his is a great time to be involved in the anaerobic digestion (AD) and bioresources sector. The quality and quantity of feedstock on the market is set to increase, and the size of the prize will continue to grow, with the appropriate support from government. Across Europe, plans to maximise the economic and environmental benefits from bioresources are coming increasingly to the fore, and the EU Circular Economy Package, although not as ambitious as it could be, is driving investment. This, along with the right financial and regulatory incentives, will see the expansion of AD continue. The sector now needs to meet or match these commitments to provide the necessary infrastructure. This will require an expansion of existing facilities, as well as the development of new plants of various sizes. The recent Industrial Strategy provides a mechanism for supporting smaller scale, single (or limited) biowaste stream on-site facilities, if the right incentives are configured. Policy makers must also support the sector by creating the appropriate market signals, given that AD is the best option for the recovery of biowaste. Generally viewed through the prism of energy generation, going forward we must focus on the value biowaste can provide above and beyond being an electricity source. While there has been considerable progress to improve the quality of digestate, further market intervention is required. Moreover, the use of biogas for transport will continue to prove important – but perhaps the biggest opportunity lies in harnessing its use in the gas grid. Correct incentives on how to use these resources are important, but we also must focus on how to get more feedstock to AD facilities. In this respect, Scotland is leading the way. A total of 1.6m Scottish households, around 80 per cent, now have access to separate food waste collection and since 2016 all businesses which produce 5kg or more are now required to present food waste separately. Furthermore, a landfill ban on municipal biodegradable waste from 2021 will mean that around 1m tonnes of feedstock will enter the market. That is the size of the prize in Scotland and together, across the UK and beyond, it’s time to design and deliver the system that will capture all the benefits of biowaste.

New government, new opportunities


By Charlotte Morton, ADBA’s Chief Executive

y the time you read this we will have a new government in Westminster, the third in just over two years. Whatever your view on the merits or otherwise of Theresa May’s decision to call a snap election, we can at least be fairly confident of some degree of political stability for the next two or three years while negotiations on the future of the UK’s relationship with the European Union take place. So what does a new government mean for AD? During the election campaign, we called for the value of AD to be recognised in all political parties’ manifestos and put forward the following key asks: • The legislation on the Renewable Heat Incentive (RHI) should be reintroduced as soon as possible in the next parliament with an increased budget for the RHI so we can continue to produce clean, green energy and useful products like biofertiliser; • Mandatory separate food waste collections should be introduced in England to divert waste away from landfill and help to meet our carbon commitments; • UK farmers should be supported through the restoration of viable tariffs to the Feed-in Tariff (FIT) scheme with the AD capacity cap being removed. It’s likely to be a while before we get clarity on the extent to which the new government will support these requests, but we’ll work hard to ensure they become a reality. With so much focus on the general election, it’s important not to overlook the eight new regional mayors who were elected in early May. With increasing devolution across the UK, the importance of promoting AD at regional and local levels is only growing stronger. We wrote to each of the new mayors straight after their election to highlight to them the important role of AD in supporting local economies and helping to reduce and recycle the huge amount of food we waste, providing the springboard for further engagement as they settle into their new jobs. Amid all this political change it’s also important to stay focused on where AD can make a significant contribution to meeting UK policy goals. We’ll be pushing BEIS to incorporate AD as part of bespoke sector deals for agri-tech

and the bioeconomy, and within the Clean Growth Plan. An opportunity has also presented itself in the publication of the government’s long overdue plan and consultation on improving air quality in our towns and cities. Compared to diesel, biomethane as a transport fuel offers lower NOx and particulate matter levels whilst also reducing CO2 emissions, critical for decarbonising transport. We will be making clear the benefits of biomethane in decarbonising transport and improving air quality in our response to Defra’s consultation. Politics and policy will be a key theme of July’s UK AD & Biogas trade show, which this year will be bigger and better than ever through its new partnership with the World Biogas Expo 2017. The theme of this year’s combined event will be demonstrating the significant contribution biogas makes to meeting the UN Sustainable Development Goals, and the actions we need to take to ensure that every country, including the UK, develops policies to enable our industry to deliver that huge, much-needed contribution in time. 2030 is less than 13 years away! In addition to seeing all the latest technologies and innovations, it will be the perfect place for us all as an industry to come together to find the space in the ever-changing political landscape to make clear the many benefits of AD. I look forward to seeing you there and discussing how we turn this period of political change into a huge opportunity to grow the industry and protect our future.

Food Waste Report published With the announcement of the unexpected election campaign, the Environment, Food and Rural Affairs Committee published its long-awaited report into food waste collections in England. We have joined the Committee in calling food waste levels in England a ‘scandal’ and described the Committee’s final report into the costs of food waste in England as a ‘wake-up call' for the next government.

We are also calling on all political parties to address the urgent problem of food waste and commit to introducing mandatory food waste collections in England, as all the devolved governments have already done.

The report examines what Committee Chair Neil Parish has called the ‘grotesque economic, environmental and social costs’ of food waste in England, estimated at over £10bn a year, excluding disposal costs to local authorities. The report makes a series of recommendations on how food waste levels could be reduced and explicitly recognises the role that AD plays in recycling inedible food waste into low carbon heat and power, green transport fuel, and organic biofertiliser. The report states that AD is the best treatment option for food waste that cannot be avoided or redistributed for human or animal consumption.

ADBA News ADBA calls for AD to be recognised by new government With a new government on the horizon, we are calling for the value of AD to be recognised in the new administration’s legislative programme. Commenting, our Chief Executive Charlotte Morton stated: “The performance of local authorities and politicians on the ground can have an impact on how people vote nationally. There are levers that government can pull to make their job on the ground easier, and this is true when it comes to supporting the AD industry and sorting the problem of food waste collections in England.” In order to lock in the progress that our innovative industry has made over the last few years, we are calling for three policies that all parties should implement: • Re-introduce the legislation on the Renewable Heat Incentive (RHI) as soon as possible in the next parliament, and commit to increasing the RHI budget so we can continue to produce clean, green energy and useful products like biofertiliser. • Commit to legislation introducing separate food waste collections in England, to divert waste away from landfill, helping meet our carbon commitments. • Support UK farmers by restoring viable tariffs to the Feed-in Tariff (FIT) scheme and removing the AD capacity cap.

We will be taking these messages to the new government and helping our members lobby their new MPs over the coming weeks. For more information, contact our External Affairs Manager, Jon Harrison:

ADBA congratulates local election and mayoral winners ADBA warmly congratulated all successful mayoral candidates and councillors elected in May’s local and mayoral elections. As the winners turn to their new responsibilities, we will be highlighting to them the important role of AD in supporting local economies and helping to solve the problem of food waste. As our members know, AD is an environmentally friendly, cost-effective solution to dealing with much of what we think of as ‘waste’. Instead of burning it, or sending it to landfill, AD plants could potentially turn that waste into 30 per cent of the UK’s household gas or electricity demand. This means less waste to landfill, stable energy prices, and fewer carbon dioxide emissions – creating 35,000 potential jobs, too.

material intended to be burned or sent to landfill is lowered, and can instead be used to produce clean, green local energy. We will also be working to put members in touch with elected representatives so they can see first hand how AD can help boost the UK economy.

ADBA members are helping MPs to see first hand the benefits of AD – here, Liz Truss MP visits the Future Biogas Methwold site

And it is not just in the UK that AD can have a positive impact. The potential global AD market is estimated to be worth £1 trillion – a market the UK is in an excellent position to contribute to and benefit from, and which would also help towards achieving our aims under the UN’s Sustainable Development Goals. We estimate that the potential export value of UK AD technology is over £2bn per year. We look forward to working with the new councillors and mayors. In particular, we will be encouraging local authorities to comply with the food waste hierarchy, ensuring that the amount of recyclable

Energy generation from AD continues to climb AD currently produces approximately 10.7 TWh of biogas in the UK, equating to 2.2 per cent of the total 477 TWh of UK gas production in 2016. This is up from 9 TWh in 2015. The energy is generated from 554 AD plants across the sewage, agricultural, municipal/ commercial and industrial sectors. 3.5 TWh of this comes from biomethane production which is injected into the gas grid, up from 2.6 TWh last year. AD operators are finding it increasingly attractive to upgrade their biogas to biomethane and export it to the grid, thanks to greater government support offered through the RHI scheme due to the lack of progress to date on decarbonising heat. The remaining 7.2 TWh of biogas is used to produce 2.8 TWh of electricity (this assumes 39 per cent electrical efficiency on average for CHP engines). While the remaining 4.4 TWh is mainly vented, there are now more operators who are finding a productive use for this thermal energy to heat their own operations, such as farms, greenhouses, or nearby factories.

Hugh Vaughan – a tribute The AD community has paid tribute to Hugh Vaughan, UK Director of pump and mixer manufacturer Landia who, together with his wife Liz, tragically passed away after a road accident whilst on holiday in Mauritius. Known for his honest, straight-talking approach, Hugh had been at Landia UK since its formation in 1994. The company was a founder member of ADBA and Hugh one of the association’s founder directors. “Hugh contributed so much to ADBA and was a fierce advocate of the UK AD industry, helping to grow the sector to what it is today,” said Charlotte Morton, ADBA’s Chief Executive. “He was hugely instrumental in the launch of our first trade show and conference, and even when he was no longer an ADBA Director, Hugh continued to lobby for the industry and support the association from behind the scenes. Hugh will be sorely missed and we send our heartfelt sympathies to Hugh and Liz’s families, and to Hugh’s work colleagues. We have lost a true friend.” Liz Robinson, who had worked alongside Hugh since 1994, takes temporary charge at Landia UK together with Sales Manager Paul Davies, who has been with the company since 2002.

