The recycling of rubber from end-of-life tyres (EOLT) has great environmental benefits due to the repurposing of an otherwise waste product, as well as additional benefits due to the improved performance features of many tyre-derived materials. Tyre Stewardship Australia (TSA) acknowledges that any utilisation of recycled tyre material must be done so in a manner that is safe to the community and environment. In Australia in 2020-21, around 459,000 tonnes of used tyres reached their end-of-life. Developing viable, safe and sustainable solutions for EOLT is a priority for TSA. Information and research relating to microplastic pollution, chemical leachate and emissions has recently raised concerns regarding the presence of tyre particles in the community and the environment. The aim of this report was to review, understand, and assess the research regarding the potential health and environmental impacts of tyre particles.
