Archaea Energy’s Assai plant is the largest renewable natural gas (RNG) plant in the US, which exceeded its 2023 RNG production goal of 4 million MMBtus. We are in the planning stages to drill a carbon capture and sequestration appraisal well near Assai, to determine whether carbon dioxide sequestration could be feasible at this site. The plant and facilities that support the plant in Pennsylvania employ 23 full-time individuals.
Elsewhere in Pennsylvania, Archaea and its partner, Waste Connections, opened an RNG plant in the Lower Saucon Township that came online in July 2024. Adjacent to the Bethlehem Landfill, it can process up to 3,500 standard cubic feet of landfill gas per minute (scfm) into RNG – enough gas to heat more than 14,000 homes annually, according to the EPA’s Landfill Gas Energy Benefits Calculator.
Archaea opened a third RNG plant at the Commonwealth Environmental Systems Landfill with its partner, UGI Energy Services, in September 2024. This plant can process up to 9,600 scfm of landfill gas into RNG – enough gas to heat more than 39,000 homes annually, according to the EPA’s Landfill Gas to Energy Benefits Calculator.
Among the waste decomposing at farms and landfills across the US, bp saw something it liked: an abundant source of energy, one that could provide the company with a new revenue stream and another way to help reduce greenhouse gas emissions.