Best Practice Matters Best Practice Scheme to be piloted this summer As we near our next big milestone for the Best Practice Scheme – the launch of the pilot certification scheme – we would like to say a huge thank you to all those who have supported this project. The scheme development has been shaped by operators, developers, professional organisations, regulators and representatives from the insurance sector, and this is much appreciated.

For information and advice on any areas relating to AD best practice, contact our Environment and Regulation Manager, Jess Allan T +44 (0)203 735 8380 E @JessicaAllan2 The project aims to help operators achieve high standards of environmental protection, health and safety, and operational performance, and to gain recognition for doing so. The certification process will involve AD operators applying to the scheme, undergoing an assessment against the scheme criteria and, if successful, having their plant certified as meeting best practice as defined by the scheme. We are working with a small number of operators, representing a range of plant sizes and feedstock types, to pilot the scheme from July 2017. This will allow us to test it and identify any improvements that we can make, and there will continue to be a need for input from industry stakeholders throughout this process. All being well, we are aiming to officially launch the scheme at the end of the year. It is important to reiterate that participation will be voluntary, but we believe there is a compelling business case for AD operators to get involved. We are working hard with our contacts in the insurance sector and at the regulatory bodies to ensure that operators who do participate in the scheme will see real benefits; for example, lower regulatory fees and reduced cost of insuring their plant. When we officially launch the scheme later in the year we will set out in more detail the benefits that operators may experience. Don’t forget that our Best Practice Checklists are free to download from our website and are there to guide you on procurement, risk management and operational performance. Whether you have an operational plant or are developing a project, please take advantage of these free guides, available from

News from Scotland Employment rises in Scotland’s renewables sector Employment in Scotland’s low carbon and renewables sector increased by more than a third in 2015. The sector generated a turnover of £10.5bn in 2015, according to figures released by the Office of National Statistics, while the number of employees rose from 43,500 in 2014 to 58,500 in 2015. Paul Wheelhouse, Minister for Business, Innovation and Energy, said: “These are impressive figures that show how the Scottish Government’s focus on decarbonising our energy system has not only allowed us to meet our climate change obligations, and to have done so early, but it has also significantly boosted the Scottish economy.”

New SEPA guidance on food waste management and digestate SEPA has published new guidance on Food Waste Management in Scotland, which sets out obligations along the chain of food waste management to achieve high quality recycling. The chain of management includes the waste producer, collection service provider, food waste treatment facility and final user of the food waste-derived digestate.

Scottish Renewables CEO to step down Scottish Renewables’ Chief Executive, Niall Stuart, is to step down in August. Niall, who has been in the position since September 2009, said: “I have greatly enjoyed my time with Scottish Renewables, and it is clear that we have all achieved a huge amount over the last seven years. We have grown our sector to become the country’s main source of electricity – more than doubling capacity since 2009 – and recently secured government support for a new renewable energy target for 2030.” Mr Stuart’s replacement has not yet been announced.

SEPA has also revised its position for the Regulation of Outputs from Composting and Anaerobic Digestion Processes. These revisions set out limits (by weight) of physical contaminants (including plastic) to 50 per cent of those specified in PAS 100 (compost) and eight per cent of those specified in PAS 110 (digestate) by 1 Dec 2019. This will align SEPA physical contamination limits with Quality Meat Scotland (QMS) standards. Both the guidance and amendments support the Scottish Government Strategy for a Circular Economy, and the SEPA Waste to Resources Framework.

Operator & Working Groups Activities step up for influential groups It’s been a busy few months for our operator and working groups. Since our last issue, four groups have held meetings, details of which are listed below. As well as these, we also host two further groups – the Biomethane to Transport Operators Group and the Food Waste Operators Group – giving us coverage over a wide range of AD business areas.

Meeting round-up

Our Biomethane to Grid Working Group discussed the forthcoming Renewable Heat Incentive implementation and what the uptake to the scheme might be once tariff guarantees are launched. Some members feared that tariff guarantees would be easier for larger projects or those in less need of external financing.

We held a short conference call with members of our Water Sector Working Group, to update them on the implementation of Ofwat’s Water 2020 Framework and sludge management. We then helped the Chartered Institute of Water and Environmental Management (CIWEM) organise a larger workshop on the potential for co-digestion of sludge with non-sludge feedstocks, which ADBA will be working with others to take forward. The top two items on the agenda for the most recent meeting of our Training and Safety Working Group were odour and training, with members agreeing to review the training available to the industry and how it can be improved. The group is also setting up a sub-committee on odour management, which wider ADBA members are welcome to join. Finally, members of our Agricultural Operators Group discussed forthcoming changes to the financial incentives, crop rotations and a Department for Business, Energy and Industrial Strategy (BEIS) research project on methane leakage. Our agricultural operators are probably our most outspoken members so this was, as ever, a lively affair.

Reaching our potential

Taking the UK AD industry to the top


naerobic digestion offers a wide range of benefits to the UK economy: it generates green heat and power, supports farmers, maximises the value in our waste, cuts our carbon emissions, provides low carbon transport fuel, helps to restore soils, replaces fossil fertiliser, creates jobs and provides an excellent export opportunity for British firms.

time if all policy decisions and investment in research was supportive of AD,” explains ADBA’s Head of Policy, Ollie More. “But reaching that figure will not only require government support; it will also take a huge effort on the part of the AD industry.” So just what needs to happen next to turn this potential into a reality?

Yet while the UK AD industry has continued to grow in the face of challenging market conditions, we are still some way off from reaching our full potential. Current energy generation from AD is around 10 TWh per year, but ADBA’s research suggests that renewable gas could actually produce as much as 55 TWh of methane by 2032. If AD is combined with the biomethanation of renewable hydrogen (see article on p35 of issue 35), then this figure could reach 77 TWh. “The 77 TWh ‘high’ estimate would be our aim for 15 years’

Current AD deployment

Additional support for the use of manures, plus a new UK farm policy to support AD, is required to ensure the industry has sufficient feedstocks going forward

There are currently 554 operational AD plants in the UK, with a total installed capacity of 711 MWe-equivalent. The majority of these are electricity CHP plants, but biomethane production is becoming more important and currently represents almost a third of the total capacity. Recent plant openings have demonstrated the versatility of our industry – from AD4Energy's 165 kW plant in Cambridgeshire, which processes crops, to Greener For Life’s 500 kW Tiverton-based facility, which treats a mix of agricultural waste and crops; to Amur’s 800m3 gas to grid plant in South Milford, which treats food waste (pictured above). In addition to the 554 existing plants, a further 440 projects are in planning (either having submitted a planning application or having had their application approved). If all of these were to be constructed, it would add a further 497 MWe-equivalent to the UK’s installed anaerobic digestion capacity. However, with agricultural and food processing wastes, together with energy crops, forming the majority of feedstock for new plants, there is a fear that there will be insufficient inputs to sustain the levels of expansion we hope to see. If the UK biogas industry is to reach its full potential then a whole host of factors need to come together, including energy and waste policy, new technologies to maximise plant efficiency and enable the use of novel feedstocks, as well as support through

project finance and the planning system. There is no ‘silver bullet’ which can deliver the necessary step change in project deployment and plant output. Every section of our industry will need to play its part in helping us reach our overall potential.

The need for stable political support

Long term policies driven by sound science and economic objectives are needed for any industry to flourish. To say that policy certainty has been lacking in the UK’s approach to renewables may be an understatement, but the many changes to support over the last 10 years have at least demonstrated how resilient our sector is. “The AD industry works to longer timeframes than government realises,” points out Ollie More. “If we want new entrants to the market, which could help improve competition, then government needs to provide a long term framework. Who wants to enter a market that only has visibility up to 2020? A clear statement from government saying that it wants to support green gas and sees a role for new projects being built up to at least 2025 would be hugely welcome.” Ollie also points out that closing the Feed-in Tariff (FIT) scheme to new entrants will dramatically reduce deployment. “Without another look at the FIT policy, the days of building 100 AD plants per year, as we had in 2014 and 2015, will be gone,” he states. “At the current rate of applications to the FIT, it could be

closed to new applicants by as early as 2018.” On the other hand, once new legislation comes into force, the tariff for biomethane injection up to 40 GWh per year will be raised above five pence per kWh once more, while the Department for Transport is doubling the target for renewable transport under the RTFO. DfT is also introducing a sub-target for the use of ‘development’ fuels, which ADBA is arguing should include biomethane.

