BY April, Lake Macquarie council believes it will have reduced the region's carbon emissions by 18,500 tonnes per year - equivalent to removing 2155 cars off the road.
Its green waste project at Awaba Waste Management Facility has been operational for six months and already delivered environmental benefits.
Each day, 100 tonnes of green waste from green-lidded residential garbage bins is delivered on-site and turned into mulch.
The site has been subcontracted to mulching company Remondis, which supplies the mulch to other companies to be sold.
To date, enough green waste to fill 12 Olympic-sized swimming pools has been turned into mulch.
This has extended the life of Lake Macquarie's only landfill rubbish dump from three years to 20 years.
In two years, the council's green waste project will be entering its second phase.
The mulch site will be decommissioned and built into a state-of-the-art green waste management centre that will continue to accept garden cut-offs and integrate organic food scraps.
As the end product will be of higher quality, the mulch will be suitable for residential use.
