Annual performance

The Company has continued to demonstrate a strong commitment to environmental management and sustainable governance, responding to global climate action demands with tangible results. During the year, the Company conducted a comprehensive group-wide greenhouse gas inventory and obtained external third-party verification, ensuring data transparency and reliability, and laying a solid foundation for the formulation of subsequent carbon reduction strategies and performance tracking.

In terms of energy transition, the group-wide proportion of green electricity usage increased to 43.94%, with a total of 21.05 million kWh of renewable energy adopted, effectively reducing the Company’s operational carbon footprint and supporting the development of the renewable energy market. Water resource management also achieved measurable results: compared with the 2022 baseline year, total group-wide water withdrawal decreased by 22.29 million liters, representing an approximately 27% reduction of water use intensity, reflecting the Company’s continuous efforts to enhance process efficiency and water recycling and reuse. In addition, compared with the baseline year, group-wide Scope 1 and Scope 2 greenhouse gas emissions were reduced by 9,872 metric tons of CO₂-equivalent, a reduction of as much as 40%, demonstrating significant achievements through the adoption of energy-saving technologies, equipment improvements, and the use of green electricity.

The Company also continues to maintain IECQ QC 080000 certification, demonstrating high standards in hazardous substance management and the implementation of comprehensive controls across design, procurement, and manufacturing processes. Overall, through systematic management and continuous innovation, the Company is steadily advancing the reduction of its environmental footprint and taking more resilient steps toward sustainable operations.

As resource depletion and environmental pollution become increasingly severe, waste management and waste reduction have become important issues in global sustainable development. Starting from the source of operations, the Company combines process management with systematic controls to promote waste reduction and resource reuse, striving to reduce environmental impacts while enhancing overall operational efficiency and resource utilization.

To strengthen its management mechanism, each operating site has established waste management procedures in accordance with the environmental management system, regularly tracks waste sources, generation volumes, and final destinations, and uses data inventory and analysis as the basis for continuous improvement. All waste is classified, stored, and hauled in accordance with applicable requirements and is entrusted to qualified treatment organizations for disposal through reuse, incineration, landfill, or other appropriate methods. At the same time, the Company conducts regular audits of treatment contractors to ensure that treatment processes comply with regulatory requirements and reduce environmental risks. In 2025, audits of waste hauling and treatment organizations were completed in accordance with relevant procedures, no deficiencies were identified, and no waste-related violations or penalties occurred during the year.


Waste reduction and management are primarily implemented through the following measures:

Source reduction

Process optimization

Classification and resource reuse

Compliant treatment and audit management

Supply chain collaboration


By introducing waste data management and performance tracking mechanisms, the Company continuously monitors the treatment methods of various types of waste, such as reuse, incineration, and landfill, as well as their respective proportions, using this information as the basis for management improvement and waste reduction efforts. Going forward, it will continue to strengthen resource utilization, reduce the proportions of incineration and landfill, and move toward the goals of increasing recycling rates and reducing waste generation, thereby progressively realizing resource circularity and environmental sustainability.

Waste Management Policy

To implement the goals of waste reduction and resource circularity, the Company has established a comprehensive waste management policy. From source reduction and process management to end-of-pipe treatment, it comprehensively strengthens its waste management mechanisms, striving to reduce environmental impacts and improve resource efficiency while continuing to align with international trends and promote the development of the circular economy.

Its overall management strategy is primarily advanced through the following three key pillars:


  • Source Reduction and Process Optimization

    • Introduce waste reduction thinking at the product design and process planning stages to reduce raw material consumption and defective product generation.
    • For high-risk processes, continuously optimize material selection and process conditions to reduce the use of hazardous substances and waste generation.
  • Classification, Recycling, and Resource Reuse

    • Implement complete recycle systems at all plants and office locations to separately collect and recycle resources such as metals, plastics, paper, and packaging materials.
    • Promote mechanisms for the "reuse, recycling, and reutilization" of waste:
      1. Reuse: Actively collaborate with suppliers to promote the reuse of packaging materials, pallets, and other items, thereby reducing one-time resource consumption.
      2. Recycling: Increase the recycling rate of recyclable waste and reduce the amount requiring final disposal.
      3. Reutilization: Convert waste into reusable resources to enhance resource value.
  • Compliant Treatment and Circular Management

    • All types of waste are properly classified and temporarily stored according to their characteristics and are entrusted to qualified hauling and treatment organizations for subsequent disposal.
    • Establish a tracking mechanism for waste flows from generation to final disposal and conduct regular audits to ensure compliance throughout the treatment process.
    • Continuously evaluate and implement the best feasible resource recovery and waste reduction measures to reduce the proportions of incineration and landfill and enhance resource recovery performance.

In terms of management targets, the Company uses the "waste generation index" as its primary performance indicator, continuously advances waste reduction management, and lowers the waste generation index year by year. It aims to achieve a 1.9% reduction by 2030 in order to improve resource efficiency and reduce environmental burdens.

Going forward, the Company will continue to use data-driven management and performance tracking mechanisms to dynamically review the effectiveness of its waste reduction measures and, together with supply chain collaboration and technological optimization, progressively strengthen resource circularity and move toward the goals of low-waste operations and sustainable management
