We are so happy that on the IVA list, our group is one among the 100 projects with our urine-based fertiliser! Read more here!

The barley fertilized with our dried urine is growing well. The picture meant to be posted here as well (but can’t) is taken 27 days after planting and it looks really good!

At the end of April all new professors at SLU were having their installation lectures. A totally new concept with online lectures and the audience could ask questions online. Björn gave his lecture with focus on how we in the future can decrease the emissions to the environment by disconnecting us from the water and… Continue reading Professor installation lecture

On 5th of March, Prithvi had his pre-dissertation seminar: Alklaine Urine Dehydration – how to dry urine and recover nutrients. David Gustavsson from VA SYD/Sweden Water Research was Prithvi’s opponent at the seminar and he quizzed Prithvi on his published papers as well as his preliminary thesis (or kappa). Overall, it was very interesting and… Continue reading Prithvi Simha’s pre-dissertation PhD seminar

We recently published a new paper on the use of Magnesium Oxide as an alkaline substrate for dehydrating urine in the journal Frontiers in Environmental Science. https://www.frontiersin.org/articles/10.3389/fenvs.2020.619901/full Abstract: Fresh human urine, after it is alkalized to prevent the enzymatic hydrolysis of urea, can be dehydrated to reduce its volume and to produce a solid fertilizer.… Continue reading Using MgO for Alkaline Dehydration of Human Urine Collected in Source-Separated Sanitation Systems
