<p>PROBLEM TO BE SOLVED: To provide a new classifying treatment system for mixed waste, capable of efficiently classifying mixed waste in which a variety of waste materials are mixed, and improving the treatment and recycling of the mixed waste. SOLUTION: Mixed waste is separated into a plurality of sub-classes by classifying the mixed waste into a plurality of classes by a first classification means 12 and, furthermore, air-separating each class by second classification means 14a, 14b, 14c. Thereafter, the resultant wastes of the same sub-class after the air separation are collected together again to be classified with a third classification means 18 by using the specific gravity of water. In this way, the first classification means 12 such as sieves to carry out the classification based on the size, the second classification means 14a, 14b, 14c as an air separation means, and the third classification means 18 as a gravity separation means are combined in a specified style, realizing a new classifying treatment system which can classify mixed waste with high treatment efficiency and high accuracy.</p> |
