Danish Music Festival Roskilde Will Recycle Festival-Goers’ Urine For Beer!
‘It is totally possible to use human urine as a fertilizer instead of industrial fertilizer,’ declared researcher Heinonen-Tanski. Why not? Urine contains urea, a good source of nitrogen, plus potassium and phosphorus, all needed by plants and found in fertilizers. Plus it is always available, a typical human urinates about 500 liters per year, and about 200 of them must be produced during music festivals!
