Marsden Park LFG Emission Avoidance Project

Marsden Park LFG Emission Avoidance Project is a landfill gas capture project located at Marsden Park, approximately 50km northwest of the Sydney CBD in New South Wales. It was registered in November 2018. While the exact project area size is not specified on the public register, it is situated in a region of Greater Western Sydney known for rapid urban and residential development, alongside established industrial and waste management facilities.

Landfill gas projects operating under the Carbon Credits (Carbon Farming Initiative-Landfill Gas) Methodology 2015 involve installing a new landfill gas collection system or upgrading an existing one. The standard requirement for this method is to actively capture methane gas generated by decomposing organic waste, both legacy and non-legacy, and combust it through flaring or electricity generation. This process destroys the methane, converting it into carbon dioxide, which has a significantly lower global warming potential.

The Marsden Park area generally experiences moderate to high rainfall, with an annual average of approximately 770mm to 960mm. The local soils are predominantly shale-derived clays, silty sands, and alluvial soils characteristic of the Sydney Basin's Wianamatta Group.

Run by Blacktown Waste Services Pty Limited, this project manages greenhouse gas emissions from a local solid waste landfill using a dedicated gas flare system. Interestingly, as landfill capacities in parts of Greater Sydney begin to reach their operational limits and local councils transition toward alternative resource recovery, the ongoing capture of gas from legacy waste at sites like Marsden Park remains a critical step in achieving regional net-zero emission targets. Operations at the facility are strictly monitored under NSW Environment Protection Authority licenses to manage environmental impacts, including offensive odours and gas flare noise emissions.
