Archaea Energy starts up world’s largest RNG project in Pennsylvania

In Texas, Archaea Energy Inc. has successfully started-up Project Assai, an RNG facility located at the Keystone Sanitary Landfill in Dunmore, Pennsylvania. Pipeline-quality RNG has been produced and commercial operations were achieved on December 30, 2021. Assai is now the highest capacity operational RNG facility in the world.

Assai was successfully constructed, commissioned, and completed within budget and in under two years, a timeline materially shorter than industry averages for landfill gas to RNG development projects, including projects of much smaller size. Assai has an inlet capacity of 22,500 scfm and combines landfill gas flows from the Keystone Sanitary Landfill and the Waste Management Alliance Landfill. Assai is expected to reduce CO2 emissions by over 200,000 metric tons annually and significantly reduce air pollutants, many by over 90%.
