Production of gobar gas stems from the _______________ of cow dung ('gobar') ?

Select your answer for: Production of gobar gas stems from the _______________ of cow dung ('gobar') ?
Show answer

Answer: B. Fermentation

Explanation

Biological fermentation of organic waste inside cow dung generates gobar gas. Anaerobic bacteria convert complex carbohydrates into methane and carbon dioxide. This fermentation process proceeds steadily under warm moisture conditions. Gobar gas digesters maintain an oxygen-free environment for specialized bacteria. Cow dung contains rich organic matter and active microbial populations. Gas production peaks within optimal temperature ranges typical of tropical climates.

Farmers use biogas plants to convert livestock waste into cooking fuel and fertilizer. This waste-to-energy approach promotes rural sanitation and sustainable living. Biogas systems reduce greenhouse gas emissions compared to untreated manure decay. Hydrolysis is only the initial breakdown step before full anaerobic fermentation occurs. Oxidation destroys organic matter with oxygen and fails to produce combustible methane. Dehydration removes water and halts the biological reactions needed for biogas generation.
