Circular Economy in the Biosolids Management by Nexus Approach: A View to Enhancing Safe Nutrient Recycling—Pathogens, Metals, and Emerging Organic Pollutants Concern
Biosolids are a byproduct of sewage treatment that can create synergies and opportunity costs for promoting a circular economy and the nexus approach (water, energy, and food). They enable a cleaner agricultural production, with food safety in local development. The biosolids contain nutrients that can be recycled by agricultural soils.
