PCDF/D emission from waste utilization in cement kilns

摘要

Thermal waste utilisation is strongly debated environmental issue, especially siting a new incineration plant. An alternative possibility is to utilise existing industrial installations for waste incineration, what is strongly support by directives of European Community. This paper gathers the current state of knowledge on hazardous emissions such as PCDFs and PCDDs from waste incineration in cement kilns. Although, condition of clinker production are hardly preferable for PCDF/Ds. formation, some mechanisms allowing PCDF/D synthesis are discussed as well as mechanisms inhibiting formation of PCDF/Ds.
