| Abstract: | A vast amount of waste plastics is now a significant environmental problem. Thus various treatment or decomposition processes for waste plastics are under development. In this paper, chemical recycling processes of waste plastics using supercritical water as reaction solvents were described. A general overview was done on supercritical water property and the process of pyrolysis and partial oxidation in which waste plastics (PE, PP, PS) were converted to monomers, oils, and gases. The results show that the waste plastics are decomposed in high speed using supercritical water, and higher conversion is obtained than those obtained by pyrolysis. Finally, the research should be enhanced in order to solve the problems of resource shortage and environmental pollution. |
