Waga Energy, a global expert in the production of renewable natural gas (RNG) from landfills, and Casella Waste Systems, Inc. (CWST), a regional solid waste, recycling and resource management services company in the US, signed an agreement on 10 July to develop RNG projects at three CWST landfills.
As part of the 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 US Environmental Protection Agency (EPA), according to the companies.
WAGABOX® technology is the result of 15 years of development, and maximises 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, said Waga Energy. 17 WAGABOX® units are in operation in France, Canada and Spain, and fifteen more under construction in the United States, France and Canada.
CWST is amongst the Northeast's largest recyclers and is an experienced fully integrated resource management company, operating nine landfills in the northeastern US.
John W. Casella, chairman and CEO of CWST, said: "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, commented: "It is an immense honour 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 organisation 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."
