EBNet Working Group: Anaerobic Digestion

Aim:

Small AD plant on dairy/free range chicken farm

Through its activities the WG will aim to engage stakeholders from trade bodies, industry, water utilities and government departments such as the EA, Defra, BEIS and others.

What’s Next for AD? – The EBNet Anaerobic Digestion Working Group

Current generation anaerobic digesters provide a sustainable and low-carbon treatment of organic waste and wastewater sludges using mature technology, with growth in the sector predominantly determined by the increased capture of AD-appropriate organic wastes. Despite this there remain exciting opportunities both in the improvement of existing AD processes and technologies (e.g. emerging feedstocks, pre-treatment, process intensification), and in the development of novel applications and new markets beyond the current AD status quo (e.g. biorefining/high value products, green hydrogen, biomethanation). The group will bring together relevant interdisciplinary expertise to explore ‘What’s next for AD?’ and how the wealth of historical and current research combined with existing expertise in this field can contribute to the next generation of anaerobic biotechnologies across the energy, food, agriculture, water and biomanufacturing sectors. The group will aim to strengthen the link between the AD research community, policy makers and industry to ensure activities support both near- and long-term industrial needs. Initially the group will act as a hub for collaboratively assessing the opportunities, challenges and barriers, with more specific outcomes developed through these scoping activities.

Contact the Working Group co-ordinator: Dr Mark Walker, University of Hull.

Mark is a lecturer in the Department of Engineering at the University of Hull and programme coordinator for the MSc Energy Engineering. Mark has over 10 years of research experience and has worked on 15+ academic and industrial innovation projects in the areas of bioprocessing, bio-based production, and bioenergy, with a particular focus on anaerobic digestion for waste and wastewater management and its integration into larger energy, biorefinery or agricultural systems. Mark’s research uses lab scale systems and process modelling to appraise and develop novel bioprocesses, to inform integrated models that can be used to design, analyse and optimise systems that involve combinations of technologies, and assess them against sustainability criteria using techniques such as technoeconomic assessment (TEA), carbon footprints and lifecycle assessment (LCA).

Relevant third party opportunities

Ukraine Energy Innovation Competition 

Do you have a low-carbon affordable, secure and innovative technology that could help Ukraine’s energy recovery?  Could your organisation work with Ukraine to create energy resilience to attacks in the short term or build access to clean energy in the future? Energy-related innovations are critical to Ukraine’s recovery and restoration. The Innovate Ukraine competition is open now. It supports businesses to develop highly innovative, sustainable energy technologies and business models which can specifically support the recovery of Ukraine’s energy system.

To help you find partners, a collaboration and networking platform is now live with details of the scope, eligibility criteria and support available to facilitate introductions.The scope is broad and your technology could be a game-changer in Ukraine. Full details and application route are only available via the competition site – here.
