We recover key nutrients nitrogen and phosphorus, reduce environmental impact, and create new value for industry and agriculture. The result? Smarter systems, lower operational costs, and a more sustainable future — delivered through proven technology.
Our technology requires only increasing pH – no heating, aeration, pressure, or additional chemicals. We’re not only cheaper than other recovery solutions, we also generate savings compared to the current removal processes.
We recover nitrogen as a pure ammonia salt and phosphorus as amorphous calcium phosphate. Both are not only useful but necessary for fertilizer production.
Our process is physiochemical and operated only by dosing an alkaline and an acid. Unlike other parties, we’ve found the way to use hydrophobic membrane stripping with total suspended solids up to 3% in the wastewater.
Field trials found that NPHarvest’s recycled nitrogen and phosphorus nutrients deliver the same performance as commercial ones, producing 30–40% higher yields than unfertilized plots. Helsinki,
Finnish cleantech startup NPHarvest has unveiled an industrial-scale demo unit at the Aslan Biomass biogas plant in Türkiye. It recovers nitrogen and phosphorus from wastewater,
The Finnish startup has developed a nutrient catcher that is installed in wastewater management systems.
