Gympie Landfill Gas Project

Gympie Landfill Gas Project is a landfill gas capture project located at the Bonnick Road Waste Management Facility, approximately 6km southwest of Gympie in Queensland. It was registered in November 2017, and while the exact project area size is not publicly specified, it operates within the boundaries of the municipal landfill footprint.

Landfill gas projects involve the installation of a new gas collection system, or the upgrade of an existing one, to extract and capture biogas, primarily methane, generated by decomposing legacy and non-legacy waste. The standard requirements for this methodology dictate that the captured methane must be combusted, often through an enclosed flare or power generator, to convert it to less potent carbon dioxide. Projects are required to continuously monitor and measure the volume and methane concentration of the gas sent to the combustion device to accurately calculate emissions abatement.

The Gympie region is known for its diverse agricultural operations, including dairy and beef cattle grazing, horticulture (such as macadamias), and pine forestry plantations. The area experiences a subtropical climate with relatively high annual rainfall (averaging around 1,100mm). The local soils range from fertile alluvial plains along the nearby Mary River to podzolic and clay loam soils in the surrounding hills.

This project was established by the proponent, LGI Limited, in partnership with the Gympie Regional Council. An LGI-designed 500 biogas enclosed flaring unit was initially installed and was later upgraded to a 1000 unit in 2026 to manage the landfill's emissions. By early 2023, the collaboration had successfully abated 90,000 tonnes of CO2 emissions. This environmental milestone is equivalent to removing 5,000 cars from the road for a year or planting 1.5 million seedlings over a decade.
