What is biogas anyway? Biogas typically refers to a (biofuel) gas produced by the anaerobic digestion or fermentation of organic matter incl. manure, sewage sludge, municipal solid waste, biodegradable waste, biodegradable feedstock, renewable raw materials under anaerobic conditions. 11.02.2009 9 Hese Biogas GmbH
Typical composition of biogas Methane, CH4 50-75% Carbon dioxide, CO2 25-50% Nitrogen, N2 < 2% Hydrogen, H2 <1% Hydrogen sulphide, H2S 0-3% Oxygen, O2 <2% 11.02.2009 10 Hese Biogas GmbH
