ABSTRACT:
A composting method and apparatus is shown and described. A volume of organic material to be composted is stacked on a surface to form a pile. A plurality of pipes are provided below the surface on which the pile is formed, each of the pipes having a plurality of holes that are aligned with corresponding holes in the surface. The pipes are connected to a manifold which in turn is coupled to a fan assembly, the fan assembly selectively creating positive and negative air flow through the pile. Air and moisture drawn from the pile flows through a conduit to a biofilter, cool air and fluid being added to the conduit upstream of the biofilter. The conduit passes through a greenhouse, such that heat radiated from the conduit is collected and used by the greenhouse. Moisture collected from the system may be treated and reused, for example, to irrigate the piles.
