Method of and apparatus for disposing waste

Abstract

A waste disposal apparatus comprising a crushing means for crushing waste including a circuit board into fragments, and a circuit board sorting means for sorting fragments of the circuit board from the fragments of the waste crushed by the crushing means through eddy current sorting or gravity concentration so as overcome a difficulty in separation between nonferrous metals. With this arrangement, lead contained in the circuit boards can be sorted and separated without being diffused, and further, the volume of fragments of the circuit boards adapted to be mingled into fragments of other waste such as nonferrous metals and plastics can be decreased. Thus, even though waste including circuit board is directly crushed by the crushing means, thereby it is possible to enhance the quality of recovered valuables.
