Nijhuis Saur Industries and AquaMinerals partner on nitrogen recovery

Byosis, part of Nijhuis Saur Industries (NSI), and AquaMinerals have signed a strategic partnership agreement to support water authorities in the recovery and valorization of nitrogen from wastewater.

Harnessing cutting-edge Byoflex stripping technology developed by Byosis, nitrogen compounds such as ammonium sulfate and ammonia water can now be efficiently recovered and transformed into sustainable fertilizers. These high-quality, circular products not only reduce environmental impact but also present a valuable economic opportunity for the water sector.

This collaboration is designed to help water authorities and utilities close the loop on water and resource recovery. By combining AquaMinerals’ unique expertise in material valorization with Byosis technological and operational excellence, the partnership will ensure a stable, scalable, and bundled supply of nitrogen products.

“This partnership enables us to offer complete certainty regarding the off take of recovered nitrogen, removing a major hurdle for our clients while preserving operational flexibility,” said Jan van den Broek, CEO of Byosis. “By smartly connecting supply with demand, we create tangible value across the chain fueling lasting and stable relationships.”

Olaf van der Kolk, CEO of AquaMinerals, said: “Building new material chains requires future-proof collaboration. This partnership with Nijhuis Saur Industries brings together deep technical expertise and strategic market access — a powerful combination that benefits both water authorities and end-users of these nitrogen products.”
