NOVELTY - A composting apparatus comprising an air blower having an air intake and an air output, suction and discharge manifolds connected with the air intake and the air output of the blower, pile manifolds positioned away from the blower and a damper connected between each pile manifold, and the suction and discharge manifolds, is new.    USE - For controlling airflow to and from aerated static composting piles.    ADVANTAGE - The low cost and portable apparatus provides accelerated aerated static pile composting while controlling odors which are generated in the composting process. It allows each aerated static pile to be placed under positive or negative air pressure at the operator's direction while utilizing single non-reversible system wide air blower. It does not need pavement or permanent installation thus reducing installation costs and enhances portability.    DETAILED DESCRIPTION - A composting apparatus comprises an air blower having an air intake and an air output, a suction manifold connected with the air intake of the blower, a discharge manifold connected with the air output of the blower, pile manifolds associated with compost piles positioned away from the blower, and a damper connected between each pile manifold, and the suction and discharge manifolds, where the damper provides connection between the pile manifolds and the suction or the discharge manifolds, is new.    INDEPENDENT CLAIMS are also included for the following:    (1) an aerated static pile composting system; and    (2) a method for aerated static composting pile comprising placing a volume of organic material in piles, providing a single air blower having an intake creating negative air pressure and an output creating positive air pressure, and connecting each pile with blower intake or blower output.    DESCRIPTION OF DRAWING(S) - The figure is a perspective view of a portable and reconfigurable composting system.
