Abstract
A domestic composter of molded plastic has an upwardly tapered body comprising an upper and a lower half, with tongue and socket connectors such that the two halves may be firmly assembled together or separated without the use of tools. The upper half fits readily within the lower half, permitting transportation of the composter within a standard size automobile. The tapered construction enables multiples of the respective body portions to be nested, for economical bulk transportation. An access door is provided, having securing lugs that may be padlocked, and the removable lid of the composter may be rotated into a selectively variable position that precludes removal and affords ventilation control. The lid may be readily removed, or may be electively opened to a partial-access position for one-handed depositing of waste therein. A comprehensive vent system allows controlled cooling and ventilation while precluding access even to small animals such as mice. Screw-down earth anchors may be used to anchor the composter to the ground, or over a plain base plate.
