  • Can 6PPD be removed from end-of-life tires?
  • We introduce a decontamination strategy that removes 6PPD from end-of-life tires before it enters the broader ecosystem. We demonstrate the catalytic upgrade of 6PPD to safe chemicals and the valorization of crumb rubber to aromatics and carbon black using microwave-assisted pyrolysis.

  • What solvent is used to remove 6PPD from EOL tires?
  • Through batch extraction analysis and computational calculations, acetone is the best suited solvent for 6PPD removal from EOL tires of those tested. Furthermore, the batch extraction kinetics follow a first-order profile.
  • Can a new decontamination strategy be used for recycling end-of-life tire waste?
  • Upcycling end-of-life tire waste is complex due to the recalcitrant nature of the toxic legacy additive, 6PPD. Here the authors present a new decontamination strategy that can isolate 6PPD, convert it to safe and valuable products, and valorize end-of-life tire waste.
  • How does microwave irradiation affect the degradation of a tire particle?
  • The degradation of the tire particle under microwave irradiation was monitored using scanning electron microscopy (SEM) (Fig. 1c, full images, and Supplementary Fig. 5). Initially, the surface of the tire particle was smooth with no substantial defects. After 1 min, the particle surface became rough and non-uniform.
