Continental to use recycled PET bottles in its tire production starting in 2022
Hanover, Germany – Continental enables the use of reprocessed polyester obtained from recycled plastic bottles in its tire production as of 2022. The new sustainable polyester yarn will be obtained from polyethylene terephthalate (PET) bottles by a mechanical process and will be used in the construction of the tire carcass. This can completely replace conventional polyester. Together with its cooperation partner and supplier OTIZ, a fiber specialist and textile manufacturer, the premium tire manufacturer has developed a special technology to recycle PET bottles without previously necessary intermediate chemical steps and to make the polyester yarn functional for the high mechanical requirements of the tire. In the course of so-called upcycling, a PET bottle becomes a high-performance PET material.
“As early as 2022, we will be able to use material obtained from recycled PET bottles in tire production. In our innovative recycling process, the fibers are spun from recycled PET without having to break the material down into its components beforehand,” says Dr. Andreas Topp, responsible for materials, process development and industrialization in Continental’s Tires business area. He adds: “Already at this year’s IAA MOBILITY in Munich, we will present a highly innovative concept tire with polyester yarn made from recycled PET bottles. With the use of recycled polyester yarn, we are taking another important step in the direction of cross-product circular economy.”
