ADBA gives direct support to AD operators, plant managers, plant owners and developers. We provide our own expertise and facilitate collaboration amongst experts, officials and peers. For more details and to get involved, contact

Free Information Sessions

We organise group meetings in-person locally where possible and online for local and national audiences. Experts present on latest trends and analysis. We encourage operators to ask questions and troubleshoot with regulators, ADBA staff and each other prior to, during, and after the event. Be sure to check our events listings regularly. Or sign-up to our mailing list.

Site Visits

Our team travels to AD plants around the UK and overseas to exchange best practice and develop relationships.

Networking with Services and Suppliers

ADBA matches operators with service providers, product suppliers and feedstock suppliers. Operators can proactively search through our membership lists. We also set up events, such as our annual World Biogas Expo, where suppliers exhibit their ware and foster relationships, and we manage a “Feedstock Finder” service.

Working Groups

We gather operators to tackle industry issues and promote their voice to policymakers. For each topic, we assemble a Working Group, such as: Agriculture; Food Waste; Digestate; Biomethane-to-Grid; Training, Safety and Environment Management (TSEM); and Water.


ADBA’s network of experts put on courses on the latest and most salient topics, such as digestate, health & safety, plant optimisation, clamping and feedstocks.

Best Practice

ADBA founded the Anaerobic Digestion Certification Scheme (ADCS). This is unique in that it assesses the all-round safety, environmental and operational performance of AD plants. It encompasses all our work on improving standards in the industry and ensuring best practice.


The AD sector has tremendous potential for carbon abatement in the hardest to decarbonise sectors. On behalf of AD plants, ADBA lobbies to Government for subsidies in heat, electricity and transport.


Our specialist team dissect the latest regulations, ensuring our members understand and comply. We also gather member insight to influence regulatory consultations.


AD operators and developers, institutions and local governments open up projects for our members to bid for business.


By gathering and anonymising data, we create snapshots of industry trends and forecasts. For example, we are currently collating and analysis a range of digestate data and can benchmark participants submissions against our data.

The AD Certification Scheme (ADCS) is the only certification scheme in the UK that assesses the all-round safety, environmental and operational performance of anaerobic digestion (AD) plants. It is a key element of ADBA’s best practice programme, which encompasses all our work on improving standards in the industry. The Scheme provides an independent audit process and report, which is a useful tool for operators to ensure they are meeting required standards and identify how they can improve. Developed by ADBA with extensive engagement with industry stakeholders, it aims to support the industry to be a mature, safe and thriving sector that delivers consistently excellent projects and continued professionalism.

ADBA’s network of experts put on courses on the latest and most salient topics. Here are examples of our recent training and Learning & Development events, many of which are run annually:


In this Learning & Development event, attendees  considered how digestate is more than an inevitable by-product of the anaerobic digestion process. Really, it can be turned into an asset that can cut costs and even drive profits. The group found out about digestate uses, effects on soil, land-banking, enhancement technology, appeal to farmers, agronomy, post-harvest applications, regulations and ammonia emissions. Attendees heard directly from industry experts and learned from case studies.

Health and Safety

This training course was designed specifically for AD plants and intended to cover all key areas of plant Health and Safety. It included hazardous substances; machinery and equipment; electrical safety; transport safety; people and training and much more, — plus an understanding of the legislation and regulations that need to be adhered to.

It was ideal for any and all operatives and staff involved in the AD process, and many AD plants in the UK provide this course to all their staff as part of the induction process. A certificate was issued to all attendees that completed the course.

Plant Optimisation

This training was aimed at anyone interested in improving their knowledge and understanding of the AD process, in order to increase output and process stability. It was about getting the most from your AD plant, by understanding, monitoring and finetuning the processes involved. This was to help minimise problems and downtime.

It was appropriate for all operators, owners, managers and anyone involved in the AD process.


This Learning & Development event addressed the whole process of clamping, from planning and monitoring feedstock, to filling and covering effectively, safely working the clamp, to emptying/feed-out dos’ don’ts and special equipment. The event also addressed contract management and environmental issues.

Feedstocks and Coronavirus

During coronavirus surplus production and novel waste streams became available for the AD industry. Our course explained issues with accepting these feedstocks and why they have arisen. We also gave advice on what to do if your feedstock has decreased. With AD a central part to the circular economy and waste hierarchy it is pivotal for processing organic streams that cannot be used for human consumption or animal feed. Our farming, academia, AD consultants and regulator speakers from our full training days explained where, what, and how this will impact optimisation including biochemistry, heating, energy generation and digestate.

Recent Training and “Learning & Development” Events…

Health and Safety Essentials

Agri-feedstock and Clamp Management Day

Training: Temperatures and Biology

We gather operators to tackle industry issues, find out the latest developments in the sector and directly influence government policy and regulation. For each topic, we assemble a Working Group. These can be either AD operators only or open to operators and suppliers or open to certain disciplines, such as finance. Officials attend some Working Groups sessions, for example from BEIS, Defra, EA, HSE and WRAP.

Agricultural Operator Group

The ADBA Agricultural Operator Group is a meeting of AD operators using crop and agricultural feedstocks, and is the central platform in the UK for operators to discuss issues affecting them, and to shape and share information on areas including policy, best practice, health & safety, training, agronomy and AD developments more widely. The Crop Operator Group is now integrated into this group.

