No. 137: A technology to recycle liquid crystal display TVs completely (January 1, 2013)

Sharp developed a technology to recycle used liquid crystal display (LCD) TVs completely in alliance with Osaka Prefecture University. They successfully created zeolite by reacting pulverized glass in the alkaline solution. Zeolite is expected to enjoy stable demand because it can be used as a soil improvement agent. 

Glass of LCD panel is hard to recycle because it has a protective film on it, and LCD TV makers provide it to recycling manufacturers as a cement material for virtually free. The LCD TV is subject to Home Appliance Recycling Law, and consumes share the cost for recycling. They pay about 2,800 yen for each larger-than-16 inch LCD TV. It is estimated that 600,000 LCD TVs were discarded in 2011. The number of discarded LCD TVs is estimated to increase to 2,600,000 units in 2015 and 5,000,000 units in 2020. Sharp plans to put the technology into practical use in 2015 and provide it to other home electronics companies.
