Waga Energy and Casella Will Produce RNG at Three Landfills in the US

Waga Energy signed a commercial agreement with Casella Waste Systems, Inc. to build and operate three Renewable Natural Gas (RNG) production units at landfills in the United States. This new contract, involving the initial deployment of approximately 1,300,000 MMBtu (380 GWh) of production capacity, marks a major step in the development of RNG in the United States, supporting the energy transition.

EYBENS, FRANCE / ACCESSWIRE / July 10, 2023 / Waga Energy (EPA:WAGA), a global expert in the production of renewable natural gas (RNG) from landfills, and Casella Waste Systems, Inc. (Nasdaq:CWST), a regional solid waste, recycling and resource management services company in the United States, announced the signing of a commercial agreement on July 10, 2023 to develop RNG projects at three Casella landfills.

As part of the commercial agreement, Waga Energy will deploy the capital required to fully fund construction of three RNG units, using its patented WAGABOX^® technology, and will own and operate them for 20 years. Casella and Waga Energy will share the revenue generated from the RNG units once operational. Commercial operations are expected to start in approximately 24 months given the timeline for permitting and construction.

The three WAGABOX^® will initially produce approximately 1,300,000 MMBtu (380 GWh) of RNG per year, and save 90,000 tons of eqCO2 emissions per the United States Environmental Protection Agency (EPA).¹ RNG, a key pilar for the energy transition, is a local, renewable and competitive energy that can substitute fossil-based fuels in transportation, industry and heating.

The results of 15 years of development, the WAGABOX^® technology maximizes the energy recovery from landfill gas through the production of pipeline-quality RNG. It adapts to any variations in the composition and flow rate of landfill gas, and can upgrade landfill gas with up to 30% nitrogen. Seventeen WAGABOX^® units are in operation in France, Canada and Spain, and fifteen more under construction in the United States, France and Canada.

Casella, is amongst the Northeast's largest recyclers and is an experienced fully integrated resource management company, operating nine landfills in the northeasternUnited States.

John W. Casella, Chairman and CEO of Casella Waste Systems, Inc.: "Working with Waga Energy is a great opportunity for our company to further enhance our strategy around resource management and sustainability. 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."

Mathieu Lefebvre, Chairman and CEO of Waga Energy: "It is an immense honor to partner with Casella, a highly respected leader of the waste management industry in the United States. The months of work carried out between our teams to develop these sites have allowed us to discover an organization with a clear mission, rooted in the territories where Casella operates and committed to the preservation of the common good. These shared values between our companies are an essential foundation for the success of these circular economy projects and a lasting collaboration. This partnership is a major step in the global deployment of the WAGABOX^® solution, for the energy transition and the fight against climate change."
