Publication on field testing alkaline urine dehydration at pilot-scale in Finland
In early 2019, we designed and installed a pilot shell system to dry fresh urine collected from about 100 toilet users each day (or a maximum of 30 liters of urine day-1). The system was implemented at a Finnish army training ground (Camp Mauri) belonging to Pori Brigade, which is a garrison in Säkylä, Finland… Continue reading Publication on field testing alkaline urine dehydration at pilot-scale in Finland
New book chapter discusses alkaline urine dehydration at scale
In a bio-based circular economy, domestic wastewater has a significant role to play. By separating wastewater into different fractions at the source, it is possible to create new pathways for recycling resources. In a book chapter published in Current Developments in Biotechnology and Bioengineering, Simha et al. discuss about the most nutrient-rich wastewater fraction, human… Continue reading New book chapter discusses alkaline urine dehydration at scale
Half-time PhD Seminar, Prithvi Simha: Alkaline urine dehydration
On 26th April, PhD Candidate Prithvi Simha presented his half-time seminar, “Urine Dehydration Technology for Decentralised Sanitation Systems” at SLU. In the seminar, Prithvi summarised and discussed two research papers & a draft book chapter on urine dehydration. Åke Nordberg, Assoc. Prof. in Bioenergy Technology was the opponent at the 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
Chris Buckley talks to Radio SAfm about urine drying
Last week, following our joint article on urine recycling in The Conversation Africa, Prof. Christopher Buckley from the University of KwZulu-Natal was interviewed by SAfm, South Africa’s national public radio station. In his interview with Stephen Groote, Prof. Buckley talked about our group’s pioneering urine treatment technology, alkaline dehydration, and how the technology holds promise for implementation… Continue reading Chris Buckley talks to Radio SAfm about urine drying
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
Prithvi Simha speaks to SAfm radio station in South Africa about urine drying
This week, following our article on urine recycling in The Conversation UK, Prithvi Simha from the group was invited for a live radio broadcast by SAfm, South Africa’s national public radio station, operated by the South African Broadcasting Corporation. The show is called Late Night Conversation with Patricia Ntuli. During the 30 minute interview, Prithvi and Patricia spoke… Continue reading Prithvi Simha speaks to SAfm radio station in South Africa about urine drying
REWAISE – the new EU H2020 project piloting urine drying in Malmö
The 5-year European H2020 Project REWAISE has just started, involving 24 partners from 11 different European countries, and is led by Aqualia. It aims to shift the paradigm from a linear to a circular, water smart economy. As a part of this project, SLU-Kretsloppsteknik is a linked third partner with the aim to build and install its… Continue reading REWAISE – the new EU H2020 project piloting urine drying in Malmö
We found a way to turn urine into solid fertiliser – it could make farming more sustainable
It’s likely that most of the food you’ll eat today was not farmed sustainably. The global system of food production is the largest human influence on the planet’s natural cycles of nitrogen and phosphorus. How much crops can grow is limited by the amount of these two elements in the soil, so they’re applied as… Continue reading We found a way to turn urine into solid fertiliser – it could make farming more sustainable
