Used glass will be given new life in the Sutherland, St George and Bayside council areas.
The three neighbouring councils have pledged to end glass waste by using recycled glass as a substitute for natural sand in local roads and footpaths.
The three councils have joined a new sustainable road-making initiative by Southern Sydney Regional Organisation of Councils (SSROC) called, Procure Recycled: Paving the Way.
The project is expected to increase traditional road-making transport efficiency by using locally recycled glass instead of sand from distant quarries.
It will save 414 tonnes of CO2 emissions per year in these three LGAs alone, which is equal to planting 7000 trees a year.
Georges River Council mayor Kevin Greene said the council was 'extremely proud to be a part of this gamechanging and cost-effective partnership'.
"Our community already plays a pivotal role by recycling correctly, so using those materials and acting together will show our determination to reduce our impact on the environment," he said.
"The commitment means we are one step closer to our long-term goal of zero waste to landfill and our bold target to achieve net zero emissions by 2025."
More than 4000 tonnes of crushed glass, or up to 18.4 million bottles from yellow-lidded bins, will be used to build local roads each year.
Bayside Council mayor Joe Awada said the 'extraordinary' initiative would form a part of the council's waste management strategy.
"Bayside Council was one of the first councils in the country to trial the use of recycled material, which included crushed glass, plastic bags and toner catridges, in creating a 400 tonne dual road carriageway at the Bexley depot for our Community Recycling Drop Off Events in 2019," he said.
"Off the success of that trial, Bayside committed to using recycled content in all future road resheeting programs to produce outstanding outcomes similar to Bayside's 2020/21 annual road re-sheeting program, resulting in renewing 36 local roads using 4455 tonnes of recycled asphalt and 570 tonnes of crushed recycled glass equivalent to over 2.6 million glass bottles.
"I am proud that this joint Paving the Way initiative will expand upon the great results achieved by such innovative trials."
Sutherland Shire Council mayor Steve Simpson said the sustainable road construction initiative followed similar successful trials in the shire which had focused on incorporating recycled materials into road paving.
"We know our community feels strongly about the need to preserve our stunning local environment, and that's why Sutherland Shire Council continues to seek out opportunities to incorporate recycled materials into our road construction projects," he said.
"We are keen to find new ways to deliver hard wearing, long lasting roads infrastructure that our community relies upon in an environmentally sustainable way, and this trial sees us further explore ways in which this can be achieved."
Sixteen Sydney councils have now joined the Paving the Way initiative, making it the largest local-government-led procurement of its kind in NSW history.
Councils participating in Paving the Way include Bayside, Burwood, Canada Bay, Canterbury-Bankstown, City of Sydney, Georges River, Hornsby, Inner West, Lane Cove, Northern Beaches, Randwick, Ryde, Sutherland, Waverley, Willoughby and Woollahra.
