Researchers use solar to turn human waste into fertilizer

Stanford University researchers have built a photovoltaic-thermal electrochemical stripping system that extracts fertilizer nutrients from human urine. They say the system could provide a cost-effective alternative in regions with limited access to conventional fertilizers. A research team from Stanford University has developed a prototype that uses solar energy to extract nutrients from human urine to create a sustainable fertilizer. They presented the system in "Prototyping and modelling a photovoltaic-thermal electrochemical stripping system for distributed urine nitrogen recovery," available ...
