Björn Vinnerås, Jenna Senecal and Jennifer McConville attended the startup-meeting in Hannover during the second week of January. Included in the project from SLU is also Prithvi Simha and two PhD students under employment. Our main work is within the “Swedish pilot region”, where we will focus on the upscaling of the urine dehydration process. Our focus is the first two work packages WP1 – Blue printing the regional clusters and WP2 – Monitoring and assessing the benefits. Jenna was presenting the Swedish pilot region with the full cycle of urine collection to food production. See more at the project home page https://p2green.eu/

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
