Turning Urban Wastewater into Bio-Based Fertilizers for Sustainable Farming

environmentPilotedTRL 7

Imagine if the waste from city sewers could be recycled into high-quality plant food for farmers. Instead of letting nitrogen and phosphorus pollute our rivers and oceans, this system captures them and sends them back to the soil. It basically creates a loop where city waste feeds the crops that feed the city.

The business problem

What needed solving

Farmers rely on expensive mineral fertilizers while cities struggle with nutrient pollution in wastewater. There is a missing link to move nutrients from urban waste back to rural fields efficiently.

The solution

What was built

A transition data platform, three physical nutrient recovery prototypes in pilot regions, and a business blueprint for scaling circular value chains.

Who can put this to work

Agriculture
any
Target: Commercial Crop Producers

If you are a commercial crop producer dealing with high mineral fertilizer costs — this project developed bio-based fertilizers from urban waste that provide a viable alternative to chemical inputs. This reduces reliance on expensive imports and lowers soil pollution.

Waste Management
enterprise
Target: Municipal Wastewater Treatment Plant Operators

If you are a plant operator dealing with nutrient runoff penalties — this project developed nutrient capture systems that convert waste streams into sellable products. This turns a waste disposal problem into a new revenue stream from bio-fertilizers.

Biotechnology
SME
Target: Bio-fertilizer Manufacturers

If you are a manufacturer dealing with raw material scarcity — this project developed a blueprint for scaling circular nutrient flows. You can use these models to set up production in 14 different European countries.

Frequently asked

Quick answers

What is the cost or price of the bio-fertilizers?

Based on available project data, specific pricing or cost per ton is not mentioned; however, the project focuses on creating circular business models to ensure long-term economic viability.

Can this be scaled to an industrial level?

Yes, the project is testing three prototypes in pilot regions and creating blueprints specifically designed to help users initiate, manage, and scale these solutions in follower regions.

Who owns the IP or how is licensing handled?

Based on available project data, the project provides a blueprint for circular business models, but specific licensing terms for the technology are not detailed.

How does this handle EU environmental regulations?

The project produces policy recommendations for the EU Commission to help establish a uniform legislative framework that supports innovative bioeconomy products.

When will the solutions be available for commercial use?

The project period runs until 2026-11-30, with prototypes already being installed in three pilot regions.

Consortium

Who built it

The consortium is heavily weighted toward commercial application, with 18 industry partners (53% ratio) and 11 SMEs. This suggests a strong focus on market entry rather than just academic research, supported by a broad geographic reach across 14 countries to ensure the business models work in different regulatory environments.
