The Cape May County Municipal Utilities Authority (CMCMUA) has selected France-based Waga Energy to build, own and operate a renewable natural gas (RNG) production unit at the Secure Sanitary Landfill in Cape May County, New Jersey.

The facility will use Waga Energy’s Wagabox technology to convert landfill gas into RNG, which will be injected into the local pipeline for a 20-year term. Waga Energy was selected in early 2025 following a request for proposals issued by CMCMUA. The company’s Wagabox technology combines membrane filtration with cryogenic distillation, which it says maximizes the renewable energy production of landfills by ensuring the production of pipeline-quality RNG, regardless of landfill gas variation sin flow and composition.

The company says the Wagabox unit is designed to process up to 1,000 standard cubic feet per minute (scfm) of landfill gas, producing approximately 205,000 million British thermal units (mmbtu) of RNG annually.

According to Waga Energy, the project is expected to reduce up to 15,800 metric tons of CO₂ equivalent emissions annually by displacing the use of fossil fuels.

“We are proud to partner with the Cape May County Municipal Utilities Authority on our first Wagabox project in New Jersey, an initiative leading the way in renewable energy production for the state,” Waga Energy Co-founder and CEO Guénaël Prince says. “This project will reduce local emissions, improve air quality and support the circular economy. We look forward to partnering with the CMCMUA to bring this project to life.”

The CMCMUA Secure Sanitary Landfill serves all sixteen municipalities within Cape May County. The year-round population of the county is approximately 98,000 residents, but Waga Energy says the county’s popularity as a vacation destination draws additional crowds over the summer months, increasing the population to more than 750,000.

The CMCMUA Secure Sanitary Landfill accepts roughly 180,000 tons of waste annually, and the landfill gas is currently used for power generation through a CHP engine. Waga Energy says the project’s RNG production will maximize the beneficial use of landfill gas generated from the degradation of waste in the landfill, while supplying renewable energy to support the decarbonization of transport.

Waga Energy says revenue from the project will support the CMCMUA’s continued maintenance and investment in the landfill gas conveyance and collection system.

“The CMCMUA is advancing its commitment to the beneficial use of landfill gas by partnering with Waga Energy Inc. and integrating their Wagabox technology,” CMCMUA Executive Director Joseph V. Rizzuto says. “This collaboration is a perfect fit for the CMCMUA’s vision of actively pursuing and implementing innovative and environmentally sustainable solid waste systems.”
