The present invention is poly relates to a decomposition process and apparatus of polyester waste, raw material of polyethylene terephthalate (polyethyleneterephthalate, PET) polyester raw materials of dimethyl terephthalate (dimethyl terephthalate, DMT) and ethylene glycol (ethylene glycol, EG) It will screen a playback process and apparatus for. Molten groups are separated Indeed, a number of separate melting to be operated in a continuous manner and was provided with a transfer syntax consisting of a motorized or manual screw and check valve for transferring indeed gradually separated molten be recovered it is easy to evaporate from the melting process, EG be the final reaction product of EG recovering capacitor and melting period in the first equipped with a continuous edible ridge containing in a possible high pressure pump into the reactor, the overall process time compared to the batch system, the reaction time, the product in the first reactor in a molten group to a minimized energy consumption by reducing the reaction time to increase the overall reaction rate because of the melt to conserve energy lost stopping the first reactor group to be introduced characterized in that so that the economical operation.
