Landfills

Landfills are the third largest source of methane emissions in the U.S. and are designated as greenhouse gas sources that must be monitored and controlled. We manufacture Scott™ brand methane calibration gas standards as EPA protocol gases designed to help you comply and accurately measure methane emissions from a landfill. Air Liquide's MEDAL™ biogaz membrane system offers a uniquely simple way to process biogas and landfill gases and selectively separate methane and carbon dioxide and recover valuable methane.
