Warwick Landfill Gas Project

The Warwick Landfill Gas Project is an emissions avoidance project located at the Warwick Waste Management Facility, approximately 10km south-west of the township of Warwick in the Southern Downs region of Queensland. Registered by LGI Limited in February 2025, the project operates within the boundary of the council landfill site. The surrounding region is part of the Darling Downs, a prominent agricultural area heavily utilised for cropping (wheat, sorghum) and livestock grazing.

This project operates under the Carbon Credits (Carbon Farming Initiative, Electricity Generation from Landfill Gas) Methodology Determination 2021. This methodology credits the reduction of greenhouse gas emissions achieved by collecting and combusting methane generated from decomposing waste. While the method title refers to electricity generation, it also encompasses projects that combust gas via flaring to convert potent methane into less harmful carbon dioxide, particularly where gas quality or quantity may not yet support viable power generation.

The Warwick area experiences a warm temperate to subtropical climate with a long-term average rainfall of approximately 600–800mm, which is predominantly summer-dominant. The region is renowned for its fertile soils, particularly Vertosols (black cracking clays) and alluvial soils, which support the district's extensive agricultural output.

A notable feature of this project is its partnership model; LGI Limited collaborated with the Southern Downs Regional Council to install the gas capture infrastructure at no cost to local ratepayers. The system utilizes an LGI250 biogas flare to manage emissions from both legacy and non-legacy waste. Prior to this project, there was no regulatory requirement to capture gas at the facility, ensuring the carbon abatement generated is considered additional and voluntary.
