Casella Waste Systems (CWST) and Waga Energy (WAGA) have started operations at a new Renewable Natural Gas production facility at the McKean Landfill in Mount Jewett, Pennsylvania. This is the third RNG facility brought online in 2026 under their 2023 partnership, following Chemung County and Hyland landfills.
The McKean facility uses Waga Energy’s patented WAGABOX® technology to upgrade landfill gas into pipeline-quality RNG. With 2,000 SCFM of installed processing capacity, it can generate up to 407,000 MMBtu (120 GWh) of renewable gas annually, with output expected to ramp as landfill gas volumes increase.
The RNG is injected directly into the National Fuel Gas network, providing a renewable alternative to fossil natural gas and is expected to avoid 31,000 tons of CO₂-equivalent emissions per year. Waga Energy fully funded and will own and operate all three facilities for 20 years, while Casella and Waga share revenue from RNG sales.
Casella Waste Systems (Nasdaq: CWST) reported Q2 2026 revenues of $543.7 million, up $78.4 million or 16.9% year over year, driven by acquisitions, higher collection and disposal pricing, increased landfill volumes, and growth in Resource Solutions National Accounts. Solid waste pricing rose 5.5%, including 5.8% collection and 4.7% disposal price growth.
Operating income was $20.0 million, up 3.6%. Net income fell to $3.8 million from $5.2 million, mainly due to higher depreciation and interest expense, while Adjusted Net Income increased 4.6% to $25.3 million and Adjusted EBITDA grew 12.5% to $123.2 million. Year-to-date, net cash from operating activities rose 15.3% to $161.0 million and Adjusted Free Cash Flow increased 10.3% to $78.1 million. The company has closed five acquisitions in 2026 with approximately $165 million in annualized revenues, raised 2026 revenue guidance to $2.090–$2.110 billion, and lowered net income guidance to $0–$6 million while reaffirming Adjusted EBITDA, operating cash flow, and free cash flow outlooks.
