Review of air pollution control
2019 Major Air Pollution Control Projects
● Improvement of white smoke and odor in stripper exhaust, and addition of new stripper exhaust recovery and treatment unit. After adding the defroster to the stripper, white smoke and odor have disappeared, with extra benefits of about NT$20 million/year.
● Addition of the fourth RTO-VOC system. RTO (04) and zeolite rotor (G, H). Increased treatment air flow to 240,000 NCMH with a removal rate of 95%, superior to the regulatory VOC removal rate at 85%.
● Zeolite rotor replacement, VOC-A rotor renewal. Superior to the regulatory VOC removal rate at 85%.
● Implementation of the wet scrubber and active carbon tower. The VOC removal rate of the previous active carbon filtering system was 30-60%. After the improvement, the removal rate has been raised to 90%, superior to the regulatory VOC removal rate at 75%.
Waste Liquid Crystal recycling
Innolux cooperated with ITRI (Industrial Technology Research Institute) to introduce the world's first waste liquid crystal recycling technology. In 2019, the project achieved a milestone and started implementation. A liquid crystal separation center at Innolux facility started recycling liquid crystal from LCD panels and reused it after treatment. Such circular process could not only reduce operation cost and waste, but also achieve a financial benefit of saving hundreds of millions of NT dollars each year, of which 150 million dollars for liquid crystal procurement was saved. The treatment center could process 3 tons of waste LCD panel a day and set a role model of circular economy among technology industry.
