What is biogas?

Biogas is one of the most widely available biofuels in the world. This gas is produced anaerobically, primarily using biological waste material like sewage sludge, manure, solid waste from municipal dumpsites, agricultural wastes, etc. Energy crops and various types of wood can also be used to generate biogas.

The main components of biogas produced from waste matter are methane (75%) and carbon dioxide (25%). In the case of biogas produced in a wood gasifier, the major constituents include hydrogen, nitrogen, and carbon monoxide, along with trace amounts of methane.
