A pioneering bio-textile crafted from marine algae has been rolled out by the Fashion Commission of Saudi Arabia at the Misk Global Forum in Riyadh, marking a bold step into sustainable fashion. The initiative, termed the Red Sea Seaweed Project, turns algae harvested from the Red Sea into fabric through a collaboration with King Abdullah University of Science and Technology and the fibre-specialist PYRATEX. The unveiling took place during a panel titled“Fabric of the Future: Red Sea Seaweed Textile” and was led by the commission's CEO Burak Çakmak.

The textile is created by integrating seaweed biomass with Lyocell and organic cotton to form a sustainable fibre. Py­ra­tex's expertise in seaweed-based fabrics-previously applied in other regions-has been adapted here for local algae species. The venture relies on KAUST's research unit KAUST Beacon Development to harvest Red Sea algae while maintaining its bioactive properties and supporting a traceable supply chain. Çakmak said the material“marks a defining moment in our journey to build a future-ready sustainable fashion ecosystem. By transforming a local natural resource into a fully traceable, sustainable textile, we are demonstrating the power of science, creativity and industry working together.”

KAUST's involvement builds on its broader algal biotechnology work, including the DABKSA initiative set up with the Ministry of Environment, Water and Agriculture to establish local algae-based industries. That scheme originally focused on animal feed, but now its marine-species work is feeding into fashion applications. PYRATEX's page confirms seaweed-based fabrics offer anti-irritation and skincare benefits-though that model was previously developed in Iceland.

The project is designed not only as a material innovation but as a symbol of economic diversification. The Fashion Commission says it aims to strengthen the Kingdom's domestic fashion ecosystem by embedding sustainability principles and leveraging local resources. The Lab, the commission's in-house development studio, converted the seaweed fibre into wearable garments, emphasising full supply-chain transparency.

Analysts note that the fashion industry globally is under rising pressure to reduce its environmental footprint. The Guardian estimated the sector accounts for up to 10 per cent of global greenhouse-gas emissions. By tapping coastal biomass, the Saudi initiative could offer a distinct regional advantage. The Red Sea region's marine environment provides access to algae species adapted to high salinity and heat, meaning less intensive cultivation may be required. KAUST's earlier trials with extremophile algae in desert conditions underline that point.

However, questions remain about how the new textile will scale commercially and how its sustainability claims will hold in full life-cycle analyses. Industry watchers emphasise that adopting bio-based textiles is only part of the solution; supply-chain energy use, water consumption, and end-of-life recyclability also matter. The Fashion Commission acknowledged those challenges in its public statement but noted this is a“first step” in a broader innovation roadmap.

Beyond the material itself, the move aligns with broader strategic priorities such as Vision 2030 and the Saudi Green Initiative, which call for economic diversification and sustainable development across the Kingdom. It also positions Saudi fashion as a player in the global sustainability agenda, where brands are looking for story-driven innovation and regional supply-chain transparency. The Fashion Commission's statements emphasise that this home-grown development can contribute meaningful solutions to the global fashion landscape.
