Waste Management
Each of our sites follows the ISO 14001 framework to manage waste from source to disposal. Since 2022, we have implemented a Waste Reduction Policy to drive ongoing reduction efforts. From the design stage, we prioritize material selection and minimalism to reduce waste generation. During production, we optimize processes to improve material efficiency, reduce scraps and defects, and minimize hazardous substances. We ensure legal waste handling through qualified vendors and actively promote recycling and resale to extend material lifespan and maximize resource circulation.
In 2024, our total waste amounted to 6,228.49 metric tons, a 6.48% increase from 2023. Waste intensity reached 0.101 tons per NT$1 million revenue, up 2.02%. The rise was mainly due to business expansion and product mix changes, leading to an increase of about 370 tons of hazardous waste. We continue to strengthen waste control and minimize negative impacts from operations. All sites strictly manage hazardous waste and audit each disposal vendor at least once. No violations were found, aligning with our Waste Reduction Policy.

Notes:
- Scope of Data: HQ, Major Production Bases. The subsidiary companies, Chicony Power and XAVI, can refer to the sustainability reports of the two subsidiaries for their data. The coverage of the disclosed data based on consolidated revenue calculations is 99%.
- This table adopts a disclosure framework different from that used in 2023, in alignment with the company’s implementation of UL 2799A certification procedures.
- Total Recyclable / Reusable Waste = Reuse + Recycle + Recyclable and Reusable
- Total Recyclable / Reusable Waste (Rate) = (Reuse + Recycle + Recyclable and Reusable) ÷ Total Waste
- (Hazardous and Non-Hazardous) Waste intensity = (Hazardous and Non-Hazardous) Total Waste ÷ Consolidated revenue (Consolidated group revenue excluding revenues from CP
and XAVI); Unit: Metric tons/NT$1,000,000.

Notes:
- Scope of Data Covers Major Production Bases.
- Due to data incompleteness, the recirculation percentage cannot be disclosed for the time being.
Since 2022, the Company has adopted its CET as a demonstration site for the first-time implementation of the UL 2799A Environmental Claim Validation Procedure (ECVP) for Zero Waste Classification. By 2024, both the CET and CEM5 have obtained UL 2799A Platinum certification with a diversion rate of 100%. Other major production bases are expected to obtain certification by 2025, with an anticipated diversion rate of over 90% across all production bases, meeting the Silver level standard.
In addition, we continuously promote awareness among plant employees through education and training to ensure proper waste sorting and reduce the generation of domestic waste. We also collaborate with our value chain partners to effectively utilize valuable waste and discarded materials, achieving a total recycling value of NT$11.08 million. We also make good use of factory resources by reusing discarded uniforms from the factories. After cleaning and organizing them, the uniforms are distributed to employees in need, promoting both sustainable resource circulation and a cycle of goodwill.
Factory personnel provide guidance on waste sorting.
Air Pollution Management
The gas emissions generated during CEC's production processes primarily originate from ink printing, dispensing, injection molding, and SMT operations. The main emissions include heat, solder fumes, and a portion of volatile organic compounds (VOCs). In accordance with internal standard procedures, all gases are centrally collected through pipelines and treated using exhaust gas treatment equipment before being discharged into the external environment. CEC's facilities are equipped with air pollution control systems with removal efficiency exceeding 90%, including activated carbon adsorption and electrostatic precipitation technologies. These systems effectively reduce pollutant emissions and ensure compliance with environmental regulations.
In addition, CEC conducts thorough inventories and implements strict controls over substances containing VOCs. The company ensures that all relevant personnel are equipped with appropriate personal protective equipment (PPE) and that proper exhaust systems are in place during usage and storage, safeguarding operational safety and minimizing the environmental impact of VOCs.
All CEC manufacturing factories comply with local environmental regulations and have obtained the required air pollutant emission permits. Regular air pollution monitoring is conducted at each site. In 2024, the estimated total air pollutant emissions included 4.84 metric tons of volatile organic compounds (VOCs) and 0.28 metric tons of particulate matter (PM), which remained roughly consistent with 2023 levels.
Notes:
- The emissions of hazardous air pollutants (HAP), perfluorocarbons (PFC), persistent organicpollutants (POP), and ozone-depleting substances (ODS) are all 0 metric tons.
- Nitrogen oxides (NOx) and sulfur oxides (SOx) primarily originate from the combustion of diesel in generators. However, generators are only activated in emergency situations, such as during power outages, and are considered non-routine emission sources; therefore, they are not classified as major sources of emissions.
