Festival goers’ urine helps create ‘pisner’ beer

Danish brewery Norrebro Bryghus use 54,000 litres of urine collected at the Roskilde music festival to fertilise barley for their ‘pisner’ beer

Danish brewery Norrebro Bryghus have produced a beer with the help of 54,000 litres of urine collected at the 2015 Roskilde music festival.

The new product is called Pisner – but contains no human waste. Instead, the urine was used to fertilise the barley for the beer, rather than use more traditional methods – and it's called Beercycling.

CEO at the Danish Agriculture and Food Council Karen Hækkerup tells Visit Copenhagen: “Just as we have seen shops sell goods that would otherwise have been thrown out, Beercycling allows us to recycle a product that is normally flushed down the drain.

“When it comes to circular economy, Danish farmers are some of the best in the world. If you can brew a beer with urine as fertiliser, you can recycle almost anything.”

Norrebro Bryghus chief executive Henrik Vang adds: “We want to be a part of the Beercycling project partly due to the story it has already told, but also because it is interesting to partake in a project, which addresses the challenges of sustainability and circular economy. Basically, it is a cool project.”

The urine collected resulted in enough barley to produce 60,000 bottles of beer and the pisner will be available to buy next month.
