PROBLEM TO BE SOLVED: To provide a system for efficiently sorting reusable corrugated boards for recycling.;SOLUTION: Each corrugated board 9 used in the system has stuck thereto a resonant tag whose resonant frequency can be changed. A sorting system is provided with conveyors 200 and 201 and determines the number of uses of each corrugated board 9 by radiating a radio wave including a predetermined frequency from an antenna of a detection gate 21, and identifying the wave reflected from the resonant tag. The corrugated boards 9 that have been used a predetermined number of times or more are sorted out by a sorting arm 22 and delivered to the conveyor 201. The corrugated boards 9 on the conveyor 201 are manually sorted and those which are not reusable are disposed of. Reusable ones are brought back to the conveyor 200 and used again along with the corrugated boards 9 that were used less than the predetermined number of times.;COPYRIGHT: (C)2003,JPO
