If you’re outside the San Francisco Bay Area, use our mail-in recycling service. Or if you have a CRT monitor you’re eager to get rid of and you’re in the San Francisco Bay Area, stop by our EcoCenter today and we’ll take it off your hands for free. See step by step how the process works.įor more information about what to do with your old monitors, give us a call at (650) 493-8700. If you want to watch how CRT monitor recycling is done, check out this great video. This process will reduce the impact of mining and keep toxins out of the environment. Once they have been separated, strong magnets with specific electronic charges for each different metal are used to divide the different metals, such as copper, gold, iron, and steel.Īfter these parts are separated, they are often sold to different processors where they will be further refined, then sold production of new materials. They are crushed, vibrated, shredded or sprayed by a strong current of water to separate the different materials. Once the plastics, electronic gun, glass tube, motherboards, wires and other miscellaneous parts have been separated they all undergo the separation process. The glass in CRTs typically contains enough lead to require managing it as hazardous waste under certain circumstances. The lead glass needs to undergo a lead smelting process and can be used to make new CRT monitors. Adding lead to glass is a common practice to improve optical quality and creates a shield against the radiation produced by the electrons. The glass used in the tube generally contains 20% lead by weight. ![]() This phosphorous is removed so the glass can be recycled. Inside the glass is a phosphorus coating which glows when it is hit by light. To prevent the unit from imploding, specialized equipment needs to dismantle it. All of these parts contain different materials that are removed and sorted into separate bins to undergo their own recycling process. The positive charge of the anode draws the electrons from the cathode’s copper components and directs the electrons to create the image. The cathodes are heated filaments which produce a stream of electrons. The electron gun contains the cathode and anode units. This is done manually, exposing the panel glass, glass tube, electronic chip boards, wiring and electron gun. When the dismantling process of the CRT monitor begins, the plastic casing of the monitor is removed. If you choose an electronic recycler with the e-Steward certification you can be confident that it will be properly recycled in the United States. Unfortunately, many electronic collectors ship CRTs overseas where they are often dumped. Next, the CRTs are shipped out of the collection center to the recycling plant for further processing. The recycling process begins with consumers or companies bringing their CRT monitors to an electronic recycling drop off center, like GreenCitizen. Luckily, recycling is a safe and responsible option for those old monitors. The results of these tests are presented in this paper.Got any old CRT (Cathode Ray Tube) monitors you want to get rid of? In recent years, we’ve started to replace cathode ray tubes with LCD displays, leaving consumers with unwanted monitors taking up space. Thus, the wet-scrubbing method is recommended for use as a CRT coating removal method. This study shows that the wet-scrubbing method has a better coating removal performance and no associated pollution problem (i.e., no additional chemical additives). This cleaned CRT glass is intended to be recycled and reused by CRT manufacturers. In this study, the CRT panel and funnel glass obtained from scrap computer monitors was cleaned by wet-scrubbing and ultrasonic cleaning methods. To recycle CRT glass, a series of tests has been conducted to remove the coatings from scrap CRT glass. These coatings may present an adverse effectto the environment by obstructing the recycling and reuse of the CRT glass. Several coatings have been applied to the surface of the CRT panel and funnel glass. A CRT can be divided into panel (front) glass and funnel (back) glass. CRT glass may be considered a hazardous waste due to its high lead concentration. Thus, the successful recycling of scrap CRT glass can greatly relieve the disposal problem created by scrap monitors. It is estimated that approximately 50% of the weight of a computer monitor is composed of cathode ray tube (CRT) glass. ![]()
