Abstract
Phosphorus (P), known as “life's bottleneck,” is an essential element of human nutrition, which cannot be replaced by any other element. Demand for phosphorus is expected to increase because of the world's growing population and its need for food; however, the global reserves of high-grade phosphate rock are dwindling. Phosphorus comes from primary (from phosphate rock deposits) and secondary (from waste streams) resources. Because the major part of the phosphate obtained from wastewater is transferred to sludge (about 90%), the most promising phosphorus-rich residues are sewage sludge (SS) and sewage sludge ash (SSA). The objective of this chapter is to discuss the importance of phosphorus for human nutrition, possible sources of phosphorus in the wastewater sector, phosphorus extraction from sewage sludge (SS), and phosphorus extraction from SSA. This approach to SS and SSA management is consistent with the circular economy (CE) concept established by the Europe 2020 Strategy for smart, sustainable, and inclusive growth.
