A discarded industrial product recycling system capable of acquiring pertinent data required for processings of discarded industrial products such as discarders, reception dates, persons responsible for disposal, disposal dates and so forth for selecting proper disposal for each of the discarded industrial products while automatizing the article data acquisition to a possible maximum for enhancing the enhance disposal rate. An electronic tag (radio-frequency identifier tag) is attached to each of discarded industrial products to allow data required for the processing to be written and read by readers/writers. At a time point and a place where a discarded industrial product is received, basic data required for the processing of that article is written in the electronic tag. Pertinent processing route for each of the manufactured articles is decided by reading the data from the electronic tag while writing additional data in the tag as occasion requires. Properties of plastic material are measured, results of which are written in the electronic tag. Classification of component parts resulting from disassembling is carried out by affixing an electronic tag to each palette, reading the data from the electronic tag attached to the discarded industrial product and writing a code of assortment destination for the parts carried by the palette in the electronic tag affixed thereto on the basis of the data read from the electronic tag attached to the discarded industrial product.
