ABSTRACT:
A method of encapsulating and sterilizing waste material is disclosed. Medical waste is deposited inside of a mold. When full, the mold is charged with plastic and one of several reactants. The mold is then heated while rotated biaxially. The heat simultaneously sterilizes the waste and causes the charging materials to expand and envelop the waste, encapsulating it. The mold is then cooled while spinning biaxially, forming a hollow brick of solidified, encapsulated material in the mold. The brick of material is removed and pulverized into granules. The pulverized material is separated and readied for recycling.
