Urine to Water & Beer
Scientists at the University of Ghent in Belgium have built a novel water-from-urine machine. The urine is collected in a big tank, heated in a solar-powered boiler before passing through the membrane where the water is recovered and nutrients such as potassium, nitrogen and phosphorus are separated. The team recently deployed the machine at a 10-day music and theatre festival in central Ghent, recovering 1,000 litres of water from the urine of revelers. The aim is to install larger versions of the machine in sports venues or airports but also to take it to a rural community in the developing world where fertilizers and reliable drinking water are short in supply. From sewer to brewer, the research team also experiments the water recovered from the city festival to make one of Belgium's most coveted specialties, beer.
