Abstract
Abstract The system (10) for collecting and disposing of contaminated waste products such as medical sharps and other medical wastes includes a housing (11) and its telescopic cover (9) which are fabricated of biodegradable and combustible material such as natural cellulose and non-natural cellulose. An absorbent biodegradable and combustible absorption package (30) or insert (35) can be placed in the bottom of the holding chamber (12) for absorbing any liquids emitted from the sharps and other wastes, and for enhancing the combustion of the medical sharps and other wastes when the housing is placed in a furnace. When the housing is burned it evolves no more than trace levels of sulfur or chlorine and yields substantially only biodegradable ash.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
167 words
A process of burning contaminated wastes comprising: forming a collector fabricated of materials selected from a group consisting of: natural cellulose materials, non-natural cellulose materials, natural rubber and natural wax, which are combustible and biodegradable, and when burned evolve no more than trace levels of chlorine or sulphur and yield substantially only biodegradable ash, said collector defining a holding chamber for receiving contaminated wastes; the collector having been formed of a mass of the material which embodies the collector in comparison with the volume of the holding chamber of the collector to yield a predetermined ratio of the ash of combustion of the collector material with respect to the ash of combustion of the anticipated maximum amount of wastes collected in the holding chamber when the collector and the wastes in its holding chamber are burned; placing the contaminated wastes in the holding chamber of the collector; and combusting in a furnace environment the collector with the contaminated wastes collected in the holding chamber of the collector.
Claim 2
Dependent Claim
167 words
A process of burning contaminated wastes comprising: forming a collector fabricated of materials selected from a group consisting of: natural cellulose materials, non-natural cellulose materials, natural rubber and natural wax, which are combustible and biodegradable, and when burned evolve no more than trace levels of chlorine or sulphur and yield substantially only biodegradable ash, said collector defining a holding chamber for receiving contaminated wastes; the collector having been formed of a mass of the material which embodies the collector in comparison with the volume of the holding chamber of the collector to yield a predetermined ratio of the ash of combustion of the collector material with respect to the ash of combustion of the anticipated maximum amount of wastes collected in the holding chamber when the collector and the wastes in its holding chamber are burned; placing the contaminated wastes in the holding chamber of the collector; and combusting in a furnace environment the collector with the contaminated wastes collected in the holding chamber of the collector.
Claim 3
Dependent Claim
41 words
The process of claim 1 and wherein the step of placing the contaminated wastes in the holding chamber of the collector further comprises: depositing medical wastes, including surgical kit pack trays, gowns, masks, garments, gloves and drapes in the holding chamber.
Claim 4
Dependent Claim
35 words
The process of claim 1 and wherein the step of forming the collector of a mass of the material which embodies the collector further comprises: changing the thickness of the material which forms the collector.
