In conjunction with Hunter Water, Edge Environment and Sustainability Advantage, our low carbon road project is exploring different materials we may be able to use in our roads.
From a carbon, water intensity and ecotoxicity perspective, glass, tyres, fly ash, toner, plastic and recycled concrete may be possible solutions.
Our decision-making tool, co-funded by Hunter Water and the NSW Government, sheds better light on the impacts of materials used when building new roads.