Better access to feedstocks

Legislation will also be needed to support an increase in the use of food waste and other waste materials as AD feedstocks. “We need separate food waste collections across the whole of Britain – England currently lags behind the rest of the UK in this respect,” explains Ollie. “We also need additional support for the use of manures, particularly at the small scale level. We need either the FIT to be reformed and to continue to be more supportive, or failing that a new UK farm policy to support AD. And we need a continued RHI or equivalent scheme offering the right level of support – the risk of degression is always hanging over the industry.” Using anaerobic digestion as the preferred treatment option for food and other wastes would not only allow the sector to grow, it would deliver other environmental benefits to society. “AD currently recycles around 2.4m tonnes of the 10m tonnes of post-gate food and drink waste produced annually in the UK. Our calculations suggest that AD could actually recycle over 6m tonnes if all unavoidable and inedible food waste was made available as feedstock,” points out Chris Noyce, ADBA’s PR & Parliamentary Affairs Manager. “Effective enforcement of the waste hierarchy would ensure, for example, that all unavoidable food waste not suitable for redistribution to people or animals would be sent for recycling through AD rather than being sent for incineration or, even worse from an environmental perspective, to landfill,” continues Chris. “The UK AD industry would be in a strong position to treat this food waste were more of it to become available.” What’s more, diverting all the biodegradable municipal waste which is currently sent to landfill in England to AD would deliver emissions reductions of more than nine metric tonnes of carbon dioxide equivalent per year, the figure required to meet the fifth carbon budget reduction target. This has led the Committee on Climate Change to specifically identify AD as vital to the country meeting its carbon targets. In addition, the

Reaching our potential of feedstock but it could also allow the creation of wildlife corridors along our road networks; if managed correctly, verges can provide vital habitat for wildflowers and the wildlife that depends on them.

Improving plant performance

However, if biogas is to generate anything like 77 TWh of energy each year then the issues of plant performance and digester efficiency also need to be addressed. Across the industry as a whole, the average annual load factors rose to a record 73 per cent last year, up from 69 per cent in 2015, and just 46 per cent in 2011. Load factors give the ratio of the actual amount of electricity produced and the maximum potential output, and are a good indication of how well the industry is performing. While this is an improving picture, in order to meet the most optimistic scenario, this would need to increase to 95 per cent.

A wide range of alternative substrates are now able to be treated through AD, from fallen animal stock and seaweed, to road verge grass

government will not be able to meet its recycling targets without separate food waste collections, which will require more food waste AD capacity to treat and recycle the resulting separated food waste. “Currently, England is operating at around 50 per cent of its AD capacity and we want to see that increase,” stresses Paul Killoughery, Managing Director of Bio Collectors, London’s largest independent food waste collection and recycling company. “We are campaigning for mandatory food waste segregation in order to effect change and increase the amount that is recycled through anaerobic digestion. Bio Collectors recently hosted the government’s Environment, Food and Rural Affairs (EFRA) select committee at its AD plant in Mitcham, Surrey, to show attending MPs how the facility functions on a daily basis and allow them to experience the operation first hand.”

Unavoidable food waste

Paul acknowledges that an increased awareness of food waste has seen a lot of unsold food donated to charities and food banks, and feels there is no danger of increased AD capacity resulting in less food going to those who need it most. “Bio Collectors wholeheartedly supports the redistribution and repurposing of avoidable food waste, but there will always be some food waste that is unavoidable. The list includes peelings and banana skins as well as sludge and other by-products produced during manufacturing that are not fit for human consumption. It is vital to educate the public on identifying avoidable and unavoidable food waste to reduce the overall amount being thrown away, as well as increasing the amount that is recycled through AD. This fits into the common objective of reducing food waste and creating a circular economy.” Paul continues: “We are championing the introduction of mandatory food waste segregation, and that once food waste is separated it cannot legally be sent to incineration or landfill, meaning it must be recycled. We need to follow Scotland’s lead, where businesses producing more than 5kg of food waste a week must present the material separately. This follows changes to the law that came into effect in January last year. Less than a year later, AD sites in Scotland were full – we want to see this happening across the UK.” However, even if all inedible food waste across the UK was treated by anaerobic digestion, it would not provide sufficient additional feedstock to meet the most ambitious deployment scenarios. Fortunately, advances in technology and R&I mean that a wide range of alternative substrates are now able to be treated through AD, from fallen animal stock and seaweed, to high lignin feedstocks and wetland biomass. Judith Ford at the Centre for Doctoral Training in Bioenergy, University of Leeds, is leading a research project on the use of road verge grass as an AD feedstock. Not only could this provide a new source 14

AD & Bioresources News | summer 2017

A key part of achieving this is to ensure that all new and existing plants are operating to the best of their ability, as Ollie More explains: “One of the reasons ADBA was set up was to promote best practice and to work with the industry to improve performance. We are now in the process of delivering our Best Practice Scheme for AD, part of which covers how to monitor the AD process and the performance of an AD plant. This should allow operators to better understand how they can improve their own operation. Risk management is also a key theme – getting this under control can reduce plant downtime, improving the overall performance of the industry and the return on investment for individual projects.”

The power of R&I

While every operator has a role to play in increasing the industry’s output, serious investment in R&I could provide the sea change needed to take it to the next level. “Power from AD could provide more energy than nuclear does today, but it is currently only delivering a fraction of this potential,” says Dr Mike Mason, Research Fellow at the University of Oxford and Chairman of Tropical Power. “Further investment via targeted, collaborative research would enable a step change in the cost of AD, allowing anaerobic biotechnology to deliver at a massively greater scale than at present.”

Could R&I hold the key to helping the UK's AD industry reach its full potential?

“The Anaerobic Digestion Network primarily funds two types of research vital to industry,” argues Angie Bywater of the BBSRC-funded AD Network, based at the University of Southampton. “Firstly, we can provide funding for an academic to look at a problem for an industrial partner, such as odour control, testing of digester components or using products from digestate. Secondly, there is funding to address ‘blue sky’ questions, which may lead to future breakthroughs. Such Proof of Concept grants may look at challenges varying from how to understand and manipulate microbial consortia within a digester, to using novel bioelectrochemical systems for product recovery or as biosensors. We need a variety of cross-sectoral research in order to grow the UK’s AD sector.” Continued>>

Reaching our potential development of a research hub as a centre of global excellence; a Centre for Anaerobic Biotechnology and Bioresources (CABB). The objective is to transform AD into a low cost, multi-functional biotechnology. Such a facility would bring together and coordinate the research input of often disparate groups, to ensure the interdisciplinary vision needed to rapidly achieve the full potential of anaerobic biotechnology.

ADBA’s Best Practice Scheme should allow operators to better understand how they can improve their own operation

Angie continues: “Traditionally, the UK has been less successful than other countries in commercialising research and thus realising the advantages that R&I can bring to the bottom line. In order to address this, many research institutions set up departments for technology transfer and commercialisation, as well as closely partnering with business. Research is a vital component in ensuring that the industry can survive, thrive and export to a subsidy-free world.” To deliver the research necessary to meet the industry’s potential, stakeholders including ADBA and a number of leading universities have proposed the


AD & Bioresources News | summer 2017

Operating as a virtual centre, the core administrative function of CABB would be to distribute funds to the UK’s existing world-leading research bases. Membership of the Centre would not be exclusive, but initial support comes from the Universities of Oxford, Southampton, Reading, Newcastle and Cranfield, Imperial College and the Royal Botanic Gardens at Kew. ADBA would play an integral role in facilitating industry participation and successful research translation. A total budget of £50m over 5-7 years is being sought, and it is believed this will provide better value and outcomes compared to the piecemeal, competitive grant environment that is currently in place, and which does not lend itself well to the interdisciplinary research requirements illustrated above.

Better community engagement

However, there is no point in increasing the efficiency of AD plants if it proves impossible to build them. Not only is finance required, but so is planning permission. Professor Patrick Devine-Wright from the University of Exeter studies why communities object to energy infrastructure projects: “It varies with the technology, but broadly speaking objections centre on the impact on the landscape and on nearby residents; whether the people who are impacted by a project feel that they have any say in the decision and who benefits from the project compared to who’s impacted by it.”

Reaching our potential The proposed Centre for Anaerobic Biotechnology and Bioresources would act as a research hub and centre of global AD excellence

“Another issue that comes up a lot is trust, which is important in terms of who is listened to,” continues Professor DevineWright. “The earlier that developers speak to communities, the more chance they have to build trust, so earlier engagement is definitely something for developers to improve. In addition, developers are increasingly offering some kind of community benefit, so that impacts are seen to be fair. When communicating with residents, instead of seeing this as about information or facts that need to be conveyed, it’s more interesting to think, how do I create a narrative for this project that shows how this technology is suitable to, or fits into, the place or landscape that I am hoping to construct it in?” This emphasis on communication reflects a wider need to improve the understanding of AD across all levels of society, from the general public to businesses, politicians and NGOs. “ADBA is working to develop communications materials that help to address some of the most common questions around AD, for example concerning the sustainability of using crops as feedstock, whether AD diverts edible food away from people and animals, and the impacts of an AD plant on local communities in terms of odour management, the likelihood of accidents, freight transport, etc,” says Chris Noyce. Such activities may seem relatively minor when you consider our goal of 77 TWh, but when added together, a series of small steps – towards improving

access to feedstock, lobbying for long term political support, securing investment in R&I, and supporting best practice at existing AD facilities – can go a long way towards turning our industry’s potential into a reality.

Technology Focus: CHP

Smart CHP selection

Cathal Dorrian, Project Manager for Scottish Water Horizons (a commercial subsidiary of Scottish Water), discusses what AD plant owners need to consider when choosing a CHP unit. “Traditionally, power plants emit heat during the production of electricity which is released into the environment through cooling towers, flue gas, or by other means. Co-generation, or combined heat and power, is the means by which this ‘waste’ heat is captured and used, either as a heat source or to generate additional electricity through steam powered engines. Tri-generation, or combined cooling heat and power, is where the waste heat is used for both heating and cooling, typically in an absorption refrigerator. When faced with the decision over whether to invest in a combined heat and power (CHP) unit, there are a number of questions that will arise.

