  • Publication number: 20130263786
    Abstract: A composting apparatus and method utilizing a vessel for receiving organic material which is rotatably supported. In a preferred embodiment, the vessel has a two corrugated conduits of different diameters and the one of smaller diameter is axially aligned inside the larger conduit to move and agitate the material in two different lateral directions. The worm vermicompositing takes place in the inside of the smaller diameter conduit, dropped into the outlet larger conduit where it is dried and collected. In another embodiment, the vessel is fabricated from secured end-to-end at their top ends. The vessel is rotated by an electric motor with a gear reduction drive sprocket engaging a peripheral track on the exterior of the larger diameter conduit. Water can be added during the vermicompositing to make and collect worm tea.
