Waste Today – Ameresco LFG-to-RNG plant starts operations at Republic landfill

Ameresco Inc., a cleantech integrator specializing in energy efficiency and renewable energy, has achieved commercial operation at its landfill gas (LFG) to renewable natural gas plant at Republic Services’ Benson Valley Landfill in Frankfort, Kentucky.

The Benson Valley facility has a nameplate capacity in excess of 483,552 dekatherms per year and is capable of processing 2,000 standard cubic feet per minute of raw LFG.

Ameresco broke ground on the project in June 2022 and reached commercial operation this August. As a result of the long-term partnership, Benson Valley Landfill will reduce 27,440 tons of carbon dioxide emissions per year, a figure that is roughly equivalent to the carbon sequestered by planting 325,899 acres of forests or 31 million gallons of gasoline not being combusted.

“At Republic Services, our vision is to partner with customers to create a more sustainable world now and for future generations,” Republic Services Area President Larson Richardson says. “Our long-standing partnership with Ameresco enables us to capture naturally occurring gas created by decomposing waste in our landfill and convert that gas into a low-carbon fuel source that reduces greenhouse gas emissions. The Benson Valley RNG [renewable natural gas] facility is just another example of us living our values; we are sustainability in action.”
