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
Using MgO for Alkaline Dehydration of Human Urine Collected in Source-Separated Sanitation Systems
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

We developed a simple process to recycle urine. Here’s how it’s done in 10 Steps
Every year on November 19, the United Nations celebrates one of public health’s greatest inventions – the toilet. Those who are fortunate enough to have access to one spend more than a year of their lives on it, yet millions of people worldwide cannot use one and many have never even seen one. Invented back… Continue reading We developed a simple process to recycle urine. Here’s how it’s done in 10 Steps
