NOVELTY - The composting device comprises an enclosure (2) housing a cylindrical rotational wall (3) closed at its ends and comprising an opening (4) for introducing wastes and for evacuation of wastes. The cylindrical wall further comprises a rotor (5) carrying two fractionation walls (6) extending radially along its thickness, where the walls comprise holes sized for the passage of earthworms. The insertion opening is associated with a trough for introduction of wastes mounted on an axis to switch between an active position and a stowed position. The trough cooperates with the rotor.    USE - The composting device is useful in a kitchen for recycling wastes including organic materials, plastics and glass materials.    ADVANTAGE - The composting device is capable of easily and energy efficiently recycling the wastes without loss of weight and decomposition of wastes, and avoids the risk of mixing of fresh material with already composted materials.    DETAILED DESCRIPTION - The composting device comprises an enclosure (2) housing a cylindrical rotational wall (3) closed at its ends and comprising an opening (4) for introducing wastes and for evacuation of wastes. The cylindrical wall further comprises a rotor (5) carrying two fractionation walls (6) extending radially along its thickness, where the walls comprise holes sized for the passage of earthworms. The insertion opening is associated with a trough for introduction of wastes mounted on an axis to switch between an active position and a stowed position. The trough cooperates with the rotor through transmission so that the movement of the trough between the two active positions. The rotor is rotated by a motor unit. The base of the cylindrical wall provides evacuation of light under which a slide is positioned for collection of end product. The slide is equipped with a draining bottom for guiding exudates towards a flask. The cylindrical wall comprises a light equipped with an air grid and a filter for evacuating exudates towards the flask and to circulate the air. The slide comprises a ramp to allow the worms to rise in the volume defined by the cylindrical wall. The air grid is provided at the bottom of the device and at the top to form an air stream. The trough is housed in a housing located on the periphery of the cylindrical wall.    DESCRIPTION OF DRAWING(S) - The diagram shows a side sectional view of a composting device.
