Waste and Hazardous Substance Management
The Company is committed to environmental protection and has set a target to increase its waste diversion rate to over 99% by 2025. The Sustainable Development Committee conducts annual performance reviews and regularly carries out internal and external audits. All types of waste at GIS are legally sorted and placed in designated temporary storage areas, and licensed, professional waste disposal contractors are engaged to perform recycling, reuse, or appropriate clearance and disposal, in accordance with regulations from the national fire agency, central environmental protection authorities, and the Ministry of Environment. Final disposal of all waste is periodically tracked and audited by responsible departments to ensure legality and safety.
In 2025, the GIS Shenzhen Factory once again received the UL2799 Zero Waste to Landfill – Platinum Certification, the highest level of recognition, with the certificate validity period until March 15, 2026.
Additionally, to achieve standardized, digitalized, and visualized management, the Company developed an online "Corporate Waste Management System" in 2025, effectively integrating waste information from the Chengdu, Shenzhen, and Taiwan factories to enhance operational efficiency and establish a systematic management framework.
Waste Disposal Process
Hazard Determination and Identification
In accordance with the Waste Management Operation Specifications of GIS, the Company conducts hazard determinations and classifications of waste during the environmental impact assessment stage based on factors such as waste name, composition, and annual generation volume. Identified hazardous waste must be stored in compliance with regulations. Waste classification is as follows:
Non-hazardous waste：Packaging materials from upstream transportation stages, waste glass scraps and miscellaneous items generated during production, as well as general household and kitchen waste.
Hazardous waste：Includes sludge, organic wipes/cotton swabs, cleaning agents, and organic solvents, etc.
Total Waste
According to statistics, the total weight of waste generated by the Company in 2025 was 12,533.73metric tons, a decrease of 1.26% compared with 2024 (12694.58metric tons). All waste was disposed of off-site. As non-hazardous waste accounts for the majority of GIS's total waste, the Company is dedicated to reducing it by increasing the recycling rate and adjusting raw material packaging, such as reusingpallets, packaging bags, and trays.
Total Hazardous/Non-Hazardous Waste at GIS
Improve waste diversion rates
To achieve resource sustainability, our company prioritizes on-site reuse in waste management, reducing raw material use and minimizing the use of energy-saving incineration/landfilling methods. to improve the diversion rate of Non-Hazardous Waste, the Chengdu Factory adopted effective recycling measures in 2025, similar to the Shenzhen Factory's approach, by categorizing and recycling waste glass to reduce landfill volume. The diversion rate increased from 30% to 100%, with a total of 2.33 metric tons processed in 2025. The waste glass output from the Taiwan Factories includes composite materials. In 2026, arrangements have been made with a vendor capable of processing composite glass, and it is expected that the waste diversion rate will continue to improve in 2026.The recycling projects implemented in 2025 are as follows:

The 2025 GIS waste treatment improvement data are as follows:
• Incineration (including energy recovery) accounted for 15.54%, a decrease of 0.82% from 2024 (16.36%).
• Landfill accounted for 0.03%, a decrease of 0.43% from 2024 (0.46%) • Recycle and Reuse accounted for 82.51%, an increase of 1.35% from 2024 (81.16%).
• Anaerobic digestion accounted for 0.94%, an increase of 0.94% from 2024 (0%).
• Waste heat recovery accounted for 0.10%, an increase of 0.10% from 2024 (0%).
Hazardous Substance Control Policy
GIS ensures a sound hazardous substance management system by monitoring and improving it. Combining this with risk and opportunity management, GIS continues to provide non-toxic, green, and environmentally friendly products, creating competitiveness for GIS in green products while fulfilling its sustainable operations.

QC080000 Hazardous Substances Process Management System
GIS implemented the QC080000 Hazardous Substances Process Management System in 2012 and obtained certification from a third-party notary public. In 2025, GIS once again completed the system transition audit and obtained the updated certification.
All products are 100% compliant with international safety and environmental regulations (including RoHS, WEEE, HF, REACH, etc.). GIS has also established a GP team responsible for managing its hazardous substances system.
GIS Controlled Substances Handling Specifications
Since 2011, GIS has revised its Controlled Substances Handling Specifications 17 times (as of the end of 2025) to ensure that all products and materials comply with the latest regulatory requirements. In 2025, the company, in accordance with internal regulations, identified hazardous substances and implemented a tiered management system (Level 1, Level 2, and Level 3). There are 62 major categories of controlled substances, with stakeholders requesting additional control for 387 items, resulting in over 900 substances actually being controlled. To address changes in legal requirements, such as the EU REACH Regulation, the company promptly updates its Controlled Substances Handling Specifications and meticulously manages each update.
Supplier Traceability System
To ensure 100% product compliance with green standards, GIS enforces stringent supplier management. All raw materials must undergo traceability procedures under “the Company's Green Product Management Operating System prior to procurement”. Using the Supplier Traceability System (Green Component System, GCS), GIS investigates data on first-tier and second-tier (or lower) suppliers, including information related to REACH, SVHC, conflict minerals, VOCs, and specific restricted substances. Collected data covers the type, model, manufacturer, country of origin, and chemical composition (by percentage) for each homogeneous material within every component. Only materials verified as compliant through internal audits may proceed to procurement. Additionally, GIS requires suppliers to sign a Supplier Commitment Letter (including environmental assurance clauses) and stipulates in contracts that raw material packaging must include hazardous substance labeling. Suppliers must declare the substance composition of all raw materials. In 2025, GIS completed approximately 400 declaration form reviews covering nearly 11 product models. For chemicals or substances requested by stakeholders, suppliers are required to provide a Safety Data Sheet (SDS), which must be posted in designated chemical usage areas within the facility to warn and inform operational personnel.
