How can biosolids reduce landfill waste?

The choice that states biosolids can reduce landfill waste by recycling nutrients back into the soil is correct because it highlights the beneficial use of biosolids in agriculture and land reclamation. When biosolids are processed, they contain valuable nutrients such as nitrogen, phosphorus, and organic matter. Instead of being sent to a landfill where organic materials can contribute to methane emissions and other environmental issues, these nutrients can be returned to the soil, enhancing soil fertility and promoting plant growth.

This practice not only reduces the volume of waste that requires landfilling but also supports sustainable agricultural practices by enriching soils, thus creating a closed-loop system for nutrient use. By reclaiming and recycling these nutrients, it promotes recycling rather than disposal, which is a key factor in waste management strategies aimed at reducing the environmental footprint of waste.
