toilet facilities in the buildings, to control the dust on our landfill sites or as process water in our treatment facilities, which can consume a lot of water. By doing so, we save on our consumption of valuable mains water or other primary water sources, such as groundwater and surface water.

Infiltration We must strive for the maximum infiltration of clean rainwater unless this is clearly impossible from an environmental perspective – such as, for example, high levels of groundwater or poor water permeability of the soil.

Indaver sites in Doel (Belgium) and Antwerp have watercourses. In Willebroek (Belgium) infiltration crates have been fitted under the car park.

Infiltration of rainwater is not possible on all of Indaver’s sites, however.

Buffering Where infiltration is not technically feasible, we buffer the rainwater and drain it off slowly into the sewage system and/or the surface water (river, canal). In this way we shift the peak of our drainage to a later time and we reduce the risk of overburdening the sewage system or floods.

Discharging Safely Only when all rainwater capture systems are full, during heavy rain showers, do we drain it off into the sewage system and/or the surface water.

Using rainwater sustainably

The Netherlands Reverse Osmosis at IWS Terneuzen At Industrial Waste Services (IWS) Terneuzen, we do not conduct any thermal treatment on PFAS-containing waste streams. But since 2018 we have conducted PFAS-related activities, such as cleaning tankers and the waste transfer of liquids containing PFAS.

In 2022, in a pilot facility on this site, we investigated how industrial wastewater containing PFAS could be purified.

The aim of the investigation is not only to purify the wastewater in accordance with the standards but also to be able to reuse the clean water on this site.

Ultimately, we treat the residues containing PFAS in our rotary kiln

incinerators on our site in Antwerp (Belgium).

The purification using reverse osmosis was successful. The decision to choose reverse osmosis stems from the composition of the wastewater and the fact that, after purification, the composition of the water meets our requirements. This solution is the most effective for this site. Indaver is therefore working on tailored solutions for generic issues.

IWS Terneuzen will start to use the permanent water purification plant in 2023.

Belgium Water Purification in Antwerp In 2022, on the Antwerp site (Belgium), Indaver invested in research and pilot facilities for the purification of various water streams.

Central Water Purification In 2022, we invested heavily in research into the further purification of water, with a view to removing residues of hazardous waste substances such as PFAS. The composition of the

PFAS WEBINAR Treating PFAS-containing waste is complex. In November 2022, Indaver held a webinar about this dossier. In it we demonstrate what our treatment routes are and what improvements we have made to the treatment. It also covers how the PFAS family arose and the legal framework, as well as our view on the standardisation. > Indaver webinar PFAS

wastewater, which contains certain salts, makes it impossible to use reverse osmosis in the way that it is used at IWS Terneuzen. Therefore, in a pilot facility we have extended the central water purification plant with extra sand filters, activated carbon filters, interim buffers and then more activated carbon filters.

The results of this pilot facility are good, and the definitive facility will follow in 2023.

Nitrogen Removal We also invested in research, development and a test facility to further reduce the discharge of nitrogen in the water. This test facility, where we use biological water purification to remove all of the nitrogen present, was installed in 2022. The permanent facility is planned for 2023. The investment required for the new treatment amounts to 3.5 million euros.

Ireland Reduction of Water Consumption

Groundwater Purification Due to the low groundwater level, the Antwerp site consumed more mains water in 2022 than in previous years.

This shows the need to buffer more water and to ensure that the groundwater is clean enough to use.

In 2022, we invested in a pilot facility for cleaning groundwater in combination with the run-off water from the landfill. The pilot facility

comprises aeration, a sand filter and three activated carbon filters. Once cleaned, we put the clean water under pressure (6.7 bars) so that we can supply it to our rotary kiln incinerators for, among other things, gas scrubbing and cooling the flue gases.

For the waste-to-energy plant in Meath, we made various improvements in 2022 to reduce water consumption significantly. The adjustments provide savings on both groundwater consumption and on the use of demineralised water.

Biodiversity as the basis for ecosystems

iversity in flora and fauna, together with microorganisms, form the basis for all ecosystems. Biodiversity is part of the European Green Deal and is an essential part of every environmental permit, whether it concerns a new site, a modification or an extension.

