Abstract
A rotary drum-type composting apparatus is disclosed, in which the drum is of circular cross section and is supported for rotation about a horizontal axis by means of external support wheels. An access opening is provided in the sidewall of the drum for loading of compostable material, and a removable flexible, waterproof cover is applied over perforated sidewalls of the drum, enabling the interior of the drum to be closed off so that the composting processes can occur. The drum is mounted as close to the ground or supporting surface as practicable, to facilitate manual loading of compostable materials. A clearing bar is installed on the outer surface of the drum, preferably on a removable door panel provided for closing the access opening. The clearing bar operates between the outer surface of the drum and the support wheels and their mounting shafts. During sifting operations, following completion of composting, the clearing bar sweeps away a clearance space below the drum, for efficient outsifting of the composted material from the drum.
