Biogas

Biogas commonly refers to a mixture of various gases formed by the disintegration of organic matter in the absence of oxygen. Biogas can be manufactured from raw matters  such as agricultural waste, municipal waste, manure, plant material, green waste, sewage or food waste. Biogas is a renewable energy source and in diverse cases exerts a limited carbon footprint. Biogas can be manufactured by fermentation of biodegradable materials or anaerobic digestion with anaerobic organisms, which disintegrates material inside an isolated system. Biogas is basically methane (CH₄) and carbon dioxide (CO₂) and may have small traces of hydrogen sulfide (H2S), siloxanes and moisture. The gases methane, carbon monoxide (CO) and hydrogen can be combusted or oxidized with oxygen. This energy yield allows biogas to be benefitted as a fuel; it can be utilized for any heating purpose, such as cooking. It can also be practiced in a gas engine to transform the energy in the gas to electricity and heat.
