Question

What is biogas? Write in brief about the production process.

Answer 1

Biogas is the mixture of gases (about 60% methane) produced by anaerobic bacterial digestion of organic matter. Biogas consists mainly of methane (CH4; ca. 60%) and CO2(ca. 40%) plus traces of hydrogen (H2) and several other gases. It is produced by anaerobic degradation of a variety of organic materials, ranging from simple sugars to polymers like cellulose and nucleic acids by a community of organisms.

Answer 2

Biogas is the gas that contains methane, ammonia and different components along with a lot of carbon dioxide.

Explanation:

• Biogas is produced mainly by decomposition of cow dung, vegetable peels and different other organic wastes that are decomposed aerobically to produce Biogas.
• For the production of biogas, organic wastes are dumped in a biogas producer which is a big tank. This tank then is filled with cow dung and thoroughly mixed and allowed to ferment.
• The methanobacteria that is there in cow dung ferments the organic matter to produce biogas. It is a fuel that can be used in low scales as cooking fuel, in boilers, etc.
