Abstract
Methods and apparatus for treating waste with radio frequency include a wall defining a radio frequency treatment chamber through which waste may be passed. A source of radio frequency energy energizes the radio frequency treatment chamber to heat the waste and drive off vapors therefrom leaving solid residue to be disposed of. A guard heater and/or insulation maintains the wall at substantially the same temperature as the waste being heated by the radio frequency to prevent vapors from condensing on the waste.
