Deicerman, well, if you say so. But the open application of any MEG and DEG is strictly forbidden in the complete European Community. Also, the biggest manufacturers of such products (Kemira, Kilfrost, Clariant, etc.) do not have MEG and DEWG based products in their portfolio.
Who is the manufacturer and which airport?
The only exemption form all the environmental rules I know is with some airpots operated by the military. But alos this is more than restricted.
