Excavated sandstone from Sydney Metro tunnels will be reused to build the new Western Sydney International Airport, as both infrastructure projects begin to take shape.
More than 500,000 tonnes of sandstone will be transported from Metro tunnelling sites to the Western Sydney International Airport site.
Western Sydney Airport Chief Executive Officer Graham Millett said more than 148,000 tonnes of sandstone had already been transported.
“This high-quality sandstone will be used as a high-strength foundation to support the construction of the runway, taxiways and roads on site,” Mr Millett said.
“This is a great example of how we can make the most of Sydney’s infrastructure boom, to not only save taxpayer funds but also cut down on waste.”
Mr Millett said Western Sydney International Airport was committed to sustainability, efficiency, reusing resources and reducing carbon emissions.
“Building the airport is one of the biggest earthmoving challenges in Australian history, but we’ve already moved more than 1 million cubic metres of earth across the 1780-hectare site,” Mr Millett said.
Sydney Metro aims to reuse 100 per cent of the crushed rock produced during the excavation of the 15.5-kilometre twin tunnels between Chatswood and Marrickville.
