Ameresco, a leading provider of energy solutions dedicated to helping customers transition to cleaner energy, announced that its newest renewable natural gas (RNG) facility is now operational. This project was developed through a partnership with Republic Services, a major company in environmental services. The new facility is located at the County Landfill in Dixon, Illinois.
This marks the 15th renewable energy project completed through the collaboration between Ameresco and Republic Services, with more projects currently in progress, permitting, or construction.
In late June 2025, RNG produced at the Lee County facility was successfully injected into a natural gas pipeline. The plant captures landfill gas and processes it into pipeline-quality RNG.
The facility is capable of processing 4,500 cubic feet of raw landfill gas per minute. It will turn what used to be flared into a valuable source of renewable energy.
Environmental estimates suggest that this project will cut carbon dioxide emissions by over 61,000 metric tons each year. That’s equivalent to removing emissions from over 70 million gallons of gasoline or about 1.5 million barrels of oil. This helps reduce reliance on fossil fuels and promotes sustainability by converting waste into clean energy.
Tim Oudman, Senior Vice President of Sustainability Innovations at Republic Services, said, “The Lee County RNG plant demonstrates our commitment to sustainability and creating real decarbonization solutions for our communities. Our ongoing partnership with Ameresco continues to produce projects that help build a more sustainable world.
This project supports both Illinois’ renewable energy goals and Republic Services’ sustainability commitments. Illinois aims to reach 40% renewable energy by 2030 and 100% clean energy by 2050. Meanwhile, Republic Services has pledged to reuse at least half of the biogas it produces at all locations by 2030.
