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.

Abstract: An apparatus and process for the efficient vermicomposting of organic containing wastes. A continuous thin layer of biomass is formed in which worms are established and encouraged to compost and migrate. The thinness of the biomass layer increases uniformity and allows for a higher rate of worm activity. By moving the biomass upon a conveying surface a continuous open system is created. New matter is introduced, digested and withdrawn while maintaining the active worms within a portion of the biomass. Spatial efficiency is provided by creating multiple beds in a stacked configuration.

Abstract: A drill jig assembly for drilling holes in an extruded aluminum shape; including a metal channel base, a plastic plate having upright hole patterns and a plurality of position pins located in the holes for positioning the shape widthwise for drilling, and an extension arm for positioning a stop pin against which the shape can be positioned lengthwise for drilling. This jig is used principally for drilling assembly holes in an aluminum window vertical frame piece to correspond to a pair of spaced sprues in the horizontal frame piece and different positioning pins are required for different shapes and different hole patterns in the plate likewise are required to accommodate for different shapes.
