The aim of this work is to have a review of some products where halogens are used in the manufacturing process along with the safe disposal methods of its wastes. Different halogenated compounds are introduced. The theoretical results are validated by comparing them with experimental results. Results show that incineration is a safe disposal method of polychlorinated Biphenyls (PCBs). The incineration of PCBs in rotary kiln is shown based on theoretical and experimental studies. Where energy and material balances are applied to rotary kiln incineration to derive the theoretical model. The results from the theoretical model is validated against experimental results. The disposal method by incineration for other halogenated compounds is presented. Different models representing the combustion of other halogenated components are analyzed. It is shown that incineration is the safe disposal method for halogenated compounds at temperatures around 1200 K to avoid the formation of toxic gas emissions like furan and dioxin. The theoretical results are comparable with the experimental data of the incineration process.
