A bulk receiving system is provided for receiving, processing and transferring materials from one or more collection stations. The system further includes processing for sizing and segregating metal extracted from a contaminated hazardous waste stream. Methods are provided for providing induction of forced, combustion air directly into the calcining zone of a rotating cement kiln.
