    • A process for decomposing polychlorinated biphenyls is provided to conduct the decomposition reaction safely and consume energy less by carrying out a decomposition reaction at an atmospheric pressure and a relatively low temperature, and improve decomposition efficiency greatly and prevent the generation of toxic substances such as dioxin by substantially reducing the decomposition time. A process for decomposing polychlorinated biphenyls comprises: a mixing step of mixing at least one of a metal catalyst and a hydrogen shift agent, an alkali catalyst, and an insulating oil containing polychlorinated biphenyls; and a decomposition step of reacting the mixture of the mixing step in a heating atmosphere to decompose polychlorinated biphenyls. The process comprises mixing 10 to 500 mg of the metal catalyst, 0.1 to 10 g of the alkali catalyst, and 0.1 to 20 g of the polychlorinated biphenyls based on 55 ppm of the polychlorinated biphenyls' concentration in the mixing step. The hydrogen shift agent is at least one selected from Anthracene, Phenanthrene, Tetraisopropyl benzene, and 9,10-Dihydroanthracene. The decomposition step comprises rising reaction temperature of the mixture of the mixing step at a rate of 0.1 to 20 deg.C/min under an inert gas flow, and constantly maintaining the reaction temperature to decompose the polychlorinated biphenyls.

    • Apparatus (10) and a method for vitrifying hazardous waste includes a melting vessel (12) in which hazardous waste and any other necessary components for forming a glassy mixture upon heating are introduced for heating by a heater (38), and a metallic containment vessel (46) of the apparatus receives the melting vessel so as to receive and contain any material that exits the melting vessel upon failure. Any failure of the melting vessel (12) is detected by a sensor (48). Different embodiments of the heater (38) provide current flow through molten material (18) being heated, induction heating and electric resistance heating. A stirrer (39) can be utilized to mix the material (18) during the heating. The containment vessel (46) is preferably hermetically sealed around the melting vessel (12) to contain gases as well as any melted material received from the failed melting vessel (12). The sensing of the failure can be either by a pressure change in the hermetically sealed chamber (58) or by sensing of the presence of material received by the containment vessel (46) from the failed melting vessel (12) such as by electrical circuit type detection.