How do I know if I’m selecting the right unit for my project? What are the key factors that will drive the success of this investment? Is there any legislation that I need to be aware of? In terms of selecting the right CHP for an AD plant, a developer must first determine if the objective is to meet an electrical demand or a heat requirement, as this will drive engine size. The second consideration relates to the electrical load – is the goal to match the electrical load profile of your premises, or to generate as much electricity as possible for the income from the export tariff? In either case, the power generated will be constrained by the fuel available so it is vital to work with an experienced supplier when determining the size of the CHP. Too small means not taking full advantage of the fuel available, whereas a CHP that is too big will not only cost more, but will run less efficiently and may result in a reduction in operational hours due to a lack of gas availability. Consideration also needs to be given to purchasing a single unit or a twin pack. For example, should you buy one 1 MW unit, or two


AD & Bioresources News | summer 2017

500 kW units? While a twin pack gives you more flexibility in that it allows you to keep one unit operational whilst the other is offline (for servicing, for example), capital and servicing costs will be higher with the twin pack. The maintenance and service contract is critical too. Does the supplier offer 24hr call out, telephone and internet support? What is the availability of critical spares? Do they have service level agreements? What is the geographical location of their maintenance engineers? These are important considerations because downtime equals lost revenue and increased costs. Regarding legislation, investing in CHP technology requires an awareness of the MCPD Directive (Medium Combustion Plant Directive), which limits the amount of certain pollutants into the air. CHPs emit sulphur dioxide and nitrogen oxide and the Directive places limits on the emission levels of these gases, depending on the type of fuel and technology used. One suggestion is to install a carbon filtration unit alongside the CHP to clean the gas before it is processed by the engine, thereby reducing emissions. Continued>>

Technology Focus: CHP


AD & Bioresources News | summer 2017

Technology Focus: CHP Finally, when investing in a CHP plant, it can pay to be creative by looking at encompassing other technologies which will improve energy efficiency even further. Some plants combine CHPs with fuel cells and battery storage to further improve technical and environmental performance. Expanding the capabilities of CHPs in this way will ensure that the technology is not only here to stay, but will be developed even further in the years to come.”

Who controls your CHP?

Building an AD plant is a huge undertaking that requires a myriad of decisions. But James Thompson, Director of Gen-C, warns developers not to overlook who owns the CHP: “More often Gen-C’s James than not, the CHP is provided by Thompson a separate company, usually a partner of the AD supplier, and few questions get asked about its control, service and accessibility during the procurement process,” he states. “What often happens is that a few months after commissioning, the owner realises that they are locked into a lengthy service contract with very little control over their CHP, and are unable to make relatively simple changes to enhance the operation without a password or other access key.”

Gen-C distributes Sandfirdren gas engines, parts, systems and Motertech gas engine upgrades

With this in mind, James suggests some key questions that potential owners need to be asking of their AD plant supplier: • Can I source my own CHP? • Can the power output be spread between two engines? • Will the CHP have a compulsory service contract? • Can I liaise directly with the CHP supplier?

• Can I have a flexible service contract where I can carry out the simpler tasks, such as oil changes and spark plug cleaning, gapping, replacement? • Can I walk away from the service contract without the controls being locked? • Is the control panel open access? • Can I get remote support?

Technology Focus: CHP “There are plenty of independent CHP options available now and owners should give this area the same, if not more, consideration than the AD plant itself. After all, it’s the CHP that generates the income – owners should be demanding more control,” adds James.

Rob Greenow’s on-farm AD facility in Staffordshire

Beating the FIT trap

Robert Greenow runs his own AD technical and biological support business, BioG-UK, and applied for planning permission to install an AD facility on his farm in Rob Greenow Shebdon, Staffordshire. As well of BioG-UK as providing a reliable source of power – making the farm completely self-sufficient in terms of energy use – the AD plant would also supply heat to dry grain, help to minimise crop waste and produce a nutrient-rich biofertiliser. However, after a lengthy planning stage and a drawn-out development process, Robert had less than a month before his FIT pre-accreditation period expired to install a CHP engine. Needing to move quickly, he turned to engine installation and maintenance specialists, CooperOstlund. Once specified, the engine was sourced and installed within six weeks. CooperOstlund then undertook


AD & Bioresources News | summer 2017

full commissioning and got the engine up and running ahead of the pre-accreditation deadline. The facility now supplies enough electricity to the National Grid to power 500 homes. “If the engine went offline the costs would be substantial so it’s comforting to know that I can call on dedicated technicians at any time of the day

or night,” says Rob. “The facility is now generating nearly £50,000 a month – a highly valuable addition to the farm’s income.”

AD increases farm income

Our External Affairs Manager, Jon Harrison, reports on the latest waste news from Parliament

Don’t forget the home front as Brexit begins

Farms across the UK reported a steady rise in income from renewable energy, including AD, in 2016 according to figures from the Office for National Statistics (ONS). Their report on the 2016 Farm Business Survey of farm income showed a three per cent rise in income from renewable energy from 2015’s figure of six per cent. In total, £580m was generated from diversified activities by 34,900 farms, with an average diversified enterprise income of £16,600. Different categories of diversification that contributed to farm income included letting out buildings, tourism, sport and recreation, as well as renewable energy.

England continues to lag behind the devolved administrations in the roll out of separate food waste collections, a critical policy for reducing CO2 emissions and providing feedstock for the UK AD industry. Parliament’s Environment, Food and Rural Affairs Committee has continued its inquiry into the impact of food waste by inviting Chief Executive of WRAP Marcus Gover and Special Adviser Andrew Parry to give oral evidence, following on from a previous session with ADBA Chief Executive Charlotte Morton. Andrew outlined the UK’s contribution towards the UN Sustainable Development Goals on food waste reduction and the need for a joined up food waste strategy running from food manufacturers through to households. MPs on the Committee raised concerns that the waste hierarchy is not being correctly followed, partly due to a lack of clarity on responsibility for enforcement.

GIB bought by Australian bank The Green Investment bank (GIB), set up by the UK Government five years ago to fund renewable and low carbon projects, has been sold to Australian bank, Macquarie. The Treasury secured £1.7bn through the process, with a further £600m of liabilities being taken on by Macquarie. GIB has invested about £800m per year so far in renewable projects, which includes government funding of £1.5bn since 2012.The deal with Macquarie should see that rise to £3bn per year over three years. GIB will retain its name and headquarters team in Edinburgh. Although all the shares are transferring, the government is appointing independent trustees with the power to ensure it continues to have an environmental mission.

Elsewhere, the new government will be turning its attention to its Industrial Strategy. With its focus on innovative R&D, boosting job numbers and regional growth, the Industrial Strategy will be a key opportunity for the AD industry to demonstrate how it can help contribute towards these important goals. We have responded to the consultation, encouraging the establishment of sector deals for agriculture and the bioeconomy – two areas where AD could make a real difference to our economy. A focus on these sectors is critical given the significant changes to the regulatory environment for farmers, as a result of our impending exit from the European Union. We are also working to make AD central to the government’s Bioeconomy Strategy and Clean Growth Plan, ensuring that the benefits are recognised across ministers’ policymaking agenda.

Waste industry safety hub launched The new Waste Industry Safety and Health Forum (WISH) website, hosted by CIWM, has been launched. The site provides a one-stop-shop for all WISH guidance previously hosted on the HSE (Health and Safety Executive) website and hosts both formal guidance documents and other resources, including good practice case studies. Chris Jones, Chair of WISH, said: “Waste management is a rapidly developing industry facing many health and safety challenges. The aim of the new WISH website is to give operators easy access to the advice and guidance they need to meet these challenges.” 24

Advice Clinic: Operating well

Advice Clinic: Operating well In our regular advice column, ADBA members provide answers to some common AD queries


How can I get more methane from the feedstock I’m putting into my plant?

There are many methods of increasing methane yield in a biogas plant, ranging from equipment improvements to changing process conditions. We’re focused on developing enzymes that can be added directly into a digester to help improve the efficiency of feedstocks. Enzymes work by breaking down complex polymeric substrates into smaller oligomers that are more suitable for biogas-producing organisms. In other words, they help turn large insoluble fibres into soluble components that can be converted into methane. As an example, OPTIMASH® AD-100 works on cellulosic materials, such as animal and farm wastes, agricultural residues, paper products and wastewater sludge. The use of this enzyme in anaerobic digestion has been shown to improve reaction kinetics and convert materials that were previously leftover and unused. Additionally, enzymes can significantly decrease the viscosity in the reactors, rendering the materials more flowable and easier to pump.

How do we improve feed efficiency?


How do I know which nutrients my AD plant is lacking?

This is a question we are often asked and there are a simple set of steps operators can take to determine if this can be improved. Firstly, we need to understand the input/output ratio. Is the plant generating the level of gas we would expect based on its feed composition? Operators need to be realistic about the quality of their materials and gas potential of their feed. For crop-fed plants, reducing energy losses during storage is often a good place to start.

