What is the main goal of composting in solid waste management?

The primary goal of composting in solid waste management is to enhance soil quality. Composting involves the decomposition of organic matter, such as food scraps and yard waste, through natural processes facilitated by microorganisms. This process produces compost, which is rich in nutrients, improves soil structure, increases moisture retention, and promotes healthy plant growth. By enriching the soil, composting not only aids in agricultural practices but also supports sustainable land management and reduces the need for chemical fertilizers.

While reducing waste volume is a benefit of composting, as it significantly diminishes the amount of organic material that would otherwise take up space in landfills, the overarching aim is to create a valuable soil amendment. Similarly, converting waste into energy, although a viable waste management strategy, does not capture the essence of composting, which centers around nutrient cycling and soil improvement. Lastly, while increasing landfill space may be a broader goal within solid waste management, it does not specifically represent the main objective of composting, which directly pertains to soil enhancement.
