The paper describes the results of field testing of filtration and distillation technologies for recycling automotive and heavy-duty engine coolant (antifreeze) offered by two manufacturers. The data support the Agency's emphasis on reducing the generation of hazardous and non-hazardous waste by encouraging study and development of methods to recover and reuse ethylene glycol coolant. The results may be useful to federal, state and local environmental agencies that are considering reducing or eliminating ethylene glycol wastes by recycling. The results may also be useful to those in the vehicle maintenance industry who may be considering engine coolant recycling programs. (Copyright (c) 1993 - Air & Waste Management Association.)
