  • Can a rubber antioxidant enter the environment with tire-wear particles (Twps)?
  • Recently, it was reported that the rubber antioxidant N - (1,3-dimethylbutyl)- N′ -phenyl- p -phenylenediamine (6PPD or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (TWPs) [7, 8].
  • Are PPD antioxidants effective in reducing tire wear?
  • It is reported that PPD antioxidants have been largely applied in commercial vehicle tire formulations (1–4% by mass). (11,35) Fomba et al. found a larger contribution of tire wear to the atmosphere particulates at a traffic-dominated site (2.0–2.9%) compared to an urban background (1.7–2.1%).
  • Which rubber antioxidants are used in China?
  • Amine antioxidants are the main rubber antioxidants produced and used in China, of which 6PPD and 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ, RD) have the highest production, accounting for more than 80% of the total amine antioxidants.
  • 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.
