Abstract

Vent structures are provided on the upper and lower sides, and lid of an organic waste cart so that wet biomass deposited in the cart is dried by convective air currents passing through the cart. The lid vent is hooded to prevent moisture from passing into the biomass. A perforated false bottom within the cart elevates the biomass above the lower vents to assure that drying air can circulated throughout the biomass.

Claims

1. A waste cart that enables the drying of moist waste therein including:

a hollow body having;

a lower portion;

an upper portion defining;

an opening for loading and unloading waste from said hollow body; and

at least one vent hole in said lower portion; and

a lid for closing said opening for loading and unloading waste from hollow body, said lid including;

at least one lid vent there through, including;

a vent hole in said lid; and

a hood covering said lid vent hole, including;

a generally horizontal hood portion;

a sidewardly facing opening in said hood covered with respect to falling rain by said hood portion;

a perforated plate covering said sidewardly facing opening; and

a reinforcing groove centrally located in said hood at a right angle to said perforated plate, whereby air can convect through said at least one vent hole in said lower portion, through any waste contained in the hollow body and out said lid vent carrying moisture therewith.

2. A waste cart that enables the drying of moist waste therein including:

a hollow body having;

a lower portion;

an upper portion defining;

an opening for loading and unloading waste from said hollow body; and

at least one vent hole in said lower portion; and

a lid for closing said opening for loading and unloading waste from hollow body, said lid including;

at least one lid vent there through including;

a vent hole in said lid; and

a hood positioned over said lid vent hole to shield said vent hole from down falling moisture, whereby air can convect through said at least one vent hole in said lower portion, through any waste contained in the hollow body and out said lid vent carrying moisture therewith, wherein said hood covering said lid vent hole includes;

an abutment surface for contacting said lid about said lid vent hole;

at least one L shaped retainer member to hold said hood to said abutment surface; and

at least one catch member opposite said at least one L shaped retainer member to releasably retain said hood to said lid.

3. The waste cart as defined in claim 2 wherein said hood covering said lid vent hole further includes:

a generally horizontal hood portion;

a sidewardly facing opening in said hood; and

a perforated plate positioned in said sidewardly facing opening.

4. A waste cart that enables the drying of moist waste therein including:

a hollow body having;

a lower portion;

an upper portion defining;

an opening for loading and unloading waste from said hollow body; and

at least one vent hole in said lower portion; and

a lid for closing said opening for loading and unloading waste from hollow body, said lid including;

at least one lid vent there through including;

a vent hole in said lid;

a hood positioned over said lid vent hole to shield said vent hole from down falling moisture, whereby air can convect through said at least one vent hole in said lower portion, through any waste contained in the hollow body and out said lid vent carrying moisture therewith;

a perforated false bottom positioned in said hollow body above said at least one vent hole in said lower portion to allow air circulation under waste retained above said false bottom, wherein said lid vent hole including;

an abutment surface for contacting said lid about said lid vent hole;

at least one L shaped retainer member to hole said hood to said abutment surface;

at least one catch member opposite said at least one L shaped retainer member to releasably retain said hood to said lid;

a generally horizontal hood portion;

a sidewardly facing opening in said hood covered with respect to falling rain by said hood portion; and

a perforated plate located in said sidewardly facing opening at about 45°

to said generally horizontal hood portion.

5. A waste cart that dries moist waste therein including:

a hollow body having;

a lower portion;

an upper portion defining;

an opening for loading and unloading waste from said hollow body;

at least one vent hole in said lower portion; and

at least one vent hole in said upper portion; and

a lid for closing said opening for loading and unloading waste from hollow body, said lid including;

at least one lid vent there through, whereby air can convect through said at least one vent hole in said lower portion, through waste contained in the hollow body and out said lid vent carrying moisture therewith, whereby moisture does not accumulate under said lid, said at least one lid vent including;

a vent hole in said lid; and

a hood covering said lid vent hole including;

an abutment surface for contacting said lid about said lid vent hole;

at least one L shaped retainer member to hold said hood to said abutment surface; and

at least one catch member opposite said at least one L shaped retainer member to releasably retain said hood to said lid.

6. The waste cart as defined in claim 5 wherein said lid is hingedly connected to said hollow body.

7. The waste cart as defined in claim 5 further including:

a least one vent hole in said upper portion of said hollow body; and

a plurality of perforated vent covers positioned over said at least one vent hole in said lower portion of said hollow body and said at least one vent hole in said upper portion of said hollow body.
