A Circular Economy Case of LCD Waste Recycling System
開啟循環經濟 : 廢液晶面板之再利用
Abstract
LCDs have been the main display devices recently. To satisfy the increasing demands, billions of LCDs are manufactured annually. However, as more LCDs are produced and are used, the amount of LCD waste is increasing at an alarming rate. LCD waste can be simply disassembled into a numerous parts, most of which are commonly recycled, but the LCD panels typically are not. Waste LCD panels are generally disposed of in landfills or by physical treatments. To prevent the pollution caused by waste LCD panel disposal, and control processing costs, ITRI thoroughly analyzed the characteristics and reusability of each material contained in LCD panels, and designed a logical separation procedure according to the associations between each material, first separating liquid crystal, indium, and glass, and then developing purification technology for each material which enables the reuse of these materials. Simply put, treating waste LCD panels with this system not only saves money, but can transform the panels’ material (liquid crystals, indium, and glass) into valuable, reusable products, not only increasing profits but effectively reducing the production of waste material. This is also a circular economy case of "cradle to cradle".
液晶顯示器為目前之主流顯示裝置，為了滿足日益增多的使用量，每年生產的不同尺吋液晶顯示器已經超過十億片，當這些產品到了使用年限後，可預期未來每年廢棄量就是現在的生產量。現有的廢棄面板處理模式，主要將廢液晶顯示器先行拆解成數個可回收單元，再依塑料與金屬材料分別進行回收，至於含有液晶與貴重金屬的玻璃廢液晶面板，卻僅能委託廢棄物處理廠進行掩埋，不只浪費材料也會造成環境負擔。工研院依據液晶面板的結構和材料特性，設計一套完整的量產處理程序，可將液晶、貴重金屬銦和玻璃自廢液晶面板中取出、純化後，以材料的觀點將其應用於原製程，或者轉化為高值化的再利用產品，兼具環保與經濟雙重效益，更是一種搖籃到搖籃的循環經濟案例。
