Main disposal technology for industrial wasites in Korea has been landfilling, however, this is encountering serious problems such as the lack of landfill sites and objections of residents. Incineration, therefore, has become a final solution for this dilema. Various kinds of air pollutants generation are possible because of the variety of types and compositions of wastes generated in industry. In this paper, air pollutants produced while incinerating hazardous industrial wastes are discussed and some control technologies are surveryed with the purpose of optimal design of incinerators and emission reduction. From this initial stage of incinerator utilization, low-emission type should be developed and applied and intensive research on pollutant generation due to waste incineration and advanced control technologies should be also performed.
