Wattle Glen Landfill Gas Project

The Wattle Glen Landfill Gas Project (EOP100560) is a waste sector project located at the Wattle Glen Landfill in Redbank Plains, Queensland. While the coordinates provided in the project data map to Veolia's nearby Ti Tree Bioenergy facility in Willowbank, the Wattle Glen facility itself is situated approximately 20 kilometers east, just over 10 kilometers from the Ipswich CBD and 30 kilometers southwest of Brisbane. The project was registered on February 25, 2014, and is operated by Veolia Environmental Services (Australia) Pty Ltd.

The project operates under the Carbon Credits (Carbon Farming Initiative, Landfill Gas) Methodology Determination 2015. This methodology involves the installation and operation of a system to collect landfill gas, primarily methane generated by the anaerobic decomposition of organic waste, and combust it. By converting methane into carbon dioxide through flaring or electricity generation, the project significantly reduces the global warming potential of the emissions. This specific project is classified as a "transitioning project," meaning it originally started under the earlier Carbon Farming Initiative (CFI) rules before moving to the current Emissions Reduction Fund (ERF) framework. It manages gas from both legacy waste (deposited before the scheme started) and non-legacy waste.

The Ipswich region is characterized by a humid subtropical climate with hot, humid summers and mild winters, typically receiving around 800mm to 900mm of rainfall annually. The Wattle Glen site, historically used for mining before becoming a landfill, sits within an area dominated by industrial land use and remnant bushland. The local geology often consists of sedimentary rocks associated with the Ipswich Coal Measures, resulting in clay-heavy soils that require careful management for drainage and capping in landfill operations.

Notable aspects of this project include its focus on Construction and Demolition (C&D) and Commercial and Industrial (C&I) waste streams. Veolia has managed the site through various rehabilitation phases, including the use of phytocaps (vegetation covers) to manage water balance. The project successfully completed a Carbon Abatement Contract (CAC254087) with the Australian Government in August 2022, delivering its contracted volume of carbon credits.