The Netherlands Flowers for Bees and Butterflies

In its policy document on biodiversity, Indaver expressly makes a commitment to the United Nations Convention on Biological Diversity.

Our policy on maintaining biodiversity is expressed: n in our selection of raw materials; n in relation to our emissions; n on our production sites, by limiting or compensating for the effect of our constructions on the natural environment; n by making a contribution to the fertility of the soil, resistance to disease and soil erosion, through our production and distribution of compost; n by supporting local projects that improve biodiversity.

United Kingdom New Trees, Shrubs and a Pond Indaver is building its new waste-toenergy plant in Rivenhall, Essex. The facility is partially sunk, embedded in its surroundings. In addition, Indaver is investing in the restoration of this former quarry’s immediate environment.

On our IWS site in Terneuzen, bats can sleep peacefully in the daytime. Bat boxes hang on the façade of the office, which provide better shelter than the sunscreens they were using previously for their accommodation. In 2022, a dike of excess earth was built on this site and then planted with flower seeds.

The flower mixture attracts bees and butterflies. Kestrels and redstarts nest on the site as well.

Part of the 70-hectare site is being made suitable for agriculture again.

The original natural life is also being supported by planting 30,000 trees and shrubs. Reconstruction of the neighbouring pond began in 2022.

These adjustments will promote biodiversity in the area.

The Netherlands Wild Port of Europe The VFG composting site Europoort in Rotterdam is one of the filming locations featured in the dramatised nature film Wild Port of Europe. The feature film shows the unexpected richness, resilience and dynamics of nature in the largest and busiest port in Europe.

Eagles, polecats, seals and many other animals are followed in the port area.

One of the things you learn is that jackdaws are particularly partial to compost.

Ireland The First Harvest of Our Own Honey A wildflower meadow and pastures were planted a few years ago on the site of our waste-to-energy plant in Meath.

They attract honeybees, bumblebees, butterflies and other insects. In September 2022 we were able, for the first time, to harvest honey from the beehives we placed on the site. Bee Green Ireland maintains the beehives and helped with harvesting. We only took the excess honey from the beehives, leaving enough for the native honey bees to overwinter.

Plan for Pollinators Since April 2022, Indaver in Ireland has been participating in the All-Ireland Pollinator Plan. This programme wants to strengthen biodiversity and increase the number of species of wild bees and other pollinators. To come up with ideas to promote biodiversity, the Safety Health Environment (SHE) staff followed a webinar, which was organised in part by the National Biodiversity Data Centre of Ireland.

In the annual assessment we were complimented on our efforts to promote biodiversity on our sites, through the reduction of pesticides, our maintenance of hedges and our webinar on biodiversity.

More Natural Grounds In 2022, in the area surrounding Meath, 14.5 hectares of ground were once again made available to local farmers who cultivate the agricultural ground sustainably. This area is being given the chance to develop naturally until new land-use plans are implemented in the next few years. This gives our waste-toenergy plant’s bee population a much wider area of wildflowers.

OUR APPROACH

Corporate social responsibility

Our Core Values

Our society, from government authorities to staff and from banks to customers, expects entrepreneurs to accept their corporate social responsibility by taking diversity, climate neutrality and circularity, for example, into account in their business activities and production processes. Chain partners, large buyers and other business relations are asking more frequently and more explicitly about the ways in which a business fulfils its corporate social responsibility.

Indaver heeft een duidelijke missie: Indaver, toonaangevend in duurzaam afvalbeheer.

The reporting on this non-financial information must be of the same quality as financial reports. The new CSRD guideline for sustainability reports also sets more demands and focuses specifically on aspects concerning Environment, Social and Governance (ESG).

Businesses work in line with these expectations, collect more data and information for these purposes, set long-term goals and measure their progress.

This development fits in with the circular economy, in which operational management is based on a transparent, sustainable, socially responsible and reliable way of working.

Our five core values provide a concrete way to fulfil this mission. n Demonstrating concern for people, safety and the environment. n Building relationships based on mutual trust. n Ensuring transparency in communications and actions. n Concentrating on achieving results. n Continuously improving.

