Anaerobic digestion (AD) is a proven, well-tried and tested technology that converts organic matter to biogas in the absence of oxygen. Feedstocks for AD include sewage, animal manures, agricultural crops, animal by-products, organic wastes from industry (mainly from food processing) and the organic fraction of household waste. Within agriculture, AD is currently carried out on-farm, or in larger centralised AD plants. This research is concerned with on-farm AD.
On-farm AD has potential to produce biogas as a renewable fuel and to assist in managing the plant nutrients in slurry. At present information on the performance and economics of on-farm AD in Northern Ireland are unknown. In order to provide this required information, the Agri-Food and Biosciences Institute at Hillsborough is installing an on-farm anaerobic digester. Data gathered from this research project will provide much needed information for the industry.
