At the end of their single use
lifetime, what do we do with the billions of tires made each
Tires are mostly burned, pyrolyzed into carbon black, methane, oil and other products, or simply ground up and used in relatively low value applications.
We have found a way to break the sulfur-sulfur bonds (the 'vulcanization') used to hold the rubber together.
Our current research is focused on:
