Horsley Park Landfill Gas Project

Horsley Park Landfill Gas Project is a landfill gas project located at Horsley Park, approximately 40km west of the Sydney CBD in New South Wales. It was registered in December 2012 and covers an unknown area.

Landfill gas projects involve the installation of infrastructure to capture methane gas emitted by the decomposition of organic waste at landfill sites. The captured gas is then combusted, usually via a flare or an engine to generate electricity, which converts the potent methane into less harmful carbon dioxide and reduces overall greenhouse gas emissions.

The Horsley Park area has historically featured rural-residential acreage and agricultural market gardens, but regional land use is increasingly dominated by industrial development, logistics, and resource recovery facilities. The region experiences moderate rainfall, averaging roughly 757mm annually, while local soils are typically heavy, shale-derived clays that hold water heavily after rain and are prone to cracking during dry spells.

This transitioning project originally operated under a revoked 'CFI' method and continues to capture and combust gas generated from both legacy and non-legacy waste at the landfill facility. Over its lifespan, the project methodology has been updated several times, most recently in 2022 to the Carbon Credits (Carbon Farming Initiative-Landfill Gas) Methodology Determination 2015 (Compilation No. 1). The project was contracted for carbon abatement in April 2015, and its associated contract (CAC254087) was successfully completed in November 2022. Furthermore, in May 2026, the official project proponent was varied from Veolia Environmental Services (Australia) Pty Ltd to VELMS JOINT VENTURE PTY LTD, reflecting an ongoing joint venture arrangement in the project's operation.
