Circular Algae Production Using Industrial Waste for Food, Feed, and Textiles

environmentTestedTRL 5

Imagine turning the waste from greenhouses or fish farms into a goldmine for growing algae. This project cleans up the ocean and industrial runoff by using that waste as fertilizer for seaweed and microalgae. These algae are then processed into useful ingredients for things like plant-based proteins, fish feed, and fabric dyes.

The business problem

What needed solving

Industries like greenhouse production and fish processing create nutrient-rich waste streams that are costly to manage. Simultaneously, the food and textile markets lack sustainable, bio-based alternatives to synthetic ingredients.

The solution

What was built

Biorefinery pipelines and algae-based formulations for food, aquafeed, agriculture, and textiles. The project also created three regional industrial ecosystems for waste-to-biomass conversion.

Who can put this to work

Food & Beverage
any
Target: Alternative protein manufacturer

If you are a protein producer dealing with high raw material costs — this project developed algae-based ingredients that provide sustainable protein alternatives. These are derived from biorefinery pipelines using waste streams.

Aquaculture
SME
Target: Fish feed producer

If you are a feed company dealing with unsustainable ingredient sourcing — this project developed functional algae ingredients for aquafeed. These are produced by recycling nutrients from fish processing waste.

Textiles
mid-size
Target: Sustainable fashion brand

If you are a textile manufacturer dealing with toxic chemical dyes — this project developed algae-based dyes and anti-bacterial ingredients. These are sourced from North and Baltic Sea ecosystems.

Frequently asked

Quick answers

What is the cost or price of the algae products?

Based on available project data, specific pricing or cost-per-unit information is not provided; however, the project is integrating these into a business model for market implementation.

Can this be scaled to an industrial level?

Yes, the project has already demonstrated cultivation potential for tested waste streams and the set-ups are currently being upscaled.

How is the IP and licensing handled?

Based on available project data, specific licensing terms are not listed, but the project involves 15 industry partners and 13 SMEs to prepare for market exploitation.

What regulations affect these products?

The project is specifically identifying significant constraints and legal barriers to ensure the business model allows for successful market implementation.

When will the products be available for purchase?

The project runs until 2027-05-31, with the goal of gaining a strong position in the European marketplace in the coming years.

Consortium

Who built it

The consortium is heavily weighted toward commercial application, with a 54% industry ratio comprising 15 companies, 13 of which are SMEs. This strong industrial presence, spanning 14 countries, suggests a high focus on market viability and a broad European distribution network for the resulting algae products.
