Wagga Landfill Gas Abatement Facility

Wagga Landfill Gas Abatement Facility is a landfill gas capture project located at the Gregadoo Waste Management Centre, approximately 15km south of the Wagga Wagga city centre in the Riverina region of NSW. It was registered in August 2013 and operates over the active footprint of the local landfill area.

Landfill gas projects involve the installation of infrastructure to capture methane gas generated by decomposing organic waste within a landfill. The captured gas is then combusted, often via a flare or generator, which converts the potent methane into carbon dioxide, significantly reducing its overall global warming potential. This particular project captures and combusts gas generated from both legacy and non-legacy waste at the Gregadoo site.

The surrounding Wagga Wagga area is a major agricultural hub characterised by mixed farming, including sheep and cattle grazing, as well as broadacre cropping such as wheat and canola. The region experiences a temperate climate with moderate rainfall, and the soils are typically composed of red earths and clay loams.

An interesting note about this project is that its official proponent shifted from AGL Energy Services Pty Limited to the Wagga Wagga City Council in July 2019. Furthermore, the project secured a Carbon Abatement Contract (CAC216640) with the Commonwealth in April 2015. This contract was successfully completed in May 2022 after the facility delivered its contracted 23,500 Australian Carbon Credit Units (ACCUs) to the government.
