ABSTRACT:
A method and apparatus are disclosed for sterilizing biological waste. The waste material is introduced into a shredder mechanism to chop the material into particles of reduced size, which are transmitted into a preheating chamber. Steam is introduced into the chamber to preheat the particles to at least 140 degrees Fahrenheit. A selected amount of the preheated particles are continuously transmitted into a sterilization chamber and steam is introduced into the sterilization chamber to heat the preheated particles to at least 248 degrees Fahrenheit for a sufficient duration such that the particles are sterilized.
