Michelin North America Inc. has been developing its tire tread rubber with recycled rubber powder for ten years, and consumers of this product are the brand’s authorized tire retreaders. Currently, the corporation plans to add more of the recycled material into its products consumed by the tire retread industry.

Lehigh Technologies LLC is an important brand for Michelin, as it developed so called “Micronised Rubber Powder” (MRP) which have been purchased by the corporation so its merchandise can become more sustainable.

Currently, Lehigh represents Michelin’s High Technology Materials commercial division, whose team is passionate about recycling absolutely all of its tires – the target is expected to be reached by 2048.

Lehigh has developed a cryogenic rubber recycling system so it can get high technology powder from tires and rubber products – the products are further used in new retread components that can secure greater performance.

According to Michelin, its tires are made of almost 30% of sustainable substances – the prevailing part is bio-sourced materials such as limonele, sunflower oil, natural rubber; and 2% of the content is steel, and the rest comes from recycled tires in a form of rubber powder.

PolyDyne and MicroDyne MRP products that are manufactured by Lehigh are capable of substituting materials that depend on oil and rubber and are used within the industry to make tires, asphalt, plastic and other products.

Michelin’s plan is to become the international dominant company uses recycled tires to produce new tires, thus closing the loop of circular economy. To attain this goal, Michelin has teamed up with Lehigh.

According to Michelin’s representative Gary Scheide, the company is planning to continue recycling tires to produce new tires as this will keep on providing benefits to both buyers and environment.

He also stressed that his company is willing to continue collaboration with Lehigh Technologies, which they consider to be a trustworthy supplier of the products to their North American facilities.

According to Michelin, its plants produce absolutely no waste as they operate in accordance with a closed-loop model, which is fully in line with the cost-effective circular economy.

Michelin and Lehigh are also looking for the ways to expand – the construction of the MRP plant in Spain capable of handling 10,000 metric tons annually is now under way. The facility is expected to be commissioned this summer.