Most digester feedstocks lack essential elements such as cobalt, iron, nickel and selenium, essential to the health and efficiency of a plant’s biology. Each micronutrient plays its own separate role in the overall health of a plant and experience tells us most systems will lack one or more of these. In organic solids systems, deficiencies can be spotted by high VFA levels, poor methane production and poor stability with regards to acidity. In wastewater treatment systems, this can be seen by poor chemical oxygen demand (COD) reduction and poor granulation.

Secondly, analyse the contents of the digester. Is there any accumulation of volatile fatty acids (VFAs), or deficiencies (or large excesses) of critical trace elements that will inhibit production (copper, nickel, zinc, iron, boron, cobalt, manganese, molybdenum, selenium)? Is the NH4 level high? Dependent on pH and operating temperature this will be converted to free ammonia, which is toxic to the biology of an AD plant.

Trace element additives can provide and augment these essential elements in a fully bio-available form. A digester sample can be analysed in a laboratory for its methane potential with AMPT (automatic methane potential test) equipment. This will show what nutrients the digester is lacking and what needs to be improved. Trace element additives, such as Nutromex®, can then help to increase biogas volume and quality, and provide better digester stability.

Thirdly, is the tank well mixed and not too viscous, with no floating or sinking layers or feed balls? Where mixing is an issue, gradients of temperature, VFAs and nutrients can occur, or even substrate bypass, where material can quickly pass through the primary digester without having time to break down. By following these steps, the answer to the original question will be answered and any solutions to improve the feed efficiency can be implemented.

Residue feedstocks unlocked Future Biogas Systems Ltd (a subsidiary of AD developer Future Biogas) will be joining forces with Biogas Systems GmbH of Austria to showcase the Economizer SE, which is now available for purchase in the UK. The pre-treatment system strips lignin from previously difficult to use biomasses, such as straw and farmyard manure, and makes the dry matter readily available for digestion. With a gas yield similar to beet pulp the potential annual saving to an AD plant is circa £500,000 pa, depending on local feedstock availability. The first Economizer was commissioned in the UK earlier this year and in its first 48 hour run, it exceeded output expectations by 10 per cent. By the time of the show, there will be three units commissioned in the UK and several more under development. The team is looking forward to explaining to visitors how this groundbreaking technology is changing the biogas industry. Stand K303

Tackling fuel poverty The UK now has over 70 biogas upgrading plants injecting biomethane into the grid, with a capacity of <3.6TWh/y – enough to displace four 60,000 tonne LNG tankers. However, GSMR, sustainability criteria, RHI tariff uncertainty, low gas prices and limited network capacity all pose unique obstacles to be overcome. Puregas Solutions’ latest project involves upgrading 2,000 Nm3/h of biogas from food waste to biomethane and compressing it to 250bar. The bioCNG is fed into trailers for transportation to remotely located CHPs, where the electricity and heat generated is supplied to local homes and businesses. Elsewhere in Europe, several new projects are now underway to liquefy the biomethane to produce bioLNG for transportation. It’s clear that biomethane is playing an important role in providing flexible, cost effective, renewable energy solutions to off-grid customers, helping to tackle fuel poverty. Stand J405

Launch of BioBuster pre-treatment Landia will debut the BioBuster, a new non-pumping pre-treatment that dramatically breaks down solid matter to enhance the performance of an AD plant. Designed to be dropped in and ready to work within seconds, the BioBuster produces a completely homogenous substrate that greatly simplifies pumping to a digester. Chopping and macerating with an uncompromising knife system, it lowers viscosity, with tests also showing a 20 per cent saving on power consumption when compared to an equivalent sized propeller mixer. Particle size is appreciably smaller, with dry matter of eight per cent being about the same when using maize and slurry combined.

More biogas, same feedstock Metamo are true process engineers, always looking for better solutions to the typical problems faced by AD operators. This year, the company will showcase technology which promises to get AD plants punching above their weight. This low maintenance technology sits alongside a digester, continuously processing the substrate and breaking down the cell structure to enable greater fermentation and increased flow. The result is more biogas (with a higher methane content) from the same quantity of feedstock – or the ability to use a lower quality feedstock to achieve the same results – with an increase in yield of between 10 and 25 per cent. Sounds too good to be true? They’ve been testing all spring and can’t wait to share the results with visitors to their stand. Stand F203

The purchase price of a pump is typically only five per cent of the lifetime costs of running the equipment – spare parts, energy use and downtime all make up the total cost of pump ownership, so it makes sense for each pump to be as efficient as possible. To this end, SEEPEX will be demonstrating its Smart Conveying Technology (SCT) pumps at UK AD & Biogas, which can be adjusted to regain performance and maintained without pipework removal to reduce downtime. The company will also showcase the accurate flow characteristics of its progressive cavity pumps. Accuracy, reliability, repeatability, low pulsation flow, simple installation and control are just some of the properties that enable optimum dosing of nutrients, additives and chemicals into processes. Thames Water has recently replaced diaphragm pumps with SEEPEX pumps at its Hogsmill site for ferric chloride dosing, reducing maintenance and downtime, and the team look forward to discussing this project and more with visitors to its stand.

UK AD & Biogas and World Biogas Expo 2017 Exhibitor Preview Money-saving energy recovery equipment HRS Heat Exchangers will unveil how its pasteurisation technology with energy recovery is helping AD plant operator Muntons prevent almost 800 tonnes of CO2 emissions and save more than £2.5m in energy and disposal costs. Visitors will learn how the HRS 3 Tank Batch Sludge Pasteuriser System with Energy Recovery not only helps certify digestate (reassuring farmers of its quality), but also helps Muntons save up to 70 per cent of the heat required for pasteurisation, by transferring energy from the hotter (pasteurised) sludge to the colder (unpasteurised) sludge. Matt Hale, International Sales Manager at HRS, comments: “Working with a company like Muntons to deliver a truly revolutionary waste treatment plant shows exactly what’s possible in terms of implementing the circular economy. Both in trials and in the fields, the biofertiliser is demonstrating just what a valuable resource it is. We look forward to showing visitors to our stand how they can replicate the successful model being pioneered by Muntons.” Stand D501

Members’ News & Views Combined AD and thermal hydrolysis innovation from Veolia Veolia Water Technologies has completed the soft launch of its Exelys combined thermal hydrolysis and anaerobic digestion technology in the form of a modular and highly versatile package system. The new system combines features such as a small footprint, is fully pressure and factory tested, and boasts a ‘plug and play’ design, making it suited to rapid process upgrades, easy retrofits, or urgent installation. The compact units also offer the same benefits as the established Exelys process: low steam consumption, up to 35 per cent fewer dry solids, up to 50 per cent more biogas, no odours, and a pasteurised digestate. Mike Froom, Business Development Director at Veolia Water Technologies UK, says: “We hope this will open up a whole new range of options for customers who need to upgrade existing processes, get more from constrained sites, or simply make their capital programmes work harder.”

New biomethane opportunities for Schmack Biogas Schmack Biogas has been awarded a second contract for the construction of a biomethane plant in Sourdun, northern France. Due to be completed by the end of 2017, the plant is expected to produce 250 Nm³/h of raw biogas in the first phase of the development. However, the design already includes a possible second development phase to increase production to 500 Nm3/h. The raw biogas will be refined to a methane content of at least 97 per cent by means of pressure swing adsorption. As a result, the biogas will be of natural gas quality and will be able to be fed into Sourdun’s local supply network.

Upgrading solutions for plants of all sizes The UK biogas industry is evolving rapidly, partly due to the challenging and unpredictable nature of government policy and its financial support structures. Central to this evolution is biogas upgrading and the subsequent use of the product gases; biomethane and CO2. HoSt Bio-Energy UK has seen increasing customer interest in its membrane upgrade technology across the whole of its capacity range, from 2,000 Nm3/h down to just 50 Nm3/h of biogas input. At the smaller capacity end, there is also interest in further biomethane compression to compressed natural gas (CNG) c. 250 bar. This can be used for direct vehicle fuelling or for road transfer via a virtual pipeline to a suitable grid-connected facility with spare injection capacity. At the larger capacity end, HoSt has seen significant interest in integrated CO2 liquefaction systems, where CO2 is separated from biomethane as part of the membrane upgrade process and stored on site. This is of particular interest where CO2 can be sold as food-grade quality. This combined upgrade/liquefaction technology was recently installed at a HoSt biogas plant in Hereford. In addition to larger scale deployment, HoSt is also building small scale biogas upgrade plants and integrating this technology with CNG compression and filling stations for vehicle fuel. HoSt membrane technology allows this scaling of capacity and offers the flexibility of modular expansion, and the


AD & Bioresources News | summer 2017

company has direct experience of combining biogas upgrade, CNG and vehicle filling stations, with recent projects in Finland and Sweden. Following a period of successful operation and optimised performance, many AD plants have the capability to produce more biogas than can be directly used on site. In these cases, additional biogas could be upgraded to biomethane, compressed to CNG and either transferred to a suitable grid injection point or used as vehicle fuel, possibly fuelling the very trucks that deliver the feedstock or remove the digestate.

