A number of topical papers were presented which represent a cross section of a part of the incineration technology in use and under regulatory examination during this period. The proceedings cover a conference which was co-supported by EPA and the American Society of Mechanical Engineers which was organized as a cooperative agreement grant effort from the EPA in the spirit of professional interest and public discussion of the thermal disposal technologies and their regulation.
