ABSTRACT:
The earth has several subduction zones where the tectonic plate descends, adjacent the nondescending earth crust, into the central region of the earth. Described is a method and apparatus for the disposal of nuclear and other toxic waste materials comprising the placing of the waste materials into bore holes drilled in the tectonic plate at the edge of the subduction zone and allowing the descending tectonic plate to carry the waste material into the center of the earth. Millions of years are required before the waste can return to the earth's environment and, therefore, the decay of the waste material over this time span will render it harmless. The apparatus comprises re-entry towers that are positioned over the bore holes for loading into the bore holes waste materials made in the form of elongated cylinders or waste material made in the form of spheres.
