Casella Waste Systems, Inc. and Waga Energy Sign Agreement to Develop Renewable Natural Gas Capacity at Select Landfills

RUTLAND, Vt.-- Casella Waste Systems, Inc. (Nasdaq: CWST), a regional solid waste, recycling, and resource management services company, and Waga Energy (EPA: WAGA), a global expert in the production of renewable natural gas (“RNG”) from landfills, announced the signing of a commercial agreement on July 10, 2023 to develop renewable natural gas facilities at three Casella landfills. As part of the commercial agreement, Waga Energy will deploy the capital required to fully fund construction of the projects and will own and operate the RNG infrastructure. Casella and Waga Energy will share in the revenue generated from the RNG facilities once operational.

Commercial operations are expected to start in approximately 24 months given the timeline for permitting and construction. The initial production across these three sites is expected to total approximately 1,300,000 MMBtu per year of RNG. Casella will receive from Waga Energy a royalty stream to supply landfill gas to the RNG facilities and the projects may be entitled to investment tax credits as part of the Inflation Reduction Act.

Casella, Chairman and CEO of Casella Waste Systems, Inc. “We have been impressed by Waga Energy’s innovation and technology platform and believe that they are a strong partner to help develop RNG capacity at these three facilities.”
