Abstract
Abstract The system (10) for collecting and disposing of medical sharps such as personal use insulin syringes 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, non-natural cellulose, and other materials and 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 medical wastes, and for enhancing the combustion of the medical sharps and other medical wastes when the housing is placed in a furnace. The system for collecting and disposing of medical wastes when burned, evolves no more than trace levels of sulfur or chlorine and yields substantially only biodegradable ash.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
71 words
A process of disposing of medical wastes comprising: placing used medical wastes in a holding chamber of a collector, said collector being fabricated substantially only of combustible materials and including absorptive material, absorbing with the absorptive material liquids emitted from the medical wastes, placing the collector in a furnace environment, and combusting within the furnace environment the collector with the medical wastes confined within the collector during combustion of the collector.
Claim 2
Dependent Claim
71 words
A process of disposing of medical wastes comprising: placing used medical wastes in a holding chamber of a collector, said collector being fabricated substantially only of combustible materials and including absorptive material, absorbing with the absorptive material liquids emitted from the medical wastes, placing the collector in a furnace environment, and combusting within the furnace environment the collector with the medical wastes confined within the collector during combustion of the collector.
Claim 3
Dependent Claim
14 words
The process of claim 1 and wherein said collector is fabricated of biodegradable material.
Claim 4
Dependent Claim
23 words
The process of claim 1 and wherein said collector is fabricated of paper and cellulosic materials with substantially no chlorine or sulfur content.
Claim 5
Dependent Claim
38 words
The process of claim 1 and wherein said collector is fabricated of combustible materials which when burned evolves no more than trace levels of chlorine or sulfur, and which yields only mineral ash or biodegradable ash upon combustion.
Claim 6
Dependent Claim
67 words
The process of claim 1 and wherein said collector is fabricated of combustible materials selected from the group consisting of: natural cellulosic materials such as paper stock, cardboard, fiberboard, particle board, wood, and molded cellulose, non-natural cellulosic materials such as rayon, cellophane, and cellulose-nitrate, and other materials such as natural rubber and natural wax, which when burned their gases of combustion are substantially free of toxic fumes.
Claim 7
Dependent Claim
65 words
The process of claim 1 and wherein said collector is fabricated of combustible materials selected from the group consisting of: natural cellulosic materials such as paper stock, cardboard, fiberboard, particle board, wood, and molded cellulose, non-natural cellulosic materials such as rayon, cellophane, and cellulose-nitrate, and other materials such as natural rubber and natural wax, which when burned will leave only mineral ash or biodegradable ash.
