G2 Energy, Waga Energy to produce RNG at 2 Recology landfills

G2 Energy, a developer and operator of landfill gas projects, has selected Waga Energy, a global producer of renewable natural gas (RNG) from landfills, to develop RNG projects at two landfills owned and operated by Recology, an integrated resource recovery company providing materials collection, processing and outreach and education to customers along the West Coast.

Under this agreement, Waga Energy will finance, build, own and operate two RNG production facilities using its patented WagaBox technology. The first facility will be located at the Ostrom Road Landfill in Wheatland, California, and will produce up to 420,000 metric million British thermal units (MMBtu), or 123 gigawatt hours (GWh) annually. The second facility will be installed at the Hay Road Landfill in Vacaville, California, and will produce up to 630,000 MMBtu (185 GWh) annually. Both projects will be interconnected with Pacific Gas & Electric (PG&E) to inject RNG into the local natural gas network.

The two facilities are expected to be commissioned in 2026 and will jointly offset approximately 70,000 tons of CO2 equivalent emissions each year, equivalent to the annual emissions from around 8,500 homes’ energy use for one year, or equivalent to the greenhouse gas emissions from almost 15,000 gasoline-powered passenger vehicles driven for one year.

The landfill gas from Recology’s two active landfills is currently being used to produce electricity. Upgrading the landfill gas to RNG using the WagaBox technology will increase the energy conversion efficiency, and provide a local, renewable alternative to fossil natural gas. Waga Energy’s patented technology combines membrane filtration with cryogenic distillation, maximizing the renewable energy production of landfills by ensuring the production of pipeline-quality RNG, regardless of landfill gas variations in flow rate and composition.

“At G2 Energy, we are excited to continue our long-term partnership with Recology to find the highest and best use for this landfill gas. Making the most of this waste gas is part of our adoption of the goal of zero waste”, says Peter Wachtell, a founding member of G2.

“This partnership is a win for our planet and the communities we serve, showing what’s possible when innovation meets purpose. By transforming landfill gas into RNG, we’re reducing emissions, creating clean energy and advancing Recology’s mission to build a more sustainable future,” says Recology CEO Salvatore M. Coniglio. “The completion of these projects will make significant progress towards achieving our goal to use 75 percent of the landfill gas we collect to generate renewable energy by 2028.”

Guenael Prince, CEO of Waga Energy Inc., adds, “We are thrilled to partner with G2 Energy and Recology to develop the first two WagaBox units in California that reduce greenhouse gas emissions from waste while displacing fossil fuels with a renewable and local source of energy. The RNG produced will directly contribute to California’s decarbonization goals and support the state’s energy transition.”
