Biogas is a mixture of gases that occur as a result of biological processes. Methane and carbon dioxide are the main components of biogas. Biogas is produced by fermentation of organic material such as manure or household waste. After this process, digestate remains. Marsh gas is a gas that naturally occurs.

Biogas as an energy source

Because biogas is biological, it is a sustainable energy source. The use of biogas is encouraged because methane has favorable combustion properties. The release of methane can be limited by using biogas.
