    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.

    We gather stakeholders 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. Interested in joining? Fill-in the form below.


    Carbon Intensity of Biogas working group

    Strategy segments: Policy and Technology

    Description: As the UK strives to net zero, there is a growing demand from both public and private sectors to demonstrate any carbon savings delivered. Considering AD’s ability to decarbonise across multiple sectors, this working group will explore how these sources of carbon savings may be attributed to biogas and quantified within the fuel’s carbon intensity (CI). If the heat and transport sectors are to meet their decarbonisation goals, the CI of energy used must be considered. The market for BMCs already reveals that biomethane with lower CIs command higher prices. This valuation is forecast to increase further, presenting a critical opportunity for biogas to shake its dependence on subsidies.

    Suggested aims:

    • To discuss methodologies used to calculate CI of biogas (e.g. REDII, LCFS)
    • To explore how CI is current valued in the voluntary and compulsory markets, and how this might change in the future
    • To assess risk of double counting carbon savings and identify ways of preventing it from occurring
    • To establish if and how bio-CO2 utilisation and storage may affect the CI of biogas
    • To better understand the CI of bio-hydrogen (with/out CCS) and its potential role in net zero

    Suggested deliverables:

    • Assessment of the methodologies used to calculate CI of biogas, identifying all factors considered and their relative impact on CI
    • Establish a range of carbon intensities expected from different feedstocks (low / average / high)
    • Identify cost effectiveness of production utilising feedstock costs and carbon/energy prices
    • Develop infographic displaying key findings and present to BEIS and DfT

    Expectations: Project plan, to be responsible to making sure everyone sticks to tasks and timeframe


    Food Waste working group

    Strategy segments: Standards and policy

    Description: We are at a pivotal moment of waste policy with the imminent release of the outcome of the consistency consultation and the rollout of separate food waste collections. The industry faces a number of challenges as part of this rollout, including regional capacity levels, concerns around feedstock security in conjunction with the GGSS timeframe, and a need to reduce plastic contamination in digestate.

    Suggested aims:

    • To facilitate industry response to the rollout of separate food waste collections
    • To address capacity concerns and facilitate industry response to separate food waste collections for the benefit of the AD industry so as to not promote over development leading to unfavourable market conditions
    • To facilitate valorisation of digestate by tackling one of the key factors inhibiting its uptake – plastic, and work towards the elimination of plastics being spread to land via digestate
    • To disseminate developments in understanding on plastics contamination and understand the implications for the industry
    • To coordinate ADBA’s response to food-waste policy consultations
    • To identify and promote best practise from across the industry, highlighting strong local authority/operator relationships and technological best practise
    • To tackle front-end contamination through cross-party collaboration
    • To help deliver ADBA’s contribution to WRAP’s Organic Roadmap
    • To mobilise funding to enable plants to install technologies to remove plastic contamination

    Suggested deliverables:

    • Contribute to the WRAP Organics Roadmap obligations i.e., develop guidance for waste collection operators maintaining quality for commercial food waste collections
    • Communication of any relevant developments in scientific understanding of plastics
    • Publication of an ADBA position on compostable and biodegradable packaging (e.g., in line with the Plastic Planet report and requirements under the WRAP Organics Roadmap)
    • Development of a repertoire of best-practise case studies where operators, businesses, local authorities, and waste producers have worked together to drive best-practise
    • Submit a proposal to BSI for the development of a digestible standard


    Small On-Farm AD working group

    Strategy segments: Policy, commercial and technology

    Description: The potential of the on-farm AD industry is substantial, with over 90Mt of manures and slurries and a potential 3.6Mt of pre-farm gate crop-residues available to send to AD. In doing so, significant amounts of methane can be abated while producing renewable energy to be used both on and off-grid. Despite this potential, there are significant barriers to the development of small on-farm AD and the uptake remains relatively low due to the technological and economic barriers.

    Suggested aims:

    • To develop a core set of policy asks to remove the barriers to taking up small scale on-farm AD
    • To address the technological gap on on-farm AD solutions
    • To facilitate a reduction in the capex and opex of small on-farm AD to make it more financially viable

    Suggested deliverables:

    • Produce a set of policy asks to create more favourable conditions uptake of small-scale AD development
    • Submit a proposal to BSI for the establishment of a small-scale AD standard to ensure farmers have confidence in such technologies


    Sustainable Bioenergy Crops working group

    Description: The Committee on Climate Change’s Sixth Carbon Budget report estimates that 260,000 hectares of agricultural land will need to shift support bioenergy production alongside carbon capture storage (CCS). Despite the recognised place for bioenergy crops in the CCC’s Budget, concerns about bioenergy crops remain at the fore, and can be a barrier to industry development. The food versus fuel debate is a contentious, yet important one given the impending food crisis, as are the impacts of poor land-management on biodiversity.

    Suggested aims:

    • To determine what a “sustainable bioenergy crop” looks like
    • Updating guidance and informing the industry and public on what constitutes sustainable bioenergy
    • Address the food versus fuel debate
    • Address Defra’s concerns on unsustainable bioenergy crops farming practices

    Suggested deliverables:

    • Update the Good Crop Guide
    • Create position paper on ADBA’s support for sustainable bioenergy crops
    • Collate a central repository for evidence on sustainable bioenergy crops
    • Develop the figures on what could be considered a suitable volume of energy crops


    Wastewater working group

    Strategy segments: Policy and commercial

    Description: The wastewater sector spearheaded the development of AD in the UK, and it remains a significantly strong part of the sector. While uptake of AD is strong across the sector, there are a number of regulatory developments – namely driven by the EA and Ofwat – in progress that aim to shake-up the market.  This working group seeks to strengthen the collective voice of the industry while opening the dialogue between water companies and third parties.

    Suggested aims:

    • To create an open dialogue between water companies and the wider AD industry at a time where the regulator is trying to develop the sector
    • To discuss Ofwat’s plans to introduce bid assessment frameworks and co-ordinate industry responses to water and sewage companies’ BAF consultations
    • To provide feed-in to ADBA’s response to relevant consultations

    Suggested deliverables:

    • To develop an ‘ideal’ template standard for a bid assessment framework agreed between the water industry and potential third parties
    • To facilitate a coordinated response to the introduction of Bidding Assessment Frameworks by providing water companies the opportunity to engage directly with interested AD community members by presenting their BAF consultations

    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
