Archaea Energy Inc

A maker of renewable natural gas, Archaea Energy captures methane from landfills and dairy farms and purifies it into pipeline-quality fuel for trucks, homes, and industry, ranking among the largest producers of its kind in the United States. Founded in 2018 with roots from Pennsylvania's Noble Environmental waste firm, the company was acquired by energy giant BP in 2022. Its name honors archaea, the ancient single-celled microbes whose methane-producing biology mirrors the gas the company cleans up.
