Abstract
Abstract A waste management disposal system which disposes of both solid and aerosol waste includes a housing divided into a solid waste containment area and a negative pressure plenum for drawing aerosol waste away from the solid waste containment area. A funnel is provided for guiding solid waste into the waste containment area and the negative pressure plenum draws the aerosol waste in a path orthogonal to the funnel. A filter is provided for filtering the aerosol contaminants from the air upon which it is being transported.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
128 words
A waste management disposal system for disposing solid and aerosol waste comprising a housing, the housing defining a solid waste containment chamber within said housing for receiving solid waste deposited within said housing; said waste containment chamber being formed with an entrance opening to allow waste to pass into said containment chamber; guide means for guiding said solid waste into said solid waste containment area; pressure inducing means positioned at or above said entrance opening without said containment chamber for causing solid waste to be deposited within said solid waste containment chamber while drawing aerosol waste away from said solid waste containment chamber in a path substantially orthogonal to said guide means; and filter means for filtering contaminants drawn from said aerosol waste by said pressure inducing means.
Claim 2
Dependent Claim
128 words
A waste management disposal system for disposing solid and aerosol waste comprising a housing, the housing defining a solid waste containment chamber within said housing for receiving solid waste deposited within said housing; said waste containment chamber being formed with an entrance opening to allow waste to pass into said containment chamber; guide means for guiding said solid waste into said solid waste containment area; pressure inducing means positioned at or above said entrance opening without said containment chamber for causing solid waste to be deposited within said solid waste containment chamber while drawing aerosol waste away from said solid waste containment chamber in a path substantially orthogonal to said guide means; and filter means for filtering contaminants drawn from said aerosol waste by said pressure inducing means.
Claim 3
Dependent Claim
25 words
The waste management disposal system of claim 1, wherein the guide means comprises at least one truncated tetrahedron extending into said solid waste containment area.
Claim 4
Dependent Claim
20 words
The waste management disposal system of claim 2, wherein said guide means is pivotably and releasably disposed within said housing.
Claim 5
Dependent Claim
40 words
The waste management disposal system of claim 3, further comprising a back splash plate affixed to said housing, said guide means including a flange extending from a rear edge of said guide means, said back splash plate overlapping said flange.
Claim 6
Dependent Claim
42 words
The waste management disposal system of claim 3, wherein said guide means pivots from a waste guiding position to a non-waste guiding position; and further comprising clip means mounted on said housing for selectively maintaining said guide means in the non-guide position.
Claim 7
Dependent Claim
18 words
