Welcome to the Wales Centre of Excellence for Anaerobic Digestion.

Since 2008 the Wales Centre of Excellence for Anaerobic Digestion has been providing support and technical services to the AD industry, industry stakeholders, policy developers and regulators. Our aims are to facilitate the development of a robust anaerobic digestion infrastructure within Wales, to foster innovative solutions that maximise the environmental and economic benefits of the process and products, and to encourage long term growth of the industry.

The Wales Centre of Excellence for Anaerobic Digestion is based in the Sustainable Environment Research Centre (SERC) at the University of South Wales in Treforest, South Wales. The Centre is funded by the European Regional Development Fund (ERDF), the Welsh Government (WG) and the University of South Wales.

This website should be considered as a first port of call for AD information. The site will evolve and be updated over time and we will be keeping you up to date with developments in the AD industry in Wales and the UK as they happen. If you require additional information, please do not hesitate to contact the AD Centre directly using the Contact facility.

What is Anaerobic Digestion and why should it be encouraged?

Anaerobic digestion is the conversion of biodegradable material in sealed vessels in the absence of oxygen by a consortia of bacteria from which a valuable biogas is produced. This biogas is collected and utilised as a source of energy. A digestate also results from the process that can be utilised as a fertiliser (replacing mineral fertiliser) and as a soil conditioner.

AD has already been implemented across many countries in Europe to treat biodegradable organic wastes such as source segregated food waste, organic fraction of municipal solid waste (OFMSW), biodegradable commercial and industrial (C&I) wastes, sewage sludges, agricultural residues and animal slurries as well as to generate energy from energy crops. The UK has already seen a significant deployment of anaerobic digestion technology for treating sewage sludge and some progress is being made recently in the establishment of this technology for treating other organic materials.

Anaerobic digestion is an attractive option for Wales and the UK as it can contribute towards meeting targets for waste recycling and diversion of organic wastes from landfill, the requirement to pre-treat organic materials prior to disposal, targets to reduce greenhouse gas emissions and the requirement to generate renewable energy.
