On 25th March, three members from our group, Prithvi Simha, Giulio Zorzetto, and Caroline Karlsson headed off to Finland with a trailer full of parts that make up a urine drying treatment system. They arrived after in Finland after an overnight ferry crossing and are currently in the city of Tampere. Here, with the help… Continue reading Sweden to Finland – the urine drying technology travels for pilot testing!

Since the beginning of this year, the Kretsloppsteknik group has been working towards building a system to pilot the urine drying technology. Several members of the group have been involved in designing, constructing, simulating and testing a system with a capacity to treat 30 L of urine every day in <1 square meters surface area.… Continue reading Constructing a pilot urine drying system

On Wednesday (13/2-2019) the Director General of SIDA Carin Jämtin and the Vice-Chancellor of SLU Karin Holmgren honoured us with a visit to our BSF facility. Also on the visit, from SIDA, were Senior Research Advisor Eva Ohlsson and Policy Advisor Esse Nilsson, and from SLU Pro Vice-Chancellor, international relations Ylva Hillbur, Head of SLU… Continue reading Director General of SIDA and the Vice-Chancellor of SLU visited the Greenhouse

After almost half a year of work, Nils Ewald presented his master’s thesis last week for the audience at the Department of Molecular Sciences. In the thesis he investigated the relation between the fatty acid composition of the Black soldier fly larvae, and the different waste materials that were fed to the larvae. From the… Continue reading Nils Ewald, M.Sc. thesis on fatty acid composition of BSF larvae

Sahar Dalahmeh, Researcher at Kretsloppsteknik is currently visiting the Center for Global Safe WASH at Emory to develop co-operation between SLU, Emory University, and the Royal Scientific Society of Jordan in research and education about microbiological and pharmaceutical risks associated with the use of wastewater in agriculture. As part of the CGSW Seminar Series, Sahar presented… Continue reading Center for Global Safe WASH Seminar at Emory

In this study, published in the journal Water, we assessed how several design/operating parameters affect the efficiency of biochar filtration in removing organic matter (COD) and nutrients (Tot-N, NH4-N, Tot-P, PO4-P) from wastewater. We compared the process efficiency of different biochar parent materials, biochar diameters, hydraulic and organic loading rates (HLR and OLR) and one… Continue reading Which design and operating conditions affect pollutant removal from wastewater in biochar filters?

The group is happy to share that we have received a 4 million SEK research project grant within the area of development research from the Swedish Research Council. The project, “UDT 2.0 – Urine Dehydration Technology for Sanitation 2.0“, has the broader objective of moving sanitation research beyond the toilet (Urine-Diverting Toilet; UDT) by demonstrating a… Continue reading New Grant for developing urine drying technology in Bolivia

Following a successfull application to the SLU Climate Fund, we plan to replace a conventional toilet at SLU’s MVM building with a urine-diverting flush toilet during the spring. Urine-diverting toilets handle urine and faeces separately – the toilet leads the urine to a separate collection system while faeces are flushed with water, just like a… Continue reading SLU to have its own urine-diverting toilet!
