Abstract: A method for producing a hydrolyzed, sterile, denatured product from infectious organic waste material includes (a) introducing, into a reactor capable of being heated and pressurized, infectious organic waste material to form a reaction mixture; (b) subjecting the reaction mixture to saturated steam at a temperature and pressure within the reactor for a duration of time sufficient to thermally hydrolyze and denature the reaction mixture into a denatured slurry; and (c) alternatively (1) anaerobically digesting the denatured slurry, or (2) fractionating the denatured slurry based on molecular weight, density and size into at least two hydrolyzed, sterile, denatured products. The resulting hydrolyzed, sterile products have safe and valuable nutritional properties and may be used in a wide range of commercial, agricultural, and industrial products or processes.
