'MRA Aggregated Landfill Gas projects

MRA Aggregated Landfill Gas projects is an aggregated landfill gas project located across multiple sites in the Greater Sydney region of New South Wales [1], encompassing postcodes 2047, 2745, and 2765 [2]. It was registered in April 2016 [1]. Because it is a multi-site aggregated project managed by Mike Ritchie and Associates Pty Ltd, a single project area size is not specified.

Landfill gas projects involve installing gas collection systems to capture and combust methane, a highly potent greenhouse gas, generated by decomposing organic waste [1]. Combusting the gas via a flare or using it to generate electricity prevents the methane from entering the atmosphere, resulting in measurable emissions reductions.

The sites are situated in a region known for a mix of urban, residential, and heavy industrial waste land uses. The Greater Sydney area is considered to have moderate to high rainfall, and soils are generally clay and shale-based in the western suburbs (such as those in postcodes 2745 and 2765) and sandstone-derived closer to the inner city.

This project was set up to install a new landfill gas collection system to capture and combust gas from both legacy and non-legacy waste across its aggregated sites [1]. On September 13, 2023, the project underwent a variation to transition to Compilation No. 1 of the 2015 Landfill Gas methodology. Mike Ritchie and Associates (also known as MRA Consulting Group) acts as the primary aggregator, bringing together these municipal and private waste facilities to successfully generate carbon credits.
