Renasens, a Stockholm-based deeptech company, has raised €10 million in a seed funding round led by Extantia, with participation from Course Corrected VC and continued backing from Norrsken Launcher.

Innovative Textile Recycling

Renasens is addressing a crucial challenge in the textile industry: more than 12 million tonnes of textile waste are generated annually in Europe, yet less than 1 per cent is recycled into new fibres. Existing recycling methods struggle to process blended and treated fabrics, which makes up the majority of post-consumer waste.

Renasens' platform uses modified supercritical CO₂ to separate and decolour blended textiles, recovering intact fibres without the use of water or toxic chemicals. The recovered materials can be reintroduced into existing manufacturing processes without requiring new equipment. The system is designed to be modular, allowing deployment within existing facilities.

Expansion and Regulatory Compliance

Renasens has already begun supplying recovered cotton and polyester fibres to manufacturers in Portugal and Italy. This development comes as EU regulations tighten, with mandatory textile collection systems introduced in 2025 and extended producer responsibility schemes expected by 2027, increasing demand for scalable recycling solutions.

The funding will support the development of a pilot plant in Borås, Sweden, and enable the company to begin supplying recovered fibres directly into European manufacturing.