Chair: Innes McEwen, Head of Farming, Future Biogas

For more information about this Group, and other Operator Groups, please contact

Food Waste Operator Group

The ADBA Food Waste Operator Group is a meeting of industry leaders and food waste operators designed to support and help promote the value, benefits, and best practice of food waste to a wider audience. The Food Waste Operator Group is the central platform for the industry to discuss key issues such as BREF (BAT Reference Document) regulations, end-of-waste criteria and market based issues including gate fee prices. This group helps ADBA develop policy positions which directly influence government decisions.

Chair: Kevin Quigley, Commerical Director, Warrens Group

If you wish to find out more about the Food Waste Operator Group and how to get involved, please contact

Finance Forum

The ADBA Finance Forum is an informal bi-annual meeting of industry leaders, stakeholders and other interested parties focusing on the challenges facing the AD sector in terms of finance, government subsidies – including Feed-in-Tariffs (FITs) and the Renewable Heat Incentive (RHI) – and the priorities for the industry to help prevent the slow-down in growth of small scale AD developments.

If you wish to find out more about the Finance Forum and how to get involved, please contact Cheryl Murdoch at and +44 (0) 20 3176 0503.

Biomethane to Grid Working Group

The Biomethane to Grid WG works on the barriers to upgrading biogas to biomethane and injecting it into the gas grid. This includes current gas grid specification for biomethane injection and proposed changes, and the wider regulatory framework (with BEIS, Ofgem and HSE). The Group will also work on assessment of biogas upgrade technologies, best practice for upgrading biogas to biomethane and issues surrounding the sale of injected biomethane and the Renewable Heat Incentive (RHI). Representatives from BEIS’s and Ofgem’s RHI team have also attended meetings, allowing members the opportunity to directly influence future changes to how the RHI will support biomethane injection.


Training, Safety and Environmental Management (TSEM)

The Training, Safety and Environment Management WG acts on all aspects of health and safety and training for AD. This has included work with CIWM and EU Skills, both of whom send representatives to the group’s meetings, to develop a training matrix for future needs for the industry. Draft decision trees for training provision and competences are being developed and will commence a review to identify the need for developing accredited training programmes to cover induction, underpinning knowledge and skills training. The HSE are also part of the group, and update members on their latest developments, as well as answering questions.

Chair: David Woolgar, Biogen

The Transport WG aims to bring together the key stakeholders – and potential stakeholders – in the biogas-to-biomethane upgrading sector for use in vehicles. This includes Local Authorities, vehicle manufacturers and commercial organisations. The development of gas refuelling infrastructure is a key issue for the group, with the group playing a central role in the Defra-funded construction of a database of gas refuelling infrastructure which Greenwich Council is leading. It leads the development of ADBA’s strategic vision for biomethane in transport, and supports the Association’s lobbying for policy change to support this sector.

Chair: Andrew Whittles, Low Emission Strategies

Innovation is vital to delivering a financially sustainable AD industry, bringing down the cost of deployment and increasing revenue from AD’s co-products. It stands to advance all aspects of the AD industry, maximising its environmental benefits, while also investing in projects which support the collaboration of multi-disciplinary teams such as academia and industry.

Research Grants

ADBA maintains a database of research councils and institutions to fund research grants. We can give you key contacts and help you write your proposals.

Government Funding

ADBA recommends that the government creates a new fund specifically dedicated to research supporting AD and its production of biomethane and digestate. To encourage applied research, funding applications can target key aspects of the AD industry and be carried out simultaneously rather than sequentially to speed up success rates. This holds the potential to significantly improve the AD industry’s financial model and the socio-economic benefits delivered. With sufficient support, innovation could eliminate the industry’s dependence on government financing and move towards its full potential – treating all organic wastes and extracting maximum value from them. And ultimately, research and innovation are effective means of increasing value for money to the taxpayer.

Connecting Academia and Industry

Our team aims to speed up AD technology’s transition from academia to industry – and with it, its commercial value. This enables operational plants to trial new solutions, without significant risk to their annual operations.

International Markets

Through innovation and development, the AD industry can bring technologies up to the technology-readiness-levels (TRLs) and converting knowledge into new commercial opportunities. For instance, once commercially viable, innovations may also be exported to international markets, strengthening the UK’s place in the world – globally, AD is only achieving 2% of its full potential.

Realising the green premium for biomethane producers

Green Gas Trading Limited (GGT) offers both a secure, credible process for certifying biomethane and a platform to facilitate the trading of certificates to maximise the value of this ultra low carbon fuel, at a market determined price.

The Biomethane Certification Scheme (BMCS) certifies biomethane whether it is injected into the gas grid, liquefied or compressed.

How does it work?

The Biomethane Certification Scheme issues Biomethane Certificates (BMCs) that also called green gas certificates and RGGOs in the market. The BMCS registers certificates with GGT in the name of the producer. The BMCs represent the green (or ‘bio’) element of the biomethane produced rather than the physical gas and, critically, do not follow the contractual flows of the physical gas, which is transacted separately. By divorcing the green element from the physical gas, both products can be traded/sold independently allowing the producer to obtain the highest value for both the physical gas and the ‘green credentials’ of this premium product.

Scheme Information

The certificate market can generate revenue and benefits for the producers, traders, and end-consumers. The GGT website provides information on the benefits BMCs provide to producers, consumers, and the UK as well as explaining the process for all parties.

The BMCS website, hosted by GGT provides:

  • a tendering page for buying and selling surplus certificates
  • a list of current producers, traders, and suppliers.
  • information on certificate use and Green Gas Trading’s Biomethane Certification Scheme (BMCS)
  • member-only access for viewing quarterly reports and uploading tender
  • joining and scheme fees
  • example certificates
  • information for support with the Grexel registry
