A machine that transforms urine into drinking water and fertilizer has been invented by Belgian scientists. The urine is heated with solar power and then passed through a membrane which recovers the water and separates out nutrients including phosphorus, potassium and nitrogen. The machine was trialled at a festival in Belgium, where it recovered 1,000 litres of water. The scientists hope that the system can also be used in developing and off-grid regions.