The core values guide us in our strategy, our decision-making process and our relationships with everyone involved. They form the basis for our economic goals, our social goals and our environmental goals. Our core values guarantee that we do business with integrity and corporate social responsibility in a complex world.

We undertake all this from a healthy, stable and solid financial basis and we VEILIGE KRINGLOOP report openly and transparently.

EcoVadis Corporate Social Responsibility In 2022, Indaver received the silver medal for its efforts on Corporate Social Responsibility. For this we were questioned critically on various subjects. n Environment. n Ethics. n Working conditions. n Sustainable procurement policy.

EcoVadis is an independent, international evaluation platform that assesses suppliers and organisations from 95 and 150 business sectors, respectively. Indaver falls within the category of Waste Management and Treatment. With a total score of 61 points, we have way above the average of 48 points in this sector.

Sustainable business involves the entire chain. Just like Indaver, our industrial customers also look into their suppliers within the chain. Nowadays, participation in an EcoVadis assessment

is a requirement for many large IWS customers. Our customers keep a close eye on our score. We have been taking part since 2013.

In accordance with our core value of ‘Continuously improving’, we investigate where we can make further improvements. In 2022, we worked on our policies concerning modern slavery and human trafficking, among other things, and our “whistleblower” regulation came into force.

OUTLOOK EcoVadis also makes suggestions for improvements in its assessment. In 2023, we are focusing on the KPI-reporting on ethics and working conditions, among other things. We are looking at which improvement projects we will first implement, together with those involved.

Whether it concerns existing sites or new projects, we maintain an open dialogue with those involved from the local area.

We want to be a reliable partner in the regions where we work.

Open Communication on PFAS

Neighbourhood Councils Indaver in Belgium has a neighbourhood council for its sites in Antwerp and Doel. The neighbourhood council in Antwerp comprises around 50 members who represent the surrounding companies, local authorities and interest groups such as the Environment Council and Natuurpunt (an environmental organisation). In 2022, we celebrated 30 years of this cooperation with them.

The neighbourhood council in Doel, which includes representatives from businesses in the surrounding area, meets twice a year. In addition, Doel has a policy committee, made up of various stakeholders, which monitors the

activities of the fluidised bed incinerator facility.

Ierland Charities Every year, Indaver in Ireland contributes to a fund as part of its connection to the local environment.

The fund then decides which charities will receive a contribution. This covers a broad range of interests, from community provisions and restoration and heritage projects to the ‘animal ambulance’ and sports clubs We are also involved in litter-picking activities and safety projects in the region.

In 2022, the treatment of PFAScontaining waste was high on the agenda. Indaver offers a solution for PFAS-containing waste and other substances of very high concern, by destroying them in our specialist facilities. We have continuously communicated openly with our own staff, the government authorities, customers, partners, monitoring bodies and the media. We spoke about the treatment methods and appropriate measures to keep the impact on the environment as low as possible. We provided clarification on this topic on various consultation forums. In addition, we answered (often critical) questions from local governments, journalists and customers. In a webinar on the Indaver website, we provide more detailed information on the results of the water purification and specific studies and emissions data from the flue gases. > PFAS webinar

The Netherlands NVRD Conference

On the first weekend of October 2022, the doors of Indaver’s Doel site in Belgium were opened wide. The Saturday was reserved for family of staff (during the day) and for the staff of the Doel site themselves (in the evening).

On Sunday, members of the general public were also welcomed. We set out five routes: the Lichtlaan (Light Lane), the Afvalstraat (Waste Street), the Stoomdreef (Steam Track), the Goudweg (Golden Path) and the Baron Energieplein (Baron Energy Square).

On all of these routes we demonstrated how Indaver and SLECO recover materials and energy from waste.

In addition, visitors were able to take part in a number of activities. The fact that there is a need for people to come and see our site for themselves was evident from the large number of visitors. On Sunday evening the visitor counter stood at 2,000 people.

In May 2022, together with the Zeeuwse Reinigingsdienst (the Zeeland Waste Collection Service) and the NVRD (the Dutch Association for Waste management and Cleaning), Indaver organised the NVRD annual congress.

