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 CO₂ 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.

Ken Beck, Chair of Waste Commission of Scott County: 
“Just like the Waste Commission is a partnership, this project is a partnership. The Commissioners are pleased to give our support of working with Linwood Mining and Minerals and Waga Energy on this innovative and exciting community development.”

Bryce Stalcup, Executive Director of Waste Commission of Scott County: 
“This Public/Private partnership means cleaner air, better use of natural resources, and proof that sustainability and economic responsibility can go hand in hand. This isn’t just new infrastructure; it’s a milestone in how we think about resources, partnerships, and our shared future. Scott County doesn’t just talk about sustainability and innovation—we build it.”

Mike Bush, President of Linwood Mining and Minerals: 
“This project shows what can be achieved when organizations work together toward a clear goal. We’re proud to partner with the Waste Commission and Waga Energy to bring this renewable energy resource to Scott County.”

Guénaël Prince, CEO of Waga Energy Inc: 
“We are very proud to inaugurate this WAGABOX® unit at the Scott Area Landfill: it embodies the power of public-private collaboration , and demonstrates Waga Energy's expertise, through its innovative technology, to develop RNG projects on smaller landfills. Together with the Waste Commission of Scott County and Linwood Mining & Minerals Corp. we’re fighting against climate change and advancing the energy transition. We’re delighted to provide advanced lower carbon technology that serves the local community.”
