Anaerobic digestion is the most widely process used for the stabilisation of wastewater treatment sludge. Organic matter is transformed into CH4 and CO2 by the action of different bacteria groups. The main advantages are the reduction of the volume of waste sludge and the production of methane gas that can be utilized as energy supply for the process.
