As the land disposal of untreated hazardous wastes has continued to fall into disfavor in North America, increasing attention is being given to alternative hazardous waste treatment and disposal technologies. This increased attention and the public and private support resulting from such attention have resulted in the development over the past several years of many very innovative processes. This paper, which is based upon the survey of innovative thermal processes carried out by the staff of the U.S. Environmental Protection Agency's Hazardous Waste Engineering Research Laboratory in Cincinnati, Ohio, discusses six innovative processes currently being discussed in governmental, academic, and industrial circles in the United States and Canada. They are: High Temperature Electric Reactor, Wet Oxidation Process, Plasma Arc Technology, Supercritical Water, Molten Glass Incineration, and Molten Salt Reactor.
