Turning Algae Industrial Waste into High-Value Food, Feed, and Cosmetic Ingredients

foodPilotedTRL 6

Imagine a factory that makes seaweed jelly but throws away 70% to 85% of the algae it uses. This project finds a way to stop that waste by using water-based cleaning and extraction to pull out proteins and nutrients from the leftovers. It's like turning the scraps from a kitchen into gourmet meals and skincare products.

The business problem

What needed solving

Algae industries currently waste between 70% and 95% of their biomass, losing significant potential revenue and creating environmental waste.

The solution

What was built

Three pilot-scale biorefinery schemes and 12 demonstrator products for the food, feed, and cosmetic sectors.

Who can put this to work

Plant-based Food
any
Target: Vegan food manufacturer

If you are a vegan food manufacturer dealing with a lack of high-quality protein sources — this project developed texturized vegan food ingredients that improve product structure and nutrition using algae waste.

Animal Nutrition
mid-size
Target: Aquaculture or livestock feed producer

If you are a feed producer dealing with expensive raw material costs — this project developed protein-rich feeds derived from industrial algae streams to lower costs and increase sustainability.

Cosmetics
SME
Target: Skincare brand

If you are a skincare brand dealing with the need for natural, bioactive ingredients — this project developed topical cosmetic formulations using bioactive molecules extracted from algae residuals.

Frequently asked

Quick answers

What is the industrial scale of the production process?

The project has demonstrated three blue biorefinery schemes up-scaled to process hundreds of kilograms of algae waste streams.

How does this affect the cost of raw materials?

By transforming waste streams that currently make up to 95% of initial biomass into value-added ingredients, the project aims to make algae industries more economically viable.

What is the status of IP and licensing for these ingredients?

Based on available project data, specific licensing terms are not listed, but the project involves 15 industry partners and 11 SMEs to validate market readiness.

Are these products compliant with food and cosmetic laws?

The project specifically connects industry partners with RTOs to validate regulatory compliance and health-promoting claims.

When will these products be available on the market?

The project runs until 2026-09-30, with two final products currently being qualified for market and consumer acceptance.

Consortium

Who built it

The consortium is heavily industry-driven, with 15 industrial partners (65% of the total) and 11 SMEs across 11 countries. This high ratio of commercial entities compared to only 3 universities and 2 research organizations suggests a strong focus on commercial viability and market integration rather than pure academic research.
