Select a step where Air Liquide intervenes in your value chain


Landfills 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.
