Presentation

Sustainable polyesters equivalent to petro-sourced, pull low LCA recycling.

Sustainable PET must couple recycling or biosource technologies with favorable Life Cycle Assessment during tire reinforcement use. To days properties of textile, from the microstructure to the tire performance, are unchanged by recycling, whether mechanical from clear bottle limited feedstock or chemical from varied origins. The Michelin Group's targets of 40% sustainable materials by 2030 and 100% by 2050, pull new technologies, matured by WHITECYCLE European project lead by Michelin.
