The types of waste electronic and electrical equipment include: refrigerators, washing machines, microwaves, air conditioners, and other large household appliances; Small household appliances such as vacuum cleaners and electric shavers; Information technology (IT) and remote communication equipment such as computers, printers, fax machines, copiers, telephones, etc; User equipment such as radios, televisions, cameras, audio systems, etc; Electronic and electrical tools such as drilling machines and electric saws; Electronic toys, leisure and sports equipment; Medical devices such as radiation therapy equipment, heart disease treatment equipment, and fluoroscopy equipment; Monitoring and control tools such as smoke detectors and automatic temperature regulators; Various vending machines. Electronic waste refers to abandoned electronic and electrical equipment and its components. Including: non-conforming equipment and its components generated during the production process; Scrap products and discarded components generated during the maintenance process; Consumer waste equipment; According to relevant laws and regulations, equipment and its components that are considered electronic waste. [2] One obvious characteristic of waste electronic and electrical equipment is its wide variety and large quantity, and WEEE almost involves every corner of production and life. The coexistence of resource and pollution is another characteristic of WEEE, which is mainly composed of metals, ceramics, glass, plastics, rubber, semiconductors, composite materials, and various chemical substances. The recyclability of electronic waste is high, and in addition, circuit boards also contain precious metals such as gold, palladium, platinum, silver, as well as rare elements such as tantalum, niobium, and cerium. Therefore, it has important economic value for the recycling and utilization of WEEE. Treatment of waste electronic and electrical equipment ① Incineration treatment ② Landfill treatment ③ Physical and mechanical methods for recovering copper, precious metals, etc. ④ Thermochemical methods for obtaining chemical raw materials, gas fuels, or liquid fuels
