Abstract
A compost crib is provided for the on-site disposal of animal carcasses accumulated during commercial operations, in which passive solar energy is utilized to assist in the decomposition process. Aerobic, thermophilic bacteria multiply in the sunlight, solar heat and heat of decomposition and convert nitrogenous material in carcasses and manure, as well as the carboniferous cellulose additive to the compost, to a bacterial biomass. The crib is simple in construction, having a frame with mesh walls to allow for adequate exposure to air. Access doors are provided for loading carcasses and for unloading recycled compost material for rotation back onto the compost mass. Solar panels are provided in the roof for the generation of solar heat and to provide sunlight to aid in bacterial photosynthesis.
Claims6
A method for composting animal carcasses, said method comprising depositing a layer of compost starter material within a crib enclosure, said enclosure being comprised of walls having mesh siding to expose an interior of said enclosure to oxygen from the air surrounding said crib, and a sloping floor for the drainage of water, said starter material comprising a nitrogen-rich component, placing a layer of carcasses on said layer of compost starter material, completely covering said layer of carcasses with a compost medium, said medium being comprised of sawdust and animal waste, placing subsequent alternating layers of said carcasses and said compost medium to fill said crib enclosure, exposing the contents of said filled crib to solar heat and direct light generated by solar glazing panels provided on said crib and introducing air to an interior of said contents to facilitate aerobic decomposition, air being introduced into said interior of said contents by inserting and extracting an aerating tool whereby a furrow through which air passes is created, said tool comprising an elongated rod, said contents further being rotatively mixed by extracting a bottom portion of said crib contents through a door at a bottom of said crib and inserting said bottom portion onto a top of said crib contents, whereby said contents are effectively aerated, whereby said carcasses are decomposed.
A crib for composting animal carcasses, said crib comprising a framework for receiving carcasses defining four walls, a top cover and a floor, a rear wall of said framework being greater in height than a front wall of said framework whereby a top plane of said framework slopes downward from a rear side of said crib to a front side of said crib, said top cover being connected to a top of said rear wall in hinged relationship whereby said top cover is moveable between open and closed positions for loading material into said crib, said floor having a slope for the drainage of water, said walls having mesh siding whereby air may pass freely therethrough, said top cover having solar glazing panels whereby solar heat and light are transmitted directly to an interior of said crib, said framework being provided with a plurality of access doors, at least one of said access doors being placed at a top portion of said rear wall whereby material may be placed within said crib, and at least one other of said access doors being placed at a bottom portion of one of said walls whereby material may be removed from said crib.
A crib for composting animal carcasses, said crib comprising a framework for receiving carcasses defining four walls, a top cover and a floor, a rear wall of said framework being greater in height than a front wall of said framework whereby a top plane of said framework slopes downward from a rear side of said crib to a front side of said crib, said top cover being connected to a top of said rear wall in hinged relationship whereby said top cover is moveable between open and closed positions for loading material into said crib, said floor having a slope for the drainage of water, said walls having mesh siding whereby air may pass freely therethrough, said top cover having solar glazing panels whereby solar heat and light are transmitted directly to an interior of said crib, said framework being provided with a plurality of access doors, at least one of said access doors being placed at a top portion of said rear wall whereby material may be placed within said crib, and at least one other of said access doors being placed at a bottom portion of one of said walls whereby material may be removed from said crib, means being provided for aerating said material in said crib, said means comprising a tool having a handle at one end of an elongated rod and retractable lugs at another end, said lugs having means to be in a retracted, co-directional alignment with said rod when said rod is inserted into said material in said crib and in an extended, perpendicular alignment with said rod when extracted from said material, said tool being inserted into said material from a top opening of said crib when said top cover is in said open position, whereby said material is turned by said lugs when said tool is extracted.
