CLERMONT-FERRAND, France: Plastic waste recycler Carbios has successfully tested its enzymatic process to create “high tenacity” tire fibres for Michelin.
The company says the fibre is particularly suitable for tires, due to its breakage resistance, toughness and thermal stability.
Carbios uses an enzyme capable of depolymerizing the PET (Polyethylene Terephthalate) contained in various plastics or textiles to allow infinite recycling of all types of PET waste. It also allows the production of 100 percent recycled and 100 percent recyclable PET products with the same quality as if they were produced with virgin PET.
“We are very proud to be the first to have produced and tested recycled technical fibres for tires,” said Nicolas Seeboth, director of Polymer Research at Michelin. “These high-tech reinforcements have demonstrated their ability to provide performance identical to those from the oil industry.”
Michelin is committed to achieving 40 percent sustainable materials of renewable or recycled origin by 2030 and 100 percent by 2050 as part of a bid to establish a circular economy for tires.
Every year manufacturers sell 1.6 billion car tires worldwide that include 800,000 tonnes of PET that could be recycled into technical fibres for Michelin.
Carbios Chief Scientific Officer Alain Marty said his company first produced bottles from the enzymatic recycling of post-consumer PET waste in 2019. This has now been extended to recycling the same type of PET waste for tire production.