Members’ News & Views First Economizer SE commissioned in UK

McGrane Nurseries’ AD plant is expected to go live in early 2018

The system unlocks the digestible capacity of materials with high levels of lignin

Future Biogas and Biogas Systems GmbH have commissioned the first Economizer SE at an AD plant in Nottinghamshire. The Economizer SE, a front-end process system which unlocks the full digestible capacity of materials with high levels of lignin, has the potential to revolutionise the way biogas is produced. The system allows materials such as wheat straw and soiled straw bedding to be digested rapidly, using only limited amounts of electricity and some high-grade heat. This enables the average unit to replace around 19,000 tonnes of purpose-grown crop with 7,500 tonnes of wheat straw, representing a potential annual saving to an AD plant of around £500,000 per year, depending on local feedstock availability. Philipp Lukas, Managing Director and founder of Future Biogas, states: “We are very pleased with the system, and since signing a distribution agreement for the UK last year we have been busy engaging with the market. A second unit arrives in the UK for installation at a Norfolk plant at the end of this week and a third is already being fabricated in Austria for a site on the south coast.”

Aqua Enviro supports sewage plant upgrade Thames Water's Riverside Sewage Treatment Works, located in Rainham, Essex, has undergone a large upgrade to its sludge treatment plant. Aqua Enviro's team of process scientists and engineers provided support on one of the first Thermal Hydrolysis Plant (THP) assets to be installed in the Thames Water region. The thermal hydrolysis process is used to enhance the plant’s existing AD processes. Using the THP, the AD process can enhance energy while creating a pathogen free final product. David Fenech, Thames Water Operations Manager, said: “Aqua Enviro have provided excellent support during a difficult period; always professional, willing and adaptable in changing circumstances.”

CWE helps nursery to achieve ROCs for 2 CHPs Electrical installers CWE have enabled McGrane Nurseries to achieve the Renewable Obligation Certification for their two CHP engines. Based in Craigavon, Northern Ireland, McGrane’s 750 kW AD plant is currently under construction. Due to complete in Q1 2018, it will consist of three tanks and will process maize/miscanthus and pig waste. In an effort to use the resulting renewable electricity, two on-site CHPs were ordered by the client. CWE were tasked with installing new MCCB panel boards to control and sub-distribute the power and resultant hot water circulating the nine acres of glasshouses, in which potted plants are being grown. The project relies on a bespoke controls system and CWE, through working closely with other specialist contractors, have designed and manufactured control panels to interact between the pump sets, heat monitoring, actuators, thermostats, excess heat destroyers, pressurisation and expansion vessels, to offer a fully automatic process. Against a very tight ROC deadline, the project was delivered on time and within budget.

Cool plant upgrade for Puregas Puregas Solutions has just Sub-zero Scandinavian completed the installation and conditions weren’t enough commissioning of a CApure CA30 to deter Puregas Solutions biogas upgrading plant in Forsbacka, 200km north of Stockholm, Sweden. The plant, which was completed in sometimes sub-zero temperatures, will convert around 30,000 tonnes of locally sourced domestic and commercial food waste into 650 Nm3/h of raw biogas. The project is one of the largest of its kind in Scandinavia and will use a dry fermentation process: the high solids substrates remain static during the fermentation process, reducing power consumption, the need for internal mixers and agitation, and the potential for breakdowns. The upgraded biomethane will be compressed to 250barg; the bio-CNG will then be used to fuel vehicles locally, and will be transported to remote filling stations via trailers. The digestate will be used by local farmers as part of a certified ecological fertiliser programme.

Members’ News & Views Biogen acquired by Ancala Bioenergy

UK AD operator, Biogen, has been acquired by Ancala Bioenergy, an independent infrastructure investment management company. The price for the acquisition has not been disclosed. Biogen has seven AD sites in England and Wales which process 250,000 tonnes of food waste a year and generate 13 MW of renewable energy. The company will provide Ancala with a platform from which to expand into the bioenergy sector.

Landia’s GasMix helping to tackle London’s food waste Landia’s GasMix system is proving instrumental in tackling 75,000 tonnes of London’s food waste each year at Bio Collectors’ AD facility – the only gas to grid food waste operation in Greater London. Bio Collectors has contracts with the likes of Sainsbury’s and Pizza Hut, and when choosing the GasMix system for the Surrey plant, Managing Director, Paul Killoughery, said: “Very early on we decided that we definitely didn’t want mixers inside the tank that we couldn’t get to. With Landia’s externally mounted GasMix system we have equipment that is easily serviceable and repairable from the outside. Although as it happens, we’ve had no major problems whatsoever.” “Good mixing has also produced top quality digestate,” adds Paul. “It is high in NPK and very popular with arable farmers who see increased yields. Our PAS 110 test for residual biogas conclusively shows that our mixing system is working to an extremely high standard. It is a major benefit to the whole process.”

Joint trial for Marches Biogas and Geotech

Marches and Geotech are working to convert H2S levels in biogas into elemental sulphur

When Marches Biogas was commissioned to build a 500 kWe AD plant near Ludlow back in 2014, it also began developing a new system to convert the hydrogen sulphide (H2S) in biogas into elemental sulphur via chemical scrubbing, ensuring only the cleanest biogas makes it into the CHP unit. However, this method requires continuous gas monitoring and sampling before and after the biogas scrubbing procedure. Already using analysers from Geotech, Marches installed Geotech’s new BIOGAS 3000 fixed analyser to monitor the gas quality of CH4, CO2, O2 and two-range H2S before and after the scrubber. It provided Marches with detailed gas composition results, allowing them to control the H2S levels in the biogas and calculate the conversion rate of H2S into elemental sulphur. Pavel Psenicka, Process Engineer at Marches Biogas, explains: “We have a number of new AD plants in development for 2017 and the BIOGAS 3000 will be a standard component of each plant. Our future plan is to launch the H2S scrubber to develop a similar technology to recover ammonia from the biogas, which would operate on a similar basis to the current system.”

Third deal struck as firms outline commitment to waste-to-energy innovation Following two previous collaborations, EnviTec Biogas has once again linked up with temporary energy provider Energyst CAT Rental Solutions, as work on its most recent project in Cheshire continues. With an ever-stronger global focus on the need for green energy and better waste management, the renewable energy industry is continually evolving. Setting itself apart as an innovator in the field of green energy solutions, EnviTec Biogas is committed to enabling organisations to turn waste into useful energy. The double benefit of this allows value to be maximised while cutting the environmental cost of waste. In the long term, Energyst CAT Rental Solutions believes concentrating on providing an alternative energy source, while simultaneously cutting waste, is a blueprint for the future – and that temporary power has a vital part to play in guaranteeing that supply. To meet those objectives and ensure an optimum operating environment, EnviTec has been supported by Energyst with the supply of equipment vital to the anaerobic digestion processes put in place in the firm’s last two projects. Following a project in Grindley, Staffordshire, last summer and with a third contract due to get underway this year, Energyst says commitment to optimum performance and trust are key to introducing and maintaining AD facilities – allowing for the most efficient process to be implemented. To this end, Energyst supplied EnviTec with a 550 kW hot water unit and 250 kva system for its most recent project, which began in October. The use of temporary boilers and power has enabled construction, as well as quicker production, as Energyst Account Manager, Richard Barden, from the West Midlands depot, explains: “Drawing on prior performance from a similar site, we knew that the product range fitted perfectly with the customer’s requirements. As soon as we found out about the new AD plant we immediately visited the site to meet the customer and offered to provide a tailored solution. We supplied a 550 kW boiler to heat the digestion tank to

promote a bacterial reaction in the waste-to-energy process, while a 250 kva supplied power to the boiler and remaining equipment.” The green energy market is seen as a vital part of the fuel industry to reduce reliance on natural gas, while meeting government targets on waste reduction. EnviTec’s Project Co-ordinator, Sean O’Neill, adds: “The two-fold benefit of using anaerobic digestion to create biogas as a renewable source of energy makes the introduction of this system a great asset. An efficient, well-managed environment is key to success when implementing a biogas system to ensure optimal returns. Temporary power solutions go hand in hand with the creation of renewable energy plants by providing support throughout construction and essential back-up. By renewing the relationship with Energyst, this project can benefit from the expertise and trust built up over previous projects.”

Policy RHI update – implications for industry Due to the calling of the general election, the Department for Business, Energy and Industrial Strategy (BEIS) was not able to put the reforms to the RHI before parliament. BEIS was also unable to pass emergency legislation, which would have updated the RHI degression triggers. This means the overall RHI scheme trigger will remain at £578m for the ‘total expenditure anticipated for subsequent year’ and at £289m as the ‘expenditure threshold when calculating C for the purposes of regulation 37A’ (ie half of the total anticipated). The RHI is likely to continue to be above its thresholds until the new legislation is passed. Biomethane has an expected growth rate in legislation of £15.2m per quarter and at the current tariffs it is unlikely that it will be 50 per cent or above this growth. However, biomethane is likely to be above its total expenditure threshold of £175.4m, which could mean a five per cent degression.

For up to the minute information and advice on regulations, consultations and government news, contact our Head of Policy, Ollie More T +44 (0)203 567 0751 E

What does this mean in English?

While the degression mechanism can seem hard to understand, this essentially means that the current biomethane tariff of 3.56p/kWh for plants up to 40 GWh/year could fall by five per cent to 3.38p on 1 July. If the proposed new legislation is not in place by 1 October, then the tariff could fall by a further five per cent on 1 October. Any plants commissioning in this period would be able to claim the new higher tariff once any new legislation is in place, although this would not be backdated to the commissioning date.

What does this mean for the industry?

