What is Biogas? Biogas is created when bacteria degrade

biological material in an anaerobic state, or the absence of oxygen

Biogas is a clean fuel produced from anaerobic digestion

Biogas is comprised of 55-65% methane, 35-45% carbon dioxide, 0.5-1.0% hydrogen sulfide and other traces of water vapor

Biogas is corrosive in nature making it difficult to store

Why Biogas?By harnessing biogas, various

types of energy can be produced Power has become a major

concern in rural regions of third world countries

Sanitation problems exist in every population, and digesters offer a healthy solution
