Taiwan-developed LCD waste recycling system wins R&D 100 Award

Blaze Display Technology Co., Ltd. | Updated: Dec 06, 2017

【R&D Department of Blaze Display】Taipei, Nov. 20 (CNA) A system developed by Taiwan's top Industrial Technology Research Institute (ITRI) to recycle toxic liquid crystal display (LCD) waste has won an R&D 100 Award for 2017, which honors revolutionary technology from around the world over the past year.

The waste recycling system, touted as zero-waste, eco-friendly and cost-effective, also earned special recognition from the R&D 100 Awards jury, which honors the top 100 R&D pioneers and their revolutionary ideas in science and technology every year, ITRI said Monday.

Addressing the innovative recycling system at a press conference that day, Hung Huan-i of ITRI's Material and Chemical Research Laboratories said if the liquid crystal sealed in a LCD glass panel is buried in dirt, it can cause greater harm to the environment than plastic products.

Even if the toxic substance is incinerated, the chlorofluorocarbons produced during the burning process spread in the air, destroying the ozone layer, Huang pointed out.

In addition, he went on, if the incineration is incomplete, more toxic chemicals, including dioxin and polychlorinated biphenyl can be released into the environment.

Believing the best way to prevent liquid crystals from polluting the environment is to reuse them, Huang said their research team integrated sequential separation, ppb-level purification and nanopore technologies to recycle liquid crystals, indium and glass from waste LCD panels.
