A rotary grinder is described including a hopper for receiving waste through a door, which door when closed, provides a fluid tight seal. A movable waste receptacle is provided beneath the grinder and is locked in place and weighed during the operation of the grinder. An iris diaphragm valve mates with the outlet from the grinder and, when in its open orientation, drops a sleeve into the waste receptacle thereby creating a sealed enclosure for the decontaminated waste material. Cutting blades employed by the grinder are identical and are provided with bearing shoulders which determine the amount of blade exposed when the blades are mounted on rotating arms of the grinder.
