CARBIOS enters the r-PET market for tire textile filaments

• CARBIOS has signed a multi-year commercial agreement with Indorama Ventures, the world leader in polyester production. CARBIOS will supply recycled monomers that will be transformed into filaments by Indorama Ventures, intended for use in tire reinforcement for Michelin.
• This new commercial agreement highlights the interest of a new market—industrial fabrics—for high-quality r-PET derived from enzymatic recycling.

Clermont-Ferrand (France), 21 July 2025 (17h45 CEST) – CARBIOS (Euronext Growth Paris: ALCRB) announces the signing of a multi-year commercial agreement with Indorama Ventures, the global leader in PET production. This agreement covers the supply of biorecycled monomers from its Longlaville plant, which will be transformed into r-PET filaments by Indorama Ventures and then integrated by Michelin into the manufacturing of its tires.

A strategic commitment to turn complex PET waste into high-performance materials

Thanks to its enzymatic PET recycling technology, CARBIOS will produce monomers from complex PET waste at its future industrial site in Longlaville. Indorama Ventures will handle the repolymerization and production of technical filaments. Michelin will use these innovative materials in its tire reinforcements.

A new milestone in the pre-commercialization of the Longlaville plant

This commercial agreement is part of the pre-commercialization momentum of CARBIOS’ future industrial site, just weeks after signing the first sales contracts for biorecycled PET with two global cosmetics leaders.

Vincent Kamel, CEO of CARBIOS: “This commercial agreement with Indorama Ventures marks a new step in the realization of our industrial project. It confirms the trust of Indorama Ventures and Michelin in our PET biorecycling technology. Alongside the commercial successes already achieved in cosmetic packaging applications, this agreement illustrates our ability to deliver innovative solutions to the most demanding industries, particularly industrial filaments for tire applications and, more broadly, textile.”

Fabien Gaboriaud, Director of Circularity and Renewable & Recycled Materials at Michelin Group: “This partnership is a tangible expression of our commitment to turning complex waste into high-performance materials. By integrating enzymatically recycled r-PET into our tires, we are marking a new milestone on our journey toward achieving 100% renewable and recycled materials by 2050 — all while staying within planetary boundaries. It is by combining innovation, industrial excellence, and close collaboration with trusted partners that we are building a strong and lasting circular model.”

Renato Boaventura, Global Market Head Mobility at Indorama Ventures, confirms the long-standing relationship and close collaboration with Michelin on more sustainable solutions. “This alliance with both, CARBIOS and Michelin, underlines our commitment to plan ahead and take a leading role in shifting the industry towards circularity”, he said.
