Recycling of CRT waste is not economically profitable due to its toxicity and, at the same time, it has a limited number of reuse options. For technology products that are no longer in demand, such as CRT, it is not profitable to recycle them to be used in the production of CRT again. However, since these types of waste are often composed of different types of substances and are disposed by consumers in inappropriate ways, the additional expenditure incurred in the collection, storage, and disintegration, reduces the recycling rate. For this reason, e-waste is a possible source of economic benefits. The recycling of the various components contained in e-waste, such as metal, plastic, and circuit boards, is often more efficient than their production from raw materials. Lead is particularly harmful to the environment and is the most commonly found heavy metal in CRT devices. These components can be absorbed by soil over time, and can be passed indirectly to animals and humans. CRT wastes should be specially stored because of the harmful components they contain. CRT waste is an important part of electronic waste globally. CRT technology is still in use it is the cheapest TV product in Eastern Europe, the Middle East and in African countries that cannot acquire LCD and LED TVs. However, with the addition of liquid crystal display (LCD) and light emitting diode (LED) monitors with higher resolution fineness to the market, CRT monitors have been discontinued in many countries and have become electronic waste. ![]() ![]() It is a widely applicable technology and it has been widely preferred for a long time due to its easy accessibility, price compatibility, and long life. This technology, which is commonly used in television (TV) monitors, has also been used in computers and in many technological devices over time. KeywordsĬathode ray tube (CRT), E-waste, Recycling, Electron gun IntroductionĬathode ray tubes (CRTs) are an old technology that was globally used for over 60 years. For this reason, poisonous components in glass ceramic structures found in CRT monitors can be confined and used in closed-loop recycling for various sectors. Furthermore, because CRT technology is obsolete, it is not profitable to use CRT as a raw material again. However, the toxic substances they contain prevent them from being transformed into glass for everyday use. CRT monitors contain different types of glass constructions and they can therefore be recycled. However, some types of waste, such as CRT TVs and computer monitors, form hazardous waste piles due to the toxic components (lead, barium, strontium) they contain. Large parts of electronic waste can be recycled for reuse. As a result, such devices have accumulated as electronic waste and constitute a new problem. The use of liquid crystal display (LCD) and light emitting diode (LED) monitors has rapidly reduced the use of cathode ray tube (CRT) technology in computers and televisions (TVs). The developments in monitor technology have accelerated in recent years, acquiring a new dimension.
