The Industrial Technology Research Institute (ITRI) of Taiwan has developed a new system for the recycling of LCD screens, by separating them into their three component materials—glass, indium and liquid crystal.
The system is reported to be able to crush the glass, extract and purify the liquid crystal and removes and concentrates indium content, up to three metric tons per day, generating a revenue of $32,000. The ITRI believes the US produces “hundreds of thousands of tons” of LCD waste every year.
The system costs approximately $2,000 to operate and reportedly recovering three kilograms of liquid crystal, 750 grams of indium and about 2,550 kilograms of glass each day.
