From linear to circular

The so-called ‘circular economy’ is providing opportunities to examine new concepts in our industry. Our definition of the circular economy consists of reusing, recycling and recovering water, resources and nutrients to create a more sustainable environment both at home and in the workplace.

Climate change The world is a rapidly changing place, not least due to the impact of climate change. Unless we act urgently to mitigate the effect of climate change, it will have a dramatic impact on our lives and the lives of our children and our childrens’ children. The historic Paris agreement on climate change not only set a path for 195 nations to keep temperature rises well below 2 degrees Celsius, but also introduced initiatives to combat climate change and promote investment in a low carbon, resilient and sustainable future. Climate change has already had a major impact in certain geographical regions around the world – we all need to work together to reduce the impact further over the coming decades.

A partner for our growing global customer base During 2016 we achieved some significant milestones and we are proud of our growing customer base across a broad band of sectors and industries. The increased focus on the Nijhuis Industries brand awareness is helping to embed our company profile in the minds of our customers as the company of choice for sustainable waste to value solutions.

We are equally excited about the increasing shift from ‘welfare’ to ‘well-being’ and from ‘ego’ to ‘eco’. These changes, especially in the developing world, promote the need for a more transparent solution and a more active contribution from the users of our innovative technologies and solutions. A new concept of ‘social innovation’ is becoming increasingly important in technical and process development.

The next industrial revolution The rate of change, for what we perceive to be solid business models, is accelerating. This is largely due to the rapid development of technology, in particular the use of the internet, smartphones, 3D printers and virtual reality. These developments are fueling the next industrial revolution. The question we need to ask is; how can we create opportunities for sustainable energy solutions where we for example enter into a 'partnership with the sun'? Can we learn from nature by designing our waste to value solutions in a way that mimics the natural world rather than causing it harm? We need to ensure that these are fundamental tenets of our business objectives.

Sustainable Development Goals To help create a context for our objectives, we can look to the United Nations to see what we can achieve together to transform our world. The Division for Sustainable Development (DSD), part of the United Nations, seeks to provide leadership and catalyse action in promoting and coordinating implementation of internationally agreed development goals. They have created a set of seventeen Sustainable Development Goals (SDGs) that focus on people, planet and prosperity.

At Nijhuis Industries, we can help to meet several of these important goals such as improving clean water and sanitation, implementing affordable and clean energy solutions and promoting initiatives for sustainable cities and communities. For example, the installations we have delivered in Ghana and Burkina Faso that treat waste and turn it into biogas, which is used for energy, are one of the examples of turning waste into value. Delivering an installation to reuse the water of the seal rescue centre in the Netherlands is another great example where animal welfare and sustainability objectives can be combined.

In the Netherlands for example, our contributions towards a sustainable environment also include being part of the Nutrient Ambition 2018 of the Dutch Nutrient platform. We are also an active member of the Netherlands Water Platform, co-organizing the Amsterdam International Water Week together with Aquatech, our involvement with the Dutch Poultry Centre and regional innovation hubs to succesfully develop sustainable solutions to convert biomass or manure into clean water and biodegrable fertilizers. These will all provide a platform which will help to contribute towards these goals.

What would you do to make the world a better place and what keeps you awake?

At Nijhuis we believe in anticipating the challenges within the industry and we recognize that cities for example, require smart and solid solutions in a world which is constantly changing. We call this a “fluid” world.

We have a lot to offer our customers and communities and we look forward to continuing our journey together to embrace the opportunities of the circular economy and create a more sustainable world. Nijhuis Industries, our business partners, other stakeholders and above all you, can make an impact on how we are going to shape our future!

By promoting best practice across our worldwide businesses, gained in more than 2400 references combined with continuous innovation and improvement, we can ensure that the wealth of knowledge that we have developed is used to our best advantage.

But besides solving your waste and water challenges, we are also keen to understand what ‘keeps you awake’ in order to make sure our research & development activities are responding to your immediate needs and requirements.

When it comes to success, it’s all about people and the relationships between our growing customer base, our team and our business partners are fundamental to our success.

