Waste Commission of Scott County, Linwood Mining and Minerals, and Waga Energy, in partnership with the American Biogas Council, officially inaugurated a Renewable Natural Gas (RNG) unit at the Scott Area Landfill. The facility will produce over 205,000 MMBtu (60 GWh) of RNG annually, avoiding 15,800 tons of CO emissions - a major milestone for Scott County's energy transition.
On Wednesday November 19th, 2025, Ken Beck, Chair of the Waste Commission of Scott County, Bryce Stalcup, Executive Director of the Waste Commission of Scott County, Mike Bush, President of Linwood Mining and Minerals, and Guénaël Prince, CEO of Waga Energy Inc., along with Patrick Serfass, Executive Director of the American Biogas Council, inaugurate the Renewable Natural Gas (RNG) Unit at the Scott Area Landfill in Davenport, Iowa.
Commissioned in October 2025, the Scott County RNG plant is operated by Waga Energy, a global leader in landfill gas-to-RNG, and uses Waga Energy's patented WAGABOX® technology to upgrade landfill gas into pipeline-quality RNG. The gas is injected directly into the MidAmerican Energy pipeline, providing a local, renewable alternative to fossil natural gas.
Key figures
- 205,000 MMBtu (60 GWh) per year of installed capacity of RNG - equivalent to the energy contained in about 1.5 million gallons of diesel fuel
- 15,800 tons of CO2 equivalent emissions avoided annually through the substitution of fossil natural gas[1]
- 185,000 tons of waste processed each year at the Scott Area Landfill
Public-private cooperation
The project illustrates a successful collaboration between public and private stakeholders. The landfill is operated by the Waste Commission of Scott County on a Linwood Mining and Minerals property.Waga Energy designed, built, owns and operates the facility under a 20-year agreement, sharing revenues with the Waste Commission of Scott County and Linwood Mining and Minerals.This partnership optimizes methane capture and enhances renewable energy production for the region. The project contributes to the fight against climate change. A key pillar for the energy transition, RNG is a local, renewable energy source that can substitute fossil-based fuels in transportation, industry, and heating.
