Thankfully the beer itself did not contain pee, and one Danish reviewer said it 'didn't take like p*ss, not at all.'Īfter successfully demonstrating the use of urine to grow the grain, the method could take off among other breweries around the world. The brewery collected more than 10,000 gallons of urine from Denmark's Roskilde Music Festival in 2015, which was used to fertilise barley fields. Nørrebro Bryghus, which has won awards at the prestigious World Beer Cup, has a beer called 'Pisner' that uses urine as fertiliser during the brewing process. The experiments recalled the the 2015 blockbuster film The Martian, where Matt Damon plays a stranded astronaut that manages to survive on Mars after using his own faeces to grow potatoes.Ī Copenhagen brewery has been using urine collected at a music festival to help make its beer, in a project branded 'beercycling'. 'Using locally available resources such as human excreta to produce bio-based recycling fertilisers can substitute mineral fertilisers and thereby promote environmentally friendly food production,' they reported. The research could mean we soon have a plentiful and inexhaustible supply of fertiliser to grow cabbages and other vegetables in.Ĭomposting poo rather than flushing it would also bring down water use and negate the need for synthetic fertilisers, which can harm the environment with higher nitrogen and phosphorus levels. They also had success with nitrified urine fertilisers' (NUFs) - modern products synthetised from human urine collected separately from faeces. The experts used faecal compost recycled from dry toilets to grow the successful yields, although they said 'consequences of long-term application of fecal compost requires further investigation'.
Last week, scientists at University of Hohenheim reported that white cabbages grown in human faeces are safe to eat.
