A cathode ray tube (CRT) is the video display unit found in televisions and computer monitors. A picture is created when a stream of electrons travels through a tube and lights up a phosphor coating on the glass face. There are two waste management issues associated with CRT’s: the impact on the environment/health issues attributed to high amounts of lead and glass under pressure, and society's ability to deal with a growing number of discarded items. For these reasons, it is important to properly manage CRTs and then send them to appropriate locations for recycling, reuse, or disposal.