This was held in Vlissingen. The theme of this congress was quality, both of raw materials and of people, resources and organisations. In addition to the different topics that the various speakers discuss, the annual congress is primarily also a networking event. It is now a tradition that the Zeeland collection service and Indaver, as the Zeeland compost producer, take the annual congress to Zeeland every 10 years. This is a great promotion for the province and publicity for the collaboration between these two parties.

PARTNER EVENTS IN DOEL In the week before the open day, Indaver in Doel organised three partner events. First, we received everyone involved in the chain for our Plastics2Chemicals project (also see p. 62).

After that, there was an exclusive preview of the open day for our relations in the public and industrial sector and the people who purchase heat from the ECLUSE heating network.

Each year Vlaanderen Circulair organises the ‘Circular State of the Union’. There was great interest in the event, held in April 2022. The exciting and full programme comprised six work agendas: circular construction, the bioeconomy, chemistry/plastics, manufacturing industry, the food chain and water loops.

The sector federation of the chemical industry and life sciences, Essenscia Vlaanderen, organised its annual congress in May 2022. As CEO of Indaver and as chairperson for Vlaanderen Circulair, Paul De Bruycker took part in the panel discussion on the circular economy. The other panel members were Zuhal Demir, Flemish minister for the Environment and Energy, and Prof. Dr Elvira Haezendonck, professor at the Vrije Universiteit Brussel (Free University of Brussels) and Solvay Business School.

Chairperson Paul De Bruycker, currently CEO at Indaver, made an ‘Ode to the Do-ers’. He also emphasized the importance of creating value in the circular economy that truly has economic value.

OUR APPROACH

European Legislation Drives Improvements

Best Available Techniques

The European legislation on waste products, waste management and waste treatment is updated frequently. In 2018 and 2019 the BREF document for waste treatment techniques and waste management was revised. A BREF document sets out what the most environmentally friendly and best available techniques are that businesses in a particular sector can use. The maximum emissions are also set out.

Member states have four years to translate the provisions in the BREF into national legislation.

For the Waste Framework Directive, consultation rounds were held in 2022 for the revision that is scheduled for 2023 (also see p. 14).

With the new or amended directives, the EU is working to refine the standards and to improve (treatment) techniques.

In its processes and facilities, Indaver closely monitors the refinements made to European and national statutory standards. We meet all requirements.

Business Continuity and Process Assurance Customers require a guaranteed/reliable service provision, regardless of where Indaver conducts its activities. With our Business Continuity Plan, we guarantee the continuity of our service provision. We invest in process assurance to ensure operational reliability. To this end, we research and protect our processes, chart the risks and, where possible, improve our processes.

ffective digitalisation improves our administrative and operational processes and service provision. As a result, we can work more effectively and put more emphasis on quality, speed and efficiency. Furthermore, digitalisation helps us to prevent errors. Led by our core value of ‘Continuously improving’, we continue to work on improving our IT infrastructure and software, with a strong focus on safety.

Safe and Efficient Use of IT The world is changing fast, and this is probably most noticeable within the IT sector. Therefore, it is of vital importance that we constantly pay attention to the safety of our IT infrastructure. The software must be up-to-date and supported by suppliers.

The processes, services and projects that Indaver carries out are digitalised and there is increasing integration between the different systems, both internally and externally.

With new facilities and takeovers, we guarantee that everything is in line with our safety and access requirements. To

make safe and efficient use of digital potential, we provide our staff with the necessary instructions, tools and training. We introduce new apps to simplify processes, to work more efficiently and to reduce the chance of errors. In addition, we respond to the growing demand for digital solutions.

Safe treatment Waste Identity Card (limited number of streams) In 2022, the safety programme for the Indaver site in Antwerp (Belgium) focused on the development of the digital Waste Identity Card (WIC). The WIC is the acceptance form for the safe and efficient treatment of hazardous waste in our facilities. Together with the customer, we establish all data per type of waste, identify the waste product’s characteristics and risks, and the customer validates the treatment method.

Through chain collaboration we have digitalised this process. With that, we are improving the safe and efficient treatment of (liquid) hazardous waste.

IndaScan 2.0 Intelligent and Efficient Industrial Waste Tracking Knowing where a waste stream is at any given time is a requirement for many waste producers. They remain responsible for their waste at every step in the chain. But also, for example, for our customers in the pharmaceutical industry. The IndaScan 2.0 gives realtime insight into the status of a waste stream. Indaver is developing this track & trace instrument together with a few industrial customers.

