Horsley Park Landfill Gas Project

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

Landfill gas projects under this methodology involve installing or upgrading gas collection systems to capture and combust methane, a highly potent greenhouse gas, generated by decomposing legacy and non-legacy organic waste at landfill sites. The gas is typically destroyed through flaring or used to generate electricity, which earns carbon credits for the emissions avoided.

The Horsley Park area is situated in the Western Sydney basin, a region known for a mix of industrial facilities, waste management centres, and urban fringe parklands. The local climate experiences moderate to high rainfall averaging around 800mm annually, and the environment is characterised by heavy clay soils derived from regional shales.

This project is particularly notable for its innovative waste-to-energy application. Rather than simply flaring the gas, captured methane from the landfill has historically been piped directly to a neighbouring Austral Bricks production facility, where it is used to help power their manufacturing kilns. Originally managed by Veolia Environmental Services, the project underwent a participant name variation, officially transitioning to VELMS Joint Venture Pty Ltd in May 2026.
