New LCD Recycling Technology Wins Prestigious R&D 100 Award 2017

SEATTLE (Scrap Monster): The innovative technology to recycle liquid crystal display (LCD) waste, developed by Taiwan’s Industrial Technology Research Institute (ITRI) has been selected as the winner of the prestigious R&D 100 Award 2017. The recycling technology also received special recognition by the awards jury. The winners of the 55th Annual R&D Awards were announced during the R&D Conference & Awards Ceremony held Nov 17th at the Walt Disney World Swan Resort in Orlando, Florida.

The award-winning recycling system involves a six-step process comprising of separation, extraction, purification, scrubbing, concentration and modification. ITRI is believed to have taken almost five years in research and development of the new system, with the active participation and support of e-scrap processors and Original Equipment Manufacturers (OEMs) in Taiwan. Also, it had partnered with Fortune WEEE Solution Inc. to set up a pilot LCD recycling plant in New Jersey.

The revolutionary technology separates the three main components of LCD panels- liquid crystals, indium and glass from waste LCD panels and recycles each component for future use. As per estimates, every ton of waste LCD panel produces around one kilogram of liquid crystal, 250 grams of indium and 850 kilograms of glass.

According to ITRI, the recycling system generates pure liquid crystals, whose properties are comparable with those of a new product. The systems boasts nearly 100% recovery rate. The technology transforms LCD waste into valuable products. For instance, the recycled crystal displays are commonly used as sound-proof and heat-insulating materials and also as heavy-metal adsorbent in waste water treatment plants.

According to ITRI, the zero-waste, low-cost technology offers significant environmental benefits too. If buried in soil, these panels could prove more harmful to environment than plastic products. Incineration of the LCD panels leads to emission of CFCs which in turn could cause damage to ozone layer. Further, incomplete incineration could lead to release of more toxic chemicals like dioxin and polychlorinated biphenyl into the environment. In short, reusing the panels prevents environmental pollution, ITRI noted.

The R&D Awards, widely recognized as “Oscars of Innovation”, are considered as the most prestigious global recognition of innovation and invention. The winners across various categories are selected by an eminent and independent panel of more than 50 judges representing industry leaders in various disciplines.
