I would like to know where to take used refrigeration oil for recycling or disposal. Recently I called my refrigeration supply house and asked what to do with my used oil. I was told to call my local municipality. They gave me another number to call, but I never did find out where to get rid of the oil. Can you advise? Answer: By John Lawler Nu-Calgon St. Louis, MO

The disposal of used refrigeration oil is obviously a concern, given the fact that it probably contains varying amounts of refrigerant. At this point, one of the better known sources for handling used oil is a national company named Safety Kleen Corp. Usually they can be located via your local phone book. There may be other such resources, but Safety Kleen Corp. seems to be one of the better known sources.
