Just going to the bathroom is contributing to algae blooms and climate change. Sweden alone releases roughly 15400 tonnes of N and 240 tonnes of P into lakes, rivers and seas, through municipal wastewater (including after treatment). Urine contains 80% of the plant nutrients found in wastewater and can be used as a fertilizer instead. At SLU, we have developed a revolutionary technology that converts >90% of the nutrients from urine into a dry fertilizer. The aim of the project is to produce a tailored fertilizer from urine and a new, more sustainably produced, beer that tastes exactly the same as the conventional beer. We will also validate the scalability of nutrient recycling through large-scale beer production. We have partnered with Spiran, a toilet rental company on Gotland, to collect and treat urine > 30 m3 of urine to grow barley as well as with Gotlands Bryggeri (daughter company to Spendrups) to produce a new sustainable beer.
