Casella Waste Systems and Waga Energy Bring Third RNG Facility Online at McKean Landfill
RUTLAND, Vt., September 3, 2026 - Casella Waste Systems, Inc. (Nasdaq: CWST), a regional solid waste, recycling and
resource management services company in the Eastern United States, and Waga Energy (EPA: WAGA), a global expert in the
production of Renewable Natural Gas ("RNG") from landfills, announced the start of operations of the RNG production
facility at the McKean Landfill in Mount Jewett, Pennsylvania.
The McKean facility is the third to come online this year, following the successful commissioning of facilities at the
Chemung County Landfill and the Hyland Landfill. Together, the three projects complete the partnership agreement signed
in 2023.
"Bringing this facility online at our McKean Landfill is another important step in our efforts to recover more value
from the materials we manage," said Ned Coletta, President and CEO of Casella Waste Systems, Inc. "Our partnership with
Waga Energy has always been focused on leveraging each other's strengths to drive economic and environmental benefits,
and it's extremely gratifying to see the third facility come online and producing as anticipated."
The facility uses Waga Energy's patented WAGABOX technology to upgrade landfill gas into pipeline-quality RNG. With
2,000 SCFM (3,200 m3/h) of installed processing capacity, McKean can generate up to 407,000 MMBtu (120 GWh) of
renewable gas annually. Production will ramp up progressively as landfill gas volumes increase at the site.
"The commissioning of the McKean WAGABOX unit is a strong testament to the commitment and execution capabilities of
the Casella and Waga Energy teams," said Guénaël Prince, Chief Executive Officer of Waga Energy Inc. "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 on-site is injected directly into the National Fuel Gas network, supplying the region with a renewable
alternative to fossil natural gas. The project is expected to avoid 31,000 tons of CO2-equivalent emissions each year,
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
each of them for 20 years, while Casella and Waga Energy share the revenue generated from RNG sales.
