Biogas is a methane rich gas produced through the anaerobic digestion (ie. without air) of organic wastes. It can be generated from cattle dung and animal wastes, and with substantially more difficulty, from some crop residues. Although these feedstocks are frequently used directly as cooking fuel, in most areas they are not preferred fuels and are used only when wood is not available.

Biogas systems offer multiple benefits. The digester-effluent is usually a good fertiliser, and, if connected to latrines, biogas plants can provide valuable sanitation services. For cooking and other thermal household tasks, it is simple and reasonably efficient to use the gas directly in conventional low-pressure gas burners. Biogas can also provide lighting when used in mantle lamps. In societies where suitable feedstocks are readily available, small family-sized biogas digesters were thought to have considerable potential.

A example of a video created by SNV, the Netherlands Development Organisaiton, who have been supporting the formulation and implementation of national programmes on domestic biogas since 1989, shows the principles behind the technology.
