Abstract: A compostable scoop for use with a powder-like substance includes a first form including a cup shaped element configured for scooping a powder-like material, the cup-shaped element coupled to a handle element configured for holding by hand, the handle element having a channel on its top and a ridge on its bottom for structural rigidity, the first form composed of a compostable composition substantially including pulp, a second form congruent with the first form, wherein the second form is shaped and sized to be pressed on top of, and together with, the first form, the second form composed of the compostable composition substantially including pulp, and an adhesive layer deposited between the first form and the second form, wherein the adhesive layer holds the first and second forms securely together.

Abstract: In a composter having a horizontally elongated rotating drum, material is fed into the drum through an opening in a stationary end plate having an annular marginal area which overlaps, in sealing relationship, an annular intake end wall of the drum. Material passes through a central opening in an annular exit end wall of the drum, and falls by gravity onto a cylindrical screen which is fixed to, and rotates with, the exit end wall. The annular end walls are in axial register with, and surrounded by, external trunnions on the drum which ride on pairs of supporting rollers. Frusto-conical rings are welded to the end walls, and to the inside of the drum at locations opposite the edges of the trunnion rings to reduce metal fatigue. The exit end rollers allow for axial expansion of the drum. The interior wall the drum is lined with a rubber.

Abstract: A composting apparatus including an electric motor driven drum. The drum is provided with spaced fins on the inner surface and a supporting shaft that can include air holes to provide air within the confines of the drum. In this instance, tubes with holes are secured inside the drum and communicate with a source of air so that air passes into the tubes, and thus into the pile of composting material. The drum is provided with a sliding door that closes an opening in the drum. The door is secured at its ends for movement within a grooved mount attached onto a surface of the drum. The door is moved along a surface of the drum to open the door. The door can be held in position with a small opening or to a full open position, thus opening the entire opening in the surface of the drum.
