Abstract: A system for treatment of infectious waste including an impactor coupled to a mixing drum that can be pressurized. Infectious waste is introduced directly into the impactor, where the waste is pulverized, then introduced into the mixing drum through its inlet end for mixing with a treatment fluid effective to kill pathogenic organisms. The drum is sealed, and superatmospheric pressure is applied therein to drive the treatment chemicals into the waste particles. After treatment, the treated waste and treatment chemicals are discharged from the drum through the inlet end of the mixing drum.

Abstract: An system for treatment of infectious waste including a impactor coupled to a mixing drum that can be pressurized, infectious waste and a treatment fluid comprising a substance effective in killing pathogenic organisms being introduced directly into the impactor where the waste is pulverized forming unrecognizable particulate matter mixed with fluid, and the waste from there being introduced into the drum for mixing and subsequently pressure treatment by providing a superatmospheric pressure in the drum to drive chemicals effective in killing pathogenic organisms into voids in the solids and also into spore walls and cell membranes to provide a more speedy and effective kill.
