Biogas, resulting from the decomposition of organic matter, is known since the late 18th century: swamp gas. In Europe, the production of biogas on an industrial scale takes off somewhere between 1980 and 1990.
The report describes sources and processes for the generation of biogas: hermetically sealed waste dumps and the capture of biogas from anaerobic digestion; industrial anaerobic fermentation of household waste with different species of bacteria at different temperatures; fermentation of agricultural crop waste and animal droppings; processing of biodegradable sludge from waste water treatment plants; etc. Biogas plants using a second generation methanisation process at high temperatures have been built in Germany and Sweden. Biogas is regarded as a renewable energy but is not fit for industrial use in untreated form as it contains various contaminants that need to be filtered. The success of biogas as a substitute for natural gas depends on the financial incentives granted.
