SLU has developed an innovative technology that converts human urine to high-quality solid fertiliser. On Gotland, SLU and Gotlands Bryggeri have also shown that urine can effectively fertilise barley, which can be processed further to make beer. Over the next few years, SLU and the Bryggeri need to produce 150 m3 of such beer. But the Bryggeri is concerned about micropollutants that can be present in urine (e.g., pharmaceuticals). Through a three-year project, we aim to address this concern. First, we will do a baseline study to evaluate fate of micropollutants in the urine chain (fertiliser, barley & beer). Second, techniques (advanced oxidation & extraction) will be developed to remove micropollutants so that only plant-essential nutrients are recycled back to farmland. Third, using social science methods and system dynamics modelling, support for recycling urine among food consumers will be assessed. Finally, all the evidence will be presented to stakeholders in the food industry.
SLU har utvecklat en innovativ teknik för att konvertera humanurin till ett fast gödselmedel av hög kvalitet. SLU har i ett projekt på Gotland, tillsammans med Gotlands Bryggeri, visat att den producerade gödsel fungerar väl som gödsel till maltkorn, som sedan används i ölproduktion. Under de kommande fem åren skall SLU oh Gotlands Bryggeri producera 150 m3 uringödslad öl. Byggeriet har vissa betänkligheter kring mikroföroreningar som finns i urinen, t.ex. läkemedel. Vi vill utvärdera möjligheten att hantera dessa substanser i ett treårigt projekt. Först kommer vi att göra en screening där vi utvärderar vad som händer med mikroföroreningarna i urinhanteringskedjan (gödsel, korn, öl). Sedan kommer behandlingstekniker (avancerad oxidering och extraktion) utvecklas för att avlägsna mikroföroreningar så att endast växtnäring återförs till fälten. Den tredje delen är att använda samhällsvetenskapliga metoder och systemmodellering för att utvärdera konsumenternas syn på systemet.

Cereal production is limited by many different factors. Leaf diseases are often well known, while diseases on roots are more difficult to identify. Root diseases are often caused by oomycetes, fungus-like microorganisms that live for years in soil and on old root debris, parasitizing the roots of …
