Syntetica nylon recycling funding of $30 million has drawn in Lululemon, Sri Lankan apparel manufacturer MAS Holdings, and a clutch of European public investors, as the French startup bets that cost-competitive chemistry can do what sustainability pledges alone have not: actually close the loop on one of fashion’s most persistent materials.
A Patented Process That Solves Sorting
The core problem Syntetica addresses is unglamorous but stubborn. Nylon 6 and Nylon 6,6 dominate the synthetic textiles market, but the two variants cannot easily be separated once they reach consumer waste streams. Most recycling infrastructure simply gives up at that point. WWD reports that Syntetica’s patented process handles both types in a single operation, producing what The Business of Fashion describes as virgin-quality recycled nylon.
The output is not yarn or finished fabric. It is pellets, an intentional choice. Syntetica positions itself as a supplier to the existing supply chain rather than a competitor within it, letting manufacturers such as MAS convert those pellets into yarn themselves.
‘It’s a story of pragmatic industrial partnerships with the right players to get buy-in from the whole value chain,’ chief executive Marco Bertone told TechCrunch.
Syntetica Nylon Recycling Funding: Who Backed the Round and Why
The Series A was led by the Ecotechnologies 2 fund, managed by the Green Venture team at Bpifrance, France’s public investment bank. Ecotechnologies 2 launched in 2022 with €300 million, targeting late Series A rounds in companies developing technologies with strong environmental impact, according to Maddyness. The investment forms part of the broader France 2030 plan, through which Bpifrance acts as a direct equity financier for the first industrialisation of innovative technologies.
The European Innovation Council (EIC), whose 2025 work programme allocates over €1.4 billion across grants, blended finance, and equity for startups and scaleups, also contributed equity and grant support alongside its acceleration programme, according to the EIC’s 2025 work programme. Private backers include EQT Ventures, SWEN Capital Partners, and family offices.
MAS Holdings, one of the world’s largest apparel manufacturers, is also a Series A investor. Bertone characterised the participation as ‘a recognition of how significant the problem has become,’ noting that supply chain actors rarely back startups at this stage. Victoria’s Secret and Etam are listed as brand partners, with a recycling project that could reach market early next year.
Before the round closed, Syntetica had already secured a partnership with Michelin’s Centre for Sustainable Materials to build a commercial demonstration facility in Clermont-Ferrand, the industrial city in central France where Michelin is headquartered. The $30 million will now be used to advance that facility toward processing hundreds of tons of textile waste annually.
Geopolitics has sharpened the commercial case. In the past six months, turbulence in oil markets drove nylon price renegotiations to a quarterly or even weekly cadence. ‘It’s been a wake-up call to many brands that have been relying on petrol-sourced nylon and petrol-sourced synthetics for pricing and convenience, and which today have seen massive shocks to their system,’ Bertone said. For brands accustomed to stable synthetic-fibre costs, a domestic, waste-fed supply starts to look less like idealism and more like insurance.
Bertone was clear that the company was never built around a green premium. ‘We have built the company with the clarity that there’s no green premium. That if you want to scale real solutions for a sustainable world, it needs to be cost competitive, highly scalable, and you need to build partnerships from the very start,’ he said.
The founding team reflects that pragmatic streak. Bertone comes from fashion and second-hand e-commerce. He met co-founder Louis Monsigny, a chemistry researcher, through the Entrepreneur First accelerator at Paris’s Station F campus. The pair subsequently used AgroParisTech’s lab in Reims to develop the core technology. Chief technology officer Ash Ward joined later; Ward previously worked for Northvolt, the battery company that collapsed into insolvency. Peter Carlsson, Northvolt’s co-founder, sits on Syntetica’s advisory board. Bertone sees that background as an asset: people who have watched a scaling company fail know precisely which risks to avoid stacking on top of each other.
Syntetica has competitors, among them BASF and startups using enzymatic degradation. Bertone’s view on them is direct: ‘If everyone were to scale to tens of factories, we still wouldn’t solve this problem. Everyone needs to succeed for us to succeed as a society.’
The immediate milestone that will shape the company’s next chapter is the Clermont-Ferrand demonstration facility. If it delivers pellets at commercial scale, Bertone’s stated ambition is a network of plants built close to waste sources and textile-production hubs around the world. The demonstration run, in other words, is the only number that matters right now.
