# Festival Urine Recycling Programs Roskilde Festival Introduced From Piss to Pilsner By Kanesa David | Written with AI assistance | Published 2026-03-30 | Unique Source: Trend Hunter, https://www.trendhunter.com/trends/from-piss-to-pilsner References: [newatlas](https://newatlas.com/roskilde-festival-beercycling-project/38342/) & [roskilde-festival.dk](https://www.roskilde-festival.dk/en)  Roskilde Festival and the Danish Agriculture & Food Council introduced a beercycling initiative called From Piss to Pilsner that collected attendee urine, featuring dedicated urinals, storage tanks and P-Mate urine directors for female contributors. The scheme routed festival liquid waste to nearby farms so the nutrient-rich fluid could fertilize malting barley destined for beer production. Organizers fitted strategically placed collection stations across the week-long event and coordinated transfers of stored urine to agricultural partners for field application. The program aimed to close a local-loop resource cycle by converting a plentiful waste stream into a crop input, with the harvested barley then used to brew beer for a future festival. For consumers, the effort reframed festival waste as a tangible sustainability action that links attendee behavior to product outcomes, offering a memorable, low-tech example of circular resource use at large events.
