INDIAN GEOGRAPHY

Detailed explanation-1: -Biogas typically refers to a gas produced by the biological breakdown of organic matter in the absence of oxygen. Organic waste such as dead plant and animal material, animal feces, and kitchen waste can be converted into a gaseous fuel called biogas.

Detailed explanation-2: -When biodigesters are fed organic material-food waste, agricultural residues, and animal or human manure-it is decomposed by microorganisms in the absence of oxygen and turned into biogas, which can then be used for heating, cooking, transportation and other needs.

Detailed explanation-3: -Preparation of the input material. Digestion (fermentation), consisting of hydrolysis, acetogenesis, acidogenesis and methanogenesis. Conversion of the biogas to renewable electricity and useful heat with gas engines. Post-treatment of the digestate.
