City of Canning and Boral paving the way for sustainable roads

12 May 2021
The City of Canning is continuing its commitment to sustainability through its partnership with Boral Australia, in trialling the company's new, more sustainable INNOVO road surfacing mix on Ellam Street in St James.

Boral’s INNOVO product comprises waste tyres, plastic bottles, glass and old road pavement in its road surfacing mix – items which were originally bound for landfill.

The City was the first local government organisation in the country to trial Boral’s sustainable road surfacing product range on Arlington Drive in Willetton in 2019.

Mayor Patrick Hall was on site on Friday 7 May, to watch the works commence and learn more about the product, welcoming the use of more sustainable infrastructure products throughout the City and by other Local Government Authorities.

“Trials of new sustainable products such as the one being used to resurface Ellam Street help to promote the circular economy, and highlight the importance of sustainability to our organisation,” he said.

“I would encourage other local governments to look into using more sustainable products as part of their new build, construction and infrastructure projects - as an increased demand for them will ultimately drive down the cost with economies of scale.”

The materials used in the resurfacing of Ellam Road represent the approximate equivalent of:
  • 37,500 glass beer bottles
  • 58,000 plastic bottles
  • 158 car tyres
  • 15 Tonnes of reclaimed asphalt pavement (RAP) - that would otherwise have gone to landfill.
Processed beyond recognition of their first use, the shredded tyres are turned into small filaments, glass is crushed to the dimension of sand particles, plastic bottles are converted into flakes the size of fish food and asphalt pavements of Perth’s former roads are recycled into aggregates. In addition, the product requires 40% less heat energy in its application.

Boral National Technical Manager Ryan Jansz said the company, which has been Australian-owned and operated for 75 years, was responding to a call by governments and the community for more sustainable business operations and to reuse and recycle wherever possible.

“Materials may shift shape or form as they move between cycles of life, but can retain considerable value as inputs to other products and at the same time, be diverted from landfill or dumping,” Mr Jansz said.

“At Boral, we want to demonstrate, through this trial, that adding recycled materials to modify asphalt, can result in equal or even better performance than those using new or raw materials.”
