CLIMATE CHANGE IS ONLY THE TIP OF THE ICEBERG
Human modification of the nitrogen cycle is profound.
Nutrients pollution has a devastating effect on the planet.
Urine diversion and recovery of its nutrients, a real solution to the problem.
More than 80% of the nitrogen and 50% of the phosphorus in wastewaters come from urine, even though it represents less than 1% of the volume of water to be treated. Over 70% of micropollutants such as drug residues are contained in urine. Most of the space and energy used to treat wastewater today is therefore dependent on the components of urine. At present, micropollutants are rarely removed and nutrients are hardly recycled.
A solution ready for all
At Eawag (the water research institute of ETH Zürich), we developed over the past 10 years a patented treatment and recovery system where urine is transformed onsite into a valuable and certified fertiliser, Aurin.
Our process recovers nutrients from any building by separating urine and water at the source, using low-flow urinals or separative toilets.
With this technology, you can produce a universal and completely natural fertiliser. In this way, you contribute to a circular economy by recycling nutrients, reducing water consumption, pollution and decreasing the use of artificial fertilisers.
By installing such a system, you will show your innovative and concrete commitment to the environment and sustainability, but in the long run, you can also count on the resale of Aurin to ensure a return on investment.
