Republic Services expands renewable natural gas reach into Europe

Republic Services pushed landfill gas beyond North America for the first time, after Neogenyx Fuels delivered ISCC-certified renewable natural gas from a Republic landfill into European compliance markets. The move gives the waste giant another outlet for methane captured at its landfills, where Republic says it already converts gas to energy at 65 sites and has gas collection wells across about 90% of active landfill acreage.

Republic has been building the RNG platform for years. The company says programs to harness landfill gas for RNG started in 2008-2013, with the McCarty Landfill as its first collection and processing plant. Republic has set a target to deploy more than 100 landfill-gas-to-RNG projects by 2030, a buildout that turns flare gas into saleable molecules, environmental attributes and, in some cases, transportation fuel.

The rollup is already showing up in project milestones. Ameresco said Republic's McCarty Road Landfill RNG plant reached commercial operation in Q2 2021. In June 2024, Republic and Archaea Energy marked their first RNG plant in Fort Wayne, Indiana, which was expected to process up to 6,400 scfm and enough gas to heat more than 25,000 homes annually, according to the U.S. Environmental Protection Agency's Landfill Gas Energy Benefits Calculator. In May 2025, OPAL Fuels announced a joint venture with a Republic affiliate for a project at the Charlotte Motor Speedway Landfill in Concord, North Carolina, with an initial annual design capacity of about 1.4 million MMBtu. In July 2025, Republic and Ameresco said the Lee County facility was their 15th completed renewable energy project together, and Republic said RNG from the site entered a natural gas transmission pipeline at the end of June 2025.

The European delivery matters because it suggests Republic can monetize landfill gas in premium compliance markets, not just in North American vehicle-fuel channels. That expands the customer base for captured methane and could strengthen the economics of the gas-collection network that underpins Republic's landfill moat. Republic said its 2024 greenhouse gas emissions fell 20% from the 2017 baseline, beating its interim 2025 target of a 10% reduction. Clean Energy Fuels had already praised Republic's expanded use of Redeem RNG in 2019, and the latest cross-border sale gives the stock a harder asset-backed story: landfill gas volumes, certified attributes and multiple outlets for each project rather than a single sustainability narrative.
