Espoo-based NPHarvest has been selected for Business Finland’s Deep Tech Accelerator, unlocking a €1.2 million phased funding pathway to accelerate the commercialization of its nutrient recovery technology, which converts liquid waste streams into usable fertilizer inputs. The milestone-based funding builds on €2.2 million in prior backing from investors including Nordic Foodtech VC and the Finnish Ministry of the Environment, and follows a year of technical progress that saw the company deploy its first industrial-scale demonstrator and validate performance against conventional fertilizers. NPHarvest will use the new capital to scale its technology, move from demonstrators to repeatable deployments, and prepare for international expansion, targeting Europe’s growing waste-to-energy sector where tightening nutrient regulations are driving demand for efficient, export-ready recovery solutions.
NPHarvest is addressing a growing bottleneck in Europe’s waste-to-energy and agricultural systems. As organic waste-to-energy capacity expands, increasing volumes of nutrient-rich liquid digestate are being generated. In regions such as Northern Germany, Northern France, and the Benelux, stricter EU limits on nitrogen application have made it increasingly difficult to spread these nutrients locally. As a result, plant operators are forced to transport excess liquid waste over long distances, driving up costs and emissions.
The company’s technology is designed to recover nutrients directly from these liquid waste streams and transform them into fertilizer products that can be transported and applied where regulations allow and demand exists. By doing so, NPHarvest aims to turn a regulatory and logistical challenge into a scalable, circular-economy solution for both waste operators and agriculture.
“In Europe, the limiting factor in fertilizer production is no longer nutrient availability, but how and where those nutrients can be recovered and reused,” said Juho Uzkurt Kaljunen, CEO of NPHarvest. “Large volumes already exist in liquid waste streams generated by waste-to-energy plants, yet current systems struggle to convert them into inputs that can be used where they’re permitted and needed. This funding allows us to translate that constraint into repeatable, scalable deployments.”
Throughout 2025, NPHarvest reached several technical milestones based on earlier research conducted at Aalto University. The company launched its first industrial-scale demonstrator nutrient recovery unit at a waste-to-energy plant in Ankara, Türkiye, marking a step beyond pilot projects toward real-world industrial deployment. In parallel, field trials conducted with University of Helsinki’s Viikki research farm showed that NPHarvest’s recycled nitrogen and phosphorus perform on par with conventional synthetic fertilizers.
With the Deep Tech Accelerator funding in place, NPHarvest plans to further advance its core technology while laying the groundwork for full-scale commercialization. The company will focus on turning validated performance into standardized, repeatable systems that can be deployed across multiple sites, with an eye on Europe’s largest waste-to-energy and fertilizer markets.
As pressure mounts to reduce fertilizer dependency, improve nutrient circularity, and comply with tightening environmental regulations, NPHarvest’s approach positions it at the intersection of cleantech, agriculture, and industrial sustainability—an area where scalable solutions are increasingly in demand.
