NSW road built from soft plastics, glass and recycled asphalt


The first New South Wales road to be built with soft plastics and glass will see plastic from approximately 176,000 plastic bags and packaging and 55,000 glass bottle equivalents diverted from landfill.

Sutherland Shire Council and Downer have partnered with resource recovery and recycling companies Close the Loop, RED Group and Plastic Police to construct the road along Old Princes Highway between Cooper Street and Engadine Road in Sutherland Shire.

Along with soft plastics and glass, toner from approximately 4,000 used printer cartridges and more than 60 tonnes of recycled asphalt were also repurposed to create 220 tonnes of asphalt.

Downer General Manager Pavements, Stuart Billing, said the road product, called Plastiphalt, has a 65 per cent improvement in fatigue life and a superior resistance to deformation making the road last longer, and allowing it to better handle heavy vehicle traffic.

Downer partnered with Close the Loop to tailor waste products such as soft plastics to suit a road construction application.

Sutherland Shire Mayor, Councillor Carmelo Pesce, said Sutherland Shire Council collects over 25 thousand tonnes of recycling in the yellow top bins every year.

“Using recycled plastic and glass in asphalt to create new road surfaces is just one of the innovative ways Council can reduce its environmental footprint through the use of recyclable material.”

The Sutherland Shire Council project is co-funded through the NSW Environment Protection Authority’s Waste Less, Recycle More initiative funded from the waste levy.
