In a landmark public-private partnership, Waga Energy, Scott County Waste Commission, and Linwood Mining and Minerals have commissioned a cutting-edge biomethane production unit in Davenport, Iowa. The facility, powered by Waga Energy’s patented WAGABOX® technology, converts landfill gas into renewable biomethane—offsetting 16,800 tons of CO2 annually and injecting clean energy into MidAmerican Energy’s grid. With a 20-year operational horizon, this project exemplifies how waste-to-energy solutions can drive both economic and environmental wins.
How Does This Biomethane Facility Transform Waste into Energy?
The Davenport landfill processes 185,000 tons of waste yearly from Scott County and 17 neighboring municipalities. Historically, methane emissions from decomposing waste contributed to greenhouse gas effects. Now, Waga Energy’s WAGABOX® system captures this methane and upgrades it to pipeline-quality biomethane—a renewable substitute for fossil natural gas. The facility’s annual output of 60 GWh could replace over 6 million liters of diesel fuel, making it a game-changer for regional decarbonization efforts.
Why Is This Public-Private Partnership Significant?
Unlike traditional landfill gas projects that merely Flare methane, this collaboration creates shared revenue streams. Waga Energy owns and operates the unit, splitting profits with Scott County Waste Commission and landowner Linwood Mining. "We’re turning liabilities into assets," said Bryce Stalcup, the Commission’s Executive Director. The 20-year agreement ensures long-term stability while aligning with Iowa’s renewable energy targets.
What Makes WAGABOX® Technology Unique?
Developed over a decade by French cleantech firm Waga Energy, the system combines membrane filtration and cryogenic distillation to purify landfill gas with 90%+ efficiency. Unlike conventional methods, it handles variable gas compositions—critical for aging landfills. Guénaël Prince of Waga Energy notes: "This Iowa facility mirrors our successful deployments in France and Canada, proving scalability across regulatory environments."

Local Stakeholders Weigh In
Mike Bush of Linwood Mining emphasized their commitment to "responsible land use," while Scott County officials highlighted the project’s alignment with Iowa’s. Interestingly, the deal structure could become a template for other rural counties—where landfill gas projects often struggle with financing.
The Bigger Picture: Biomethane in the Energy Transition
As of October 2025, over 1,200 biomethane plants operate globally (per). What sets this Iowa project apart? Its hybrid funding model and focus on community benefits. The biomethane supplements MidAmerican’s grid, potentially lowering energy costs for 12,000+ households. Still, challenges remain—like maintaining consistent gas quality as landfill chemistry evolves over decades.
FAQs About the Davenport Biomethane Project
Who owns the WAGABOX® facility?
Waga Energy retains ownership and operational control, sharing revenue with Scott County and Linwood Mining.
How does this compare to other renewable energy sources?
Biomethane provides baseload power unlike intermittent solar/wind, but depends on waste volumes. It’s currently 20-30% cheaper than hydrogen alternatives per BTU.
Are there expansion plans?
Waga Energy may deploy additional modules if gas production increases, though no formal announcements exist as of October 2025.
