A cleaner future for tires: Scientists pioneer chemical process to repurpose rubber waste

In the United States alone, over 274 million tires were scrapped in 2021 , with nearly 20% of them being discarded in landfills.

Traditional methods for breaking down rubber focus on devulcanization and cleavage of the polymer backbones using oxidative or catalytic methods.

The researchers introduced a sulfur diimide reagent to enable the installation of amine groups at specific locations in the polymer chains.

This chemical reaction reorganizes the polymer backbone, breaking down the rubber into soluble amine-functionalized materials.

"Our research represents a paradigm shift in how we approach the problem of rubber waste," says Sydney Towell , a co-author of the study.

The method provides a new pathway to transforming post-consumer rubber into high-value materials, reducing reliance on landfills and minimizing environmental harm.