The delays to the implementation of the RHI reforms are hitting the industry – we’ve heard from over 10 projects that are being delayed. We will be writing to the new ministers as soon as they are in place to explain the damage that has been caused and why they must act quickly to pass the legislation. Our view is that a new government is likely to be broadly in favour of the reforms, but there will still be risks over the timescale – ministers need to be appointed, briefed, and then put the legislation before parliament. There is then the usual 6-8 week parliamentary process (excluding any recess), which could take us into the autumn.

Reducing gas to grid costs

BEIS to study methane leakage from AD plants

We have now submitted our response to National Grid Gas Distribution and DNV GL’s consultation on the Future Billing Methodology. Our response supports the project in its proof of concept investigation into whether gases of different calorific value (CV) can co-exist on the same gas network.

BEIS is hoping to conduct a study on methane leakage from AD plants, by installing sensors to monitor methane levels. The Department feels that existing literature on methane leakage from AD plants does not reflect the reality. With methane having a global warming potential over 20 times that of carbon dioxide, any methane leakage has a huge impact on the greenhouse gas abatement of AD.

We believe that the outcomes of this project could help grow biomethane supplies. Biomethane from AD currently requires the addition of propane before it can be injected into the gas grid, a costly process which presents a barrier to new projects. As a fossil fuel, adding propane is also contrary to the decarbonisation objectives biomethane delivers. Download our final response from or to find out more about this project, contact

Get involved We are keen to hear from anyone that has already used technologies such as methane detection cameras or more sophisticated methods on whether they were able to improve plant performance. We also want to hear from anyone that may want to volunteer their plant for monitoring – it's a free service that may help to find and reduce leaks, and increase profit. If significant methane leakages are found, we would not be surprised if some rules were brought in, so this needs to be a focus for everyone in the industry.

Policy Get FIT for summer with Ofgem Following the implementation of the reforms to the Feed-in Tariff (FIT), Ofgem has now released a range of new guidance. Ofgem’s new Guidance for Renewable Installations (Version 11) is for ROO-FIT installations that are seeking accreditation under the scheme from 1 May 2017. It provides an overview of the FIT scheme, its eligibility criteria and explains the process of seeking accreditation and preliminary accreditation. After consultation, Ofgem has also released its guidance on sustainability criteria and feedstock restrictions. Affecting all new applicants to the FIT, the guidance sets out the sustainability requirements and feedstock restrictions effective from 1 May 2017. In regards to feedstock classifications, Ofgem has accepted that it: “...may periodically review and update this list, if sufficient evidence emerges to indicate that a substance should be treated differently. Where further information comes to light we will liaise with other relevant parties such as the Renewable Transport Fuels Obligation (RTFO) administrator, RHI and RO with the potential to reassess if we deem necessary.”

To provide feedstock information, Ofgem has also released a new Fuel Measurement and Sampling (FMS) questionnaire and has revised its Biogas Apportioning Tool. This tool can be used by FIT generators or RHI participants who are using AD to produce biogas for combustion or biomethane for injection and are seeking to apportion the consignments of biogas or biomethane derived from multiple feedstock consignments. It can also be used to identify the proportion of biogas or biomethane which is produced from waste or residue feedstock. In addition, the new Fuel Classification Flow Diagram can be used by generators or auditors to classify fuels under the FIT or RO. Contact or visit our policy blog at for links to all of Ofgem’s new guidance and tools.

New air quality plan brings opportunities for biomethane The UK Government, the Scottish Government, the Welsh Government and the Department of Agriculture, Environment and Rural Affairs in Northern Ireland have launched a consultation on proposals to improve air quality in our towns and cities. Nitrogen dioxide (NO2) pollution is the primary cause of poor air quality, which is exceeding legal limits along specific roads in a number of urban areas. The proposed changes could further stimulate the use of biomethane as a vehicle fuel. Compared to diesel, biomethane offers lower NO2 and particulate matter levels and also reduces CO2 emissions, critical for decarbonising transport. The consultation on ‘Tackling NO2 in towns and cities’ runs until 15 June. Members can access the consultation document on the Defra website:

Setting out the role of AD in the UK Industrial Strategy In April, we submitted our response to the Industrial Strategy green paper consultation. The consultation sought views on ten ‘pillars’ where the right policy could lead to increased productivity and economic growth throughout the UK, namely: science, research and innovation; skills; infrastructure; business growth and investment; procurement; trade and investment; affordable energy; sectoral policies; driving growth across the whole country; and creating the right institutions to bring together sectors and places. Our response details the potential growth of the AD industry, including the energy and non-energy benefits AD can deliver and what we need from government to achieve this. We propose that AD be part of two wide, ambitious sector deals to which government support could yield economic growth, job creation and export potential – each of which are clear goals of the Industrial Strategy. The proposed sector deals are agri-tech and the bioeconomy.

Agri-tech sector deal

The government should support a sector deal for sustainable agriculture, including AD, which would deliver in this sector: • 15,000 regional jobs; • £1bn in CO2 savings per year; • £0.9bn reduced gas imports per year; • £0.18bn avoided fertiliser imports and emissions per year; and, • Up to £1.5bn saving in reduced agricultural payments for soil quality, biodiversity and rural economy support (currently the UK CAP bill). Our analysis shows that investment in the agri-tech sector deal would contribute £0.5bn net to the UK economy per year.

Bioeconomy sector deal

The government should support a sector deal for the bioeconomy, including AD, which would deliver in this sector: • 41,000 jobs; • £1.1bn in CO2 savings per year; • £1.1bn in reduced gas and fertiliser imports per year; • £4.9bn in exports per year; and, • Improved energy and food security. Our analysis shows that investment in the bioeconomy would contribute £4.9bn net to the UK economy per year.

ADBA R&I Forum 2017 Review

Learning from the past to shape our future Our 2017 Research and Innovation (R&I) Forum, held in partnership with the Anaerobic Digestion Network (ADNet), provoked some real debate about the future of research, and of the AD industry. Half the sessions focused on research that has already had an impact on the industry. Research into trace elements has been conducted over the decades and is now a standard part of industry practice; research into digestate has built confidence along the food supply chain; and research into degradation technologies has allowed operators to understand which technologies work and at what cost. In Ireland, as outlined by our keynote speaker Jerry Murphy of University College Cork, research has provided an insight into the potential for AD to contribute to renewable energy goals: AD could deliver five per cent of Ireland’s transport fuel, for example. In addition, many of the operators in the audience appreciated understanding how trace elements work their magic – they may already know that trace elements improve plant performance, but understanding the science behind them will improve their use further. The other half of the sessions concentrated on how research could transform the industry in the future. This year’s Forum was about ‘thinking global’ and we heard from Professor Charles Banks on his visits to different parts of Africa and India to learn more about what researchers there see as the main challenges. Dr Mike Mason, meanwhile, talked about the potential in semi-arid parts of the world to grow both food and fuel crops. However, in order to meet the global challenges we face, we still need to understand more of the fundamentals of AD, including the different reactions taking place and the microorganisms involved.


AD & Bioresources News | summer 2017

Feedback from industry members struggling to develop new projects and stay in business is often centred around the question, ‘How is this fundamental long-term research going to help my business today?’. Professor Tom Curtis tackled this in his presentation by saying that we need to conduct research both on short-term topics that might give a return of a few per cent, but also on longer-term research that might give a 100 per cent return or more, albeit in eight years’ time. This was the third R&I Forum attended by our Policy Manager, Ollie More, who concluded: “After hearing the different arguments, I’ve formed the view that we need a huge investment of research funding into the fundamentals of AD and how parts of the process can be sped up. But we also need to showcase to the AD industry just how fast some of the reactions are already taking place in labs – perhaps a topic for next year’s Forum!”

R&I Update Greening methane for tomorrow The Wales Centre of Excellence for Anaerobic Digestion at the University of South Wales has developed the AERIOGENÂŽ biomethanation process, which aims to deliver grid scale, renewable energy storage, convert industrial waste gases to low carbon fuels and increase methane production at AD plants. Through the conversion of H2 and CO2 or CO into methane or liquid intermediates, the process enables the inter-operability of the electricity and gas networks. It allows grid management of intermittent renewable energy, reduces constrained power and constraint payments, and facilitates the production of low carbon gases and chemicals. The process can be deployed at small, medium and large scale, with energy storage capacities of 250 kW to thousands of megawatts being possible. My research team has focused their work on developing microbial enrichment strategies, enhancing gas transfer efficiency and control of chemical parameters to deliver a robust biotechnology process. The process allows intermittent operations without a performance decline, the system nutrients are recycled and microbial cultures are maintained over long periods of time, all of which have enabled the group to deliver the highest gas throughput achieved to date by any equivalent microbial process, and achieving a gas output quality of over 99 per cent methane. Development work is continuing, in particular to increase process efficiency and reduce costs by further improving gas transfer rates and microbial

syntrophies, aimed ultimately at increasing the technology readiness level and facilitating process integration and full scale deployment. The potential for reducing parasitic energy load to below three per cent of energy output is also currently being investigated. The process has been developed through R&D funding obtained from ERDF, Welsh Government, Innovate UK, BBSRC, and the private sector and this has led to a significant upgrade in the University facilities that support C1 gas conversions and the development of specialist know-how and IP. The team aims to see the technology deployed in the UK and elsewhere in the next two to five years.

