Abstract
A method and apparatus for infectious waste treatment. First, the infectious waste may be shredded into a mixture of liquid and shredded solid waste, then the mixture may be poured into a plurality of perforated bags. The liquid waste drips from the perforated bags onto a preheating subsystem and the solid waste remains in the perforated bags. The preheating subsystem heats up the liquid waste to a pre-disinfection temperature. Finally, steam may be utilized to heat up the liquid waste and the solid waste to a disinfecting temperature.
