Cessnock Landfill Gas Project

The Cessnock Landfill Gas Project is a waste sector project located at the Cessnock Waste Management Centre, approximately 5km east of the Cessnock town centre in the Hunter Valley region of New South Wales. Registered in December 2013, the project is operated by LMS Energy Pty Ltd, a prominent company in the Australian bioenergy sector. The project area sits within a region traditionally known for a mix of land uses, including coal mining, viticulture, and grazing, although the specific site is a dedicated waste management facility established on a former mining and quarrying lot.

This project operates under the Carbon Credits (Carbon Farming Initiative, Landfill Gas) Methodology Determination 2015. Landfill gas projects involve the installation of a network of wells and pipes to extract methane generated by the decomposition of organic waste. This captured gas is then combusted using a flare or an electricity generation unit, converting the potent methane into carbon dioxide, which has a significantly lower global warming potential. As a transitioning project, it was originally established under the earlier Carbon Farming Initiative (CFI) before moving to the Emissions Reduction Fund (ERF) framework, capturing gas from both legacy (pre-2012) and non-legacy waste.

The environmental conditions of the Cessnock region are characterized by a warm temperate climate with a mean annual rainfall of approximately 750mm. The soils in the broader Hunter Valley area are diverse, often consisting of texture-contrast soils such as Chromosols (red-brown earths) and Sodosols (duplex soils) with clay subsoils, though the project site itself sits on highly disturbed ground due to its history as a mine and active landfill. Recent local developments include a significant expansion of the landfill facility to extend its operational life by another 20 years, ensuring continued feedstock for gas capture activities.
