Abstract:
A method for converting infectious organic waste material selected from the group consisting of food waste, food processing waste, animal carcasses, animal body parts, animal organs, animal tissues, and mixtures thereof, into a denatured, value-added solid, plant or animal nutrient product, wherein the infectious organic waste material contains solid and liquid components, the method comprising(a) comminuting absorbent organic fibrous material from a source other than the infectious organic waste material;(b) mixing the absorbent organic fibrous material with the infectious organic waste material to form a reaction mixture;(c) heating the reaction mixture in a hyperbaric reactor vessel at an elevated temperature and at a superatmospheric pressure for a time sufficient to create saturated steam, to hydrolyze the absorbent organic fibrous material and to convert the reaction mixture into a substantially denatured plant or animal nutrient product containing inactivated pathogenic agents;(d) releasing vapor from the hyperbaric reactor vessel into a condenser;(e) dehydrating the denatured plant or animal nutrient product in the hyperbaric reactor vessel to produce a free-flowing solid denatured plant or animal nutrient product; and(f) discharging the dehydrated free-flowing solid denatured plant or animal nutrient product from the hyperbaric reactor vessel.
