  • Abstract:
    Numerous advancements 1n aircraft deicing/anti-icing fluids, application methodologies, training, and deicing/anti-icing equipment have emerged in recent years; however, the undesirable effects of deicing fluid runoff on the environment remain a challenge. Although most proper disposal operations includes precise metering on the resultant deicing operation runoff into sewer systems in amounts deemed not ecologically detrimental, this practice· is not considered a suitable solution by all. Costs associated with glycol runoff may provide additional incentive for recycling. Capturing spent glycols for recycling into aircraft usable, certified deicing/anti-icing products or marketable glycols for nonaviation use is anticipated to ease the stress of local environs and water treatment plants. Practices and procedures addressing the recycling and reuse of these glycols are the underlying focus of this investigation. The primary objective of this study was to globally investigate and document spent glycol recycling methods and practices, including Asian, former Soviet bloc countries, and other areas of the world not within the purview of current SAE/ISO fluid standards. As a minimum a combination of 140 worldwide airports, airlines, air carriers, recovery vehicles suppliers, recycling equipment vendors, recycling equipment operators, and vendors of equipment used for diversion and containment of spent aircraft deicing fluid (ADF) were sent questionnaires. Technical and economic information was collected from questionnaires, vendor literature, government reports, communication via facsimiles, internet e-mailings, phone conferences, on-site meetings, and the experience of the author. Study results provide information associated with establishing an on-site or remote glycol recycling facility, what can be expected from such a facility, utilization of the refined glycol, and a method for reprocessing into aircraft deicing/anti-icing fluid.
