Kilfrost (Hall 4 Stand G4) is introducing what it claims to be the first aircraft de-icing fluid made from sustainable sources. The new corn-based DF Sustain fluid is an environmentally friendly alternative to monopropylene glycol and it has already been approved by aviation authorities in the U.S. and Japan.
Responding to new Environmental Protection Agency guidelines that could eventually become law, Octagon Process has developed a Type 1 de-icer fluid that uses less propylene glycol than typical fluids. According to Octagon president Joe McGrail, when propylene glycol gets into wetlands, it breaks down and microorganisms form and attack the glycol.
UK-based Kilfrost, which is celebrating 66 years since it helped introduce the first in-flight de-icing systems to keep wings frost and ice free, has developed DFsustain [The initials DF stand for de-icing fluid.–Ed.] from a corn-based glycol called Susterra, developed by DuPont Tate and Lyle BioProducts, rather than the more traditional crude-oil derived glycol.
