 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. To address this issue, researchers are developing methods to recover phosphorus from wastewater and sludge, with chemical precipitation being the most common technique. The goal is to create a sustainable system that integrates wastewater treatment with phosphorus recovery, thus reducing the environmental impacts associated with phosphorus use.
