Air Pollution Prevention and Control
Air pollution is a pervasive public health issue that transcends borders, resulting in heightened environmental strain and worsened climate change. HIWIN has successfully acquired emission permits for all of its factories and has implemented robust measures to prevent and control air pollution, building upon existing air pollution control practices. In accordance with regulatory mandates, we conduct regular emissions testing, ensuring that all air pollution emissions remain below the standards set by the EPA.
The amount of volatile organic compounds (VOCs) emitted by HIWIN has significantly decreased since 2020. This reduction was achieved by replacing VOCs in our raw materials through adjustments. In 2022, we were able to further reduce the use of raw materials, resulting in a lower emission concentration and a total VOC reduction of 2.86 MT compared to 2021. Additionally, sulfur oxides and nitrogen oxides emissions decreased by 1.21 MT and 2.44 MT respectively in 2022, compared to the previous year.
This reduction can be attributed to the implementation of electric heating in certain process equipment at our factories. Based on our review of the regulations, it is not necessary to calculate sulfur oxides and nitrogen oxides emissions.
HIWIN's preventive equipment is managed by dedicated personnel who regularly outsource monthly maintenance and testing. They also conduct inspections and regular audits internally. The sources of air pollution in our facilities are the process machines and gas boilers listed in the environmental protection regulations. The Headquarters, Jingke Factory 2, Yunlin Factory, and Dapumei Factory are among the factories that require the installation of preventive equipment. Based on the characteristics of our manufacturing process, we have implemented water washing, dust collection, and other air treatment equipment for pre-treatment. Moving forward, we will continue to enhance our existing equipment and treatment efficiency to further increase the reduction rate.
