Apparatus and method for processing regulated medical waste using a processing oven having multiple temperature ranges and compacting means and an oven with means for sensing and generating heat near the base of the medical waste container. Temperature-calibrated thermoplastic engineered to liquefy at temperatures assuring sterilization of biological contaminants within the time frame of liquefaction and re-solidification is formed into a waste-receiving hopper capable of withstanding waste compaction pressures prior to liquefaction and compaction states are performed both before and after liquefaction. Self-lidding thermoplastic containers utilize the mass of thermoplastic covers, or other forces, to consolidate the mass. A laminate is applied to the container to control plastic flow during liquefaction.
A self-lidding thermoplastic container for receiving regulated medical waste and for facilitating verifiable thermal processing of the waste into non-regulated form for disposal, comprising:
An expendable thermoplastic container for receiving medical waste and for facilitating verifiable thermal processing of the waste into form for disposal, comprising:
An oven assembly for processing regulated medical waste in situ comprising a waste treatment space for receiving the waste in conjunction with a mass of temperature calibrated thermoplastic, means to provide processing heat selectively in at least two different processing temperature ranges one of which is below the temperature of liquefaction of the thermoplastic and one of which is at or above the temperature of liquefaction, and timer means to control the duration of each processing operation.
A method for heat-processing regulated medical waste selected from among breakable, compressible, thermoplastic and metallic items, the steps of