I look forward to working with you all in 2017.

Towards a circular economy and sustainable world!

Kind regards, Menno M. Holterman, on behalf of the Nijhuis team Chief Executive Officer

REALIZING THE

CIRCULAR ECONOMY Page | 4

Kick-off Nutrients ambition 2018 by Dutch state secretary Dijksma On 5th October 2016, the Nutrient Platform had the kickoff of its action plan “Nutrients Ambition 2018” in The Hague, the Netherlands. The action plan is to formulate a number of goals that will contribute towards a circular economy and to scale up the market for recycled nutrients as soon as possible.

Secretary Sharon Dijksma led the ambition and gave the official launch by providing her signature. The government, the Ministry of Economic Affairs and the Ministry of Infrastructure and the Environment, together with 34 parties from the food industry, agriculture, water industry, fertilizer industry and waste are part of the Nutrient Platform. Geo Smith presented Nijhuis Industries and signed this ambitious plan.

The Secretary of State attended the kick-off, prior to the general debate in the Dutch parliament on the government programs “A circular Netherlands in 2050”. In this program, the action plan of the Nutrient Platform is playing an important role to contribute to a circular, future-proof and sustainable nutrient economy.

Nutrient recycling in Lombardy, Italy In light of this aspiration, the province of Lombardy in Italy has major challenges in the areas of air and water quality. The area has many similarities with parts of the Netherlands by the relatively high population density and intensive livestock farming. Both, the nitrogen emissions from livestock farming as the discharge of phosphorus and nitrogen from wastewater treatment are forcing the region to strive for short-term solutions.

For that reason, the province of Lombardy, together with the province of South-Holland, organised a workshop, on 13 and 14 October 2016, called "Nutrients in the circular economy" and undertook a plant visit. A delegation of 12 Dutch companies’ including Nijhuis Industries, Deltares, Wetsus, NuReCo, Valley Water Board Veluwe and the Nutrient Platform traveled to Milan to participate. The visit was accompanied by deputy of South-Holland Rik Janssen and Minister of Lombardy Claudia Terzi.

The Dutch delegation also visited a wastewater treatment plant and manure treatment plant, which proved again that there is a real need for innovations to recover and reuse nutrients.

During the following workshop this nutrient issue was also the main point for debate. Both Italian and Dutch parties gave their visions on nutrient recycling.

Nijhuis nutrient recycling solutions Wouter van Betuw, Strategic Sales Engineer at Nijhuis, presented the different Nijhuis solutions for nutrient recovery in manure and wastewater treatment.

Mineral Fertilizer treatment The wastewater plant at the Azomures mineral fertilizer factory, Romania, inaugurated in September 2016 treats 22.000 m3/day at the municipal sewage treatment works “Aquaserve” in Tirgu Mures. It includes a specific biological process, BIOCTOR-MELAMINE, to remove melamine and other forms of nitrogen and discharge the clean water into the Tirgu Mures river.

Manure treatment Nijhuis ‘GENIAAL’ is a total solution for the processing of manure and converts 1 m3 raw manure or digestate from anaerobic digestion to approx. 60-80% clean water and approx. 20-40% bio-based fertilizers on demand (phosphate, nitrogen and potassium fertilizer). GENIAAL is a cost effective, innovative and, above all, sustainable solution to the manure and phosphate surplus for large-scale manure processing companies with a scale of more than 50.000 tons of raw manure per year.

It is expected that this refining technology will play a key role to help farmers and manure processing facilities worldwide to treat manure in a sustainable way against the lowest possible cost and reduce their dependence on coventional fertilizer.

From Cost Center to PROFIT Center: Cedrob Phase II In December 2014, Nijhuis was awarded the contract to build another state-of-the-art wastewater and biogas plant for Cedrob S.A., designed with a view on sustainable water use and resource recovery. The installation is not only a WWTP. It is an example of turning the circular economy and profit center theories into reality.

Nijhuis designed, obtained all the necessary permits, built, produced, delivered and installed the complete installation in close consultation with Cedrob. In accordance with to the expectations of the customer, the new Nijhuis installation was ready to receive the wastewater from the new part of the poultry processing factory in June 2016.

