Abstract
This paper describes de novo synthesis potential of gasification-melting system differ form that of conventional incinerator because the composition of fly ash is largely different. The fly ash from gasification-melting plant contained very little amount of unburned carbon which could serve as a carbon source for dioxins formation. In contrast, volatile heavy metals such as Pb, Zn and Cu in fly ash which could serve as catalyst were enriched. In this study, experiments were performed using various fly ashes from gasification-melting plants in order to clarify the effect of unburned carbon and metal components in fly ash on de novo synthesis.
