Abstract

Abstract: With the development of kinescope technology, the quantity of discarded cathode ray tubes (CRTs) glass continues to increase. The waste CRTs glass contains a lot of lead, which could bring about the environmental risk. Based on the research status on the treatment of lead-containing glass in waste CRTs, the technologies of lead separation and recycling were summarized, and their characteristics and developments were analyzed. It was pointed out that the further research and development of new technologies in this field should pay close attention to two aspects, one is the environmental risk in the product realization process of recycling waste CRTs, and another is the satisfiability to economic feasibility and the recycled productsfrom lead-containing Glass in waste CRTs.
