TSA accreditation gains momentum with local governments

An additional six local government authorities have received Tyre Stewardship Australia (TSA) accreditation after using tyre-derived raw materials in infrastructure projects.

TSA confirms that the six new government authorities to receive accreditation are: Burdekin Shire Council (QLD), Campbelltown City Council (SA), Launceston Shire Council (TAS), Paroo Shire Council (QLD), Prospect City Council (SA) and Upper Hunter Shire (NSW).

TSA CEO, Lina Goodman, said having local authorities on board was a vital step towards ensuring the sustainable management of old tyres – noting that having more councils on board would help drive the commercial viability of developing new and improved tyre-derived products.

“Along with transport companies, local governments deploy significant fleets of vehicles,” said Goodman.

“Ensuring that the tyre needs of those fleets are catered for only by entities committed to responsible end-of-life tyre management can make a significant impact on sustainable outcomes for the over 56 million end-of-life tyres Australia generates every year.”

All newly TSA-accredited councils will be closely watching crumbed-rubber asphalt trials in South Australia’s City of Mitcham, with a view off specifying the use of similar surfaces for their future road maintenance and enhancement projects, according to Goodman.

“Crumbed-rubber asphalt has been in extensive use overseas, in climatic conditions similar to Australia, with long term use in California, Arizona and South Africa delivering excellent road performance results and highly desirable sustainability outcomes,” said Goodman. “The local road trial will be looking at a range of performance factors, such as cracking, rutting, moisture retention and general durability.”

Goodman said all local authorities have the opportunity to use recycled tyre-derived materials in urban infrastructure, through both well-established applications and rapidly emerging new products.

“Existing uses of tyre derived material, for applications such as providing soft fall surfaces on playgrounds, are being added to by innovations such as erosion protection wall systems in waterways, noise barriers along roads and permeable pavements for carparks, footpaths and walking tracks,” she said. “A major focus for the development of new materials is the continual improvement and tailoring of crumbed-rubber asphalt used in roads.”
