Lithgow Landfill Gas Project

Lithgow Landfill Gas Project is a landfill gas electricity generation project located at the Lithgow Solid Waste Facility, approximately 2km northwest of the Lithgow town centre in the Central Tablelands of New South Wales. Registered in April 2025, the project is operated by LGI Limited, a specialist in biogas recovery and renewable energy generation.

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, such as vertical extraction wells and pipework, to capture methane generated by the anaerobic decomposition of organic waste. Instead of being released into the atmosphere, this methane is combusted in a generator to produce renewable electricity, converting the methane into less potent carbon dioxide and displacing fossil-fuel-based grid energy.

The Lithgow region is characterized by a cool temperate climate with a long-term average annual rainfall of approximately 850mm. The local landscape, positioned on the western edge of the Blue Mountains, features soils primarily derived from Permian sedimentary rocks, including sandstone and shale, typically manifesting as sandy loams or clay loams. While the specific project site is a waste management facility, the surrounding region is historically known for coal mining, power generation, and forestry.

LGI Limited, the proponent, manages a portfolio of similar projects across Queensland and NSW. By capturing gas from both legacy and non-legacy waste at the Lithgow facility, the project not only generates Australian Carbon Credit Units (ACCUs) but also reduces local odour and fire risks associated with fugitive landfill gas emissions.
