RNG facility opens in Iowa

A new renewable natural gas (RNG) facility at the Scott Area Landfill in Iowa, US.
The plant, a collaboration between the Waste Commission of Scott County, Linwood Mining and Minerals, and Waga Energy, in partnership with the American Biogas Council, is expected to produce over 205,000 MMBtu (60 GWh) of RNG annually, avoiding 15,800 tons of CO₂ emissions.
The inauguration ceremony on 19 November saw Ken Beck, Chair of the Waste Commission of Scott County, Bryce Stalcup, Executive Director of the Commission, Mike Bush, President of Linwood Mining and Minerals, and Guénaël Prince, CEO of Waga Energy Inc., joined by Patrick Serfass, Executive Director of the American Biogas Council, officially open the facility.
Commissioned in October 2025, the Scott County RNG plant is operated by Waga Energy. Using Waga Energy’s WAGABOX technology, the facility upgrades landfill gas into pipeline-quality RNG, which is injected directly into the MidAmerican Energy pipeline, offering a local, renewable alternative to fossil natural gas.
The landfill is operated by the Waste Commission of Scott County on land owned by Linwood Mining and Minerals.
Waga Energy designed, built, owns, and operates the facility under a 20-year agreement, sharing revenues with the other stakeholders.
The collaboration optimises methane capture and increases renewable energy production in the region, contributing to the fight against climate change.
Ken Beck, Chair of the Waste Commission of Scott County, said: “Just like the Waste Commission is a partnership, this project is a partnership. We are pleased to work with Linwood Mining and Minerals and Waga Energy on this innovative and exciting community development.”
Guénaël Prince, CEO of Waga Energy Inc., commented: “We are proud to inaugurate this WAGABOX unit at the Scott Area Landfill. It demonstrates the power of public-private collaboration and Waga Energy's expertise in developing RNG projects on smaller landfills.
"Together with the Waste Commission of Scott County and Linwood Mining and Minerals, we are fighting climate change and advancing the energy transition, providing advanced, lower-carbon technology for the local community.”
