Wee from festival portaloos is being collected by boffins to help make beer.
Around 20,000 litres of pee is expected to be transported back to researchers.
Once the urine has been collected, it will be spread on fields where malted barley is grown.

The wee is treated prior to this and dried into a powder form so that it can be easily placed on the fields.
The harvest will then be used to make beer, according to professor Björn Vinnerås.
On 29 April, ten yellow portaloos were set up by the sanitation company, Sanitation360.
Each one was designed so that it could be used both standing and sitting.
A safety net was placed over each bowl to prevent visitors leaving anything other than pee.

Urine was also collected around the same time last year, however this year’s 20,000 litres is double that of last year, as reported by What’s The Jam.
Björn, a professor at the Swedish University of Agricultural Sciences and Nicola Parfitt, the project manager at Sanitation360, collaborated with Gotland’s breweries on the project.
Both Björn and Nicola aim to develop a sustainable method for converting human wee into high-quality fertilizer.

According to the press release, using human urine as fertilizer has the potential to greatly reduce the use of artificial fertilizers.
Artificial fertilizers contribute to eutrophication of waterways, which describes pollution that occurs when a lake or stream becomes over-rich in plant nutrients.
They also cause greenhouse gas emissions during production.
The collection took place at the Ekonomikum Park in Uppsala, a city near Stockholm, Sweden.
Portaloos were set up during the Walpurgis Day celebrations, an annual traditional European celebration which marks the beginning of spring and the coming of summer.
