- Environmental Management
Radiant Opto-Electronics always upholds to the belief of "sustainable coexistence of the environment". While establishing and operating a sound environmental management system, we also carefully assess the impact of our operations on the environment. Overall, Radiant Opto-Electronics hopes to leverage the power of green manufacturing and create opportunities for sustainable development.
Energy Resource Management
Electricity Structure
In 2023, the primary source of energy used by Radiant Opto-Electronics was purchased electricity, accounting for 98.9% of the Company’s total energy consumption. Additionally, natural gas, gasoline and diesel were used, but their consumption was very low, each constituting less than 0.05% of the total energy consumption. Specifically, the electricity usage was 124,918.8 MWh, and natural gas usage was 72.5 MWh. Moreover, starting in 2024, the Company plans to begin purchasing renewable energy, although no renewable energy was purchased in 2023.
Radiant Opto-Electronics has fully installed solar photovoltaic systems at its production bases in Mainland China, with a total installed capacity reaching 3,562 kW. Among these, the Wujiang plant has the highest generation capacity of 1,762 kW, with an annual total electricity generation of approximately 3.295 million kWh (11,861 GJ). In 2023, renewable energy (solar power) accounted for about 2.6% of the total electricity consumption across the entire group. Radiant Opto-Electronics also coordinates and plans various energy-saving schemes through its Equipment Department, tailoring strategies to the specific manufacturing processes of each plant.
In January 2024, the Kaohsiung factory carried out a UV-LED module renovation project with a cost of approximately 1.41 million to improve power usage efficiency, and cumulatively reduced carbon emissions by approximately 18.74 tons by October.
Usage of Natural Gas
Utilizes natural gas for employees’dormitories to heat the hot water boiler in employees’dormitories. Since 2017, a heat recovery system has been implemented to recycle the waste heat produced by the air compressor and in 2023, a total of 16,196 degrees of natural gas (14,079 joules) was saved through this system. The carbon reduction benefit of this project is approximately 421 tonnes of CO2e.
Water Resources Management
In recent years, due to intensified climate change, the frequency and severity of extreme weather disasters have increased more than ever before, making water resource management a critical issue for corporate operations. However, Radiant Opto-Electronics does not have processes that consume large amounts of water. The primary uses of water are for domestic purposes and air conditioning equipment, and the Group is located in processing export zones or development areas where the water source is third-party water (tap water). There is no use of surface water, groundwater, seawater, or produced water, and since these locations are not under water stress, the environmental impact is relatively low. Nevertheless, Radiant Opto-Electronics continues to enhance awareness and promote water conservation among its employees, emphasizing the importance of valuing and saving water resources.
Statistics showed that the Group’s third-party water usage (tap water) in 2023 was approximately 1,256.5 million liters, saving 27.3 million liters of water. Compared to 2018 (the base year for the 2025 sustainable development goals), the cost of water resource usage for the Group’s energy resources decreased by 40.6%. In 2023, the Kaohsiung plant had a water usage of 44.5 million liters for industrial and domestic purposes. Since 2020, Radiant Opto-Electronics has collaborated with several brand clients to manage water resources at production bases. This involves regular monitoring of water usage at each factory, including assessments of water purification projects and the establishment of water resource management systems.
Energy Policy
"Energy conservation and low carbon" has always been a core belief at Radiant Opto-Electronics. In addition to establishing and operating a comprehensive energy management system, the company also carefully evaluates the impact of its operations on energy consumption. Overall, Radiant Opto-Electronics aims to leverage the power of green manufacturing to create opportunities for sustainable development.
