ALLGAE - 100% algae-based textile fibers

In the research project ALLGAE, 100% algae-based textile fibers are being developed from side streams of seaweed. Additionally, a new algae pigment will be integrated into an efficient one-step process during fiber spinning. These innovative fibers have the potential to replace conventional fossil- and bio-based fibers while eliminating the need for harmful textile dyes.

Today, seaweed and algae are primarily used in the food industry, but with increasing production, there are significant opportunities to explore new applications. Moreover, side streams are generated that cannot be used as food but serve as valuable raw materials for producing bio-based materials such as textiles and bioplastics.

The textile industry accounts for as much as 10% of global carbon dioxide emissions. By developing sustainable textile products based on local raw materials, such as algae, resource use can be optimized, and emissions significantly reduced. A successful concept can also increase the value of seaweed and algae biomass, particularly their side streams, contributing to both economic and environmental sustainability.

In ALLGAE, producers of refined seaweed and algae-based dye, known as "algae ink," collaborate with researchers and experts in fiber development and color formulation. Together with a partner in outdoor apparel, the project explores potential product segments and develops a circular and sustainable value chain for algae-based textiles. The work also includes needs, sustainability, and market analysis, as well as dissemination of project results.

ALLGAE is funded by Formas and is a collaboration between Chalmers Industriteknik, Manatee Biomaterials, MOUNID, RISE, and Houdini Sportswear.

The project runs from December 2024 to November 2026 and is coordinated by Chalmers Industriteknik.
