Integrated Waste Services - LFG Project

Integrated Waste Services - LFG Project is a Landfill Gas project located at Wingfield, approximately 10km north of the Adelaide central business district in South Australia. (Note: While the provided coordinates point to the Integrated Waste Services head office and legacy landfill site in Wingfield, public registry data also associates the project with postcode 5501, which corresponds to the proponent's active Dublin landfill facility). The project was registered in March 2017, and the exact project area is unknown.

Landfill gas projects involve installing a new landfill gas collection system, or upgrading an existing one, to capture methane and other greenhouse gases generated by decomposing organic waste. Standard methodology requirements dictate that the captured gas must be combusted, typically using a flare or a power generator, to convert the potent methane into less harmful carbon dioxide. Proponents are required to continuously monitor and calculate the volume and methane concentration of the gas sent to the combustion device to accurately verify carbon abatement.

The Wingfield and broader Northern Adelaide Plains region is heavily characterised by industrial and commercial land use, encompassing waste recovery, manufacturing, and freight logistics. The regional climate is Mediterranean and classified as semi-arid, experiencing hot, dry summers and moderate winter rainfall (averaging around 500mm annually). The local soils are predominantly reactive coastal clays, sub-coastal estuarine muds, and red-brown earth.

This project was established to install a new collection system to capture and combust gas generated from both legacy and non-legacy waste. It is currently managed by IWS Group Asset Co Pty Ltd, operating as the trustee for the IWS Group Asset Trust. In April 2023, a variation was made to remove Veolia Environmental Services (Australia) Pty Ltd and Acquista Investments Pty Ltd as joint participants, consolidating the project under the IWS Group Asset Trust. Furthermore, the project methodology was updated to Compilation No. 1 of the 2015 Landfill Gas determination in November 2024. The project secured a Carbon Abatement Contract (CAC548746) in April 2017 and completed its obligations in August 2024, having successfully delivered 184,500 ACCUs to the Commonwealth. The proponent, Integrated Waste Services, has a rich local history; it has grown from a single-truck waste removal service founded by Pasquale Borrelli in 1964 into one of South Australia's largest waste management and recycling enterprises.
