Stockholm-based deeptech startup Renasens has raised €10 million in a seed round led by Extantia, with participation from Course Corrected VC and continued backing from Norrsken Launcher, as it looks to scale its CO₂-based textile recycling technology across Europe. The company is tackling a persistent bottleneck in the industry—processing blended and treated fabrics—by using modified supercritical CO₂ to separate and recover fibres without water or toxic chemicals, enabling fibre-to-fibre recycling compatible with existing manufacturing systems. The newly raised capital will be used to build a pilot plant in Borås and expand partnerships with European manufacturers, as well as to begin supplying recovered cotton and polyester fibres at scale in response to tightening EU textile waste regulations.
Renasens develops scalable solutions for textile and agricultural waste recycling, founded in 2022. The female-led startup has built a proprietary, waterless recycling process that separates and recovers high-quality fibres from both pure and blended materials without degrading their performance, while also removing dyes and chemical additives. Designed to be energy-efficient and modular, the technology integrates into existing industrial infrastructure, enabling fibre-to-fibre recycling at scale without the need for new production systems.
“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,” says Dr Jade Bouledjouidja, founder and CEO of Renasens.
Positioning itself at the intersection of materials science and circular manufacturing, Renasens works with partners across the textile value chain—from recyclers to manufacturers—to reintroduce recovered cotton and polyester into production loops.
The company aims to recycle 100,000 tonnes of mixed textile waste by 2030, addressing key environmental challenges including landfill overflow, microplastic pollution, and water contamination, while supporting the fashion industry’s transition toward a circular economy.
