IAA2021 – Continental unveils GreenConcept tyre

Organic materials used include natural rubber from dandelions and silicate from the ashes of rice husks.

Continental is presenting its GreenConcept tyre at this week’s IAA in Munich.

The supplier says at more than 50%, the tyre contains a high proportion of traceable, renewable and recycled materials.

The tyre concept is based on lightweight technology and ensures an extended service life due to renewable tread. The proportion of renewable raw materials used in the Conti GreenConcept is 35%.

The organic materials used include natural rubber from dandelions, silicate from the ashes of rice husks and various vegetable oils and resins, which reduce the amount of crude oil-based materials.

In addition, the Conti GreenConcept is made from 17% recycled materials. As well as processed steel and carbon black, Continental is using polyester from recycled PET bottles in the casing of a tyre for the first time.

Using a lightweight design, developers have significantly reduced the weight and rolling resistance of the concept tyre. All individual improvements together result in lower rolling resistance.

Based on internal analysis, this is around 25% lower than that of a tyre with class A rolling resistance, according to the EU tyre label. Lower rolling resistance means the vehicle consumes less energy, which in the case of electric vehicles, extends range by up to 6%.

The Conti GreenConcept can be replaced multiple times. This improves resource conservation, as renewing tread three times would ensure material used for the casing is halved in relation to its total mileage.

“The cars of the future will still need tyres, which we are making more and more sustainable, as our concept tyre show,” said Continental CEO, Nikolai Setzer.

“The Conti GreenConcept demonstrates how Continental will completely convert its global tyre production to the use of sustainable materials by 2050 at the latest. This underlines our goal of being the most advanced tyre company along the entire value chain by 2030 in terms of social needs as well as our ecological and economic footprint.”

“Step by step, our solutions and technologies are enhancing sustainability and climate protection on the road.”

“From as early as 2022, we will make our global business for emission-free vehicles completely carbon-neutral. By 2040, we are aiming for zero carbon emissions at all of our plants worldwide.

“Finally, by 2050 at the latest, we plan to be carbon-neutral along the entire value chain.
