A process and apparatus for the destructive distillation of high molecular weight organic materials such as organic wastes, particularly those containing hydrocarbon groups, using ultrasonic and microwave generators together to irradiate, and molecularly disperse the organic molecules in the organic materials. At least initially a portion of the organic materials are preferably irradiated with a laser beam or other initiator to initiate molecular motion in the organic materials and produce elemental carbon in situ from the organic materials so that the process will begin rapidly. Carbon and/or particulate catalysts which promote or increase the absorption of microwaves are preferably admixed with the organic materials. Also described are condenser means for removal of oily higher molecular weight volatilization products and water electrolysis means for providing oxygen for the oxidation of carbon materials in the volatilization products and to provide hydrogen in the gaseous volatilization products in order to provide clean gaseous volatilization products having a high fuel value. Charcoal, tars, resins and pure carbon are also by-products of the process.
