Tumut Landfill Gas Project

Tumut Landfill Gas Project is a landfill gas project located at the Bellettes Landfill in Gilmore, approximately 5km southwest of the township of Tumut in the Snowy Valleys region of New South Wales. Registered on March 22, 2024, the project is managed by LGI Limited in partnership with the landfill operator, Bellettes Bulk Bins. The facility services the local community's waste management needs in an area heavily defined by forestry operations, particularly softwood plantations, and cattle grazing.

The project operates under the Carbon Credits (Carbon Farming Initiative, Landfill Gas) Methodology Determination 2015. This methodology incentivizes the installation of gas collection systems, comprising vertical extraction wells and pipework, to capture methane generated by the anaerobic decomposition of legacy and non-legacy waste. Instead of venting this potent greenhouse gas into the atmosphere, the system channels it to a combustion device (flare). This process converts the methane into carbon dioxide and water, significantly reducing the global warming potential of the emissions.

The Tumut region is characterized by a high-rainfall climate, particularly in winter, and features fertile alluvial and clay soils common to the Snowy Mountains foothills. A notable aspect of this project was its rapid deployment to address significant community concerns regarding hydrogen sulphide (rotten egg) odours in 2023 and 2024. The installation of LGI’s bespoke biogas management system and flare not only generates carbon credits (ACCUs) but also successfully mitigates these local air quality issues.
