NOVELTY - The apparatus (1) has box (10a) which is provided with side plate (12) standingly arranged so that circumference is enclosed. A bottom portion (13a) is comprised considering mesh-like material (14) of 10-35 mm of mesh as a main element. An upper cover (11) is mounted on the uppermost box, so that soil and an organic refuse are thrown into the uppermost box, and composting is accommodated in the box of a lowermost stage. The bottom portion is equipped with bottom side board (15a) suspended down from the lower end of side plate. The mesh-like material is provided in the bottom side board.    USE - Garbage processing apparatus for digesting organic refuse used as feed of earthworm.    ADVANTAGE - The movement of the earthworm between boxes is made easily. The organic refuse is composted efficiently. The classification of compost and earthworm is made unnecessary while taking out the composted contained-object. The production of a maggot is prevented. The escape of earthworm is prevented.    DETAILED DESCRIPTION - A moth paper is covered on organic refuse thrown into the uppermost box. A lateral plate is provided to cover the side surface of the box. A lighting door is opened and closed in the lower portion. An outer cover is provided to cover the upper surface of the lateral plate. The box is floated and mounted in base (19) from an installation place. An outer case is provided with reflecting plate inside the box. The light taken in from the lighting door is reflected by reflecting plate, and is irradiated to the bottom portion of the accumulated box. The bottom side board is fit to the inner surface upper end of the side plate of the box mounted in the lower stage. A peripheral board is provided with bottom portion that is extended towards the inner side of the side plate from the lower end of the side plate. An opening portion is provided in the center. The bottom side board is suspended down from the edge of the opening portion. The mesh-like material is provided to cover the opening portion. The side plate is provided with water/air flow hole (18a,18b) in the upper-end vicinity. An INDEPENDENT CLAIM is included for garbage processing method involves mounting contained-object of box in the lower stage, so that the movement of the earthworm between the boxes is enabled. The box of the lowermost stage is removed from the accumulated box, while composting of the contained-object of the box of the lowermost stage is completed. The cycle that mounts the empty box which remained is repeated when the box currently mounted in the upper stage is box of a new lowermost stage.