SIMON VAN HOEVE, HEAD LOGISTICS

“For ICL-IP Terneuzen, Total Waste Management means that we trust that Indaver will transport our waste safely and reliably. Thanks to extensive e-reporting, we gain insight into our waste’s movements and we can clearly communicate the legal reports to government authorities.”

VIDEO

Every package from a waste stream that is intended for our treatment site in Antwerp (Belgium) is given a unique QR-code. This remains linked to the package throughout the entire management and treatment process.

During that process we add information, such as the collection date and location, customer reference, risks, weight, storage location, treatment method, etc.

In this way, we guarantee full traceability of the hazardous and industrial waste that is entrusted to us.

In 2022, we introduced the IndaScan to multiple customers where an Indaver Total Waste Management-operator takes care of the daily operational waste management on the customer’s site. > Watch the video

Irish Award In 2022, the IndaScan was selected as the winner of the CBRE Best Technology Solution for 2022. CBRE is a facility management company that evaluates (among other things) our Total Waste Management (TWM) contract with the pharmaceuticals company MSD. The award was presented in Dublin (Ireland), in October.

“IndaScan 2.0 makes my work easier. There is less chance of an error because I don’t have to re-label batches each time. That increases safety. I can follow each batch from collection to treatment. In short, IndaScan 2.0 works for me.”

OUTLOOK

NON-CONFORMITIES DATABASE

We are investigating whether a similar application to IndaScan 2.0 is possible for the Indaver industrial-waste transfer stations.

Storage+ Cooperation and Knowledge Sharing In 2021, Indaver began using its new tank park ‘Storage+’ at IWS Terneuzen (the Netherlands). During the process of pumping liquids over from the tanker to the day tank and from the day tank to the storage tank, a lot of information is exchanged.

For this reason, we investigated the possibilities for digitalising this process.

In close collaboration with various departments, we opted for the radiofrequency identification technique (RFID). We combine this technique with the further automation and digitisation of the various throughput times. This means we only need to input information once. Linking the Laboratory Information Management System to the operators’ system digitalises the four-eyes principle.

Ultimately, the liquid can only be pumped into one specific storage tank.

Modern Workplace Improvements to digital processes often have a long run time because many system changes can be far-reaching. For two years now, we have been working on safer and more user-friendly digital systems for our staff and customers. In the meantime, a lot has been achieved that makes it safe and easy to work, including working from home and working collaboratively.

In 2022, the focus shifted to the rollout of NEXT, which is the name for the Indaver digital work environment, in Ireland and the UK. This was successful.

In 2022, Indaver began using a new database for nonconformities. In this database, staff can report deviations from commercial, technical or safety criteria. It specifically concerns deviations on values that have not been agreed with our customers in advance. The report goes to the department, which takes the right course of action. With this new database, the reports are easier to submit via an app.

Digital safety

T

he increasing digitisation of business activities demands suitable and up-to-date data protection. This is vital as internal and external processes are increasingly being integrated.

Security against cyber-attacks has therefore also become a constant top priority.

There has been a strong rise in the number of cases of ransomware, cyber intrusions, data leaks and other unwanted digital activity. Accordingly, cyber security has become a top priority in many of our areas of work. In our Information Security Policy, we set out how we safeguard our security.

The human factor is one of the main risk elements in cyber security. We regularly conduct awareness-raising campaigns to keep our staff alert to phishing practices. In 2022, we took a baseline measurement so that we can see from that point onwards whether our campaigns are effective. We sent (fake) phishing emails to our staff. People who responded to them were given a short training session on recognising such emails, to help them become more adept at protecting our digital assets.

Hosting Data Externally In 2022, we prepared everything to host our data centre with an external party.

Outsourcing our data centre with a specialist party offers more opportunities to protect our data and to recover it. Data recovery is essential for

guaranteeing business continuity, for example due to ransomware. Data recovery is part of our Business Continuity Plan and our Information Security Policy.

