Why aircraft de-icing on the pads is important to us...

The specially-designed de-icing pads at MSP are a critical piece of the infrastructure for efficient and environmentally-friendly operations. Aircraft are de-iced at contained locations at the terminal gates, on the ramps, and at the pads. We measure the amount of aircraft de-icing fluid (glycol) applied at the airport, and then compare that number to the amount applied at the pads.
Our de-icing pads provide us and our partners with the most effective method to recover glycol for processing and recycling during the de-icing season, which runs from the fall of one year into the spring of the next year. During the 2016-2017 de-icing season, 81% of collected glycol was processed through the recycling system with the remainder sent for treatment.
