This week, the Environmental Engineering group at SLU starts its full-scale urine drying experiments. The group has designed and built 6 household-scale urine drying prototypes for the experiments. Over the coming months, every day, these units will be drying 24 litres of urine. The biggest challenge so far has been to collect enough daily fresh urine to feed the prototypes. We thank all those who have donated urine so far, and hope that these donating keep coming. Your donations can potentially help revolutionise sanitation!

Prithvi Simha, Jenna Senecal, and Björn Vinnerås just returned after spending a week in Durban, South Africa. We travelled there to present our novel sanitation technology called alkaline urine dehydration to several potential collaborators, and to see if the technology could fit into the local context. We met with sanitation experts from the Pollution Research Group at the University of KwaZulu-Natal, the eThekwini Municipality, and Envirosan (a toilet manufacturer based in Durban). The trip was extremely fruitful with a positive response from all experts about our technology. We even brought back with us two new urine-diverting toilets to test our system with (thank you Envirosan!). Our next step will be to return to Durban with a pilot-scale urine drying system that the Pollution Research Group will test at their research facility. Following this, drying units will also be tested in people’s homes at the eThekwini municipality. A big thank you to Chris Buckley for co-ordinating the trip & to the NJ Committee on Global Affairs for the financial assistance.SLU EnviroSan Loot; PC: Chris Buckley

How much water do each of us use every day? Can future sanitation systems and off-the-grid houses be designed so as to minimize energy and water consumption? Where does wastewater management fit into the waste hierarchy/pyramid? In his presentation, Björn Vinnerås, Associate Professor at SLU shares with us his vision of future housing: a future where there is ‘no need for network connections, neither electricity nor water, and nor wastewater’.
