Plastic bags, recycled glass and printer toner will be used in the construction of new Hunter roads as part of a $5 million overhaul of Downer’s asphalt plant in Teralba, Lake Macquarie.
Lake Macquarie Mayor Kay Fraser officially opened the site this week, with the ability to process thousands of tonnes each year of sustainable road and pavement materials for the Hunter Region and Central Coast.
The facility is one of the most advanced of its kind in Australia, capable of producing a wide range of products including asphalt containing recycled tyre rubber and Reconophalt, an innovative asphalt product that contains high recycled content from materials such as soft plastics, glass, toner and reclaimed road.
The soft plastics are collected through the RedCycle program, which has collection bins in Coles and Woolworths supermarkets, while waste toner used in the product comes from the national Planet Ark recycling initiative.
Every kilometre of two-lane road made with Reconophalt contains the equivalent of 530,000 plastic bags, 168,000 glass bottles and 12,500 toner cartridges.
Cr Fraser said today’s opening, which coincides with World Environment Day, bolstered Lake Macquarie’s reputation for encouraging and embracing sustainable businesses and practices.
“I congratulate Downer on investing in new methods to close the loop on recycled materials,” Cr Fraser said.
“In the past 12 months in Lake Mac, we’ve seen the introduction of recycled glass sand in Council’s civil works, a trial of recycled materials in concrete footpaths and now this next step in our war on waste.”
Downer’s Executive General Manager Road Services, Dante Cremasco, said the milestone event held on World Environment Day demonstrates the importance of partnerships with councils and road authorities to maximise sustainable outcomes for the future growth of the region.
“The innovation our new Teralba asphalt plant brings will see us not only lower our carbon footprint, but also incorporate new streams of recycled materials into the asphalt we lay, further improving sustainable outcomes for the region’s local communities and their roads,” Mr Cremasco said.
“Downer’s investment in this flexible pavement products manufacturing hub allows us to reduce our reliance on increasingly scarce virgin materials by over 30 per cent and improve our energy consumption by up to 15 per cent, which are really pleasing outcomes for the region.”
Testing of the new Reconophalt material showed it lasted longer and was less prone to deformation than traditional forms of asphalt.
