NOVELTY - High-pressure steam sterilization for classification disposal and fuel preparation of medical waste comprises sterilizing and classifying medical waste; separating out the first kind of material mainly made of fiber and other organic material; crushing the first kind of material; mixing the crushed material with bituminous coal at 100:30-40 ratio; adding binder; pressing into mold by forming machine after mixing with water; and natural drying to obtain fuel block.    USE - Method of high-pressure steam sterilization for classification disposal and fuel preparation of medical waste (claimed).    ADVANTAGE - Because the method provides material that has little organic material and harmful material, groundwater and air are not polluted after the material is buried; and the complicated treatment for land burying is not required. The method recycles raw material sources; and reduces energy consumption and air pollution.    DETAILED DESCRIPTION - High-pressure steam sterilization for classification disposal and fuel preparation of medical waste comprises sterilizing and classifying medical waste; separating out the first kind of material mainly made of fiber and other organic material; crushing the first kind of material; mixing the crushed material with bituminous coal at 100:30-40 ratio; adding binder; pressing into mold by forming machine after mixing with water; and natural drying to obtain fuel block. Sterilizing and classifying the medical waste comprises using sealing collecting method to classify and collect the medical wastes; primarily crushing the centrally-treated material under sealing condition; high-pressure steam sterilizing all the crushed material; primarily classifying the material into four kinds according to material ratio and magnetism; secondarily crushing the material to obtain particle diameter below 2 mm; secondarily classifying the secondarily-crushed material, separating, and putting into corresponding kinds of material; recycling the first, second, and third kinds of material; and putting the fourth kind of material into special waste incinerator for burning. The first kind of material is light material mainly made of fiber and other organic material. The second kind of material is heavy material mainly made of metal and ore. The third kind of material is magnetic material containing high ratio of iron and other metals. The fourth kind of material is other material mainly comprising organic material.
