Waste Management

Choose the Correct Answer

Correct Answer : Option a

Explanation
Statement 1 is correct: Biocomposting is a method of composting that uses microorganisms such as bacteria and fungi to break down organic waste (like food scraps, garden waste, etc.) under controlled conditions (temperature, moisture, and oxygen) to create compost, which can be used as a soil amendment.

Statement 2 is correct: Vermicomposting is a type of biocomposting that specifically uses earthworms to decompose organic material. The earthworms break down the organic matter and produce rich, nutrient-dense compost known as worm castings.

Statement 3 is not correct: Biocomposting, when done properly, is an aerobic process (requiring oxygen), and it does not typically release methane in significant amounts. Methane is primarily produced in anaerobic conditions (without oxygen), such as in landfills or when organic waste is decomposed in the absence of oxygen. Well-managed composting systems do not produce large amounts of methane, and instead, they release carbon dioxide, which is much less harmful in the context of global warming.
