PET bottles recycling method has two kinds of chemical recycling and physical recovery. Chemical recycling method is to put the depolymerization of waste PET bottle in some reaction conditions generate useful chemicals, such as production low-grade gasoline fuel. Physical recycling method is to waste PET bottle after separation, crushing, washing and drying process of granulation method again. Physical recycling method basically has the following two kinds: one is to waste PET bottle cut piece, separated from the PET HDPE, aluminium, paper and glue, PET pieces again after washing, drying, granulation; 2 it is to waste PET bottles of PET bottle caps, a bottom, labels, magazines with mechanical methods, such as separation, after washing, crushing, granulation.
