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
Degradation of poly-L-lactic acid biopolymer films in Ca(OH)2-dosed fresh human urine
We have recently published a paper in Resources, Conservation and Recycling which looks into the possibility of using Poly-L-Lactic Acid (PLLA) biopolymer to capsulate and safely dose chemicals to human urine. Alkaline dehydration of urine for recycling of plant essential nutrients requires fresh urine to be stabilized with alkali or metal hydroxides. Improper handling and… Continue reading Degradation of poly-L-lactic acid biopolymer films in Ca(OH)2-dosed fresh human urine
Urine recycling featured in flagship report of the UNEP and Global Wastewater Initiative
The flagship report of the UN Environment Programme (#UNEP) and Global Wastewater Initiative (#GWWI) was recently released at the #WorldWaterWeek in Stockholm a few days ago! Prithvi Simha from the group contributed to the report as one of the authors. This new report, “Wastewater – Turning problem to solution” urges decision makers and action takers from all… Continue reading Urine recycling featured in flagship report of the UNEP and Global Wastewater Initiative
Scaling up urine concentration technologies – what are the impacts?
There is a growing trend for nutrient recovery from wastewater as part of the transition to a circular economy. Most nutrients in household wastewater originate from urine and one way to facilitate reuse of these nutrients is to concentrate the urine into fertilizer products. Urine concentration technologies are still in the development phase and not… Continue reading Scaling up urine concentration technologies – what are the impacts?
Can urine help save food production under crises?
Prithvi spoke with Agnes Bondesson, SLU Global’s International Scientific Communications Officer about the ongoing food and fertiliser price inflation. Check out the article here: https://internt.slu.se/en/news-originals/2022/3/can-urine-help-save-food-production-under-crises/ or read below – With the current state in the world, seen to conflicts and climate change, the question about food production in case of short-term or long-term crises has… Continue reading Can urine help save food production under crises?
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
