Description

Carbios, and partner of the foundation, Michelin, are a major step closer to achieving a world-first in the tire sector. Michelin have successfully validated the use of Carbios’ enzymatic recycling technology for PET plastic waste in its tires – the testing marks a new step towards 100% sustainable tires. Carbios’ enzymatic recycling process uses an enzyme capable of depolymerizing the PET contained in various plastics or textiles (bottles, trays, polyester clothing, etc.). This major step confirms the potential of Carbios’ process to engage the industry in a responsible transition towards a sustainable circular economy model.

Impact & Result

Carbios’ enzymatic recycling process therefore enables Michelin to get one step closer to its sustainable ambitions, and contributes to the entry of tires into a true circular economy. Michelin is committed to achieving 40% sustainable materials (of renewable or recycled origin) by 2030 and 100% by 2050.

Solution Spotlight

Technology provides an industrial solution to the recycling of PET plastics and textiles (the dominant polymer in bottles, trays, and textiles made of polyester). The enzymatic recycling technology developed by Carbios deconstructs any type of PET plastic waste into its basic components, which can then be reused to produce new PET plastics of a quality equivalent to virgin ones. This innovation, the first of its kind in the world, was recently recognized in a scientific paper published in the prestigious journal Nature.
