NOVELTY - Composter (1) comprises a composting body with a vertical continuous central core ventilation (2), where a ventilating body is made in a flexible manner, and immediately ventilation openings increase radially from the bottom to the upper edge of the composter, and the increased supply of oxygen from the bottom to the upper edge of the composter accelerates decomposition process, prevents anaerobic decomposition and the associated odors. An air circulating path through a composting material (4) is present from outside (5) to inside (6) via the central core ventilation.    USE - The composter is useful for composting garden- and kitchen waste.    ADVANTAGE - The composter allows ventilation even in central areas, and running of air and exhaust air along the entire composting material, and thus it restricts access of oxygen to the microorganisms, prevents unpleasant odors, and improves composting conditions.    DETAILED DESCRIPTION - Composter (1) comprises a composting body with a vertical continuous central core ventilation (2), where a ventilating body is made in a flexible manner, and immediately ventilation openings increase radially from the bottom to the upper edge of the composter, where the increased supply of oxygen from the bottom to the upper edge of the composter accelerates decomposition process, prevents anaerobic decomposition and the associated odors. An air circulating path through a composting material (4) is present from outside (5) to inside (6) via the central core ventilation, where the living conditions for organisms and bacteria are favored with the increased supply of oxygen. The air circulating path supports the ventilation duct from the bottom to the upper boundary edge of the composter. A central core ventilation channel is inserted for stabilizing into the soil.    DESCRIPTION OF DRAWING(S) - The figures 1 and 2 show a schematic representation of the composter, and the air circulating path, respectively.
