Air Liquide Cuts Ribbon on Landfill Gas-to-RNG Plant in Mississippi


On Friday, Air Liquide held a ribbon-cutting ceremony for the grand opening of its landfill gas to renewable natural gas (RNG) purification plant in Walnut, Miss.

Air Liquide, which is based out of France, designed and built the large-scale biomethane production plant. It is located at the Northeast Mississippi Landfill (NEML) site, which is owned by Northeast Mississippi Solid Waste Management Authority and operated by Waste Connections Inc.

The biomethane plant purifies household waste gas provided by the landfill and converts it into RNG. Air Liquide currently operates 10 biomethane production units worldwide.

“Air Liquide is committed to providing reliable, secure and sustainable energy solutions for our customers and global society, and we firmly believe in the power of renewable energy as a cornerstone of this energy transformation,” says Michael Graff, executive vice president and executive committee member of Air Liquide S.A. and chairman and CEO of American Air Liquide Holdings Inc. “We are proud to offer innovative and sustainable technologies that strengthen this commitment across the U.S.”
