Renasens, a Sweden-based developer of proprietary waterless textile recycling technology, has raised €10M ($11.5M) in seed funding led by Extantia. The process uses supercritical CO₂ to remove dyes and chemicals from blended textile waste, separating fibers like polycotton intact for high-quality recycled materials. The capital will fund construction of an industrial pilot plant in Borås, Sweden.
EU Mandates Fuel Chemical Recycling Surge
The raise aligns with EU regulations mandating separate textile collection from 2025. Swedish peer Syre announced a multi-year Nike partnership after its $100M Series A. Renasens targets polycotton blends, which current methods struggle to recycle without degradation. Its modular design integrates into existing facilities, lowering scaling barriers.
Blended Waste Defies Mechanical Recycling
Post-consumer textile waste, dominated by polycotton blends, lands in landfills due to inseparability. Mechanical recycling degrades fibers, while traditional chemical methods dissolve them entirely. Blended textiles represent the most common yet unwanted waste fraction, structurally challenging industrial recycling.
Supercritical CO₂ Preserves Fiber Integrity
Renasens' technology employs supercritical CO₂ to extract dyes, PFAS, and chemicals without water or harsh solvents. This achieves 98% separation efficiency for polycotton with only 3-5% fiber strength loss, producing intact fibers rivaling virgin quality. Unlike competitors that depolymerize, the process 'renovates' fibers, enabling cost-competitive circular production.
As Dr. Jade Bouledjouidja, CEO and founder, explained:
"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."
Deeptech Investors Back Founder-Led Scaleup
Extantia led the round, joined by Course Corrected and Norrsken Launcher, marking Europe's largest hardware seed in 2026. Investors prioritize 'founder first' bets on deeptech infrastructure. Carlota Ochoa Neven Du Mont of Extantia called Renasens "a piece of strategic European infrastructure… at a green discount."
Textile Recycling Market Scales to $11.9B
The global textile recycling market stands at $8.41B in 2025, projected to reach $11.88B by 2030 at 7.2% CAGR. Chemical recycling gains traction for handling blends amid EU waste directives. Swedish cluster including Syre and Circulose drives innovation, with government meetings signaling infrastructure support.
PhD Founder Pioneers CO₂ Textile Tech
Founder Jade Bouledjouidja holds a PhD in Materials Sciences from Aix-Marseille University, with prior R&D leadership at FineCell (nanocellulose) and Trifilon (biocomposites). Her supercritical fluid expertise, honed in drug delivery, adapted to textiles during solo lab validation. COO Nora Eslander brings cleantech marketing from Colorifix.
Pilot Launch Accelerates Europe Expansion
Renasens broke ground on its Borås pilot site and already supplies fibers to manufacturers in Portugal and Italy. Plans include licensing technology in Spain and France. Recent hiring targets engineers and chemists to industrialize the modular reactors.