In 2022, each of Indaver’s business lines investigated what was needed for data recovery and for how long. This gave us insight into the required capacity and availability of data recovery. The actual outsourcing will happen in 2023. > see our Information Security Policy here

OUTLOOK In 2022, we made all the preparations for the new Indaver Business Intelligence Platform. The implementation will follow in 2023. The Customer Zone will be implemented at a later date.

Germany German Customer Zone In 2022, Indaver in Germany began the switch to a new centralised system for data management. One of the improvements is the intended Customer Zone. Through this online platform customers will have (restricted) access to the current data about their waste files. The data not only concern the administration, transport, treatment and all invoicing, but also where a specific waste stream is at any given moment.

The customer can share this information with the regulatory authorities and auditors.

Openness and knowledge sharing International knowledge platforms

Indaver has been active in the management and treatment of (hazardous) waste products for c. 35 years. Its specialists (who operate internationally) have very specific technological knowledge and experience. Knowledge management is one of our strategic competencies and the driving force behind our continuous improvement and innovation strategy.

From this background, Indaver has various operational competence centres, known as ‘international knowledge platforms’. The participants are our specialists, who share their knowledge with each other internationally. These knowledge platforms are there for various subjects.

In 2022, we breathed new life into the knowledge platform for energy and we implemented a knowledge platform for residues (bottom ashes and flue gases).

Both topics are very current.

Growth and innovation SOCIAL CONTEX T

OUR APPROACH

Competitive market

Further Strengthening a Stable Position

The waste sector is a competitive market. On the one hand, there is talk of further consolidation but, on the other, there are new initiatives in the field of materialsand-energy recovery. The energy market is under a great deal of pressure. In addition, in some countries there is talk of an imbalance in the demand and supply of some waste streams.

The European goals for the climate, the recovery of materials and energy, and waste legislation make it necessary to find innovative business models, chain transparency and a wide range of collaborative partnerships.

From its stable economic position, Indaver offers sustainable solutions for its customers’ waste streams. We accept our social role by recovering as many materials and as much energy as possible from these waste streams and bringing them back into the loops. With targeted acquisitions, we ensure we are increasing in scale. This improves our market position and strengthens the continuity of our service provision to our customers. Thanks to our staff’s specific expertise, we can also serve interesting niche markets.

Made to Measure Peace of Mind

Indaver is focused on the transformation to the circular economy, which we can achieve through chain collaboration with our customers and through partnerships, among other things. We encourage new technological innovation projects and business cases. These new techniques must be reliable, ecologically sound and financially responsible. The new business cases fit in with our qualities and our strategy.

Waste management is a complex subject. The legislation and regulations are subject to changes and the market is constantly evolving. Customers need service providers who can give them peace of mind and who are transparent about sustainable treatment. They want to know which products are made from waste and how much energy is recovered during the treatment. They require flexible and relevant solutions that fulfil their specific needs.

ndaver has a healthy financial basis and is active in various parts of Western Europe. Growth is not a goal in itself, but we are always open to the opportunities the market presents to us, so that we can further improve our market position, expand our portfolio and extend our work area. Our basic principle is that every new acquisition must fit in with our vision of the circular economy and with our core values.

Takeover Mineralz Noord becomes Indaver Mineral With the takeover of Mineralz Noord in June 2022, the Business Line Landfill Reconversion is strengthening its position in the northern Netherlands and taking advantage of the opportunities for growth there.

The activities of the new business unit, Indaver Mineral, fit in seamlessly with those of Landfill Reconversion. Both organisations worked together regularly beforehand.

Not only does Landfill Reconversion now have supplementary techniques for soil cleaning and materials recovery but by taking on six experienced staff, Indaver is gaining complementary inhouse knowledge.

The new Veendam site comprises a soil bank, bottom-ash reprocessing plant, biological soil remediation, drilling-fluid cleaning and a water purification plant.

In Groningen, on the Stainkoeln landfill site, Indaver has now become the owner

of the extractive soil remediation plant.

And in Leeuwarden, Mineralz Noord’s and Indaver’s soil banks have been combined (also see p. 67).

we want to constantly improve the quality of compost. In addition, we work together with chain partners to tackle contamination in VFG and green waste.

