Pollution Prevention
Air Pollution Prevention and Control
Radiant Opto- Electronics’plants do not produce emissions of nitrogen oxides or sulfur oxides, nor do they emit ozone-depleting substances (ODS). In 2023, all air pollutants met local regulatory requirements. Regular inspections and maintenance are conducted for each facility to ensure optimal operational capability of the equipment. Operators receive comprehensive training to ensure the equipment systems are operated normally and without the risk of emitting hazardous gases.
Prevention and Control of Water Pollution
All factories under Radiant Opto-Electronics Corporation comply with local regulatory standards for effluent. Waste water is discharged into the sewerage system of the respective area for waste water treatment. As a result, no independent sewerage treatment system is established within the factories. In addition, effluent water is regularly tested by the Corporation to ensure that there is no impact on territorial waters.All factories under Radiant Opto-Electronics Corporation comply with local regulatory standards for effluent.

Waste Management
In 2023, Radiant Opto-Electronics has implemented the “Zero Waste to Landfill System (UL 2799)” and integrated waste classification lists from various plants with local regulatory waste code names. After taking inventory of recyclable waste materials at each workstation, we conducted field visits to recycling facilities, confirmed the recycling and disposal processes, and ultimately obtained the “Zero Waste to Landfill Declaration” to track the flow of waste recycling and disposal and improve actual conversion rates.
The Company’s waste output can be divided into two categories: hazardous industrial waste and non-hazardous industrial waste. Statistical data shows that in 2023, the total waste generated was amounted to 4,105.69 tons, a reduction of approximately 29.2% compared to the 5,802.31 tons of waste generated in 2022. In 2023, non-hazardous industrial waste accounted for about 4,060.82 tons, representing 98.9% of the total waste, while hazardous industrial waste totaled approximately 44.87 tons, constituting 1.1% of the waste and being relatively noncomplex in nature.
In terms of waste management categorization, the primary treatment method for nonhazardous industrial waste is “recycling and reuse,”accounting for approximately 2,578 tons, 63.5% of the total. The next most common method is “incineration (excluding energy recovery),” amounting to about 1,208.1390 tons, or 34% of the total. For hazardous industrial waste, “incineration (excluding energy recovery)” is the dominant treatment method, representing approximately 41.4800 tons, or 96.2%. The Company actively promotes waste recycling and converts waste into useful resources. It not only attained recycling resources but also reduced energy consumption and costs associated with waste disposal.
Expenses Related to Environmental Protection
The Corporation has established several pollution prevention and control facilities to effectively manage and control industrial waste and wastewater. At the front end of the production process, we maintain, replace, and add new equipment with the best possible solutions to reduce pollutant emissions during the manufacturing process; at the end of the process, we treat all waste properly to continuously increase the recycling rate. In 2023, approximately NT $ 15,163 was invested in environmental protection, primarily for the purpose of preventing water pollution through sewage treatment fees. The increase in water pollution control costs in 2023 is due to the inclusion of sewage treatment fees for wastewater from the Nanjing plant.
