Gobar gas is primarily made up of___________________?
Show answer Hide answer
Answer: A. CH4 & CO2
Explanation
Anaerobic digestion of organic waste generates biogas consisting primarily of methane and carbon dioxide. Methanogenic bacteria break down complex organic molecules into simple gaseous products. Methane provides the combustible energy while carbon dioxide acts as the secondary diluent. Gobar gas production utilizes wet cow dung fermented in sealed underground digester pits. Typical biogas compositions range from fifty-five to seventy percent methane gas. The remaining volumetric fraction consists mostly of carbon dioxide with trace impurities.
Rural communities use gobar gas for domestic cooking and lighting applications. Anaerobic digestion converts agricultural waste into clean energy and rich organic fertilizer. This decentralized renewable technology reduces reliance on firewood and fossil fuels. Carbon monoxide is toxic and is not a primary component of anaerobic biogas. Nitrogen is present in trace amounts but does not dominate the gobar gas mixture. Option combinations lacking methane fail to reflect the combustible nature of biogas.
