Abstract: A method and apparatus are provided for removing liquids from biological waste by the employment of centrifugal force to separate the liquid from the biological waste particulate and into a container separate from a biological waste container, permitting the dried biological waste and removed liquid to be separately and conveniently disposed of. Preferably, a rotatable drum can be rotatably supported within an outer liquid-tight drum, and a disposable porous container, such as a bag made of porous material, can be placed within the rotatable foraminous drum. Biological waste can be placed within the porous, disposable container within the rotatable drum, and the rotatable drum can be rotated at a rate of rotation sufficient to substantially transfer unabsorbed liquid from the biological waste through the disposable porous container and the openings in the foraminous inner drum to the outer liquid-tight collection drum.

Abstract: A processing chamber for the treatment and decontamination of biological or medical waste includes a rotating waste treatment system carried within an open-top processing chamber, a cap for closing the chamber opening, a gas-pervious liner carried within the chamber for preventing waste from adhering to the underside of the cap as a result of waste-treatment operations, a sealing member disposed at and for sealing the interface of the cap and the processing chamber, and a chemical indicator carried within the interior of the processing chamber for confirming the presence of decontaminant during a waste treatment cycle.

Abstract: An apparatus for the treatment of medical waste, including solid and non-solid materials, permits the collection of such medical waste at the point and at the time of its generation in a solid container. The contained medical waste can be subsequently transported for pulverization, decontamination and safe disposal. A separate portable processing chamber, with an integral means to treat medical waste, can be used at locations remote from its power unit for the collection of medical waste and then moved to the location of the power unit to drive the waste-treatment means within the chamber.

The collected liquids may be disposed of by pumping them into a sanitary sewer.
