Factsheet – Biogas Production via Anaerobic Digestion of Sewage Sludge and Co-Substrates
At wastewater treatment plants (WWTPs) with a capacity of 50 000 population equivalents and greater, anaerobic digestion is often used as sludge treatment. Therefore, excess sludge together with primary sludge and sometimes also with co-substrates such as fat, oil, grease, etc. is anaerobically digested and energy is recovered as biogas. Usually, the biogas is burned in a combined heat and power plant on-site in order to produce electricity and heat.
