Henderson Landfill Gas Upgrade Project

Henderson Landfill Gas Upgrade Project is a landfill gas capture project located at the Henderson Waste Recovery Park, approximately 25km south of the Perth CBD in Western Australia. It was registered in December 2022, and while the exact area footprint is unknown, it is confined to the specific landfill operations site. The region sits within a dedicated industrial zone adjacent to the Australian Marine Complex, and local land use is heavily characterised by heavy industry, shipbuilding, and waste management activities.

Landfill gas projects operate under the Carbon Credits (Carbon Farming Initiative, Landfill Gas) Methodology. These projects involve capturing methane gas, which is generated naturally by decomposing legacy and non-legacy organic waste, and then combusting it. This process converts highly potent methane gas into less potent carbon dioxide, preventing it from freely venting into the atmosphere. To earn carbon credits, the project must achieve net emissions abatement that exceeds historical regulatory baseline levels.

Situated on the Swan Coastal Plain, the environment around the project experiences a Mediterranean climate defined by hot, dry summers and mild, wet winters. The local soils are predominantly sandy, specifically featuring the Spearwood and Bassendean dune systems, which overlay ancient limestone formations. This porous geology typically requires careful management of leachate and underground gas migration for large landfill operations.

This project was set up by the proponent LMS Energy Pty Ltd in partnership with the local council, the City of Cockburn. Project activities focus on upgrading the existing gas collection infrastructure by installing new vertical gas extraction wells and pipework to improve overall methane capture efficiency. Interestingly, the captured methane from this project is not just flared; it is utilized to generate base-load renewable electricity at the on-site Henderson Renewable Energy Facility.
