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.
Canada’s International Water-Guard Industries has received JAA approval as a JAR 145-accepted facility for maintenance of IWG aircraft components.
