Downer EDI Works designs, builds and sustains assets, infrastructure and facilities and are a leading provider of integrated services in Australia and New Zealand.
Downer’s road surfacing business has been creating and delivering solutions for customers in South Australia for more than 50 years, and they have managed and maintained state road networks and assets for the last 22 years. In partnership with the City of Adelaide and other local government bodies, Downer seeks to apply sustainable asphalt solutions as a contribution to reducing the carbon emissions embodied in our roads.
In 2013–2014, Downer invested in the future-focused construction and commissioning of a technologically-advanced asphalt plant in South Australia at their flexible pavement products manufacturing hub in Wingfield. The plant is one of the latest High Recycling Technology (HRT) Series mixing plants, capable of producing a wide range of sustainable asphalt products.
Downer’s recycled asphalt products include crushed glass, soft plastics, crumb rubber, recycled asphalt pavement, and recycled cooking oils, products that come from streams previously destined for landfill, removing the requirement for virgin materials which are sourced through environmentally destructive methods. The process they use also reduces carbon emissions significantly through lower mixing temperatures (warm mix asphalt).
Furthermore, Downer Group has announced a carbon-neutral target date of 2050, reconfirming the organisation’s commitment to and momentum toward 100% sustainable operations.
