Researchers at the University of Surrey are tackling the global phosphorus shortage by extracting the mineral from human urine. With mined phosphorus predicted to run out in the next 50 to 100 years, this innovative project aims to use phosphorus found in urine – a plentiful resource. Led by Maano Tshimange, the team is developing a filtration method to separate phosphorus from water in urine, making it practical to collect and use.
The pilot project involves collecting 15 litres of urine from students at the university over a year. If successful, this method could supply up to 11% of the world’s phosphorus needs. This project highlights the potential of using waste products as valuable resources for sustainable solutions.
