The increasing use of disposable plastics were causative of many kind of environmental problems in the world. Hence, researchers were tried to work for depolymerization of plastics, but the depolymerization methods could not easyly applicate to process system, because of too high process temperature and too long times of reaction. Therefore, we were attempt to depolymerization of PET through microwave system for more low-temperature and rapid times of reaction. The PET was glycolysised wiht ethylene glycol, and zinc acetate as reaction catalyst. Also, microwave was irradiated at 1000W by microwave reactor. Finally, glycolysis ratio of PET was verified by FT-IR, NMR and TGA, then yield of producted monomer were calculated by equation.
