Rotatable aerating composter

Abstract

The present invention is a device and method for efficient composting of organic matter using a low-cost composting structure and high efficiency methods. A composting container incorporates rigid insulated panels to form an insulated composting container of a generally cylindrical shape with polygonal cross-section. The insulated panels provide high thermal efficiency at low cost to help maintain composting temperatures. A rigid frame supports the panels and allows the container to be rotated. An internal manifold or plenum supplies air while the container is stationary or rotating. Rotation in various embodiments is effected by motor driven rollers bearing on external hoops integrated to the container support frame. In preferred methods, the container is rotated at rates slower than one revolution per minute as air is introduced.
