Abstract

The introduction of liquid-crystal display (LCD) for television and personal computer monitor has gained momentum in sales and distribution due to its portability and energy efficiency over traditional bulky cathode-ray tube (CRT) used in the manufacture of television and personal computer. The disposal of the cathode-ray tube is further having a major challenge due to its hazardous characteristics resulting from the composition of glass used in cathode-ray tubes. There are various recycling technologies available to extract toxic lead from funnel glass of cathode-ray tube. This chapter explores the status of cathode-ray tube, disposal, and environmental issues followed by potential challenges of segregating funnel and panel glass of cathode-ray tube. Separation of funnel and panel glass from the cathode-ray tube based on open-loop and closed-loop process is discussed with pros and cons. Cathode-ray tube glass-ceramic brick and concrete, vitrification glass to stabilize nuclear waste, and fluxing materials such as silica flux are gaining momentum on the reuse of cathode-ray tube under closed-loop process. The diamond cutting method for segregation of funnel glass from panel glass is highly recommended among the various potential segregation technologies available due to its vacuum adsorption and dust recovery capacity, automatic edge searching, and laser positioning. The study finds that emerging technology using furnace and chemicals for extraction of toxic lead from the cathode-ray tube is a promising method for management of recycling in an environmentally sustainable way without any residual waste.
