NPHarvest, a Finnish cleantech company developing fertilizer inputs from liquid waste streams, has been selected for up to €1.2 million in funding through Business Finland’s Deep Tech Accelerator program, a competitive initiative designed to help research-driven companies scale internationally based on technical depth and readiness for global commercialization.
The funding, awarded under Business Finland’s Deep Tech Accelerator call, is structured across three phases and tied to technical and commercial milestones. NPHarvest said the program will support the continued development and scale-up of its nutrient recovery technology as it moves from validated performance toward broader deployment.
The company is targeting a growing operational and regulatory challenge emerging across parts of Europe as organic waste-to-energy capacity expands. In regions including Northern Germany, Northern France, and the Benelux, NPHarvest points to nutrient overload as a rising constraint for many plants. Under European Union limits on nitrogen application, excess liquid digestate can no longer be spread locally, driving operators to transport material over longer distances and raising costs.
NPHarvest aims to relieve that bottleneck by recovering nutrients from liquid waste and converting them into usable fertilizer inputs. The company positioned the approach as a pathway for nutrient recovery, shifting from pilot projects to repeatable deployment, and offered systems intended to scale across major waste-to-energy and fertilizer markets.
The Deep Tech Accelerator award builds on €2.2 million in prior funding that NPHarvest said came from industry-leading investors, including Nordic Foodtech VC and the Finnish Ministry of the Environment. The company also highlighted technical progress made throughout 2025, including the launch of its first industrial-scale demonstrator nutrient recovery unit at a waste-to-energy plant in Ankara, Türkiye.
NPHarvest also cited results from field trials conducted with the University of Helsinki’s Viikki research farm, stating that its recycled nitrogen and phosphorus performed on par with conventional synthetic fertilizers. With the accelerator funding in place, the company said it will continue advancing its technology while preparing for full-scale commercialization, with a focus on translating validated performance into repeatable, scalable systems for agricultural and industrial use.
NPHarvest is a spinout from Aalto University and says its patented technology is designed to capture, refine, and recirculate nutrients from wastewater and other liquid waste streams to reduce reliance on imported nutrients. The company said its team has received multiple awards related to its research and pitching, including “Save the Baltic Sea 2025” and European Biomethane Week’s “Inspiration Challenge 2024.”
KEY QUOTE:
“In Europe, the limiting factor in fertilizer production is no longer nutrient availability, but how and where those nutrients can be recovered and reused. 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.”
