Recycling and reducing waste
There is diminishing capacity in existing landfill sites in Greater Sydney, with more waste being sent to landfill outside the region. This increases costs to the community. Additional sites for waste management in Greater Sydney would improve efficiencies in managing waste.
The planning and design of new developments should support the sustainable and effective collection and management of waste. The Environment Protection Authority has prepared a range of guidelines and other information to assist in the sustainable management of waste.
Treating separated organic waste and then processing it through an energy-from-waste facility will reduce waste to landfill, and help to reduce greenhouse gas emissions.
Blacktown, Parramatta and Cumberland councils use alternative waste treatment facilities to capture and recover more recyclable materials from the redlid general waste bins. This process helps to increase the recycling rate.
In higher density neighbourhoods, innovative precinct-based waste collection, re-use and recycling would improve efficiency, reduce truck movements and boost the recycling economy. This approach could be initially established in the District’s larger centres, such as Greater Parramatta, Blacktown, Sydney Olympic Park and Norwest. Where possible, additional land should be identified for waste management, reprocessing, re-use and recycling.
By 2050, GPOP residents will consume more than 40 gigalitres of water each year. To address this, non-drinking water will be used for toilet flushing, irrigation of green spaces and other appropriate uses in homes.
GPOP presents the opportunity to change the way that water resources are managed. This will shift from reliance on coastal treatment and ocean discharge of treated wastewater and will plan a new facility on a site up to 17 hectares in GPOP’s urban services area.
Collaboration and strategic partnerships can develop a hub where this valuable resource is managed and recycled locally. This facility would become an innovative and integrated resource recovery facility which, would produce recycled water; co-digest domestic biosolids and food waste to generate energy; and potentially be a net electricity exporter to the grid.
Exploring opportunities to leverage the Olympic legacy of the ‘Green Games’ and the Sydney Olympic Park Authority Act 2001 that encourages the use of renewable energy with the goal of developing and attracting clean and green industries.
Precinct-scale approaches have also been adopted in the Rouse Hill Town Centre, which is a low-water, low-energy and renewable energy-based precinct. These principles could be extended to other growth areas and urban renewal projects.
