Casella and Waga Energy launch third RNG facility this year

RUTLAND, Vt., Sept. 03, 2026 /CourierPR/ -- Casella Waste Systems and Waga Energy have inaugurated a new Renewable Natural Gas (RNG) facility at the McKean Landfill in Mount Jewett, Pennsylvania, marking another significant step in their joint effort to convert waste into renewable energy. This marks the third RNG facility to come online this year, following the Chemung County Landfill and the Hyland Landfill projects, completing a partnership agreement signed in 2023.

Ned Coletta, President and CEO of Casella Waste Systems, expressed satisfaction with the facility's launch. "Bringing this facility online at our McKean landfill is another important step in our efforts to recover more value from the materials we manage," Coletta said. "Our partnership with Waga Energy has always been focused on leveraging each other's strengths, and it’s extremely gratifying to see the third facility come online and producing as anticipated."

The McKean facility utilizes Waga Energy's patented WAGABOX® technology to transform landfill gas into pipeline-quality RNG. With 2,000 standard cubic feet per minute (SCFM) of installed processing capacity, the facility can generate up to 407,000 million British thermal units (MMBtu) or 120 gigawatt-hours (GWh) of renewable gas annually. The production will gradually increase as the volume of landfill gas rises.

Guénaël Prince, CEO of Waga Energy Inc., highlighted the successful execution of the project. "The commissioning of the McKean WAGABOX® unit is a strong testament to the commitment and execution capabilities of the Casella and Waga Energy teams," Prince stated. "This project also demonstrates the strength of a partnership model that creates long-term value for both partners by transforming landfill gas into a reliable source of renewable energy."

The RNG produced at the McKean facility will be directly injected into the National Fuel Gas network, providing the region with a renewable alternative to fossil natural gas. The project is estimated to avoid 31,000 tons of carbon dioxide equivalent emissions annually, according to U.S. Environmental Protection Agency standards.

Under the terms of the agreement, Waga Energy fully funded the construction of each facility and will own and operate them for 20 years. Casella and Waga Energy will share the revenue generated from RNG sales.

Casella Waste Systems, headquartered in Rutland, Vermont, offers resource management services to residential, commercial, municipal, institutional, and industrial customers, primarily in the eastern United States. Waga Energy, based in France and operating in several countries, produces Renewable Natural Gas (RNG) by upgrading landfill gas using its patented WAGABOX® technology.

Both companies emphasize the importance of their partnership in transforming waste management into a sustainable energy solution. The McKean facility's launch is seen as a significant milestone in their ongoing efforts to reduce greenhouse gas emissions and promote renewable energy use.