As this important milestone was reached, installation works for the digesting and dewatering part started immediately. At the beginning of January 2017 the entire system was commissioned, aiming to achieve the required performance in biogas production and sludge quality.

Based on the professional cooperation between the terms and the results achieved, Cedrob has awarded the next and 3rd extension to Nijhuis already. This will be started immediately after the commissioning of phase 2 and will grow it’s capacity to more than 9000 m3 / day of processed wastewater.

About Cedrob Cedrob is a leader in meat processing and poultry production. The company has its own breeding farms, hatcheries, broiler breeding, poultry slaughterhouses and processing plants in Poland. Cedrob strives to become energy-self-sufficient. Next to operating three slaughterhouses with a total capacity of 150.000.000 broilers and 900.000 geese per year, they are also hatching 160.000.000 eggs, and producing 720.000 tons of fodder per year.

Phase 2 of the Cedrob plant was extremely complex. Nijhuis had the challenging task to develop the installation on the available small plot of land and keep the existing WWTP up and running. The valued cooperation between Cedrob and Nijhuis teams allowed the project to run smoothly and with the desired outcome.

Cedrob has chosen Nijhuis again because of our application knowledge and the trust and confidence built over years between both teams.

Nijhuis delivered and installed a very flexible system to treat more than 5000 m3 per day, consisting of a new filter system (NRF 90/300), sludge dewatering, flocculation-flotation system (PFR 140/IPF 180), a double continuous aerobic biotreatment (BIOCTOR) with activated sludge flotation (GDF 40), digester (AECOMIXTM-TAURUS) and digestate dewatering.

Reducing chemicals with i-DOSE Since its introduction at Aquatech 2015, i-DOSE has been drawing a lot of attention from the market. Today, the intelligent dosing system i-DOSE is part of the Nijhuis total solution and serve the purpose of changing the way traditional chemical dosing systems work.

In the USA, a protein processing plant in Minnesota has chosen Nijhuis to supply the new wastewater primary treatment system, as part of their new pork processing plant. As part of the primary treatment system, Nijhuis proposed an i-DOSE system because the customer wanted to reduce onsite operating time and chemical costs for wastewater treatment operations. Also, the ability to include i-DOSE reduced the volume of the required EQ tank, which was also important due to site space constraints.

Nijhuis i-DOSE finalist WIS Award The Nijhuis i-DOSE is proudly nominated for this years WIS award. The Dutch Water Alliance challenges innovative entrepreneurs to nominate their most innovative product for the prestigious WIS-Award 2017. This award helps companies get new and innovative products in the water technology spotlights. The winner will be announced during the final at the WaterLink symposium at the 26th of January 2017.

The second largest hatchery plant in Russia, Roskar also has its own slaughter line. Here i-DOSE takes an important role in optimal chemical dosing. The drive for the customer to choose i-DOSE emphasized that a reduced level of human intervention is highly desirable, considering there is a large distance between the production plant and WWTP. Thanks to the i-DOSE, they will significantly reduce the frequent visits to the WWTP to adjust the chemical dosing.

Eliminate micropollutants with ozone

Nijhuis ozone solution is being tested at pharmaceutical wastewater treatment plant

Micropollutants often enter the environment through municipal and industrial wastewater, as most treatment facilities are currently not equipped with a fourth cleaning stage, e.g. ozone or activated carbon. For micropollutants, there are no discharge limits for wastewater treatment or drinking water treatment since their presence was discovered relatively late because of insufficient knowledge of the effect or damage to the environment.

Ozone research project

Existing WWTP for 40.000 inhabitants

Micropollutants elimination with ozone or activated carbon

The wastewater treatment plant at Boehringer in Biberach an der Riß is designed for approx. 40.000 inhabitants, which corresponds to a wastewater quantity of 2,000 m³ / day. The biological purification is consisting of a SBR process, where approx. 360 m³ / day is discharged to the test facility. Approximately 40 different micropollutants are added in appropriate quantities to test the plant.

