Syntetica Raises $30 Million to Solve Nylon's Recycling Problem

Syntetica, a French recycling startup, has raised $30 million in Series A funding led by Ecotechnologies 2, with participation from Lululemon and Asian apparel manufacturer MAS Holdings, to commercialise a chemical process for recovering virgin-quality nylon from mixed textile waste. The funding will build the company's first commercial facility in France, capable of processing hundreds of tonnes of post-consumer textile waste annually, following a pilot facility established two years ago. The round also drew public backing from Bpifrance and the European Innovation Council.

 

Why Nylon Has Resisted Recycling

 

Nylon is the second-most-used synthetic fibre globally behind polyester, reaching roughly 7 million tonnes in 2024 according to Textile Exchange, and it is particularly important to sports, swimwear and performance apparel brands that rely on its durability. Despite that scale, nylon remains sparsely recycled, and the reason lies in how it typically reaches the waste stream: most post-consumer nylon sits within blended fabrics, woven or knitted together with materials such as elastane, cotton and polyester rather than existing as a pure, single-material textile.

Conventional recycling technologies generally require extensive pre-sorting to separate different fibre types before processing, a step that becomes prohibitively difficult and expensive when the fibres are physically interwoven at the textile level rather than simply mixed in a pile of garments. That technical barrier has left the majority of nylon in circulation effectively unrecoverable through standard recycling methods, despite the material's abundance and value.

How Syntetica's Process Works Differently

 

Syntetica's proprietary chemical recycling process recovers the two most widely used forms of nylon directly from mixed textile waste, without requiring the pre-sorting step that limits conventional approaches. That capability to process blended fabrics containing elastane, cotton and polyester alongside nylon is the core technical breakthrough the company is commercialising, since it removes the sorting bottleneck that has kept blended nylon textiles largely outside the recycling system.

Chemical recycling, as distinct from mechanical recycling that simply shreds and reprocesses materials physically, breaks fibres down at the molecular level and rebuilds them, which is generally what allows recovery of a specific polymer like nylon from a fabric blend containing several different fibre types. Producing output the company describes as virgin-quality suggests the recycled nylon can substitute directly for newly manufactured material in performance applications, rather than being downgraded to lower-value uses, which is typically necessary to justify adoption by brands unwilling to compromise on fabric performance.

Why the Timing Aligns With Regulatory Pressure

 

Syntetica is already working with brands including Victoria's Secret and Etam, and the company points to upcoming European regulation, including extended producer responsibility rules and the Ecodesign for Sustainable Products Regulation, as likely to push minimum recycled content requirements into apparel manufacturing. That regulatory trajectory changes the commercial calculation for fashion brands considerably: rather than sourcing recycled nylon as a voluntary sustainability initiative, brands may soon be required to meet recycled content thresholds by law, converting recycled fibre from a marketing differentiator into a compliance necessity.

That shift explains the investor mix backing this round. Lululemon and MAS Holdings, both directly exposed to nylon-dependent product categories, have a commercial incentive to secure reliable recycled fibre supply ahead of regulatory deadlines, rather than scrambling for compliant material once requirements take effect. Whether Syntetica's first commercial facility can scale processing volumes fast enough to meet the recycled content demand regulation is expected to generate, and whether its chemical process maintains quality and cost competitiveness at industrial scale beyond pilot operations, will determine whether the company becomes a significant supplier to an industry facing mounting pressure to secure scalable recycled fibre sources.
