Abstract
RFID (Radio Frequency Identification, IC tag) technology has been put to practical use in many areas. It is expected that RFID will also be used in designing or developing new recycling systems or in managing waste materials. We suggest that the technology using IC tags, which are able to store a relatively great amount of data related to the specification of the materials, can be used in various recovery or separation processes and be used at the surface contamination condition. Such a process can be effective since it not dependent of the physical properties of the materials to be processed. At first, the use of a microwave type IC tag, mounted on artificial parts to be separation, was investigated as a function of the speed and distance from the IC tag data reader. Next, if IC tags are utilized for the parts reuse and store of automobiles in order to increase the material recycling rate. Moreover, the environmental burden for automobile recycling has also been discussed.
