John Holland paving the way for sustainable road surfaces

In an Australian first, John Holland partnered with Plastic Police to recycle project generated single-use plastics waste into safe and reliable asphalt for local road surfaces.

The landmark collaboration has transformed waste products collected during the construction of the NSW Government’s New Intercity Fleet Maintenance Facility project, into a component of environmentally sustainable asphalt for a local road on the NSW Central Coast.

During construction of the maintenance facility, more than 226 kilograms of soft plastic – equivalent to nearly 57,000 single-use bags – was collected for processing.

Working with Downer, using state-of-the-art technology, the captured soft plastics were processed with other recyclable waste, including used toner cartridges.

The innovative recycling method delivers small pellets, produced by Close The Loop, which are then incorporated within the asphalt mix.

This sustainable initiative reduces the use of crude oil in the construction of local arterial roads and minimises plastic landfill on the NSW Central Coast, helping protect the local wildlife and the marine environment.

Executive General Manager – Infrastructure NSW/ACT, Andrew English, praised the initiative as a demonstration of John Holland’s commitment to innovation and sustainability.

“Today is the first-time an Australian construction project has captured its own production waste and transformed it into an approved road surface” Mr English said.

“Across the world we are witnessing the devastation single-use-plastics wreak on our local bio-diversity and marine life.

“Initiatives such as this demonstrate John Holland’s commitment to delivering sustainable world-class infrastructure, while reducing our environmental footprint.”

John Holland Project Manager, Ivan Karaban, said the project was committed to developing innovative solutions to protect and maintain the local environment.

“Our project team has successfully worked with Australian industry to pioneer this process for the first time on a Transport for NSW site,” Mr Karaban said.

“I am proud we have helped protect the region’s famous natural environment, while delivering this vital transport project for the State.”

John Holland is constructing the maintenance facility at Kangy Angy on behalf of Transport for NSW, to maintain the State’s New Intercity Fleet trains.
