  • Does 6PPD ozonation pose environmental risks?
  • 6PPD, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (TP), 6PPD-quinone (6PPDQ), during exposure to gas-phase ozone. Important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of TPs from 6PPD ozonation.
  • 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.

  • Does acetone remove 6PPD from waste rubber?
  • A parity plot of the measured extraction efficiency versus the calculated 6PPD solubility (Fig. 2e) corroborates that solubility is a crucial determinant of the solvent’s ability to remove 6PPD from waste rubber and confirms that acetone is one of the best solvents while being inexpensive and non-toxic.
  • Why is 6ppd-q present in soil?
  • The presence of 6PPD-Q in soil predominantly arises from the deposition of atmospheric particles or dust that carry 6PPD-Q. Soil samples collected from Hongkong's New Territories and Kowloon roadside showed varied concentrations of 6PPD-Q like 9.50–936 ng/g (Cao et al., 2022).
