A disposable container insert tray may be composed of rows separating conical shaped depressions that are used to channel the liquid to all levels of the container so that liquids can be exposed to the maximum volume of the non-biodegradable substance for total encapsulation. In embodiments, the top of the liquid disposal container may be covered with an open weave fabric material that acts as a diffuser whereby the liquid materials are spread more equally throughout the confines of the container and on to the surface of the tray insert. ## Claims ### Claim 1 A liquid disposal tool for the collection and disposal of liquids comprising: a container with a bottom portion and a set of walls; a peat moss absorbent resting on said bottom portion within said walls, said absorbent configured to collect said liquid; an insert tray overlaying said absorbent, said insert tray contoured with a series of rows separating a set of conical depressions protruding downward into said absorbent layer, and a series of flat top pedestals in the series of rows, said series of flat top pedestals extending upward with respect to said bottom portion of said container, and a series of gaps that separate the flat top pedestals; a diffuser sheet overlaying said insert tray; and wherein said flat top pedestals are wider than said gaps, where said gaps serve as channels to distribute the liquid or hydrocarbon materials, and said flat top pedestals serve as supports and as attachment points for said diffuser sheet. ### Claim 2 (depends on 1) The liquid disposal tool of claim 1 wherein said container is made of materials comprising paper, cardboard, plastic, oriented strand board (OSB), sugar cane, and composite material containing any of the aforementioned. ### Claim 3 (depends on 1) The liquid disposal tool of claim 1 wherein said container is made of a recycled material. ### Claim 4 (depends on 1) The liquid disposal tool of claim 1 wherein said top portion of said walls further comprise a perimeter shelf with an upper lip. ### Claim 5 (depends on 1) The liquid disposal tool of claim 1 wherein said absorbent further comprises at least one of sawdust, corn cob, or cat litter. ### Claim 6 (depends on 1) The liquid disposal tool of claim 1 wherein said insert tray is formed from scrap news print or sugar cane pulp that has been emulsified into liquefied slurry that is injected into a mold. ### Claim 7 (depends on 1) The liquid disposal tool of claim 1 wherein said insert tray is made of at least one of a paper, cardboard, plastic, oriented strand board (OSB), sugar cane, and any composite material containing any of the aforementioned. ### Claim 8 (depends on 1) The liquid disposal tool of claim 1 wherein said diffuser sheet is made of an open weave fabric of polypropylene, polyethylene, polyamides, polystyrenes, and cellulosics. ### Claim 9 (depends on 1) The liquid disposal tool of claim 1 wherein said diffuser sheet has a center taper that creates a reservoir to accommodate the on-rush of said liquid. ### Claim 10 (depends on 9) The liquid disposal tool of claim 9 wherein said center taper is created by attaching stringers to fabric of said diffuser sheet with one of ultra-violet light (UV) activated adhesives, hot melt glues, or contact adhesives. ### Claim 11 (depends on 1) The liquid disposal tool of claim 1 wherein said absorbent further comprises oil eating microbes. ### Claim 12 (depends on 1) The liquid disposal tool of claim 1 wherein said container is made of the same material as said insert tray. ### Claim 13 (depends on 1) The liquid disposal tool of claim 1 wherein said set of conical depressions have slits or holes. ### Claim 14 (depends on 1) The liquid disposal tool of claim 1 wherein said insert tray further comprises: an upper rim that extends above said flat top pedestals and defines a collection volume between said diffuser sheet and said flat top pedestals. ### Claim 15 (depends on 1) The liquid disposal tool of claim 1 wherein said insert tray further comprises: a lower rim that extends below said conical depressions and defines an area to place the absorbent between said bottom portion and said insert tray. ### Claim 16 (depends on 1) The liquid disposal tool of claim 1 wherein the liquid disposal tool is a disposable oil change kit (DOCK) that collects dirty oil during an engine oil change. ### Claim 17 A liquid disposal tool for the collection and disposal of liquids comprising: an under tray; an absorbent resting on said under tray, said absorbent configured to collect said liquid; an insert tray covering or supporting said absorbent; and a diffuser sheet overlaying said insert tray, said diffuser sheet joined at a top portion of said insert tray. ### Claim 18 (depends on 17) The liquid disposal tool of claim 17 wherein said absorbent further comprises at least one of sawdust, corncob, cat litter or a polyalkylenes. ### Claim 19 (depends on 17) The liquid disposal tool of claim 17 wherein said absorbent is a peat moss that has been specially processed and is capable of absorbing liquids with total encapsulation. ### Claim 20 (depends on 17) The liquid disposal tool of claim 17 wherein said under tray is made of materials comprising paper, cardboard, plastic, oriented strand board (OSB), sugar cane, and composite material containing any of the aforementioned.
