NPHarvest
NPHarvest captures nutrients from nutrient-rich wastewater with up to 90% recovery efficiency — and help municipalities, farmers, and biogas plant operators do more with what’s already flowing.
Description
About NPHarvest
We’re a team of researchers, engineers, and environmental problem-solvers with deep roots in science and a drive to make it real. We’ve seen how broken the nutrient cycle is—and we’re here to fix it.
What began with years of academic research has grown into something far more ambitious. We’ve tested our solution in the lab and the field and are now scaling it up for real-world impact.
With decades of experience in environmental engineering and wastewater treatment, we’re united by one belief: technology can turn the circular economy from a buzzword to the optimal way forward. And we’re building the tech to make it happen.
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.
Curious how it works in your world? Here is how our solution works by industry.
Wastewater Treatment
Lower OpEx, reduce emissions, and meet regulations with ease—without changing your mainline process.
Wastewater treatment facilities are under pressure to meet strict nutrient discharge limits while managing rising costs and emissions. Traditional nitrogen removal is energy-hungry and emits potent greenhouse gases like N₂O. NPHarvest offers a smarter way.
Our technology works on concentrated side streams—like digester reject water—before they hit the mainline. We recover up to 90% of nitrogen and phosphorus from these streams in pure, usable form. The result? Lower load on your mainline, reduced net energy and chemical consumption, and smaller emissions footprint.

Biogas Plants
Stop losing money on reject water. Start recovering value from every cubic meter.
Biogas production leaves you with energy—and a wastewater challenge. The nutrient-rich reject water from digestate is costly to spread, store, move, or treat. NPHarvest changes the equation by letting you recover valuable nutrients on-site, cutting costs while unlocking a potential new revenue stream.
Our system recovers up to 90% of nitrogen and phosphorus from liquid digestate without the need for energy-intensive heating, pressurization, or extensive chemicals. It’s designed to tolerate total suspended solids up to 3 % content and integrates easily into existing flows.

Animal Farms
Reduce nitrogen levels, stay compliant, and unlock new value—without changing how you farm.
For animal farmers, tighter spreading regulations and rising fertilizer prices are adding stress to an already challenging business. NPHarvest offers a low-maintenance, plug-in solution that captures nitrogen and phosphorus from liquid manure, helping you stay compliant and generate new value from what used to be a problem.
Our patented process doesn’t treat solids or require complex infrastructure changes. Instead, it targets nutrient-rich liquid waste, extracting pure ammonium salts and phosphorus products that can be resold or reused as fertilizer.

Other Industrial Streams
Stay compliant, lower OpEx and reduce emissions. Focus on your core – let us handle the waste.
Nutrient discharge and spreading limits affect every operator with nutrient-rich wastewater. NPHarvest’s solution captures up to 90% of nitrogen and phosphorus from nutrient-rich liquid waste streams.
Any stream with high nitrogen concentration – we’re on it! From incineration plants to plant-based production facilities, a variety of industries bother with concentrated liquid waste.
Our patented process can be easily integrated and operated in existing facilities. What’s more – it treats your wastewater with low operational costs and extracts pure nutrients that can be resold or handled by our team.

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 physicochemical 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.
