From Garbage to Gas: Waga Energy’s U.S. Revolution

French firm Waga Energy turns U.S. landfill methane into clean fuel, boosting renewable gas momentum

17 Oct 2025

America’s clean energy story has found an unlikely hero: garbage. A French company called Waga Energy is proving that trash can do more than fill landfills. It can fuel homes, cut emissions, and drive the next phase of the renewable gas market.

At the heart of this shift is Waga’s WAGABOX technology, a system that captures methane from decomposing waste and converts it into renewable natural gas, or RNG. Using a blend of advanced filtration and cryogenic cooling, the process upgrades even low-quality landfill gas into pipeline-grade fuel. For smaller waste sites once deemed too costly to develop, this breakthrough turns forgotten emissions into valuable resources.

The company’s first American plant, launched in Steuben County, New York, in 2024, already produces enough clean fuel to heat thousands of homes. Another facility in Iowa is set to begin operations in 2025, with several more in development. Together, these projects could meaningfully expand regional clean gas supplies while creating new revenue for local communities.

“This technology changes the game for smaller landfills,” said Matthew Todd of the American Biogas Council. “It gives communities a real chance to turn waste into opportunity.”

Federal incentives from the Inflation Reduction Act are helping draw investors eager to back renewable gas infrastructure. Costs and utility connection hurdles remain, but the sector’s momentum is growing fast.

As Waga Energy scales across the U.S., it is reshaping the way Americans think about trash, not as waste but as a clean energy asset waiting to be tapped.
