1242: Farm anaerobic digestion

This paper is summarised from Rural Economy and Land Use, Policy and Practice Note 26 ‘Farm diversification into energy production by anaerobic digestion’

Year of Publication2011

Anaerobic digestion on farms can provide additional income through using the biogas to generate electricity and heat, or upgrading it to a transport fuel. This contributes towards renewable energy targets, with the option of using the energy to supply the local community. It also offers environmental benefits by reducing greenhouse gas emissions associated with farming, and promotes the recycling of nutrients which can be used in place of artificial fertilisers. The process can use waste biomass, manures, slurry and energy crops and, by careful planning and adaptive land use, can maximise the use of the whole crop for food and energy.
