The present invention relates to a waste management system and method using Radio Frequency IDentification (hereinafter referred to as "RFID"), and more particularly, by utilizing RFID, harmful effects such as infectious waste, designated waste or various industrial wastes can be obtained. To efficiently manage and supervise large special wastes, to ensure the speed and accuracy of business processes, and to increase the reliability of relevant administrative agencies and the industry by providing real-time tracking and information on wastes. In addition, the present invention relates to a waste management system and method using RFID that can simplify work processing.

Generally, various wastes that are harmful to human life should be treated safely through proper procedures. If the waste is improperly treated, it will not only cause secondary environmental pollution such as water quality, soil pollution and ecosystem destruction, Special care is required because it reaches the level of direct risk.

However, in the treatment and management of hazardous wastes to date, there are many cases where the actual waste treatment and flow of management information are inconsistent in time, delaying the collection of administrative information for waste management, and missing the collected data. Excessive manpower is required to verify this, such as the coming of rain, and so many inconveniences and unnecessary social expenses are being spent.

For example, the treatment process of infectious waste generated in a medical institution such as a hospital or research center will be described in more detail as follows.

Infectious wastes are generally referred to as infectious wastes generated in general hospitals, hospitals / hospitals, animal hospitals, research institutes, and the like.The treatment of such infectious wastes is collected by taking over the discharger and the waste discharged from the discharger. It is made by an interconnecting system of a collection carrier to transport, a waste processor that takes over waste from the collection carrier, and incinerates the waste, and a waste management center that is a computer processing body that supervises and manages the entire process from discharge of waste to disposal.

At this time, the waste management center has established and operated the waste legal processing system, which is an internet-based computer system, instead of the conventional off-line management method for proper management of infectious waste.

The management method based on the paper transfer document is described below with reference to FIG. 1.

First, in the case of a waste takeover, the procedure is as follows.

end. When discharging wastes to the carrier, the discharger shall fill in, confirm and hand over the six fields of the waste takeover form.

I. The carrier shall fill out and confirm the relevant fields of the six waste takeovers that were handed over at the time of taking over the waste, and return one waste transfer note (6) to the discharger, and the other five shall hand over to the processor when handing over the waste to the processor.

All. The processor fills out and confirms the corresponding fields of the five waste takeovers handed over at the time of taking over the waste, and returns one waste transfer note (5) to the carrier, saves one waste transfer note (4), and one waste takeover note (3) The waste shall be sent to the emitter within 3 days of receiving the waste from the carrier, and the remaining waste handover (1) and waste handover (2) shall be sent to the municipal or provincial governor or local government of the waste disposal facility within 7 days of the receipt of the waste from the carrier. It must be submitted to the head of the environmental agency.

la. The head of the municipal or provincial governor or the local environmental authority shall transmit the waste takeover letter (2) to the city, provincial governor or the head of the local environmental authority within seven days after the receipt of the waste takeover form pursuant to the provisions of the Multipurpose.

In addition, in the case of a simplified waste disposal certificate, the following procedure is required:

end. When discharging waste to the carrier, the discharger shall fill in, confirm, and take over the relevant section of the four separate waste slips.

I. The carrier shall fill out and confirm the relevant section of the four simple papers that have been handed over at the time of taking over the waste, and return one of the papers (6) to the discharger, and the remaining three papers should be handed over to the processor when handing over the wastes to the processor. do.

All. The processor fills out and confirms the corresponding fields of the three simple waste slips that were handed over when the waste was taken over, and returns one waste slip (5) to the carrier, saves one waste slip (4), and retains the remaining waste slip. (3) shall send it to the emitter within three days of receiving the waste from the carrier.

In addition, the Internet-based waste disposal treatment system, as shown in Figure 2, the discharger (emission company), the collection carrier (carrier), the waste processor (treatment company) are each connected to the Internet to discharge and take over the waste. It is to report to the administrative agency through the national administrative network by directly inputting the processing details and to compare, analyze and manage the voluntary reported information by the computer system.

However, the management method of the above-mentioned conventional paper handover is not only inconvenient because it needs to check the handbook (slips) by hand, but also makes handwriting, so the reliability of the information is low, and the waste that is disposed of illegally processed and neglected is high. There was an excessively high number of problems.

In addition, the application of the Internet-based waste disposal system improves the problems of excessive manpower, time, and cost compared to conventional paper transfer management methods, and provides the advantages of simplifying administrative tasks. The time taken for collection is delayed, which makes it difficult to dispose of the waste within an appropriate time period.

In addition, the currently applied Internet-based waste disposal treatment system requires that the emitter, the carrier, and the processor have to manually input information about the takeover and processing history of the waste, respectively, so that the user's turnover error or unit input or input Problems of input errors, such as exceeding the period, have been seriously raised, and accordingly, there was a problem in that post-checking was unnecessarily required and increased to confirm the error information as well as the system degradation.

Furthermore, since it is impossible to register the waste information on site in real time, the collection of administrative information of waste disposal for management supervision is still delayed due to the time discrepancy between the waste actually processed and the information entered on the Internet. It was difficult to check the processing status in real time, and problems such as intentional data manipulation due to the manual input of waste treatment information have been raised, and the public confidence in waste treatment and environmental policy has not been obtained.

The present invention has been made in view of the above problems, and the object thereof is to utilize RFID to process information through an information medium on which information about waste is recorded, thereby realizing the flow of waste and information. To ensure real-time understanding of the movement and disposal of wastes, and to obtain public confidence in the management and disposal of wastes in relevant administrative agencies and industries, and to avoid mutual distrust and input errors such as intentional data manipulation. The present invention provides a waste management system and method using RFID to block various diseases caused by manual information processing by blocking.

In addition, the present invention can greatly enhance the efficiency of the treatment and management of waste, RFID, which can simplify the processing of the work up to the management and supervision, including the discharge and transportation and treatment of waste. To provide a waste management system and method used.
