Low-Cost Microalgae Production Using Agricultural Wastewater for Bio-Products

environmentPilotedTRL 7

Imagine taking the dirty runoff water from indoor farms and using it as a free buffet for tiny algae. These algae soak up the pollution and carbon from the air, turning waste into a valuable green powder. This powder can then be used to make natural plant food or fish feed, turning a waste problem into a profit center.

The business problem

What needed solving

Microalgae production is currently too expensive for mass market use. Simultaneously, soilless farms struggle with nutrient-rich wastewater that causes environmental damage.

The solution

What was built

A decentralized production system featuring photobioreactors, A.I. predictive models, cloud monitoring, and a direct air capture prototype for CO2.

Target: Bio-pesticide and biostimulant producers

If you are a chemical company dealing with the demand for greener alternatives — this project developed a biorefinery approach to create high-demand biostimulants and biopesticides from algae.

Frequently asked

Quick answers

How does this affect the production cost of microalgae?

The project expects to reduce microalgae production costs by >50% by utilizing free nutrients from agricultural wastewater and optimizing inputs like energy and labor.

Is this technology tested at an industrial scale?

Yes, the project is deploying two validation facilities in the Netherlands and Finland, and two demonstration facilities in Portugal and Spain near soilless greenhouses.

What is the IP or licensing status of the technology?

Based on available project data, specific licensing terms are not mentioned, but the project focuses on developing a replicable business model for EU-wide installation.

How is the production managed to ensure efficiency?

Production is managed via novel sensors, A.I.-based predictive models, and a cloud-based monitoring system to maintain a continuous harvest regime.

What is the timeline for the project's completion?

The project period runs from July 1, 2022, to June 30, 2026.

Consortium

Who built it

The consortium is strongly geared toward commercialization with a 38% industry ratio, comprising 6 companies (including 5 SMEs) and 9 research-oriented partners. This balance ensures that the technical development of A.I. sensors and biorefinery processes is directly linked to market needs in the agriculture and aquaculture sectors across 7 European countries.