The wastewater containing the micropollutants is firstly treated with ozone. The ozone has 20 minutes to oxidize with the wastewater in the reactor. During the oxidation process of the micropollutants, metabolites (intermediate products) are formed, which are adsorbed by a granulated activated carbon filter. After the treatment, the process water is returned to the effluent treatment plant and discharged into the river.

Phosphorus Removal with Tertiary DAF and i-DOSE In 2016 Nijhuis secured the contract for the delivery of a containerized Tertiary DAF system incorporating i-DOSE to remove phosphorus at a municipal WWTP near Manchester. The system is designed to reduce total phosphorus to levels as low as 0.1mg/l in order to help meet increasingly stringent discharge standards being introduced by the Water Framework Directive.

This system forms part of a trial within the UK where a number of different technologies are being tested to assess their performance over a 12 month period. The system was commissioned in December 2016 and will also be supported during the testing period using the NI-connect system to remotely access the system and i-MONITORING to ensure the system achieves its maximum performance.

High phosphorus levels in surface waters can lead to Eutrophication where there are too many nutrients in the water which stimulates plant growth, such as algae. When this process takes place too quickly it can be harmful to aquatic life and causes further problems in river/lake water quality.

Boehringer Ingelheim Pharma GmbH in Biberach an der Riß has started a research project in cooperation with the Ingenieurbüro Dr. Jedele, reducing micropollutants to the environment. Over a period of 1.5 years, they will investigated ways in which micropollutants oxides with ozone and is adsorbed with activated granulated carbon. The project is financed by the State of Baden-Württemberg. Nijhuis commissioned a modular ozone system for 100g O3/h, in March 2016, which was installed by the customer in a container.

ASPECTS TO SELECT AERATION PRODUCTS

"The product design and chosen materials are focussed on durability, long operational life and energy efficiency.�

Nijhuis Industries NEWS I www.nijhuisindustries.com

| NIJHUIS APPLICATION KNOWLEDGE

Aerobic treatment systems are based on a biological process operated and controlled under aerobic conditions (with aeration) that effectively treats COD, BOD and VSS into water, carbon dioxide and new biomass. Besides the applied (waste)water SBR, Continuous, MBR and MBBR biological technologies, the market of aeration products, part of the biological technologies can be divided into surface aeration products and bottom aeration products.

Diversity and comparison An important part of selecting biological technologies is diversity and comparison between several surface and bottom aeration technologies and products. By properly selecting, designing, building and operating aerobic processes, customers can achieve the best aerobic treatment solution that is sustainable and has the lowest possible cost of ownership.

By selecting the right type of aeration product, the following aspects need to be considered:

(Waste)water aerobic technologies

1.

2.

What kind of aerobic technologies can be applied to treat the amount of wastewater and/or does the customer already prefer a technology? (such as SBR, Continuous, MBR and MBBR biological technologies).

Plant design and footprint

How much space does the customer have to install the aerobic solutions and aerobic product?

4.

Tank design and mixture

5.

Maintenance / durability

6.

7.

Does the climate have an impact on the type of aeration products?

Does the tank design have an impact on the type of aeration product and wastewater mixture?

Does the customer have the resources to maintain the aeration product sufficiently?

The produced product and chosen raw materials are selected on durability, long operational life time and energy efficiency. The installation of these products ranges from small tanks to lagoons due to the difference in mixing and oxygen dispersion.

Our objective is to design the most flexible and competitive solution combined with a broad range of aeration technologies securing the best solution for each application. Therefore Nijhuis has included their FLEX-AERATION product range into their Sustainable Water Use & Resource Recovery portfolio, consisting of several surface and bottom aeration technologies.

Surface aeration solutions Surface aeration solutions (NFA-S) can be applied with high or low speed aerators. They have high oxygen transfer possibilities and excellent mixing without affecting the sedimentation process of the sludge during the sludge water separation, for example in a clarifier. Generally speaking, for maintenance purposes the surface aerator can easily be removed.

