We are extremely happy to share our latest milestone – something that we set as a aim almost ten years ago – to produce a dry urine fertiliser with the same nutrient content as that of synthetic fertilisers so that we can replace their use in agricultural systems. Earlier this year, we managed to produce the first 20 kg batch of our solid urine based fertiliser, Granurin, with >15% nitrogen content. The urine was collected last year from public urinals on Gotland as part of the N2Brew project, and treated by Sanitation360 AB, with final processing and fertiliser pelletisation done at SLU – Swedish University of Agricultural Sciences by Bjorn, Jenna and Prithvi.
