In a recent study published in Water Research, members of the Kretsloppsteknik group investigated the possibility of alkalising human urine by anion-exchange and dehydrating urine into a dry fertiliser powder.Fresh urine was passed through an ion-exchanger, stabilised by alkalisation (pH >10), added to an alkaline media (wood ash/alkalised biochar) and dehydrated