Bottom aeration solutions Bottom aeration solutions (NFA-B) can be divided into tubes or disc diffusers. The piping and the bodies of the diffusers are made of environmentally friendly polypropylene and can easily be recycled at the end of the lifetime. The frameless design of the diffuser body provides maximum aeration-active membrane surface. The aeration affected is uniform over the surface of the membrane.

Energy

Does the operational cost of energy play a role in the decision making process for the customer?

Cost

Does the customer have the budget to buy this type of aeration product?

Nijhuis FLEX-AERATION bottom (NFA-B): Environmental friendly, sustainable and durable product

SUSTAINABLE disinfection of cooling water WITHOUT CHEMICALS To prevent bacteria growth and legionella outbreaks in cooling towers, chemicals can be added to disinfect cooling water. However, disinfection with hazardous chemicals is not sustainable. Therefore the Radboud University Medical Centre (umc) in Nijmegen amongst others has chosen for cooling water management with ozone, "It's energy efficient, no chemicals are used, safer, and the blowdown water quantity is reduced”, said maintenance manager Perry Janssen from Radboudumc.

Follow the principles of the circular economy The sustainable management of cooling water is in line with the sustainability policy of Radboudumc for waste, energy, procurement and construction. The medical center follows the principles of the circular economy as a starting point for sustainable business. Water management with ozone saves a lot of intake water compared to traditional disinfection with chemicals, maximizing the profit of this disinfection method.

The cooling water system is continuously monitored by Nijhuis i-Monitoring and samples are taken every month by an approved body.

An advanced remote system reads the installation and Janssen asks his mechanics every week to inspect the systems.

Ozone disinfection of cooling water systems, safer and more sustainable “As a university medical centre we want to be progressive in the field of cooling water management”, said Jansen, the reason why Radboudumc switched from chemical disinfection to ozone for more than 10 years ago. “With a decent ozone concentration and flow there is no chance of biological activity and the passivating effect ensures that the wall thickness of the tube bundle will be unaffected[begrijp deze laatste statement niet!]”, says Marcel Oonk, operational director of Nijhuis Ozone Solutions. Janssen can also proof this statement with their own research.

Additionally, blowdown water quantity will be reduced and no hazardous chemicals need to be stored and carried around by employees. Because no chemicals will be added into the discharged water, there will be also huge savings on regional water authority’s costs. "We are now investigating if we can reuse the blowdown water," says Janssen.

Six Nijhuis ozone installations The cooling water will be used for, for example, air handling systems, MRIs and CT scanners. Six Nijhuis ozone installations are installed at approximately one square kilometre of land. In winter, when the ambient temperature drops down, some cooling water systems can be turned off and during hot days the hospital has additional capacity to use all the cooling towers.

Nijhuis Industries NEWS I www.nijhuisindustries.com

| INDUSTRIAL SUCCESS STORIES

"The medical center follows the principles of the circular economy as a starting point for sustainable business” Use the natural power of water "With ozone, you use the natural power of water," said Oonk. Ozone (O3) is generated from oxygen and it breaks organic bacteria very efficiently and then goes back to harmless oxygen (O2). Ozone prevents bacteria growth and legionella outbreaks and creates an alkaline environment (pH> 8.5) where corrosion has no chance.

Ozone is therefore the most sustainable solution for cooling towers, but can also be applied in other water reuse applications, such as the dairy industry for the treatment of water of the evaporation of milk. In addition, ozone is also used as oxidation power to break down medical residues to ensure the environment is not affected.

Legionella is a serious threat. Approximately around thousand people a year die in the Netherlands because of the legionella disease. Especially people with a reduced immunity are at risk. Therefore, the government in the Netherlands has set high demands for the use of open cooling towers to prevent against legionella outbreaks. Organizations that fail and do not meet the demands can be punished with heavy fines.

Explantation Legionella according “Centers for Disease Control and Preventation" Legionellosis (LEE-juh-nuh-low-sis) is a respiratory disease caused by Legionella bacteria. Sometimes the bacteria cause a serious type of pneumonia (lung infection) called Legionnaires' disease. The bacteria can also cause a less serious infection called Pontiac fever that has symptoms similar to a mild case of the flu.

