Sanitation systems that are designed for safe and effective recovery of resources can play an important role in a community's overall resource management. Recovering the resources embedded in excreta and wastewater (like nutrients, water and energy) contributes to achieving Sustainable Development Goal 6 and other sustainable development goals. [5]
The solid residue of sewage sludge treatment, which is a secondary phase in the wastewater treatment process, is also called humus.
