We Recycle Your Pee

Want to reduce your waste? With our uniquely developed urine stabilizer and unisex urinal or urine cassette, you can do just that! You simply pour the powder into the collection tank of the urine diverting toilet or urinal, and it will treat and concentrate the urine for you.

Either you can use the stabilized urine directly in your garden, or we can collect and further treat it into a granular, nutrient rich fertilizer for farmers. The outcome of this solution is cleaner water, safer toilets and sustainable communities.

We successfully preserve the majority of nitrogen in urine during processing, concentrating it to the ideal target level of 15%, and producing a solid based urine fertilizer. Farmers can easily store, transport and more importantly, use our fertilizer with their existing conventional farming equipment.

What about pharmaceuticals About us

Urine treatment

Thanks to our innovative acid-based stabiliser, urine is treated directly in the collection tank of each urinal or urine-diverting toilet. This process lowers the pH, preserving over 90 % of the nitrogen and 100 % of the phosphorus and potassium while preventing ammonia formation—and with it, reducing unpleasant odors. In the next stage, convective air-drying removes about 95 % of the liquid volume, eliminating the need for bulky piping or large storage tanks.

Collection and Transport

We collect urine from urinals and urine-diverting toilets across Sweden and transport it to our facilities, where it’s dried into a nutrient-rich fertilizer. Customers can also choose to keep it as a stabilized liquid and apply it directly to their own crops or gardens. In the future, curbside collection may include not only bottles, cans, and food scraps, but also a container of concentrated, circular fertilizer ready for reuse.

Returning the nutrient

The urine-based fertilizer contains the same type and concentration of plant nutrients found in commercial fertilizers. We produce a fertilizer that can be used with the same equipment as conventional pelletized fertilizer to make urine fertilizer use more accessible. Large-scale implementation of urine treatment technology could replace 19% of the nitrogen and 21% of the phosphorus used each year in commercial fertilisers across Sweden.

Advantages for Wastewater Treatment Plants

Our solution complements existing wastewater treatment system, by helping increase the capacity a treatment plant by up to 60% due to the decrease in nutrient load. By converting urine into a dried fertiliser, the flows of polluting plant nutrients to the environment can be minimised, which in turn helps to limit nutrient overload and dead zones in aquatic ecosystem. This lowers the impact of human waste on climate change.
