Pollution Prevention

With the philosophy of “contributing to the community” and recognizing “the finite nature of Earth's resources” and “the importance of environmental protection,” CWTC is committed to environmental protection in all aspects including business operations, products and services.

  1. Adopt low-pollution raw materials and clean production methods; commit to environmental protection and reduce the environmental impact of our product supply chain.
  2. Comply with relevant environmental laws and regulations and fulfill the environmental responsibilities of all entities within the CWTC Group.
  3. Continuously improve and enhance environmental performance through environmental target setting, regular audits, and management reviews.
  4. Adopt appropriate risk control techniques to effectively reduce the risk of hazards to stakeholders, and continuously strengthen relationships with contractors and suppliers.
  5. Protect natural resources through programs for efficient use and waste reduction.
  6. Reduce and prevent the environmental impact of harmful substances to protect our employees and the environment.
  7. Improve production quality to reduce waste.

Waste Management

Waste generated by the Company can be categorized into two major types: “non-hazardous industrial waste” and “hazardous industrial waste,” which are further classified into recyclable and non-recyclable waste based on disposal methods. In addition to implementing waste sorting, the Company complies with local regulations for waste reporting, sorting, and storage, and engages qualified vendors to assist in the removal, disposal, and recycling of waste. We ensure that our waste is properly handled through regular vendor reviews and audits. For example, Taiwan Plant No. 2 manages industrial waste online through the "Three-Party Waste Disposal Control and Delivery Form." It also formulates an audit plan for waste clearance and disposal organizations by dispatching personnel to conduct on-site inspections of their management practices, with the audit results recorded in an inspection log. If any irregularities are detected during inspections, the company will notify the contractor to make improvements and schedule a follow-up audit to ensure that the waste is managed in compliance with regulations.

Taiwan Plant No. 2 has been recognized for its excellence in recycling for two consecutive years (2021-2022). The Company will continue to focus on waste reduction at the source, recycling, and reuse as management objectives to minimize waste generation, aiming to reduce operating costs and environmental impact.

Case of Circular Economy - Recycling of precious metal including silver, gold and palladium from waste produced during the manufacturing process

To promote a sustainable environment, CWTC has introduced precious metal recycling technology and established an in-house treatment system to reduce waste emissions. Our main recycling technologies are described as follows:

　　STEP 1: Silver stripping tanks

　　STEP 2: Revive silver stripping plates

　　STEP 3: Silver stripping tanks for plates

　　STEP 4: Precipitation of silver on cathode plates

　　STEP 5: Scrapping of silver precipitated on the cathode plants for collection

　　STEP 6: Filter bags for silver stripping plates

　　STEP 7: Packaging and shipment of silver/filter bags for refinement

　　STEP 8: Made into raw materials (e.g., silver plates) by processors for reuse

　　STEP 1: Silver recovery tank

　　STEP 2: Drums for waste solutions containing silver

　　STEP 3: Electrolytic recovery equipment

　　STEP 4: Dry storage for plated silver

　　STEP 5: SStripping of silver from drums

　　STEP 6: Packaging and shipment of electrolytic silver

　　STEP 7: Made into raw materials (e.g., potassium silver cyanide) by processors for reuse
