If you need more of an excuse to attend the Roskilde Music Festival in Denmark, you can put your pee to good use.

The festival’s organizers partnered with the Danish Agriculture & Food Council for their “From Piss to Pilsner” initiative or “beercycling.” When I think of “beercycling,” I think of those dopey bicycle contraptions where 10 people pedal to various bars.

Basically, urine was collected from the 100,000 festival goers and then shipped to farms to be used as fertilizer for barley. By 2017, the barley grown will be used in the brewing process in time to be served at that year’s festival. Everybody wins?

Lief Nielsen of DAFC told The Guardian:  “The huge amount of urine produced at festivals was having a negative impact on the environment and the sewage system, but beercycling will turn the urine into a resource. 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.”

The joke here is that some mass market beer already tastes like piss anyway.
