Zusammenfassung:	A wet-type waste plastic sorting method using difference in specific gravity is provided to crush different kinds of plastics into pieces two times and to discharge wastes together with the water according to each specific gravity by mixing the waste with the water by a stirring paddle. A wet-type waste plastic sorting method using difference in specific gravity comprises the steps of: sorting out plastic wastes according to the weight by using wind force; crushing the wastes that are not sorted according to the weight as the size and weight of the wastes are similar, in the mesh size of 10~20; arranging each plastic waste according to difference in specific gravity by mixing the crushed wastes with the water in a tank receiving the crushed waste, by using a stirring paddle; and discharging the wastes arranged in the water according to specific gravity, according to difference in specific gravity.
