The Consumer Electronics Association (CEA) and the Institute of Scrap Recycling Industries Inc. (ISRI) recently announced a technical "CRT Challenge" to identify financially viable, environmentally-conscious proposals for using recycled cathode ray tube (CRT) glass. As CRT technology has been displaced in the market by liquid crystal display (LCD), light-emitting diode (LED) and plasma displays, the consumer electronics and recycling industries are working to find inventive and creative new ways to recycle old CRT glass. Over the coming years, more than two billion pounds of legacy CRT TVs and monitors are expected to enter the recycling stream. And with demand for old CRT glass to make new CRT glass waning, there is an increased need for new environmentally-sound, economically sustainable uses for this material.
