Waste Assets Management Corporation

Our Waste Assets Management Corporation rehabilitates, remediates and manages legacy contaminated sites and landfills owned by the NSW Government.

We manage and control any potential risks to human health and the environment that these sites pose. We do this while looking for ways to make the best use of the land, so we deliver positive outcomes for the environment and community.

Our highly specialised team of landfill management, monitoring and remediation experts has extensive experience in:

• operations
• engineering
• environmental management
• planning.

Contaminated land management and remediation

The corporation was created under the Waste Recycling and Processing Corporation (Authorised Transaction) Act 2010, which was recently amended to the Waste Assets Management Corporation Act 2023. This allows us to act as the NSW Government’s central agency for managing and remediating contaminated sites.

Legacy landfill sites we manage

We actively manage rehabilitation at several legacy landfill sites and containment cells across NSW, including:

• Eastern Creek
• Castlereagh
• Belrose
• Grange Ave
• Lucas Heights 1 and Harrington’s Quarry
• Merrylands and Thornleigh
• Pasminco site remediation

Our activities on these sites include:

• capping repair
• vegetation programs
• extracting and treating leachate, the contaminated liquid that comes from landfill, so it does not get into the environment or wastewater
• landfill gas containment, extraction and combustion for renewable energy purposes
• the environmental monitoring necessary for each site under the licences that the NSW Environment Protection Authority issues.

Renewable energy

We form temporary partnerships with other businesses in renewable energy. We also offer other specialised environmental services.

We reduce the negative environmental effects of working and closed landfills through initiatives such as:

• efficiently collecting landfill gas
• generating renewable energy
• generating renewable energy certificates.

Our facilities currently generate 87,600 MWh of renewable electricity yearly. They do this while significantly reducing methane gas emissions that affect the climate.

Response plans for potential pollution incidents

We have created management plans for our response to pollution incidents. These are for our sites that hold a current environment protection licence:

• Belrose Pollution Incident Response Management Plan (PDF 615.82KB)
• Castlereagh Pollution Incident Response Management Plan (PDF 629.09KB)
• Eastern Creek Pollution Incident Response Management Plan (PDF 271.95KB)
• Pasminco Pollution Incident Response Management Plan (PDF 710.69KB)

We have created these plans under the Protection of the Environment Operations Act 1997. The plans set out the measures and procedures we follow to prevent or minimise the potential safety and environmental impacts of a pollution incident at each site.
