Biogas fact sheet, 2015. Global Alliance for Clean Cookstoves.
Biogas is a methane rich gas produced through the anaerobic (without air) digestion of organic wastes. It can be generated from animal and kitchen wastes, as well as some crop residues. For cooking and other thermal household tasks, biogas can be used directly in conventional low-pressure gas burners.
Biogas is used for many different applications worldwide. In rural communities, small-scale digesters can provide biogas for single-household cooking and lighting. Large-scale digesters can utilize biogas for electricity production, heat and steam, chemical production, and vehicle fuel.
