Biosolids research focuses on the management and utilization of organic materials that are derived from wastewater treatment processes. Biosolids are nutrient-rich organic materials that are produced as a byproduct of sewage treatment. Researchers in this area study various methods for safely and effectively treating, storing, and applying biosolids to agricultural land, forests, and other ecosystems to improve soil health and fertility. Additionally, biosolids research explores the potential environmental impacts and benefits of using biosolids as a sustainable alternative to chemical fertilizers.
