Texas Army National Guard

Year Submitted: 2003

Process: Antifreeze Recycling

Industry: Government Agency-Includes Military

Wastes Reduced: Coolant

Substance: Antifreeze

Equipment: Collant Purification System

Location: Camp Mabry, Austin TX

Contact: LTC Don Tryce

Phone: (512) 465-5001 ext 5717


In November 1993, the Texas Army National Guard purchased Model C-1 Cool'r Clean'r Coolant Purification System from Kasco Fuel Maintenance. The unit was placed in operation in December 1993.

P2 Application:

The Model C-1 is designed to recycle 55 gallons of antifreeze to military specifications in eight hours. This unit is multi functional. It can process bulk cold coolant or hot coolant directly from the vehicle. Model C-1 uses both a filtration and deionization process. It removes all contaminant, including all dissolved solids.The Model C-1 requires the purchase of new additives and operators must have experience on how much to add to recycled antifreeze to meet military specifications. Additives are needed for every three hundred gallons at a cost of $96 per two ionizing tanks. Volumes of coolant may vary slightly due to filter conditions.

Environmental Benefits:

The C-1 unit is recycling an average of 1,300 gallons per year of antifreeze.

Details of Reductions

Additional Information :

The C-1 unit was purchased for $10,000 in 1993. Pure ethylene glycol is purchased at $4.50/gallon and mixed at a 50-50 ratio with water for antifreeze. Used antifreeze costs $.25/gallon for disposal. Chemical additives are approximately $.32 per gallon of antifreeze processed. At these costs the unit pays for itself after processing 1,718 gallons of antifreeze. It takes 12 hours to recycle one 55-gallon drum.
