Abstract

The compostable waste processing apparatus includes a pulverizing device and a shredding device in separate compartments within a housing. The pulverizing device and the shredding device may be driven by at least one electronic motor. The electronic motor may be powered by one or more batteries that are charged by a photovoltaic panel of the housing. The compostable waste processing apparatus has a simple and efficient structure to facilitate use by a wide range of end-users, including households.

First claim

I claim:

1. A compostable waste processing apparatus, comprising:
a first housing, including:
a first compartment, the first compartment including a pulverizing device, and
a second compartment laterally adjacent to the first compartment and separated from the first compartment by a divider wall, the second compartment including a shredding device; wherein said pulverizing device and said shredding device are distinct and different from each other;

a second housing adjacent to the first housing, the second housing including at least one motor adapted to drive the pulverizing device and the shredding device, and at least one battery for powering the motor;
a door movably affixed to a top portion of the first housing, the door including a photovoltaic panel, the photovoltaic panel being adapted to charge the at least one battery;
a first collection channel below the pulverizing device in the first compartment;
a second collection channel below the shredding device in the second compartment;
a first collection drawer in communication with the first collection channel; and
a second collection drawer in communication with the second collection channel;
wherein the first collection channel is configured to gather and direct waste processed by the pulverizing device to the first collection drawer and the second collection channel is configured to gather and direct waste processed by the shredding device to the second collection drawer.

2. The compostable waste processing apparatus according to claim 1 , wherein the first collection channel and the second collection channel each include an ejection device to direct processed waste to respective ones of the first and second collection drawers, the ejection device being selected from the group consisting of a fan, a blower, and a screw.

3. The compostable waste processing apparatus according to claim 1 , wherein the first housing includes one or more walls having fiberglass insulation.

4. The compostable waste processing apparatus according to claim 1 , wherein the pulverizing device includes two horizontally aligned rotary shafts, each of the shafts extending through a series of pulverizing elements, the pulverizing elements being configured to rotate around a respective one of the shafts for pulverizing waste disposed in the first compartment.

5. The compostable waste processing apparatus according to claim 1 , wherein the shredding device includes two horizontally aligned rotary shafts, each of the shafts extending through a series of shredding elements, each of the shredding elements being configured to rotate around a respective one of the shafts for shredding waste disposed in the second compartment.

6. The compostable waste processing apparatus according to claim 1 , wherein at least an exterior portion of the compostable waste processing apparatus includes a reflective insulating material.

7. The compostable waste processing apparatus according to claim 6 , wherein the reflective insulating material includes a polyethylene bubbled film sandwiched between two aluminum sheets.

8. The compostable waste processing apparatus according claim 1 , further comprising a ventilation motor in the second housing, the ventilation motor configured to circulate air throughout the first housing.
