Under a cloudless sky, shirtless Vikings with plastic cups of beer in hand are queuing excitedly along a patch of sawdust-covered earth to urinate in a metal trough. Their “contributions” are being collected in specially designed storage tanks, which will then be transported to nearby fields to fertilise malting barley for brewing beer.
“From piss to pilsner” is a new initiative being launched at Roskilde – northern Europe’s largest music festival – in Zealand, Denmark, this week. Organisers hope to collect 25,000 litres of urine from more than 100,000 festivalgoers.
If everything goes to plan, guests at Roskilde 2017 will be served beer from barley fertilised by their own urine. “It’s about changing our approach to waste, from being a burden to being a valuable resource,” says Leif Nielsen from the Danish Agriculture & Food Council (DAFC), which is partnering with festival organisers to promote “beercycling”.
“The huge amount of urine produced at festivals was having a negative impact on the environment and the sewage system,” says Nielsen. “But beercycling will turn the urine into a resource.” He’s confident that the project will be a success. “I think most people can see the reason and the fun behind making a personal contribution to beer brewing, and the fact that rock music is involved will help us get our message across.”
