Abstract
A portable and reconfigurable composting apparatus for controlling the airflow to and from a plurality of aerated static composting piles. The composting apparatus includes an air blower having an air intake and an air output. A suction manifold is attached in fluid communication with the air intake of the blower. A discharge manifold is attached in fluid communication with the air output of the blower. A plurality of pile manifolds are connected to the suction manifold and the discharge manifold by a manifold crossover. The manifold crossover includes a pair of dampers which allow the composting apparatus operator to independently select positive or negative air pressure for application to each pile manifold. Each pile manifold is operatively associated with an aerated static compost pile, by means of a series of flexible air lances attached in fluid communication with a pile manifold.
