We recover
value from your
sludge

Yes, literally. NPHarvest captures nutrients from nutrient-rich wastewater with 90% recovery efficiency — and help municipalities, farmers, and biogas plant operators do more with what’s already flowing

Wastewater isn’t the problem. Wasting it is.

At NPHarvest, we rethink how wastewater is handled — turning what used to be a headache into a resource. It’s circular economy thinking, backed by serious science.

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.

From factories to farms, and everywhere in between.

Tech that turns wastewater into a resource.

Our proprietary process is based on hydrophobic membrane stripping to recover nitrogen and precipitation with calcium to recover phosphorus. It’s easy and cost-efficient to operate, provides a high-quality end-product, and handles suspended solids up to 3 %.

Low operational costs

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.

High-quality end-product

We recover nitrogen as a pure ammonia salt and phosphorus as amorphous calcium phosphate. Both are not only useful but necessary for fertilizer production.

Easy and reliable

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.

Invest in the future of wastewater. Literally.

Our startup is building scalable, research-based tech that turns sewage into circular economy wins. If you’re looking for returns with impact, this is where the sh*it gets serious.
