We recover
value from your
sludge

Yes, literally. NPHarvest captures nutrients from wastewater — and help cities, farmers, and 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, less 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

High-quality end-product

We recover nitrogen as a pure ammonia salt and phosphorus as amorphous calcium phosphate

Easy and reliable

Our process is physiochemical and operated only by dosing a base and an acid. It does not clog with TSS up to 3%.

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
