Syntetica

Syntetica is a Paris-based deeptech company that uses green chemistry to transform mixed textile waste into virgin-quality recycled nylon polymers. Founded in 2023 by CEO Marco Bertone and CTO Louis Monsigny through the Entrepreneur First accelerator, the company developed a patented low-temperature, low-pressure process capable of recycling both Nylon 6 and Nylon 6,6 from blended post-consumer textiles in a single step, eliminating the sorting barrier that has kept most nylon apparel out of circular supply chains.

Nylon's durability makes it indispensable in activewear, automotive, and high-performance textiles, but also among the hardest materials to recycle at scale. Syntetica's catalyst-driven molecular separation recovers nylon from elastane, cotton, and other fiber blends, producing drop-in recycled polymers for brands including Lululemon, Victoria's Secret, Etam, and manufacturing partners like MAS Holdings — moving mixed nylon waste from landfill toward industrial-scale circular production.
