ABSTRACT:
An improved composter has a unique architecture that adaptively regulates the air and moisture content of an interior chamber to facilitate efficient decaying of organic matter contained therein. In an illustrative embodiment, the improved composter comprises spaced upper and lower cones disposed within a cylindrical barrel to form the chamber. A plurality of apertures are disposed along the surfaces of the barrel and cones, and are arranged such that a plurality of the apertures of the cones are in registration with the apertures of the barrel. The upper cone descends upon the organic matter as its volume decreases during its decomposition, while the apertures control the amounts of air and moisture penetrating the chamber to maintain a state of equilibrium that is conducive to rapid and efficient composting.
