Tyre Stewardship Australia was formed to implement the national Tyre Product Stewardship Scheme to promote the development of viable markets for end-of-life tyres.
To minimise the environmental, health and safety impacts of end-of-life tyres, Australia needs diverse and sustainable markets for tyre-derived product (TDP). Stronger markets for TDP will mean more tyres get recycled rather than mishandled and stockpiled creating risk for the community. Stronger markets act to reduce this risk by creating more value for waste tyres and driving more competition for material. This supports a more robust recycling market that feeds a stronger and more diverse TDP consuming manufacturing sector.
There is a wide range of current and new tyre-derived products in the marketplace. Below are some case study examples of existing and new materials that have been developed.
The City of Mitcham, in South Australia, is the latest local government authority to work with TSA on testing new mixes of crumbed rubber asphalt that can improve road durability and offer a significant recycling use for the millions of used tyres Australia generates each year.
TSA accredited recycler, Lomwest Enterprises of Western Australia, has created a multi- application, high-performance wall system using baled end-of-life tyres sandwiched between highly stable concrete skins.
The casual observer could be forgiven for thinking that the only likely use of recycled tyre products in sporting venues could be in the synthetic athletic tracks. The reality is that all that appears to be just grass or sand, may well not be.
Geelong based joint high-tech manufacturing companies, Polymeric Powders and Austeng, are using end-of-life tyre crumb combined with polyolefin plastic to manufacture a superior quality composite material, enabling the production of commercial pipes using an Australian developed ‘world’s first’ process.
The commercialisation of innovative technologies could, in the near future, see trucks running on tyres that will subsequently find a second life not only in the road surface but also in the fuel powering the rig.
Retaining walls have been around since the most ancient of civilisations and the engineering challenge of turning sloping sites into multiple flat levels has seen the same basic principles applied since those times.
