How do biosolids benefit the environment?

Use of biosolids can benefit the environment, particularly in areas of degraded soils. The use of biosolids also completes the nutrient cycle by returning nutrients to the land from which they were sourced. Organic matter has been used by humans for thousands of years to improve soil fertility and productivity.

When properly applied and managed, biosolids can:

  • Provide essential plant nutrients;
  • Improve soil structure and moisture retention;
  • Add organic matter; and
  • Reduce soil erosion.

Research and years of experience in the use of biosolids have demonstrated that properly managed land application of biosolids is beneficial to the environment.
