A frame made of soybean oil and rice husks? A real revolution awaits the automotive industry

During this year’s CES Consumer Electronics Show in Las Vegas, the premiere of the Goodyear environmental tire took place. The novelty features a revolutionary design in which up to 17 components in 12 are made from renewable materials.

The product itself also has lower rolling resistance compared to a tire made of conventional materials, which means less fuel consumption while driving.

An environmental tire is made up of four types of soot, which are produced from methane, carbon dioxide, vegetable oils, and oils from the pyrolysis of expired tires. This sustainably produced component is designed to strengthen the compound and increase tread durability.

The residue also includes soybean oil, which helps maintain the elasticity of the tire’s rubber compound in varying temperatures, and a unique type of silica made from rice husk ash, which improves grip and reduces fuel consumption.

The composition of the tires also includes polyester obtained from the recycling of plastic bottles and other plastic waste, which can be used in tire ropes, bio-renewable resins from pine trees that replace petroleum resins, and are used to increase the traction properties of the tire, as well as granules for wire and steel ropes made Made of steel with a high percentage of recycled raw materials, which strengthens the radial frame structure.

Frame width made at 90 percent. Sustainable materials come just a year after Goodyear introduced a similar solution made from 70% renewable materials. The brand already uses sustainable materials in the production of select tire lines. Soybean oil can now be found in eight product lines as well as some racing tyres.

Other tire manufacturers are striving to reduce their carbon footprint.

Nokian and Michelin have already announced their work on tires made from renewable, recycled, bio-sourced or other sustainable materials.

Among the solutions that can replace classic tires in the future, airless tires are mentioned, which will be more comfortable and difficult to damage.

Its design will reduce the use of raw materials and the amount of waste associated with the production of new tyres, which will be used to replace punctured, damaged or very quickly worn tires.
