With a set of standard tires for a car, around 40 recycled PET bottles are given a second life. The new material will initially be used in the two Continental summer tires PremiumContact 6 and EcoContact6 as well as in the all-season tire AllSeasonContact.
Recycling is to be expanded further
“We only use high-performance materials in our premium tires. This now also includes polyester yarn made from particularly efficiently recycled PET bottles,” says Ferdinand Hoyos, who heads Continental’s tire replacement business in Europe, the Middle East and Africa. “We are constantly expanding the proportion of renewable and recycled materials in our tires. We want to use only sustainable materials in our tire production by 2050 at the latest.”
procedure is particularly efficient
The ContiRe.Tex process was presented back in September 2021. The polyester yarn can thus be obtained from used PET bottles without any special intermediate chemical steps. This makes it more efficient than other previously known methods of processing plastic bottles into polyester yarns. After mechanical shredding, it is further processed into the base material PET granulate, which is then extruded and spun into threads.
Recycled yarn in the tire sidewall: Corresponding products receive a “Contains Recycled Material” label.
The tires with ContiRe.Tex technology have a corresponding logo on the sidewall (“Contains Recycled Material”). For the second season of the electric racing series Extreme E, which started in February 2022, Continental has developed a tire that also uses ContiRe.Tex. The support vehicles for this year’s Tour de France will also be equipped exclusively with ContiRe.Tex tires.
