Building waste being reboarded on roads

The Waste Authority’s pilot Roads to Reuse project has been a success and will now be expanded, using demolition material from the former Princess Margaret Hospital site.

The project uses recycled construction and demolition (C&D) material as road base.

In a statement, the Authority said the Roads to Reuse pilot had used more than 25,000 tonnes of recycled C&D material as part of the Kwinana Freeway Northbound Widening Project from Russell Road to Roe Highway.

A further 7,000 tonnes of material was used in the Murdoch Drive Connection project.

Minister for Environment, Amber-Jade Sanderson said six buildings had been demolished on the hospital site with six to go.

“It is estimated more than 80,000 tonnes of non-hazardous material will be recycled from the site,” Ms Sanderson said.

“Construction and demolition waste makes up about half of WA’s waste stream and represents about half of material recovered for recycling.”

Ms Sanderson said the Waste Authority was working hard to increase the recovery of C&D to meet the State’s target to recover 75 per cent of materials by 2030.

Roads to Reuse is an exciting example of how collaboration across industry and Government can foster a circular economy that provides cost savings and benefits while protecting the environment,” she said.

“Since 2019, 62,000 tonnes of Roads to Reuse materials have been used in Western Australian roads.”
