Researchers at the University of Delaware have developed a promising method to remove toxic particles from end-of-life tyres. A team from the University’s Center for Plastics Innovation and Department of Chemical and Biomolecular Engineering has devised a chemical extraction process to isolate 6PPD from used tyres. The results of this research appear in the publication Nature Chemical Engineering.
To fulfil regulatory requirements in the US state of California, a global group of 30 tyre manufacturers has published a Stage 1 Alternatives Analysis (AA) report concerning the antioxidant 6PPD in tyres. This initial Stage 1 AA Report will serve as the groundwork for further Stage 2 exploration, ultimately culminating in a final AA report.
The U.S. Tire Manufacturers Association (USTMA) is partnering with government agency the United States Geological Survey (USGS) on a research project. The aim of this project is to assess and refine methods of evaluating potential alternatives to 6PPD, the antiozonant widely employed as a rubber stabilising additive when producing tyres.
