Environmental Sustainability

Winbond has worked alongside countries and companies from around the world to implement green sustainability measures, proactively reducing the impact that our business operations have on the environment. Apart from having no major violations of environmental laws, Winbond has also committed innovative new technologies and significant resources into adopting measures for reducing energy consumption and carbon emissions, improving resource utilization rates, and improving waste and emissions management, taking concrete action to implement our sustainable development blueprint.

Air Pollution Control

Air Pollution control

Winbond’s air pollution prevention strategy starts with reducing emissions at the source. Process improvementsare used to reduce the amount of pollutants generated to a reasonable level. Pollutants in the missions are thentreated with high-performance control equipment to ensure that atmospheric emissions exceed governmentstandards for pollutant content. All past measurements found that Winbond emissions were all lower than EPAemission standards. 

Emissions from Winbond processes are categorized as acidic, alkaline, volatile organic or general emissionsbased on their attributes. General emissions are mainly hot exhaust from machines which do not cause airpollution. Effective air pollution control equipment is used for each type of pollutant. Winbond has installedlocal scrubber equipment for certain hazardous, flammable, FCs and PFCs emissions from production processes.These emissions go through the absorption and incineration process before being channeled to the centralemission washing tower for washing and neutralization of their inorganic acids and alkaloids. Emissions thatcontain VOCs are sent directly to the zeolite rotor for absorption before being treated by vertical incinerators.Our average removal rate for VOCs were higher than 97% over 10 years and exceeded the relevant EPA regulations.

Our air pollution prevention system can be immediately switched to a backup system in an emergency or during maintenance. They are equipped with emergency power backup systems as well as an advanced real-time monitoring system that tracks changes in the system’s operating parameters 24 hours a day. An alert is immediately sent if a pre-set threshold is exceeded for immediate action to ensure reliable and continuous operations 24 hours a day, 365 days a year.

Our average removal rate for VOCs in 2022 reached 99% and exceeded the relevant EPA regulations.