R&I Special Advertorial Feature

Demonstrating the power of enzymes Late last year, DuPont Industrial Biosciences was awarded a grant from the European Commission to demonstrate high-efficiency enzyme production to increase biogas yields as part of the DEMETER project. DuPont is proud to be a partner in DEMETER and to apply our decades of experience in the global industrial enzyme business to supporting the continued growth of the biogas sector in the European Union and around the world. DEMETER – supported in part by the work DuPont is undertaking through this grant – will demonstrate the power of enzymes to improve biogas yields and process robustness, ultimately increasing revenue and profitability for biogas producers in Europe. Funded through the Bio Based Industries Joint Undertaking under the European Union’s Horizon 2020 Research and Innovation program, DEMETER includes expert partners from across the entire biogas value chain, including: DuPont Industrial Biosciences (enzymes); Miavit (biogas ingredients distributor); BioBase Europe Pilot Plant (upscaling); OWS (anaerobic digester expertise); DBFZ (biogas research centre); Ciaotech (economic and environmental evaluation); and Biomoer (biogas farm).

Reducing biogas production costs The specific objectives of DEMETER are to increase yields of the industrial biogas fermentation process by at least 20 per cent, and reduce the overall enzyme product cost by at least 15 per cent, while simultaneously increasing the productivity of the biogas production process. DuPont Industrial Biosciences will concentrate on reducing enzyme production costs by at least 15 per cent through demonstration field trials focused on showcasing the improved production efficiency that can be realised using high quality enzymes. Currently, DuPont enzyme technology can provide a reduction in production costs of up to 10 per cent.

The project is expected to be completed over the next three years. Through this grant, DuPont will demonstrate how enzymes can help to increase biogas production in shorter cycles and with higher quality output, and reduce agitation costs for biogas producers. Enzymes can break down cellulosic fibres and protein-rich materials, enabling faster fermentation times and biogas production at a lower cost. This will lead to increased biogas production from the same amount of feedstock, or decreased feedstock consumption to achieve the same level of biogas production, saving money and improving efficiency for biogas producers.

Advancing the biogas industry In addition to offering a new source of renewable energy to end consumers, improved biogas production also offers important environmental benefits. Enzymes can create biogas from any organic material that contains cellulosic fibres, including agricultural materials, as well as farm, animal, paper and food wastes. This includes enabling the safe use of non-food feedstocks such as straw and deep litter muck to create biogas. Increasing yields is an important area that must be explored to improve plant economics for new developments in the already prolific European biogas market. In parallel, there is much room for improvement, and we believe that high quality enzymes are key to unlocking better results for the existing biogas industry, as well as for new AD facilities. We are excited to apply our expertise in enzymes to the challenge of expanding and improving biogas production in the European Union through the DEMETER project – an important market-driven, bio-based solution that will help meet the energy needs of a growing population, while protecting the environment for future generations.

Safety First Occupational health considerations for workers in contact with bioaerosols By Toni Gladding, Senior Lecturer in Environmental Engineering, Open University Bioaerosols have been in the news a lot recently, particularly with the Environment Agencyâ&#x20AC;&#x2122;s release of M9 (environmental monitoring of bioaerosols at regulated facilities). But what are they and why are they important? Bioaerosols are airborne microorganisms. These are commonly produced by many natural and human activities and are always in the air around us, but large numbers can be released from biological waste treatment. Bioaerosols include live bacteria and fungal spores, as well as components such as endotoxin (from the cell walls of certain bacteria). They can cause infectious, allergic or toxic effects in people who are exposed to them. People working at waste management facilities may inhale large quantities of bioaerosols, particularly during activities such as compost turning, during maintenance of waste treatment equipment, or during tipping indoors. Effective COSHH assessments identifying areas of risk and measures should be taken. Practically, those working at a plant can be protected by restricting access in

areas where high concentrations are present, good ventilation or filtered vehicle cabs or respirators, in accordance with recognised health and safety practice. Strict hygiene measures for working in facilities are also recommended. There are no workplace exposure limits for bioaerosols because methods of measurement are not standardised and health data is not available. However, concentrations over 105 cfu/m3 (colony-forming units, eg culturable units) are considered elevated. For endotoxin, there is an occupational limit in the Netherlands of 90 EU/mg3, which has been exceeded in UK facilities. However, research is still unclear and we do not know if there are any long term health effects from these kinds of levels. Nevertheless, it is important to note that there have been occupational issues here in the UK from exposure to bioaerosols, so assessing the workforce is recommended. The Waste Industry Safety and Health Forum (WISH) is currently drafting health surveillance and bioaerosols guidance to assist the industry in evaluating this risk. ADBA is pleased to represent the AD industry in WISHâ&#x20AC;&#x2122;s work on bioaerosols and will be letting members know how to get involved. Contact to find out more.

Membership Matters Members debate industry’s future

TEAM Chief Executive, Charlotte Morton T +44 (0)203 176 0503 E

With the general election announcement coming just days earlier, our spring Members’ Meeting proved a timely opportunity to reflect on the industry’s achievements so far this year, and look towards what the rest of 2017 and beyond could bring.

PA to Chief Executive/Database Assistant, Priya Gathani T +44 (0)203 567 1041 E Strategic Adviser, Chris Huhne E Head of Policy, Ollie More T +44 (0)203 567 0751 E Policy Officer, Thom Koller T +44 (0)203 176 0592 E

Held at the offices of Ashurst LLP in the heart of London on 19 April, attendees heard from Chris Huhne, ADBA’s Strategic Adviser, on what Brexit could mean for AD. In his hastily rewritten speech, Chris ventured that, while a strong mandate for Theresa May in the election could help her to get her policies through parliament more easily, a landslide victory for the Tories could radicalise Scotland. “Watch out for Scoxit,” he warned. Chris also remarked upon Theresa May’s determination to go for a hard Brexit but reminded members that, with 27 countries making up the rest of the EU, there would need to be 27 agreements on every single change she proposed, meaning the likelihood of anything happening overnight was slim. Chris felt this could benefit the UK in long run, stating: “The longer the Brexit transition, the better for the UK economy.” Members also heard from BEIS’ Harriet Arscott and Ofgem’s Luke Bailey on the latest regarding the FIT and RHI respectively. Much to our members’ disappointment, there was no light at the end of the tunnel regarding the future of the FIT, with the queue currently stretching back around one year. “Could we see the last generator applying for the FIT in Q1 of 2018?” proposed ADBA’s Head of Policy, Ollie More. Discussions on transport, green gas trading and ADBA’s Best Practice Scheme proved enlightening, while ADBA’s PR & Parliamentary Affairs Executive Chris Noyce and External Affairs Manager Jon Harrison outlined their plans to challenge the perceptions of AD in both the national and local press, and build relationships with key politicians and stakeholders. “We are working towards ADBA having at least one engaged MP in each key government department,” stated Jon, who added that he and Chris were ready to go ‘policy speed-dating’. Following a market update by Ollie More, Chris Huhne brought the afternoon to a close with a lively and engaging debate on the future of the industry – where it’s heading versus where it should be heading. Many audience members – including Schmack Biogas’ Oliver Vigano, ADNet’s Angie Bywater, AcrEnergy’s Daniel Scheven, and R J Upton Trading’s Robin Upton – participated in the discussion, which covered issues such as peak lopping, biogas storage, heat usage, food waste collection and grid capacity. 58

Co-located shows

Delivering the UN SDGs Anaerobic digestion and biogas is one of the only sustainable energy sources which can directly satisfy as many as nine of the UN’s 17 Sustainable Development Goals whilst recycling waste and delivering vital energy and food security. This July in Birmingham, we are delighted that the UK AD & Biogas trade show will return for its 7th edition, this time in partnership with the World Biogas Association to create the UK AD & Biogas and World Biogas Expo 2017 which will bring the global community together to discuss what needs to be done to ensure AD can deliver its crucial contribution to the UN Sustainable Development Goals.








This event will look at the potential of the industry, the research that could deliver the step change needed to make biogas cheaper than coal at a scale bigger than nuclear, the global market opportunities, the latest improvements in operational performance and biomethane production and use in heating and transport.


With global recognition of the technology’s potential gaining ground, we have secured a fantastic line up of speakers from international institutions to share their views on these critical issues, including representatives from: the International Energy Agency, the Global Methane Initiative, the USA’s Environmental Protection Agency, the International Solid Waste Association (ISWA), Italy’s CIC, Brazil’s Universidade Federal de Minas Gerais, Greece’s National Technical University of Athens, the World Biogas Association, as well as the UK’s new London Food Board, WRAP, Zero Waste Delivery, Scottish Government and the National Farmers Union (NFU). For more information, please see the full programme on our website Find out who is leading the way in AD and biogas, meeting targets for business performance, best practice and sustainability goals. What are the best international markets for AD and what are the economic models behind them? What challenges are we facing as a sector, such as the impact of Brexit, and which countries are already including biogas in their strategies for meeting global climate change targets and UN Sustainable Development Goals? With 4,000+ attendees from 50+ countries, over 57 hours of content across the conference and two seminar rooms, the Research and Innovation Hub, 250+ AD exhibitors, the co-located BioBased Innovations and Wastewater & Sewage Treatment Expos, the AD and Biogas Industry Awards, workshops, three AD plant site visits and much more besides, this event is the global hub of the AD and biogas industry and is not to be missed!
