Bunya Landfill Gas Project

Bunya Landfill Gas Project is a waste emissions avoidance project located at the Bunya Waste Management Facility in Bunya, Queensland, approximately 17km northwest of Brisbane. Registered in April 2014, the project operates within the Moreton Bay Regional Council area. The facility serves as a major waste disposal site for the region, situated in a peri-urban landscape bordered by residential developments and the Bunya State Forest.

The project operates under the Carbon Credits (Carbon Farming Initiative, Electricity Generation from Landfill Gas) Methodology Determination 2021. This methodology involves the installation of gas collection systems, wells and pipes, into the landfill mass to capture methane generated by decomposing organic waste. Instead of venting this potent greenhouse gas into the atmosphere or simply flaring it, the captured gas is combusted in a generator to produce renewable electricity.

The Bunya region experiences a subtropical climate with generally high rainfall, conditions that accelerate waste decomposition and gas production. While the project sits on a man-made landfill structure, the surrounding natural environment is characterized by soils derived from Bunya Phyllite, typically forming deep, gravelly clays.

Operated by LGI Limited in partnership with the Moreton Bay Regional Council, the site has evolved significantly since its inception. Originally transitioning from earlier "CFI" methods, the project upgraded its generation capacity in 2018. Notably, in 2024, it became Queensland's first landfill gas-to-energy project to integrate a utility-scale battery (a Tesla Megapack), creating a renewable hybrid system that allows for the storage and dispatch of electricity to the local grid during peak demand. The project successfully completed its Carbon Abatement Contract (CAC752641) with the Australian Government in May 2022.
