ABSTRACT:
An apparatus for separating hazardous volatile and semi-volatile organic materials from contaminated solid waste by-products is comprised of an evaporation/vacuum heating chamber that is designed to hold a sample of the solid waste product on a batch basis, a microwave generator that subjects the sample of waste product to microwave energy, an electrical resistance type heating system that heats portions of the waste product sample adjacent the container holding the sample that are not subjected to the full strength of the microwaves, and an evacuation/condensing system that draws off volatile vapors distilled from the waste sample and condenses and collects the hazardous volatile organic materials, leaving a resultant waste product cake, dry and virtually free of volatile matter in the evaporation/vacuum heating chamber.
