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.
We give tours monthly of the system. Please contact us if you are interested in joining or would like to book a private group tour. We love visitors!
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.
