The significant growth and development planned for the South District will mean that demand for energy and water and the generation of waste will increase. Without new approaches to the use of energy and water and management of waste, greenhouse gas emissions are likely to increase.
The District has an opportunity to include precinctwide energy, water and waste efficiency systems for land release areas, urban renewal areas, industrial and urban services land, centres and Collaboration Areas. Adopting a place-based approach is necessary to achieve the best sustainability outcomes, including renewing and replacing inefficient infrastructure and organising utilities, waste management, car parking, amenities, open space, urban green cover and public spaces.
Better design of precinct-wide energy, water and waste systems will encourage a circular economy that improves efficiency. A circular economy means designing waste out of the system. For example, a food manufacturing plant could send waste to an adjacent anaerobic digester to power the plant.
Urban renewal projects provide opportunities to improve the energy and water efficiency of new and existing buildings; incorporate building and precinctscale renewables; and manage waste more efficiently to reduce greenhouse gas emissions and costs in a way that appeals to building owners and tenants.
Urban renewal also enables the opportunity to upgrade ageing, water, stormwater, sewer and waste infrastructure at the precinct-scale.
A low-carbon District
More efficient use of energy and water in the District will reduce impacts on the environment and the District's greenhouse gas emissions.
The Greater Sydney Commission has been seeking to better understand greenhouse gas emissions for each District across Greater Sydney and will continue to explore opportunities for planning initiatives to support the NSW Government's goal of achieving a pathway towards net-zero emissions by 2050.
Potential pathways towards net-zero emissions in the District include:
- new public transport infrastructure, electric vehicles and autonomous vehicles to connect residents to their nearest strategic centre or metropolitan centre within 30 minutes
- a range of transport demand management initiatives including working from home, improved walking and cycling, or improved access to car sharing, carpooling and on-demand transport
- new building standards and retrofits so that energy, water and waste systems operate as efficiently as possible in residential and nonresidential buildings
- building and precinct-scale renewable energy generation
- waste diversion from landfill.
The way Greater Sydney's urban structure and built form develop in the future can support NSW's transition towards net-zero emissions. Better integrating land use with transport planning will help slow emissions growth by locating new homes near public transport and high quality walkways and cycle paths.
Building on existing public transport connections with electric vehicle transport hubs, shared autonomous vehicles and other innovative transport technologies can further reduce greenhouse emissions, and reduce levels of noise and air pollution. Prioritising parking spaces for car sharing and carpooling can support more efficient use of road space and help reduce emissions. Emerging transport technologies will reduce the need for parking spaces and help reduce congestion.
Designing high-efficiency buildings and incorporating renewable energy generation will reduce emissions and reduce costs over time. This means improving the energy and water efficiency of buildings, and reducing waste in urban renewal projects and infrastructure projects.
Recycling local water and harvesting stormwater creates opportunities to green public open spaces including parks, ovals and school playgrounds. Recycling water diversifies the sources of water to meet demand for drinking, irrigating open spaces, keeping waterways clean and contributing to Greater Sydney's water quality objectives.
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 are required.
Waste is managed through a number of facilities in the South District. Lucas Heights Resource Recovery Park is the largest waste-receiving facility in the District. Organic waste is diverted through the Garden Organics Processing Facility, producing compost and mulch products for landscaping and horticultural use. The Lucas Heights smart cell facility breaks down organic waste to produce electricity. The Resource Recovery Centre and Waste Collection Point is a separate collection point for recyclable materials, scrap metals, hazardous items, old clothing and household rubble.
There is a waste and recycling centre at Taren Point for recyclable and non-recyclable items. Chullora Resource Recovery Park is a transfer station for general household waste as well as processing garden organics before transfer to other facilities for composting. Some waste disposed in the South District is trucked to landfills outside the District, including interstate.
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 sent to landfill and can help to reduce greenhouse gas emissions.
In higher density neighbourhoods, innovative precinct-based waste collection, re-use and recycling would improve efficiency, reduce truck movements and boost the recycling economy. Where possible, additional land should be identified for waste management, reprocessing, re-use and recycling.
