Report on Bio Gas Plant SlideShare

Report On Bio Gas Plant Slideshare

Mar 09, 2014 Biogas is a type of biofuels created via anaerobic, or oxygen-free, digestion of organic matter by bacteria. A biogas plant is composed of a digester and a gas holder. The digester is an airtight container in which the waste is dumped and decomposed, and the gas holder is a tank that harnesses the gases emitted by the slurry.
