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 the Gympie town centre in Queensland. Registered in November 2017, the project operates within the Gympie Regional Council area, a region characterised by a mix of grazing, forestry, and rural residential land uses.

Landfill gas projects involve the installation of gas collection systems, comprising wells and pipework, into landfill waste masses to capture methane generated by decomposing organic matter. Under the Carbon Credits (Carbon Farming Initiative-Landfill Gas) Methodology Determination 2015, this captured gas is combusted, typically via a flare or an electricity generator. This process converts methane, a potent greenhouse gas, into carbon dioxide, which has a significantly lower global warming potential. The project generates Australian Carbon Credit Units (ACCUs) for the net reduction in emissions.

The Gympie region experiences a subtropical climate with relatively high rainfall, averaging around 1,100mm annually. The surrounding landscape features diverse soil types, including kurosols (texture-contrast soils) and podzolics, often supporting the region's strong beef and dairy grazing industries.

A notable aspect of this project is its voluntary nature; the site had no regulatory requirement to capture biogas, meaning the carbon credit revenue was the primary driver for making the infrastructure commercially viable. The project proponent, LGI Limited, installed a bespoke "LGI 500" biogas flare at the site. Corporate reports indicate that since its inception, the project has abated over 90,000 tonnes of CO2-e, which the proponent equates to removing approximately 5,000 cars from the road.
