We are making history! Our dried urine was applied with a seeder while planting barley. This could be the first time that urine fertilizer was applied in such a way. The fact that we are able to produce a urine based fertilizer that is usable with conventional farming equipment is very exciting. We have three treatments: no fertilizer, conventional fertilizer and urine fertilizer. The urine fertilizer has 7.2 % nitrogen and we applied 100 kg N per ha.
På VA SYDs huvudkontor installeras nu ett innovativt toalettsystem som torkar urinen till en torr växtnäring, direkt under toaletten. Genom att sortera ut urinen kan det mesta av näringen återvinnas ur avloppet. Forskare på Sveriges Lantbruksuniversitet (SLU) har arbetat fram den nya tekniken, som ska testas i Malmö och Lund, inom projektet REWAISE.
At VA SYD’s head office, our innovative toilet system is now being installed to dry the urine to solid fertilizer, directly under the toilet. By sorting out the urine, most of the nutrients can be recycled from the sewage. We, researchers, at the Swedish University of Agricultural Sciences (SLU) have been developing the new technology, which will be tested in Malmö and Lund, within the REWAISE project.
