Applications for the destruction of hazardous and waste materials such as halogenated hydrocarbons by reactive thermal plasmas are reviewed. For halogenated hydrocarbon decomposition, key technologies are the stable generation of DC steam plasmas and the off-gas treatment after the decomposition of halogenated hydrocarbon. Therefore, DC 100%-steam plasma characteristics were investigated for the application of halogenated hydrocarbon decomposition. The described steam plasma system is a portable light-weight plasma generation system that does not require any gas supply. The system has high energy-efficiency since cooling water is not needed. In addition, a dry process was developed for halogenated hydrocarbon decomposition and simultaneously adsorbing fluorine and bromine with solid alkaline reactants.
