Archaea’s Kentucky landfill-to-RNG project operational
The project, developed in partnership with Rumpke Waste & Recycling, is located in Ashland, Kentucky, and can now produce 2,300 MMBtu per day of pipeline-quality RNG, providing a reliable source of feedstock and transforming the site into a renewable energy hub.
Archaea’s technical and operational team launched the project in just four months after acquiring it from another developer. Until now, the plant was unable to upgrade its landfill gas to meet pipeline specifications.
“Our mission was multi-faceted,” said Nick Stork, Archaea Energy’s co-founder and CEO, “to ensure that the Boyd County biogas project is fully compliant, operational and profitable and that it benefits the tri-state communities in Kentucky, Ohio, and West Virginia.
“Our experienced team helps landfills and off-take partners harness the power of RNG, guided by the company’s values and a strong commitment to sustainability and decarbonisation.”
The landfill currently processes around 1,400 tons of waste a day from the tri-state area within a 75-mile radius. Previous attempts by other RNG developers to increase the landfill’s methane recovery levels by implementing a nitrogen-rejection process were unsuccessful in meeting the specifications for pipeline-quality RNG without heavy blending with natural gas, Archaea said.
The company applied its knowledge of gas separation and nitrogen rejection to repair and optimise the facility to remove inert components and convert the raw landfill gas into RNG with high levels of methane recovery.
Charlie Anderson, Archaea’s co-founder and director of gas processing, commented: “Leveraging the combined experience of our technical and operational teams across over 30 biogas projects, we turned a very challenging RNG plant into a revenue-producing renewable energy project in a short timeframe.”
