The scientist has experimented with a variety of methods including solar power. He first turned the urine into water, then after a few more brews he then turned it into beer. The Researchers at the University of Ghent in Belgium have developed a solar-powered machine that converts urine into drinkable water that is then used to brew beer .
It’s all contingent upon solar energy, which means that this technology could be useful in a number of under-resourced areas. To treat the urine, the scientists use the energy of the sun to power membrane distillation, which the team says “holds possible advantages over existing urine treatment technologies.”
As a demonstration of the technology, the researchers recently set up the machine at the Gentse Feesten music festival in central Ghent. Over the course of ten days, they used the hashtag #PeeForScience to collect 1,000 liters of water from the urine of attendees.
In a paper detailing their study, the scientists wrote, “The possibility of potable water production was investigated in human urine by assessing the permeate water quality, maximum recovery and mid-term process stability. It was shown that at least 75 percent of the available water could be recovered from non-hydrolyzed human urine without process failure. As such, membrane distillation is a viable alternative for existing urine treatment.”
