CARBIOS enters the r-PET market for tire textile filaments

21 Jul 2025 17:45 CEST

• 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.
