E-waste as Waste Electrical and Electronic Equipment is a waste type consisting of any broken or unwanted electrical or electronic appliance. Recyclable electronic waste is sometimes further categorized as a "commodity" while e-waste which can not be reused is distinguished as "waste". Both types of e-waste have raised concern considering that many components of such equipment are considered toxic and are not biodegradable. Responding to these concerns, many European countries banned e-waste from landfills in the 1990s. The European Union would further advance e-waste policy in Europe by implementing the Waste Electrical and Electronic Equipment Directive in 2002 which holds manufacturers responsible for e-waste disposal at end-of-life. Similar legislation has been enacted in Asia, with e-waste legislation in the United States limited to the state level due to stalled efforts in the United States Congress regarding multiple e-waste legislation bills. Due to the difficulty and cost of recycling used electronics as well as lackluster enforcement of legislation regarding e-waste exports, a staggering amount of used electronics has made its way into countries such as China, India, and Kenya where lower environmental standards and working conditions make processing e-waste more profitable. ewaste If treated properly, electronic waste is a valuable source for secondary raw materials. However, if not treated properly, it is a major source of toxins and carcinogens. Rapid technology change, low initial cost and even planned obsolescence have resulted in a fast growing problem around the globe. Technical solutions are available but in most cases a legal framework, a collection system, logistics and other services need to be implemented before a technical solution can be applied. Electronic waste represents 2 percent of America's trash in landfills, but it equals 70 percent of overall toxic waste. Due to lower environmental standards and working conditions in China, India, Kenya, and elsewhere, electronic waste is being sent to these countries for processing – in most cases illegally. Guiyu in Shantou region of China, and Delhi and Bangalore in India, all have electronic waste processing areas.[2] Uncontrolled burning, disassembly, and disposal are causing environmental and health problems, including occupational safety and health effects among those directly involved, due to the methods of processing the waste. Trade in electronic waste is controlled by the Basel Convention. Electronic waste is of concern largely due to the toxicity and carcinogenicity of some of the substances if processed improperly. Toxic substances in electronic waste may include lead, mercury, cadmium. Carcinogenic substances in electronic waste may include polychlorinated biphenyls (PCBs). A typical computer monitor may contain more than 6% lead by weight, much of which is in the lead glass of the CRT. Capacitors, transformers, PVC insulated wires, PVC coated components that were manufactured before 1977 often contain dangerous amounts of polychlorinated biphenyls. Up to thirty-eight separate chemical elements are incorporated into electronic waste items. The unsustainability of discarding electronics and computer technology is another reason for the need to recycle – or perhaps more practically, reuse – electronic waste. E-waste is often exported to developing countriesElectronic waste processing systems have matured in recent years following increased regulatory, public, and commercial scrutiny, and a commensurate increase in entrepreneurial interest. Part of this evolution has involved greater diversion of electronic waste from energy intensive, down-cycling processes where equipment is reverted to a raw material form. This diversion is achieved through reuse and refurbishing. The environmental and social benefits of reuse are several: diminished demand for new products and their commensurate requirement for virgin raw materials and larger quantities of pure water and electricity for associated manufacturing, less packaging per unit, availability of technology to wider swaths of society due to greater affordability of products, and diminished use of landfills. Challenges remain, when materials cannot or will not be reused, conventional recycling or disposal via landfill often follow. Standards for both approaches vary widely by jurisdiction, whether in developed or developing countries. The complexity of the various items to be disposed of, cost of environmentally sound recycling systems, and the need for concerned and concerted action to collect and systematically process equipment are the resources most lacked -- though this is changing. Many of the plastics used in electronic equipment contain flame retardants. These are generally halogens added to the plastic resin, making the plastics difficult to recycle.

computer monitorA computer display monitor, usually called simply a monitor, is a piece of electrical equipment which displays viewable images generated by a computer without producing a permanent record. The word "monitor" is used in other contexts; in particular in television broadcasting, where a television picture is displayed to a high standard. A computer display device is usually either a cathode ray tube or some form of flat panel such as a TFT LCD. The computer monitor comprises the display device, circuitry to generate a picture from electronic signals sent by the computer, and an enclosure or case. Within the computer, either as an integral part or a plugged-in interface, there is circuitry to convert internal data to a format compatible with a computer monitor. computer monitor As with television, several different hardware technologies exist for displaying computer-generated output: Liquid crystal display (LCD). TFT LCDs are the most popular display device for new computers in the Western world. Passive LCD gives poor contrast and slow response, and other image defects. These were used in some laptops until the mid 1990s. TFT Thin Film Transistor LCDs give much better picture quality in several respects. All modern LCD monitors are TFT. Cathode ray tube (CRT) Standard raster scan computer monitors Vector displays, as used on the Vectrex, many scientific and radar applications, and several early arcade machines (notably Asteroids - always implemented using CRT displays due to requirement for a deflection system, though can be emulated on any raster-based display. Television receivers were used by most early personal and home computers, connecting composite video to the television set using a modulator. Image quality was reduced by the additional steps of composite video ? modulator ? TV tuner ? composite video. Plasma display Surface-conduction electron-emitter display (SED) Video projector - implemented using LCD, CRT, or other technologies. Recent consumer-level video projectors are almost exclusively LCD based. Organic light-emitting diode (OLED) display Penetron military aircraft displays Wiki computer monitor |
