Such landfills are usually located near large cities in consideration of their efficiency in transporting wastes. However, due to the expansion of cities and urban development plans, it is often necessary to actively use landfills where various wastes are randomly landfilled. Will occur.

In addition, as of January 1, 2003, the EPR (Extended Producer Responsibility) system has been expanded to mandate that all recyclable waste be recycled.

Therefore, randomly landfilled mixed waste or newly discarded mixed waste is inevitable to sort by type for its disposal, and the excavated waste is recycled with recyclable waste such as earth and sand and relatively heavy stone lumps and metals. Since waste materials that are difficult to recycle such as vinyl or wood chips are mixed together, there is a need for a waste sorting device for accurately sorting the entire waste by type.

Many research and development has been made for the waste sorting device to meet this need, and an example thereof will be briefly described with reference to FIG. 1, which is an accompanying drawing of the present invention.
