 Phosphorus is an essential element for all living organisms, but can become a pollutant when released into the environment. As the global population increases, so does the demand for this finite resource, leading to a potential shortage of phosphate rock in the near future. To address this issue, researchers are investigating ways to recover phosphorus from wastewater and sludge, with chemical precipitation being one of the most common methods. The goal is to create a phosphorus-rich mineral that can be used as a fertilizer, such as Stravite. This review paper examines the current state of phosphorus production and consumption, and explores how these technologies could be integrated into existing wastewater treatment systems to achieve a more sustainable water-energy nutrient nexus.
