What is one benefit of using biosolids in waste management?

Using biosolids in waste management offers a significant benefit as they can be used as fertilizer and soil amendments. This practice contributes to sustainable agriculture by enriching the soil with nutrients essential for plant growth, such as nitrogen, phosphorus, and other micronutrients. The organic matter in biosolids improves soil structure, enhances moisture retention, and promotes beneficial microbial activity, which can lead to healthier crops and reduced need for chemical fertilizers. Utilizing biosolids in this way also helps close the loop in waste management, transforming waste into a valuable resource while reducing environmental impact.

The other options highlight less beneficial or less sustainable approaches, such as incinerating for energy, which may not be as efficient or environmentally friendly compared to recycling nutrients, promoting harmful bacteria that can pose health risks, and primarily utilizing biosolids for landfill, which is not a productive use of these materials.
