To pursue environmental sustainability, NTC followed the policy of Formosa Plastics Group in August, 2008, applied Environmental Accounting System in October, 2009, and implemented this technique officially in 2010. Through this strategy, NTC is able to measure resource use, evaluate environmental cost, and disclose to stakeholders properly. The most notable changes from 2011 to 2015 is per use of each wafer the water usage per square meter decreased by 20% from 52.1 tons to 41.7 tons and the electricity usage decreased from 8.7 mWH to 7.8 mWH.
Used water 3m3/water is 12.3% lower than 2014.
The power consumption per wafer is 7.77KWH/wafer, 7.3% lower than 2014.
The Greenhouse gas (PFCs) is reduced 286,034 ton CO2-e which equals to one year CO2 absorption quantity of 773 dimensions of Da-an Park.
The occupational injury rate has been 0 for the past three years.
Air Pollution Control: NTC always concerns about the pollution prevention and keeps working on the environmental management system (ISO 14001), which includes reducing the raw material and the air pollution exhaust. NTC use air pollution control equipments, including local scrubbers, acid/alkali central scrubbers, VOCs Fluidized bed system and Rotor Concentrator & Thermal Oxidizer; The VOCs emission intensity of each unit product in 2015 was 0.23 (kg VOCs/m2).
Water Pollution Control: NTC classifies waste water based on the characters of waste water for different treatment facilities in order to follow the environmental protection regulation, and reclaims acid/alkali waste water through reclamation treatment system to reduce waste water effluence. NTC plans to expand organic waste water reclamation system which can reduce 1,000 tons/day waste water effluence in 2016.
Waste Management: NTC Fab-3A’s waste was 9785.05 tons in 2015, in which the amount of general waste was 4693.42 tons, hazardous waste are 5091.63 tons, waste recycling was about 95%. [Learn More]
NTC FAB-3A achieves processing water recycle ratio 86% through building reclaimed water system for acid/base waste water and conducting water savings activities. The power consumption per square meter of wafer decreases 0.6 MWh/M2 (decreased by 7.1% from 2014 to 2015). [Learn More]
Perfluorocarbons (PFCs) and Electric power are the main sources of emissions from semiconductor factory. From 2008 to 2015, GHG emissions has been increased by 47.74% and the product output has been increased by 138.76% in NTC Fab-3A. However, GHG emissions intensity was 38.12% less from 2008 to 2015 and it was the cause of our efforts in the GHG reduction programs of 2015 t will be saved about 2854 kw/hr of electricity power and 300 m3 of natural gas every day.
Since 2005, NTC has established the Green Product Promotion Committee (GPPC) to follow Hazardous Substances Process Management (HSPM). NTC targets pollution prevention, economization of energy sources, reduction of wastes and hazardous substance control and management, and actively connects with our suppliers and subcontractors from raw materials of processes to assembly production and packing of shipment to make an efficient supplier chain of eco-friendly products. The goal is to meet current laws and regulations and reduce environmental expenses during the production process. [Learn More]
In 2015, the total environmental expenditure was NT$ 360,483 thousands and the total environmental capital expenditure was NT$ 91,006 thousands, and the summary environmental fee was NT$ 451,489 thousands. [Learn More]
