Anaerobic decomposition

Anaerobic digestion (AD) is the natural process of biological degradation of organic material in the absence of air. An anaerobic digester is a man-made system that harnesses this process to treat waste and produce biogas and anaerobic digestate, a soil-improving material. The biogas can then be converted into heat and electricity. Anaerobic digestion is widely used as a stabilisation process for the treatment of wastewater sludges and organic wastes. The process provides volume and mass reduction of the input material, whilst delivering valuable renewable energy. A biogas plant is an anaerobic digestion system that is designed and operated specifically for the purpose of producing biogas.
