Hawkesbury Landfill Gas Upgrade Project

Hawkesbury Landfill Gas Upgrade Project is a landfill gas capture and combustion project located at a waste management facility in South Windsor, approximately 50km northwest of Sydney in New South Wales. It was registered on March 27, 2022. The specific project area size is unlisted as the activities take place over an active operational landfill cell.

Landfill gas projects operating under the 2015 methodology involve installing or upgrading systems to capture biogas (primarily methane) generated from decomposing legacy and non-legacy organic waste. The captured gas is then permanently combusted using flares or converted into dispatchable renewable electricity, which significantly reduces the facility's greenhouse gas emissions.

The surrounding Hawkesbury region sits within the broader Sydney basin, an area known for a mix of peri-urban development, grazing, and agricultural land uses such as turf farming and market gardens. The local environment experiences moderate to high rainfall and features a range of soil types, predominantly Chromosols, Tenosols, and Dermosols formed from alluvial plains and Hawkesbury sandstone.

An interesting note about this project is that it is managed by LGI Limited, an ASX-listed clean energy company that frequently partners with local governments across Australia. LGI upgraded the existing landfill gas collection system at the Hawkesbury City Waste Management Facility to maximize the capture of methane, successfully turning a council liability into a carbon abatement asset.
