A European research initiative focused on developing sustainable algae-based products is making significant progress toward transforming the future of textiles, fashion and other industries. The Locality project, launched in 2023, is advancing multiple algae-based value chains aimed at creating environmentally responsible alternatives to conventional materials and supporting the transition to a circular economy.
The project recently achieved a major milestone by successfully producing an algae-based aquafeed prototype on an
industrial scale. The feed will undergo farm-scale testing in Norway between August and October 2026, marking an important step in demonstrating the commercial viability of algae-derived products beyond laboratory environments.
While aquaculture remains one of the project’s key focus areas, Locality is also driving innovation in the textile sector through the development of algae-based dyes, fibers and textile additives designed to reduce the industry’s environmental footprint.
Established to support sustainable algae value chains across countries bordering the Baltic and North Seas, the initiative aims to accelerate the commercialization of innovative products derived from algal biomass. Alongside textiles, the project is exploring applications in food, aquaculture feed, biofertilizers, biostimulants and nutraceuticals.
One of the most promising developments highlighted by the project is the growing potential of algae as a sustainable raw material for fashion and textile production. In a recent report, Locality described algae as a potential game-changer for sustainable fashion due to its ability to provide renewable, biodegradable and low-impact alternatives to conventional textile materials.
Innovations such as Algaeing’s biodegradable algae-based dye formulations and SeaCell, a fiber derived from seaweed, demonstrate how marine resources can contribute to more sustainable textile manufacturing. Researchers are also exploring alginate, extracted from brown macroalgae, as a natural substitute for traditional textile materials.
The project has further investigated the use of pigments derived from both macroalgae and microalgae. These naturally occurring colorants could replace synthetic dyes and chemicals commonly used in textile processing, helping manufacturers reduce pollution and resource consumption.
As part of the research effort, project partner Mounid, a Swedish material innovation startup specializing in bio-based textile dyes derived from microalgae, collaborated with the University of Borås in Sweden to develop and test an algae-based dye formulation. The project successfully produced a visually appealing blue shade that bonded effectively with cellulosic fabrics. The dyed material was subsequently used to create a kimono, demonstrating the practical application of algae-derived colorants in fashion products.
Despite these encouraging developments, researchers acknowledge that several challenges remain before algae-based textiles can achieve large-scale commercial adoption. Key areas requiring further study include identifying the most suitable algae species, improving dyeing techniques and ensuring that algae-based textiles meet industry requirements for durability, color fastness and long-term performance.
Locality researchers believe continued investment in research, testing and industrial collaboration will be essential to unlocking the full potential of algae as a sustainable resource for the textile industry.
As global fashion brands increasingly seek environmentally responsible materials and production methods, algae-based fibers and dyes could play an important role in reducing reliance on fossil-fuel-derived chemicals while supporting the industry’s sustainability goals.
With growing momentum behind circular and bio-based materials, the Locality project is positioning algae as one of the most promising resources for the next generation of sustainable textile innovation.
