Question

name the
major components of biogas and write the raw material used for making biogas ???

Answer 1

The major constituents of biogas are methane (CH4, 60 percent or more by volume) and carbon dioxide (CO2, about 35 percent); but small amounts of water vapour, hydrogen sulphide (H2S), carbon monoxide (CO), and nitrogen (N2) are also present. The composition of biogas varies according to the biological material. The methane content of biogas produced from night soil (human excreta), chicken manure and wastewater from slaughter house sometimes could reach 70 percent or more, while that from stalk and straw of crops is about 55 percent

Agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. are used for making bio gas

Answer 2

One type of biogas is produced by anaerobic digestion or fermentation of biodegradablematerials such as biomass,manure, sewage, municipal waste, green waste, plant material andenergy crops.

These plants can be fed with energy crops such as maize silage or biodegradable wastes including sewage sludge and food waste.
