A solid waste management practice which refers to the controlled decomposition of organic matter by microorganisms, mainly bacteria and fungi, into a humus-like product.

• A. Recycling
• B. Bioremediation
• C. Composting
• D. Reducing

Answer: (C)

The main concept here is the controlled decomposition of organic waste by microorganisms into a humus-like product. This is composting, where bacteria and fungi break down organic matter (like food scraps and yard waste) under managed conditions—adequate moisture, aeration, and the right carbon-to-nitrogen balance—to produce a stable, humus-like material that can improve soil structure and fertility. This differs from recycling, which reprocesses materials into new products rather than decomposing organic matter. Bioremediation uses microbes to clean up pollutants in the environment, not to produce soil amendments from general waste. Reducing aims to lower the amount of waste generated in the first place rather than processing it.
