Michelin Unveils Tire That's Nearly 50 Percent Sustainable

Michelin emphasized its commitment to sustainablility at the Movin’On Summit 2021 (an annual global sustainable mobility summit), where it presented a new racing tire composed of 46 percent sustainable materials. It’s a noteworthy first step in the company’s goal of using 100 percent sustainable materials in its tires—not just for competition, but all tires—by the year 2050. 

The manufacturer chose a racing tire, as opposed to a conventional road tire, to prove it can build a product that’s sustainably made yet also performs without compromise under the intense stresses of motorsports competition. 

How exactly does one go about creating a tirewith 46 percent sustainable materials? Well, you need orange peels and empty beer cans, of course! No, an April Fool’s spoof article this is not; the company also cites lemon rind, pine resin and sunflower oil as other sustainably-sourced or recycled materials in the prototype tire. Most importantly, the recipe calls for more natural rubber (in lieu of synthetic) as well as recycled carbon black (a soot-like carbon particulate commonly used in rubber products) that’s been recovered from worn-out tires. 

Carbon black (pictured) will come from recycled tires in the future.

Michelin has partnered with the GreenGT team to use their Mission H24 hydrogen-powered endurance prototype as a test mule, giving the company access to real-world, on-track R&D. If the company’s engineers can build a sustainable tire that’s good enough for hot-lapping under brutal conditions at the highest speeds, you can probably rest easy about eventually putting a set on your street bike. 

It’s abundantly clear that Michelin is fully committed to a greener business future. In May of this year, we reported their partnership with French biochemistry company Carbios to turn PET plastic waste into reinforcing fibers for its tires; in February, construction began on the company’s first recycling plant; additionally, a target of 40 percent sustainable materials in its tires by 2030 has been set as an interim milestone ahead of its target of 100 percent by 2050. 

Emphasizing its focus on sustainability, Michelin also used the Movin’On Summit to express its plans to reduce the environmental impact of the overall tire production process, including raw materials, road use, and recycling. It also presented the WISAMO project, an inflatable wing sail designed to reduce carbon emissions in maritime shipping. 

2050 may be a long way off, but 2030 is not that far in the future. Do you see Michelin reaching these targets? Are you willing to hit the road on recycled tires?