Takeover Indaver is now the Full Owner of OGAR

Transfer Koegors Waste Transfer Station

Since the end of 2022, Indaver in the Netherlands has become the full owner of the East Groningen Waste Recycling Facility (OGAR). OGAR produces around 17,000 tonnes of compost each year from the VFG waste in the region.

Indaver was already 50% owner of the company in Oude Pekela, thanks to the takeover of Grontmij BRP in 2019. Over the course of 2022, we reached an agreement about purchasing the remaining stake in VFG waste. This takeover allows us to further strengthen our market position on residual organic waste in the northern Netherlands.

Indaver now has 10 VFG and green composting plants in the Netherlands.

The 10 sites work continuously to improve quality. Through mutual knowledge sharing, among other things,

At the end of 2022, Indaver in the Netherlands handed over the Koegors waste transfer station in Terneuzen to the Zeeuwse ReinigingsDienst (ZRD).

The ZRD was already using this site. We ensured there was a ‘warm’ transfer for the staff.

Controlled growth

Takeover Solvent Recycling In 2022, Indaver strengthened its position in the UK by taking over BIP Chemical Holdings, a solvent recycling company. The customers are the chemical and pharmaceutical industries.

The Indaver Solvent Recycling facility can process 30,000 tonnes of liquid waste streams from the chemical and pharmaceutical industry. After distillation and treatment, Indaver supplies fine chemicals back to these industries. The facility has a research laboratory and its own engineering and maintenance department. We have retained all staff primarily chemical engineers, process engineers and senior operators.

Storage and transfer There is also a transfer station and a tank park on the site. The transfer station permit allows for the storage of 30,000 tonnes of packaged hazardous waste prior to treatment. In the tank park we can store 2,800 m3 of liquid waste. Both have sufficient capacity to meet our customers’ needs.

European network The acquisition fits in perfectly with our policy to create maximum value from waste streams and to bring valuable raw materials back into the chain. As with our other activities, the new facility contributes to closing the materials loop.

Following the commissioning of Inda-MP, the facility in Antwerp (Belgium) with which Indaver will recover liquid waste streams from precious metals, this is the next step in the expansion of a network of solvent-management facilities in Europe.

INVESTING IN FURTHER SUSTAINABILITY

Belgium Sustainable Sludge Valorisation

The solvent-recovery facility has great future potential. Indaver is fully investing to improve the facility further, to increase efficiency and to guarantee business continuity. We have mapped out a long-term vision for increasing sustainability, such as generating energy from the incineration of low-quality solvents.

FOSTER is the name of the new facility for sustainable sludge valorisation that Indaver is developing with its partner, BESIX. Both partners will construct, finance and maintain the facility. This is being done on behalf of the water purification company Aquafin, on the site of the steel producer ArcelorMittal.

FOSTER is expected to be operational in 2026. The energy that this facility recovers will be supplied directly to the steel company in the form of steam. The process technology is focused on monosludge incineration, (also see p. 77).

We ensure that the safety standards we set on all our sites will also be guaranteed here. We get support from external parties on the risk assessments and the ATEX regulations. It goes without saying that we are also rolling out our Indaver safety-awareness campaigns on this new site.

United Kingdom New energy-from-waste plant In the south-east of England, at Rivenhall, Indaver is building an ultramodern energy-from-waste plant.

Among other things, Indaver is investing in a very efficient turbine that can recover even more energy from the same amount of waste. This is 595,000 tonnes of non-recyclable household and similar commercial waste each year.

The energy that is generated from the treatment of this waste will be supplied from the Energy-from-Waste facility to households in the surrounding area.

This makes the facility extremely sustainable and part of the transition to a circular economy (also see p. 76).

NESS-energy project In the autumn of 2022, the ‘cold commissioning’ of the waste-to-energy plant was carried out at NESS in Aberdeen (UK). Indaver will run this

facility for the next 20 years. Over this time, we will provide affordable, clean and locally generated energy. We generate this from around 150,000 tonnes of non-recyclable householdwaste that local authorities in the surrounding area supply each year.

The facility became fully operational over the course of 2023 (also see p. 71).

“Indaver looks at the circular impact of projects, but it isn’t just about circularity. The sustainability elements count too.”
