NOVELTY - The compostor comprises adjacently-aligned compartments comprising a rear wall, a front wall, an external lateral wall, a lid and a partition wall, and support elements disposed in middle of the compartments. The rear, front and lateral walls and the partition wall are mounted on a frame and disposed on a base. Each wall is divided into two panels including an upper panel (16) and a lower panel (18). The upper panel is adapted to pivot between a closed position and an open position. The partition wall comprises a fixed lower part (10) and a movable upper part (12).    USE - The compostor is useful for recycling organic waste (claimed).    ADVANTAGE - The compostor ensures rapid, economic and easy recycling of large volume of organic waste in an environmental friendly manner.    DETAILED DESCRIPTION - The compostor comprises adjacently-aligned compartments comprising a rear wall, a front wall, an external lateral wall, a lid and a partition wall, and support elements disposed in middle of the compartments. The rear, front and lateral walls and the partition wall are mounted on a frame and disposed on a base. Each wall is divided into two panels including an upper panel (16) and a lower panel (18). The upper panel is adapted to pivot between a closed position and an open position. The partition wall comprises a fixed lower part (10) and an upper part (12) movable between the closed position and the open position for transferring a fraction of organic waste present in the first compartment towards the adjacent compartment. The upper panel has a height, which is lower than or equal to a height of the lower panel. The lower panel is attached, in rotation, with a vertical upright for allowing opening of the wall when the upper wall is folded back against the lower panel. The frame comprises a removable upper section whose height corresponds to a height of the lower and upper panels. The compartments are divided into upper and lower compartments, and comprise a perforated base for ventilating organic waste. An INDEPENDENT CLAIM is included for a method for recycling an organic waste.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a compostor.
