Corporate Social Responsibility

Several dozen types of raw materials are used in TFT-LCD production at Innolux. To ensure effective control of the environmental impacts of waste gasses, wastewater, hazardous substances and noise generated in the production processes, the Company has established pollution control facilities and oversight mechanisms. Environmental protection, plant operations and production units cooperate to make improvements and processing capabilities are enhanced through industry-academia projects placed under the purview of the Plant Operations Committee to ensure compliance with related laws and regulations as well as the achievement of economic benefits and environmental protection performance.
Air Pollution Control
The air pollutants released from Innolux include volatile organic compounds (VOCs), nitrogen oxides, sulfur oxides, ammonia, chlorine, nitric acid, phosphoric acid, particulates, etc. During operation, waste gases containing VOCs and acidic, alkaline, and particulate matter are first collected separately in sealed spaces before they are treated with air pollution control equipment according to their properties to bring them into compliance with emissions standards.
 
Major Air Pollution Control Projects in 2018
Each year, Innolux invests around NT$180 million in pollution control, including the installation of new treatment systems and equipment replacements.
 
Plant Projects Executed in 2018 Results
Tainan Improvements to NO2 removal capacity:
Inventory of exhaust concentration at each station along the WETX production line, and separation of acidic exhaust gases and high-concentration NO2 into different pipelines
NO2 concentration was reduced by 60%.
Tainan Replacement of zeolite rotors for disposal of VOCs: replacement of VOC-B rotors VOC removal rate increased by 14% to 95%, exceeding the minimum 75% removal rate specified in the regulations the plant was subject to.
Ningbo Installation of facilities for treating VOC emissions with activated carbon: installation of new scrubbers with activated carbon filters VOC removal rate exceeded 91%, complying with the Law of the People’s Republic of China on the Prevention and Control of Atmospheric Pollution and much higher than the minimum 75% removal rate specified in environmental impact assessment regulations.
Foshan Improvements to VOC disposal equipment: installation of spray-tower scrubbers, and scrubbers with UV photolysis function and activated carbon VOC outlet concentrations dropped to 2-5 mg/m3, complying with the time slot II standard specified in the Guangdong Province Printing Industry VOC Emission Standards (DB 44/815-2010) and VOC outlet concentration criterion of <80mg/m3 specified in Odorous Pollutant Emission Standards (GB 14554-1993).
 
Waste Reduction
Innolux promotes waste reduction at the source as well as recycling. Statistics show the Company generated 104,710 tons of waste in 2018, including about 76,288 tons of ordinary waste and 28,422 tons of hazardous waste. The rate of recycling achieved 84.9% in 2018 and measures taken included the production of organic sludge, reduction of waste copper solutions and solid waste, and reduction of waste alkaline solutions and hazardous waste.

Recycling of Packaging Materials
In 2018, the recycling rate of DSPK boxes was 75.9%, hard boxes 54.8%, and PP boxes 57.6%. Additionally, statistics show a reduction of packaging material weight due to carbon reductions through design, which involve increasing the number of pieces per box, and carbon reductions through recycling that involve using recycled boxes instead of new boxes. These helped bring down emissions by 26,285 tCO2e in 2017.



Low-carbon Logistics
Through cooperation with transport services, except when transportation by sea cannot meet the delivery deadlines of customers and downstream businesses, Innolux continues to ship across the strait with express vessels and also use closer harbors in combination with land shipment. In 2018, the Company even made the decision to ship goods by sea instead of by air. Delivery deadlines were met, transportation costs were reduced and the supply chain continued to function just as well.
 
As a result of improved transportation arrangements and management in 2018, the Company reduced carbon emissions by 955,054 tCO2e (vs. 2012), a decrease of 493,134 tCO2e* compared to 2017.
*Carbon emissions = Transportation distance x cargo weight x emission coefficient x number of trips
