Biogas is produced naturally by anaerobic bacteria in municipal solid waste landfills and is called landfill gas. Landfill gas with a high methane content can be dangerous to people and the environment because methane is flammable. Methane is also a strong greenhouse gas.

How biogas is produced?

Biogas is produced when bacteria digest organic matter (biomass) in the absence of oxygen. This process is called anaerobic digestion. It occurs naturally anywhere from the within the digestive system to the depth of effluent ponds and can be reproduced artificially in engineered containers called digesters.

Which is the main source to produce biogas?

Major sources of biogas include municipal wastewater treatment plants, industrial waste treatment facilities, landfills, and agricultural sources such as manure and energy crops.
