The automotive industry has been recycling tires for nigh onto 100 years, originally motivated by the high cost of buying rubber. It’s a process not without controversy: Many castoffs ultimately are burned after the most valuable materials have been scrapped. On the other side, many argue that’s a better option than burying tires in landfills.
But the conversation detoured into new territory in late 2017. That’s when French tire giant Michelin acquired Lehigh Technologies, a 15-year-old company that reincarnates end-of-life tires into a specialty material called micronized rubber powder (MRP). The substance is already used by more than 60 companies (among them are seven of the world’s 10 biggest tire makers) for a wide range of applications, including as a feedstock for the sorts of high-performance tires Michelin sells. It is sold to more than 42 plants in 15 countries.
