Landfill Gas Collection at Fairless Landfill

Landfill Gas is produced by the natural decomposition of organic waste in a landfill. Fairless Landfill uses a network of wells to collect landfill gas and control odors. The function of the the landfill's gas wells is complemented by Fairless's capping system. Once installed, landfill capping improves the efficiency of the gas collection system, augments odor-control activities and prevents rain from entering the landfill where it creates wastewater.

With its relatively high energy content, landfill gas represents a low-cost fuel that can be used to power electrical generators. Managing this byproduct as a “green” energy source offers the opportunity to capitalize on an alternative source of electrical power.

With a large and growing number of beneficial-use gas projects around the country, Waste Management is a nationwide leader in turning landfill gas into electrical power. The company has 124 landfill gas to energy related projects operating in 19 states.

Our Current Project:

Since March 2018, Fairless Landfill has been producing and transmitting landfill gas (LFG) to the Exelon Fairless Generating Station. With the recent announcement of Exelon’s plan to shutter the facility in May 2020, WM sought alternative technologies for beneficial reuse of the landfill gas to provide clean efficient energy to the grid. With a renewable energy project taking a few years to develop, the need for an interim stop gap measure to effectively manage landfill gas was identified.  As a stop gap, three (3) ultra-low emission (ULE) flares will be installed to manage the facilities landfill gas until a renewable energy project is brought online.


The Fairless facility has a state-of-the-art 6,250 SCFM compressor station that can convey landfill gas to the Exelon Fairless Generating Station, the Natural Draft Enclosed Flare (currently on site and commissioned in March 2018), as well as the ULE flares and any future WM Renewable Energy Plant. As a proactive measure, a second compressor station will be built and commissioned in 2020 to effectively manage the facility landfill gas.
