Waste management plan
Winbond adheres to the "Safety, Health, and Environmental Policy" commitment, aiming to "implement environmental protection and reduce environmental, safety, health, and asset risks" in waste management. The waste management strategy is "minimizing waste treatment and maximizing resource recycling," through source reduction, strengthening waste recycling and reuse, and reducing the environmental burden of production.
- Identifying waste reduction hotspots: Identifying key links in the production process that generate large amounts of waste and continuously seeking opportunities for internal waste reduction or recycling.
- Waste reduction actions: Reducing or reusing and increasing recycling rates to minimize the amount of waste generated within the fab, aiming to minimize environmental impact and pollution.
- Quantifying waste reduction targets: The long-term goal of waste management is to achieve an annual waste recycling rate of over 90% in Taiwan fabs by 2030.
Developing new waste reduction technologies: Winbond conducts research, procurement, production, operations, and services based on the following principles to reduce the harm and impact of the company's operations on the natural environment and humans:
- Reducing resource and energy consumption in products and services
- Reducing the emission of pollutants, toxins, and waste, and properly handling waste
- Enhancing the recyclability and reuse of raw materials or products
- Maximizing the sustainable use of renewable resources - Extending the durability of products
- Increasing the efficiency of products and services
- Sustainable culture: Establishing a culture of environmental protection responsibility among all employees, providing environmental education and training to management, employees, suppliers/contractors, expanding value chain cooperation and sharing, and enhancing the awareness and responsibility of internal and external stakeholders for environmental sustainability, exerting social influence, and creating a better sustainable environment.
- Comprehensive recycling and zero landfill: Promoting comprehensive recycling plans to minimize waste landfill treatment.
- Independent certification conversion rate: Aiming for third-party certification to ensure the reliability of waste recycling, reuse, or incineration conversion data.
