Our Story
The most sustainable agriculture products on the planet!
Our process
We help identify and collect undervalued resources and/or waste. The PAE Living Building, in Portland, Oregon, is the first building in the world to manufacture (or create) carbon neutral fertilizer products from waste.
A team of engineers developed an ultra pure distillation process able to capture nutrients from waste water. Ammonia vapor is condensed as, ammonium bicarbonate. This clear solution is a ready-to-use agricultural amendment with a high pH and containing approximately 6% ammonium-N.
What is left is treated again by adding magnesium which precipitates out Phosphorous creating a slurry. Once the slurry is collected and dried it is very affective slow-release phosphorus rich fertilizer.
The remaining sterile waste containing salt, trace constituents, and other organic compounds are safely disposed.
Who We Are
Nutrient Recovery Services (NRS) is a collection of engineers, scientists, and designers creating ecologically sound agricultural additives and fertilizers. Our contribution to a circular nutrient economy is a critical component to repairing the way we produce food and fiber in our communities. Together with our partner organizations we are working to create the change we want to see.
