Experimental and theoretical studies are presented from a laboratory scale thermal destruction facility on the destruction behavior of surrogate plastic and non-plastic solid wastes. The non-plastic waste was cellulosic while the plastic waste contained compounds such as polyethylene, polyvinyl chloride, polystyrene, polypropylene, nylon, rubber and polyurethane or any of their desired mixtures. A series of combustion tests were performed with samples containing varying composition of plastic and non-plastic. Experimental results are presented on combustion parameters (CO, excess air, residence time) and toxic emissions (dioxin, furan, metals). Equilibrium thermochemical calculations are presented on the thermal destruction behavior of samples under conditions of pyrolysis, combustion, and pyrolysis followed by combustion. Special interest is on the effect of waste properties and input operational parameters on chemistry and product composition. STANJAN and SOLGASMIX computer codes were used in the chemical equilibrium study. Analysis and interpretation of the data reveal the effect of waste feed composition on combustion parameters and dioxin, furan and metals emission. Equilibrium calculation results are used to describe the experimentally observed trends for the thermal destruction behavior of the wastes. The results show significant influence of plastic on combustion characteristics, and dioxin, furan and metals emission.