"Nijhuis provides a total water management concept.”

Nijhuis Industries and Azomures S.A. officially inaugurated one of the largest and most advanced WWTP's ever built in Romania On 20 September 2016, Nijhuis Industries and Azomures S.A. officially inaugurated a state-of-the-art Romanian WWTP. The WWTP treats 22.000 m3 wastewater per day, containing high nitrogen values and has the latest incorporated controls to manage and monitor the system, as part of their expansion program.

A WWTP with the lowest possible OPEX

Azomures S.A. decided in 2014 to build a new biological WWTP to prepare for new 2016 regulations of discharging effluent into the Tîrgu Mures river. The total project, which is one of the largest and most advanced plants ever built in Romania, complies with Romanian and European environmental and productivity standards.

Here the wastewater is collected in two parallel biological systems consisting of pre- and post-denitrification tanks, aeration tanks and clarifier systems.

Inauguration program The inauguration program included a presentation by senior executives of Nijhuis Industries, Azomures and Aquaserv (operator WW of the municipality of Tîrgu Mures). The program was followed by an introduction tour around the state-of-the-art wastewater treatment plant.

The official ribbon-cutting ceremony took place at the Azomures WWTP together with Mr. Lucian Goga, Prefect of the Mures County which is part of the historical Transylvania region. The Prefect takes a lead-role in the implementation of the Romanian water and wastewater regulations and compliance to the EU regulations.

In July 2014, Nijhuis Industries won the contract to deliver a large turnkey wastewater treatment project for Azomures. As a turnkey contractor, Nijhuis designed a system with a pumping station to transfer the water 4.5 kilometers from the Azomures plant to the Tîrgu Mures municipal plant site (Aquaserv).

Nijhuis BIOCTOR-MELAMINE The Nijhuis BIOCTOR-MELAMINE solution is a specially designed biological treatment plant, to treat melamine and other nitrogen containing components, which need to be removed from the wastewater to meet the Romanian and European effluent requirements.

Specifically adopted seeding sludge was introduced to achieve optimal growth and adaptation of the bacteria in the biological system. The WWTP was commissioned mid November 2015 and since then over 5.500.000 m3 of wastewater has been treated and discharged to the Mures river.

Since 1 January 2016 the values are monitored daily by the Aquaserv WWTP operators and the Nijhuis monitoring team.

Nijhuis team releases three rehabilitated seals In September 2016, the Nijhuis team visited the Seal Rescue and Rehabilitation Center (SRRC) Pieterburen and released three rehabilitated seals. Five years ago, the Nijhuis water reuse installation was installed at the center. Previously, fresh water was needed to prevent the pollution in the pools because the existing treatment didn’t work sufficiently.

Water reuse installation As a solution to prevent quickly polluted pools, Nijhuis provided a water reuse installation which ensures huge water savings and clean effluent which meets the customers sustainable requirements.

The Nijhuis Staff Association supports the good work of the seal center and therefore they have adopted the three seals. The adopted seals “Hilkia”, “Spetter” and “Lucky “were released back into the Dutch Wadden Sea. At the seal center, the dedicated staff of the Pieterburen center explained how the Nijhuis installation works and how the seals are rehabilitated. The Nijhuis installation is continuously in operation in order to ensure a good water quality and is consisting of two filters (NDF), Flocculator-DAF (PFR and IPF), effluent polishing (CarboPure) and a disinfection step.

The water in the pools has a constantly clear quality which is a huge advantage for the seals and for the team members of the center that visually monitor the condition of the seals. This type of installation is another succesfull example that Nijhuis supplies smart customized installations in combination with their application knowledge which meets the requirements of the environment and customers.

Early in the morning, the Nijhuis team left by bus to be on time at “Lauwersoog” in the North of the Netherlands. A ship brought the team to the “Engelsmanplaat” for a short walk before visiting the seal center. On board were three young seals which were rehabilitated by the center and were looking forward to enjoy their freedom.

"We thank the seal center for their hospitality during this beautiful day and very special moment!”
