由于经济的增长和信息技术的进步，电子垃圾的数量正在迅速增加。报废（EOL）阴极射线管（CRT）电视和电脑显示器在电子垃圾总量中所占比例最大。由于二手CRT电视和显示器及其中含有的有毒物质的国际贸易，CRT的EOL命运成为发展中国家日益关注的问题。本研究以东南亚三个国家（印尼、菲律宾和越南）的EOL CRT电视/显示器的回收和处理技术为研究对象。并对目前日本和中国CRT电视/显示器的回收方法进行了比较。对正式和非正式回收地点的材料或零件的工艺流程和目的地进行了比较。在这三个国家中，只有菲律宾一家正式工厂拥有crt的自动化加工设备。非正规部门处理的CRT玻璃被非法倾倒或与普通城市固体废物一起处置。一些废弃的CRT玻璃也被非正式地作为玻璃材料回收或出口到中国。提出了一些建议，以改善正式和非正式回收地点的回收条件。
The amount of electronic waste (e-waste) is rapidly increasing due to economic growth and the advancement of information technology. End-of-life (EOL) cathode ray tube (CRT) TVs and computer monitors make up the greatest proportion of the total mass of e-waste. Because of international trade in secondhand CRT TVs and monitors and the toxic substances contained in them, the EOL fate of CRTs is an emerging concern in developing countries. In this study, the recycling and treatment techniques of EOL CRT TVs/monitors were investigated in three Southeast Asian countries (Indonesia, the Philippines, and Vietnam). The current recycling methods of CRT TVs/monitors in Japan and China were also reviewed for comparison. The process flows and destinations of materials or parts at both formal and informal recycling sites were compared. Among the three countries, only one formal facility in the Philippines has automated processing equipment for CRTs. CRT glass handled by informal sectors was illegally dumped or disposed of with regular municipal solid waste. Some waste CRT glass was also informally recycled as glass materials or exported to China. A number of recommendations are made to improve recycling conditions at both formal and informal recycling sites.
