System for sorting plastic objects for recycling.

摘要

A method and an apparatus for sorting plastic objects particularly containers and films for recycling wherein if it is first determined that the plastic object is clear, the plastic object will be ejected. If the plastic object is not determined as being clear, the apparatus or method next determines if the plastic object is colored. If the plastic object is colored, the plastic object will be ejected. The above method may also be accomplished by use of a truth table which analyzes the characteristics of the plastic object. Also provided is a detector for detecting the presence of chlorine in a plastic object by means of X-ray fluorescence. Sorter means sort the plastic objects into small diameter and large diameter objects. <IMAGE>
