The Landfill Gas-to-Energy project beneficially utilizes methane, a greenhouse gas naturally occurring from decomposing waste. Methane is collected from a consortium of inactive landfills within Middlesex County - the Edison Landfill, which is owned by Edison Township , ILR, a privately owned landfill, and the Middlesex County Landfill. The gas is then transported via a network of pipelines to the Electric Power Generating Facility in Sayreville , where the gas is converted into 16-megawatts of electrical energy. The recycled energy is used to power the MCUA's operations in Sayreville.

The Landfill Gas-to-Energy project characterizes the future of the waste management industry by introducing sound ingenuity to maximize efficiency in resource management and energy consumption and minimizes the environmental impact of waste disposal. The project is currently producing cost-savings for the MCUA operation and, ultimately, for Middlesex County residents.
