Salt & Fiber, a cleantech startup based in Malmö, Sweden, has secured €300,000 in pre-Seed funding to advance its technology that converts beach-cast seagrass into sustainable textile yarns. Alongside the investment round, the company has simultaneously launched a €45,000 crowdfunding campaign to support its scaling efforts.
The startup addresses a dual challenge facing European coastal regions and the textile industry. Municipalities across Sweden and beyond currently landfill significant quantities of seagrass that washes ashore, creating waste management costs and environmental concerns. Simultaneously, conventional textile production remains resource-intensive, requiring substantial freshwater consumption, synthetic fertilizers, and agricultural land.
Transforming Coastal Waste into Production Assets
Salt & Fiber’s approach utilizes naturally occurring seagrass as a raw material for creating biodegradable, plant-based textile fibres. The resulting yarns require no fresh water, fertilizers, or land during production—a significant departure from traditional fiber manufacturing. This circular economy model converts what municipalities classify as waste into a valuable production input.
The company has already progressed beyond the concept stage. Salt & Fiber currently operates in pilot production and has secured a supply agreement with a Swedish municipality, validating both the technical feasibility and market demand for its solution. The startup is also part of the Älmhult x IKEA incubator programme, providing access to expertise and networks within the established furniture and textile sectors.
Timeline and Market Readiness
Salt & Fiber targets commercial market entry between 2027 and 2028, indicating a realistic scaling timeline for technology validation and production capacity development. The newly secured funding will support both production scaling and the commercialization phase required to establish market presence.
The convergence of the pre-Seed investment and crowdfunding campaign suggests a hybrid funding strategy designed to both secure institutional backing and validate consumer and business-to-business interest in the product. This dual approach has become increasingly common among European cleantech startups seeking to demonstrate market traction alongside capital efficiency.
Growing Momentum in Sustainable Textiles
Salt & Fiber’s progress reflects broader momentum within the European startup ecosystem toward solving sustainability challenges in fashion and textiles. The sector has attracted increasing investor attention as regulatory pressures intensify around textile waste, microplastics, and water consumption across the EU.
Swedish cleantech startups have established particular prominence in developing resource-efficient production methods, leveraging the country’s existing sustainability focus and manufacturing infrastructure. Salt & Fiber’s positioning—combining waste valorization with production scalability—aligns with investor priorities in circular economy solutions that address both environmental and operational efficiency concerns.
The startup’s participation in established incubator networks and its municipal supply partnerships suggest a market-driven approach rather than speculative technology development, factors that often appeal to both institutional investors and crowdfunding supporters seeking demonstrated viability.
