In the United States (US), G2 Energy, LLC, a developer and operator of landfill gas (LFG) projects that prioritize beneficial use of the gas, has selected Waga Energy, Inc., the US subsidiary of France-headed landfill gas to renewable natural gas (RNG) technology provider Waga Energy SA, to develop RNG projects on two landfills owned and operated by Recology Inc., 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 sited at the two Recology landfills.
The first facility will be located at the Ostrom Road Landfill in Wheatland, CA, and is estimated to produce up to 420,000 MMBtu (123 GWh) annually.
The second facility will be installed at the Hay Road Landfill in Vacaville, CA, and is estimated to 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, and are expected to be commissioned in 2026.
The two units combined will offset approximately 70,000 tonnes of carbon dioxide equivalent (CO2eq) emissions annually.
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 a goal of Zero Waste, said Peter Wachtell, one of the founding members of G2 Energy.
The LFG from the two Recology active landfills is currently being used to produce electricity.
Upgrading the LFG to RNG using the WAGABOX technology will increase the energy conversion efficiency, and provide a local, renewable alternative to fossil natural gas.
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. 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, said Salvatore M. Coniglio, CEO at Recology.
As a result of 15 years of development, Waga Energy’s patented WAGABOX technology revolutionizes landfill gas upgrading by combining membrane filtration with cryogenic distillation.
It maximizes the renewable energy production of landfills by ensuring the production of pipeline-quality RNG, regardless of landfill gas variations in flow rate and composition.
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. We look forward to further expanding our solution throughout California where landfills represent a significant potential for RNG production by leveraging our WAGABOX technology, said Guenael Prince, CEO of Waga Energy Inc.
