ABSTRACT:
A system and method is provided for producing a safely disposable end product from waste matter containing undesirable materials, such as infectious, biohazardous, hazardous, or radioactive elements. The method comprises the steps of providing a highly basic solvent, immersing the waste matter containing the undesirable materials within the highly basic solvent, and heating the solvent. The waste matter containing the undesirable materials is allowed to remain within the solvent until digested, thereby forming a solution void of any infectious or biohazardous elements and/or containing a decreased concentration of radioisotope.
