Abstract

An apparatus for neutralizing and disposing of infectious solid waste and non-hazardous solid waste includes a housing having an upper chamber for receiving the infectious solid waste and a lower chamber for receiving the non-hazardous solid waste. The upper chamber includes an exterior loading door, and an interior discharge door. A discharge ram forms one wall of the upper chamber opposite to the discharge door. The upper chamber includes door seals and pressure fittings so that the infectious waste placed therein may be sterilized by steam introduced under pressure. The neutralized wastes are ejected by the discharge ram through the interior door into the lower chamber. One wall of the lower chamber comprises a compactor ram which is extendable through a discharge opening to compress the neutralized and non-hazardous wastes into a closed compactor container.

Dependent claims

Apparatus for receiving, treating, and disposing of bio-hazardous or infectious solid wastes and non-hazardous or non-infectious solid wastes, comprising a housing defining a pair of discrete separate adjacent chambers, the first of said chambers being enclosed and having an opening therein through which infectious waste may be introduced, said first chamber being adapted to permit steaming and sterilization of the infectious waste, the second of said chambers being enclosed and having an opening therein through which non-infectious material may be introduced, means defining a passage interconnecting said first and second chambers, a closure for selectively opening and closing said passage, means for ejecting the sterilized contents from said first chamber into said second chamber through said passage when said closure is in an open position, and compaction means in said second chamber for selectively compacting the non-infectious waste and for compacting the infectious waste received from said first chamber and for ejecting all of such waste from said housing at one end of said second chamber.
