Casella Waste Systems and Wage Energy open RNG production in New York state
In New York state, Casella Waste Systems, Inc. and Waga Energy held a ribbon-cutting ceremony on May 14, 2026, to celebrate the opening of the RNG production facility at the Chemung County Landfill in Elmira, New York. The facility, which has been successfully turning landfill gas into RNG since January 2026, represents a key milestone in Casella’s efforts to create valuable resources from waste.
The facility leverages the WAGABOX® technology developed and patented by Waga Energy to upgrade landfill gas into pipeline‑quality RNG. The RNG produced on-site is injected directly into the Valley Energy natural gas distribution network, supplying the region with a renewable alternative to fossil natural gas. The facility is designed to generate up to 610,000 MMBtu of renewable gas annually and is expected to avoid more than 47,000 tons of CO₂‑equivalent emissions each year, according to U.S. Environmental Protection Agency (EPA) standards. Through its first four months, the facility has performed well through its ramp up phase, and is projected to produce 340,000 MMBtu in year one which is equivalent to 2.4 million gallons of diesel fuel.
