ABSTRACT:
A garden composter for decomposing garden waste in which the composter has a longitudinally extending cylindrical outer drum which is mounted to a support frame. Tumbling means are provided for coupling the drum to the support frame for rotation of the drum relative to the support frame about an axis of rotation of the drum. The drum has at least one load opening formed in a cylindrical wall portion for receiving organic waste into an outer chamber and a closure cap for selectively closing the load opening. An inner drum is fixed to the interior of the outer drum for rotation with the outer drum and has waste inlet means in communication with the outer chamber for receiving decomposing organic waste into an inner chamber before being discharged through a waste outlet. In this way, the garden composter can receive organic waste through the load opening for decomposition in the chambers and the waste can be aged in the inner chamber to prolong its residence time before being discharged from the composter.
