Western Sydney Waste Diversion Project

The Western Sydney Waste Diversion Project is an Alternative Waste Treatment (AWT) project located in the industrial suburb of Wetherill Park, approximately 30km west of the Sydney CBD in New South Wales. Registered in May 2015, the project operates within a major industrial zone characterized by manufacturing, logistics, and waste management infrastructure. The site is situated near the Prospect Reservoir, a key landmark in the Western Sydney region.

The project operates under the Carbon Farming Initiative's Alternative Waste Treatment methodology. This involves the construction and operation of a facility designed to process mixed solid waste that would otherwise be destined for landfill. By utilizing enclosed composting technology, the project diverts organic material from the waste stream, preventing the anaerobic decomposition that generates methane, a potent greenhouse gas. The methodology requires rigorous monitoring to ensure the waste is effectively processed and that emissions reductions are genuine.

Environmentally, the Western Sydney region falls within the Cumberland Plain, an area known for its temperate climate and average annual rainfall of approximately 800mm to 900mm. The local terrain is generally flat to undulating, with soil profiles dominated by heavy clays and loams derived from Wianamatta Shale. These soil conditions are typical of the Cumberland Lowlands and support the region's dense urban and industrial development.

A notable aspect of this project is its commercial history; it secured a Carbon Abatement Contract (CAC102379) with the Clean Energy Regulator in November 2015. Records indicate that this contract, which originally targeted 125,000 Australian Carbon Credit Units (ACCUs), was marked as completed in September 2023. The project stands as an example of private sector investment by Corporate Carbon Solutions in waste diversion infrastructure to generate carbon credits.
