Air Pollution Control
The gas emissions in Wistron's production process consist mostly of hot air and tin fumes. They also contain volatile organic compounds (VOCs) from the isopropyl alcohol used for cleaning. According to internal standard procedures, the gas is concentrated and collected in the ducts for the waste gas treatment equipment to absorb before emissions. The Company passes regular waste gas sampling inspections to ensure compliance with regulatory requirements.
The used isopropanol waste liquid is uniformly stored in a specific area, and then handed over to an external qualified processor for cleaning and transportation. Wistron implements inventory and management of substances that contain VOCs to ensure that operators of all positions are equipped with personal protection equipment (PPE) and related ventilation devices in the usage and storage process. These measures ensure health and safety for personnel while reducing the potential negative impact of VOCs on the environment. Nitrogen oxides (NOx) and sulfur oxides (SOx) are only emitted in Wistron Plants when generators are used and fuel is incinerated in the process. The generators are only activated in the event of emergencies (e.g., power outages) and are not regular sources of emissions. Therefore, they are not listed as the main sources of emissions.
