Abstract
Many kinds of high-tech products require rare metals in order to function. This is also true in the case of LCDs (liquid crystal displays), which are currently in increasing demand. The LCD is a product requiring indium resources for its transparent electrode material. As the production of LCD TVs increases, the demand for indium will simultaneously increase in the future. This makes it important for LCD manufacturers to plan for the securing of indium resources, of which production is in limited quantity. We are developing technologies that work to recover indium resources from LCDs. In particular, the simple and energy-saving ion-exchange resin method is proving to be significant. We have constructed demonstration equipment that can process 240kg of waste LCD panels per day, achieving a recovery rate of 94%.
