PURPOSE: A method for preventing the re-use of a standard plastic garbage bag certified with a barcode is provided to delete a serial number recorded in a barcode from a serial number list of a central processing computer when a volume-rate disposal system bag certificated with a barcode is initially thrown. CONSTITUTION: If data read out from the barcode of a volume-rate disposal system bag are inputted to a computer(18), the inputted data are compared with use data inputted in advance. It is judged whether or not the serial number data read out from the barcode exist in the serial numbers recorded in the use data. If the serial number exits, the serial number recorded in the central computer is deleted and the use data are updated(22). A door of a slot is opened(26). |
