Renasens, a Stockholm-based deeptech company developing textile recycling technology, has raised €10 million in a seed funding round led by Extantia, with participation from Course Corrected VC and continued backing from Norrsken Launcher.
Renasens is addressing a structural challenge in the textile industry, where more than 12 million tonnes of 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.
The company aims to close this gap by enabling fibre-to-fibre recycling at scale and reducing reliance on imported virgin materials.
Its platform uses modified supercritical CO₂ to separate and decolour blended textiles, recovering intact fibres without the use of water or the use of toxic chemicals. The recovered materials can be reintroduced into existing manufacturing processes without requiring new equipment, and the system is designed to be modular, allowing deployment within existing facilities across fragmented supply chains.
Post-consumer textile waste has long been considered both technically and structurally unsolvable. We have developed a process that makes fibre recycling viable at industrial scale, and are now building the infrastructure and partnerships to support its adoption across Europe,
said Dr Jade Bouledjouidja, founder and CEO of Renasens.
The company has already begun supplying recovered cotton and polyester fibres to manufacturers in Portugal and Italy. Its development comes as EU regulations tighten, with mandatory textile collection systems introduced in 2025 and extended producer responsibility schemes are 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.
