Increasing urbanization and development of automobile industry have given rise to an increase in global tyre waste
generation. In Australia, it is estimated that around 450,000 tonnes of tyres reach their end-of-life annually and a large
percentage of it is disposed to landfill or on-site burial or is stockpiled. This poses a significant environmental and safety
risk, since such sites act as a breeding ground for pests and present a significant fire hazard. Hence it is essential to increase
the recycling of this hazardous waste. This paper presents a review of the recycling of end-of-life tyres (EOLT) in Australia
to produce tyre-derived products (TDPs), which traditionally has been based on mechanical recycling methods (using a
series of shredders, screens, and granulators). Key TDPs from Australian tyre recovery include shredded tyres, crumb rubber
and baled tyres. There is currently an emerging market in Australia for chemical recycling of tyres, which are typically
based on pyrolysis and gasification processes. The produced TDPs have a variety of applications, with key most productive
markets being that for crumb rubber in road sprayed seals and rubber granules in soft-fall surfaces and rubber matting in
playgrounds and so on. There is a strong emerging market for rubberized concrete, which can be used as lightweight fill and
as a drainage medium in landfills. New processing technologies like tyre pyrolysis to generate oil and tyre-derived fuel and
also strongly emerging technologies. With a strong push for sustainable design initiatives, TDPs are also being used in
permeable pavements, a water sensitive design strategy that is gaining popularity in Australia.
