Casella Waste Systems and Waga Energy Unveil RNG Facility at Ribbon Cutting
Casella Waste Systems and Waga Energy held a ribbon-cutting ceremony to mark the opening of a renewable natural gas production facility at the Chemung County Landfill in Elmira, New York. The plant has been converting landfill gas into RNG since January 2026 and uses Waga Energy’s patented WAGABOX technology to upgrade the gas to pipeline quality, which is then injected directly into the Valley Energy distribution network.
The facility is designed to generate up to 610,000 MMBtu of renewable gas per year and is expected to avoid more than 47,000 tons of CO2-equivalent emissions annually, according to EPA standards. In its first year, it is projected to produce 340,000 MMBtu, equivalent to roughly 2.4 million gallons of diesel fuel. Casella leaders described the project as a key example of partnering with specialists to create value from waste.
