NOVELTY - A composting apparatus (100) includes a housing (60); composting drawers (10) stacked within the housing and each has bottom region and apertures; and receiving structures (30a-b) in the housing. The receiving structures are disposed under the composting drawers to receive composted material.    USE - The composting apparatus is used in schools, grocery stores, day care centers, restaurants, zoo, jails, military bases, hospitals, cafeterias, farm, or multi-family housing units for converting organic waste, e.g. pre and post consumer food waste, low grade paper waste, food contaminated paper waste, agricultural waste including manure and crop residuals, municipal biosolids, or industrial organic sludge, into useable product, such as natural fertilizer in form of humus.    ADVANTAGE - The apparatus can process all organic waste produced by the facility into high quality organic product while occupying minimal space at the facility. It has a pulling and pushing action that agitate the composted material in a much less labor intensive that the conventional apparatus. The agitation process is simple and does not require the use of complicated machinery. It has many processing zones thus resulting in a greater compost production rate without increasing the occupied space. It can be used as a practical way for disposing the organic waste while also being educational tool, i.e. by using the tool to learn environmental sound waste conversion processes and biology.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (a) a composting system comprising a shipping container and the composting apparatus inside the container; and    (b) using the composting apparatus by placing compostable material and composting microorganisms into each drawer, composting the compostable material within the drawers, agitating the composted material through the apertures, and passing the agitated composted material through the apertures of the drawers.    DESCRIPTION OF DRAWING(S) - The figure shows a perspective view of composting apparatus.
