Every year, millions of tires end up in landfills, creating an environmental crisis with far-reaching consequences. In the United States alone, over 274 million tires were scrapped in 2021, with nearly 20% of them being discarded in landfills. The accumulation of these waste materials presents not only a space issue but also introduces environmental hazards, such as chemical leaching and spontaneous combustion.

While pyrolysis—a process that chemically recycles rubber through high-temperature decomposition—is widely used, it generates harmful byproducts like benzene and dioxins, posing health and environmental risks.

A study titled “Deconstruction of Rubber via C–H Amination and Aza-Cope Rearrangement,” published in Nature, introduces a novel chemical method for breaking down rubber waste. This technique utilizes C–H amination and a polymer rearrangement strategy to transform discarded rubber into valuable precursors for , offering an innovative and sustainable alternative to traditional recycling methods.

  1. No mention of the tons of toxic micro particulates created as tires wear out. Tires haven’t been made of rubber for many years. Toxic synthetic compouds are used. Thus, the earth is polluted and the inhabitants suffer the consequences.
