Archaea Energy, a unit of bp, has announced the commencement of operations at its largest renewable natural gas (RNG) plant to date, located in Shawnee, Kansas, US.
The facility, which is fully owned by Archaea, utilises the company’s proprietary Archaea Modular Design (AMD) to convert landfill gas into RNG.
Positioned adjacent to a privately owned landfill, the Shawnee plant captures landfill gas – a greenhouse gas by-product from waste decomposition – and processes it into RNG.
This plant has the capacity to handle 9,600scf/min of landfill gas, translating to enough RNG to heat approximately 38,000 homes each year, as per the Environmental Protection Agency’s Landfill Gas Energy Benefits Calculator.
According to bp, the AMD technology marks a departure from the traditional custom-built RNG facilities, allowing for more rapid construction with its skid-mounted, interchangeable components.
The Shawnee plant is notably three-times larger than Archaea’s AMD plant in Medora, Indiana, which commenced operations in October 2023.

By GlobalDataThe Medora facility was the first to launch following bp’s substantial acquisition of Archaea Energy in 2022 for $4.1bn (£3.28bn).
With this strategic move, bp has positioned itself as one of the key RNG producers in the US.
In 2023, the company reported an 80% increase in global biogas supply volumes, a significant rise attributed to the Archaea acquisition.
