We use the natural gas-fired boilers for our manufacturing operation; therefore, no sulfur oxide, SOx, air pollutants are generated. But, the particulate matter, PM, created from the production processes were collected and filtered by the cyclone separator before the discharge, and regular emission tests are carried out and monitored. In 2020, particulate matter emissions were 25.15 tons, which was a 7.1% reduction when compared to 26.94 tons discharged in 2019.Nitrogen oxide, NOx, emissions were 3.43 tons, and sulfur oxide, SOx, emissions were 0 tons.
In 2020, 5 air pollution violations occurred. Two of the incidents were the surrounding odor discharge did not meet the regulatory standards of odor emission, a fine of NT$400,000.Two other incidents involved with the malfunctions of preventive equipment which were not remediated in a timely matter; therefore, fined for NT$200,000.The preventive actions taken were purchase odor treatment equipment, a cost of NT$2.58 million, production process equipment upgrades, and the maintenance of cyclone separator, a cost of NT$804,000.
The other violation involved with un-timely reporting of waste disposal. Upon disposal, the reporting of the toxic chemical substances used for inspection was not in a timely manner, a fine of NT$60,000.
