Because the 1984 Amendments to the Solid Waste Act require that the wastes listed under the Resource Conservation and Recovery Act (RCRA) be passed through an analysis to assess the feasibility of banning from further land disposal, more incineration is expected to be used for disposing of either the banned wastes directly or the residues of various treatment processes. Incineration of hazardous wastes, municipal wastes and industrial sludges all produce some extent of trace metals. The paper provides a preliminary model concept for analyzing metal partitioning during incineration. The paper concludes that a model for predicting metal partitioning phenomenon is feasible and will save cost in conducting metal emission testing in the field.
