Environmental Protection

Air Pollution Management

The Company’s Safety and Health Office is dedicated to prevent all types of air pollution. Waste gases and process exhausts are effectively collected and treated by the most appropriate pollution prevention equipment. The exhausts are tested for compliance with regulations before being released. The main sources of air pollutants are emissions from boiler combustion and process exhausts. The types of pollutants include: particulate matter, sulfur oxides, nitrogen oxides, dust, volatile organic compounds (VOCS), waste heat and odors. For different process exhaust flue, the Company installs prevention and treatment equipments, such as: cyclone dust collector, bag type dust collector, activated carbon adsorption and filling tower, wet scrubber tower, etc.

In 2019, for the waste heat and odor collected in the curing area of the Yuanlin Plant, additional washing towers have been added for treatment before emission. All exhausts must be inspected at the discharge port of exhaust flue in accordance with the regulations. The inspection results must comply with the standards stipulated by regulations.

Water Resources Management

In response to the rapid changed in the environment, extreme rainfall and prolonged droughts that seriously affect people’s quality of life, the Company’s Occupational Safety & Health (OSH) and Environment Committee is dedicated to reduce water consumption by recycling process water and effluents.

Waste Management

The Company’s Safety and Health Office has a standardized storage and treatment plan for general waste and hazardous waste, and will continue to seek efficient ways to recycle and reuse the waste as well as reduce the amount of waste. Through the approved “Business Waste Cleanup Plan” by local environmental authorities, waste is handled by waste clearance companies certified by the authorities. The vehicle of the waste clearance companies is tracked to the final disposal stations to ensure the legal stations for disposal. Waste Disposal Method: General waste is treated by burial and incineration. Hazardous waste is treated by incineration and chemical treatments. Recycled and reused waste such as waste tires will be cracked to produce cracked oil and environmentally-friendly carbon black. The gas generated from the cracking process can be used as fuel in the combustion furnace.
The Company set up improvement projects for each production process to continuously reduce side products and scrap rate, and to minimize the impact on the environment with a target of 10% recycling rate.
