HANOVER, Germany—Continental A.G. has launched volume production of passenger tires using polyester yarn in the carcass derived from waste polyethylene terephthalate (PET).
The new "ContiRe.Tex" technology uses recycled polyester yarn obtained from post-consumer PET plastic bottles and "completely replaces the conventional polyester in a tire carcass," Conti said.
A set of standard tires, for instance, features around 40 recycled PET bottles, Conti said.
The high-performance material is first being used in selected sizes for Continental's PremiumContact 6 and EcoContact 6 summer tires.
Continental said it unveiled the ContiRe.Tex technology in August last year and brought the technology to production stage within eight months.
