Integrated Waste Services - LFG Project

Integrated Waste Services - LFG Project is a landfill gas capture project located in Wingfield, approximately 10km northwest of the Adelaide CBD in South Australia. It was registered in March 2017. While the exact project area is not publicly specified, it operates across the active footprint of the Integrated Waste Services Wingfield waste management and recycling facility.

The Wingfield area serves as a primary industrial and waste management hub for the broader Adelaide region, situated near coastal wetlands. The local environment features a Mediterranean climate characterized by moderate to low winter-dominant rainfall. The local soils consist predominantly of heavy coastal clays and loams; these clay soils are highly beneficial for landfill operations as they provide a naturally impermeable barrier that helps contain leachate and protect the underlying groundwater.

Landfill gas projects involve the installation of a gas collection system within a landfill to capture methane produced by decomposing organic material. Under the Carbon Credits (Carbon Farming Initiative-Landfill Gas) Methodology, the standard requirement is to continuously measure the methane sent to a combustion device (such as a flare or generator) where it is safely destroyed. Capturing and destroying methane, a greenhouse gas 28 times more potent than carbon dioxide, prevents it from entering the atmosphere. This specific project installed a new collection system to capture and combust gas generated from both legacy (historical) and non-legacy (new) waste at the site.

This project has reached several administrative and commercial milestones over its lifetime. It was initially operated in partnership with Veolia Environmental Services, but underwent a proponent variation in April 2023, transferring sole custodianship to the IWS Group Asset Trust. The project was also backed by an early Emissions Reduction Fund contract (CAC548746) secured in April 2017, which was successfully completed as of August 2024. Most recently, the project's methodology was updated to Compilation No. 1 in November 2024.
