In a major step toward accelerating the circular economy in water management, Byosis, part of Nijhuis Saur Industries (NSI), and AquaMinerals have signed a strategic partnership agreement to support water authorities in the recovery and valorisation of nitrogen from wastewater.
Turning waste into value
Harnessing cutting-edge Byoflex® stripping technology developed by Byosis, nitrogen compounds such as ammonium sulphate and ammonia water can now be efficiently recovered and transformed into sustainable fertilisers. These high-quality, circular products not only reduce environmental impact but also present a valuable economic opportunity for the water sector.
Unlocking the full potential of the circular economy
This collaboration is designed to help water authorities and utilities close the loop on water and resource recovery. With evolving regulations making it easier to reintroduce recovered nitrogen into the market — particularly in agriculture — the need for a coordinated, reliable offtake model is of essence to create scale and have real impact.
By combining AquaMinerals’ unique expertise in material valorisation with Byosis technological and operational excellence, this partnership ensures a stable, scalable, and bundled supply of nitrogen products that unlock economies of scale and reduces risks for stakeholders.
Building a resilient resource recovery chain
“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,” says 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, emphasises the long-term vision: “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.”
Lowering barriers with a ‘Customer-for-Life’ mindset
Wilbert Menkveld, CTO of NSI, highlights the broader significance: “Water authorities and utilities are eager to reduce their carbon footprint and become more resilient. While nitrogen recovery is technically and economically viable, this partnership will provide the required off-take of the recovered ammonia and removing one of the last barriers to set a new global standard for recovering nitrogen.”
