        Consumers increasingly prefer HDTV (high definition television), including LCD (liquid crystal display), LED (light emitting diode), and plasma TVs (television), and existing analog TV broadcasting system will be switched to digital broadcasting at the end of 2012 in Korea. Even for computer monitors, CRT (cathode-ray tube) monitors are no longer preferred because of customers’ increasing desire for thinner and lighter monitors and mobile computers. It is anticipated that these shifts will lead to a dramatic increase in disposal of analog TV sets. In 2012, it is estimated that about 117 thousand tons of CRT glass waste will be generated in Korea. CRT glass waste is not only Korea’s problem but also global issue, which needs worldwide attentions and policies for conserving useful resources and preventing groundwater pollution from heavy metals contained in CRT glass waste in case of landfill. It is important to develop BATs (best available technologies) to recycle CRT glass waste properly in short times. Therefore, in this study recycling possibility of CRT class was evaluated for the clay brick including powder of CRT glass of after crushing. Compressible strength and absorption factor of fabricated sample clay bricks were measured and observed whether they could satisfy the Korean Industrial Standard to use as normal bricks or not. The clay bricks containing under 5% of CRT panel glass powders were found to show enough quality as bricks, therefore the recycling of CRT cullet as materials of clay bricks could be utilized as one of the options.
