PROBLEM TO BE SOLVED: To solve the problem that refuse bags and trash need to be separated and removed to convert raw refuse into compost but are hard to mechanically separate due to their variety such as material/shape being too many, that the separation and removal of the refuse bags from the raw refuse have a difficulty in separation from the raw refuse because the refuse bags got caught in a machine or smashed into pieces, and that the method employed for stripping the refuse bags one by one by human hands causes a strong bad smell to be given off from the raw refuse, an injury due to a solid projection to occur and expenses to increase. SOLUTION: While rotating the plural disc type cutting blades placed side by side, the raw refuse together with the bag, while transferring it on a transfer conveyer, is cut into thin round slices. A hard solid body hits the circular cutting blades in plural lines and the blades start idling, the transfer speed of the bagged raw refuse becomes slow, which is detected and the transfer conveyer and the plural rotating disc cutting machine is stopped, and the hard solid body is checked for and removed. The refuse bag cut into thin round slices and mixed in the raw refuse is subjected as it is to fermentation treatment and changed into compost, then removed using a screen selection unit.
