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. Solid biological waste may then be disposed of by removing the disposable porous container from the rotatable drum with the solid biological waste therein, avoiding by closure of disposable porous container, exposure of handling personnel to the solid biological waste. The collected liquids may be separately disposed of by pumping them into a sanitary sewer. If it is desired, additional liquid, such as a microbial decontaminating agent, may be added within the porous disposable bag as it is being rotated.

Centrifugal apparatus for biological waste disposal

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 separate portable processing chamber includes a rotating waste treatment system that is rotatably carried within the chamber, a plurality of pivotable blades that are carried by rotatable axle pins within a plurality of slots formed in the rotating system, a ring carried by the rotating system to prevent deleterious collections of waste materials, and a plurality of baffle bars are located interiorly of the chamber for preferential treatment of soft and non-soft medical waste material during operation.
