Green Commitment．Sustainable Environment

Environmental sustainability is our company's green commitment. We follow the strategy of "implementing energy saving and carbon reduction, building a green home, and strengthening ecological education" to achieve sustainable development. We have set short-, medium-, and long-term goals by planning for each stage of the product lifecycle, including raw material procurement, manufacturing, transportation and distribution, product usage, and final disposal. We specifically incorporate energy saving, carbon reduction, and environmental issues into our business plans and have established internal codes of environmental conduct.

Energy Management

Energy consumption is the main factor causing climate change, because burning non-renewable fuels will produce greenhouse gases (GHG) and cause other environmental impacts. With the steady growth of the Company's operation, we are cautious in improving the efficiency of energy use, controlling greenhouse gas emissions, effectively reducing the per capita energy consumption intensity and avoiding the increase of oil and electricity consumption.

Water resources management

The Company factory is located in Suao Town, Yilan County, with an annual rainfall of more than 2,000 mm. According to the Aqueduct Water Risk Atlas of the World Resources Institute, it is located in a low-risk area of water resources. At present, the process water of Suao Main Plant still uses groundwater. Although there are abundant groundwater resources in Yilan, we continue to actively save and make good use of water resources. In addition to setting up a cooling water recovery system, the non-contact cooling water of the process is recovered, cooled and reused, and the improvement is actively evaluated to reduce the water consumption of the process. Make good use of the recovered cooling water to spray water on the dump, roads, turf and greening plants, so as to make the water resources multi-purpose. the Company's water consumption statistics and wastewater treatment methods are as follows:

Analysis of discharge water

Sesoda's water discharge strictly abides by the discharge water standard of the chemical industry. During this reporting period, the wastewater discharge situation is shown in the following table, and all the data are within the standard. Therefore, it can be seen that the Company monitors the discharge water properly.

Waste management

The Company's wastes are all non-hazardous wastes, and the operation mode of source management is adopted. The sources are divided into two categories: employees' domestic wastes and business wastes, which are entrusted to the legal removal company for departure disposal. Through employee education and training, improve employee behavior norms to achieve domestic waste management, effectively promote reduction and classification management, and improve resource reuse and resource regeneration value; The management of enterprise waste is to simplify the packaging materials, reduce the proportion of waste and recycle resources.

The waste generated by Suao Main Plant is primarily inorganic sludge, accounting for approximately 94.5% of the total. According to the provisions of the Waste Cleaning Law, the purpose is to classify waste during collection, storage, and classification. All units should centralize the waste in designated storage areas and appoint special personnel for the management and planning of waste reduction and access control. Additionally, the treatment process must comply with relevant laws and regulations concerning environmental protection. During the reporting period, there was no serious leakage.

Suao Plant Waste Statistics Table

Due to increased production of certain items at Southeast Industrial’s Suao Plant this year and the absence of scrap iron generation in 2023, total waste volume has significantly exceeded last year’s level. Relevant waste will be closely monitored to achieve the targeted annual reduction. Data is shown in the table below:

Greenhouse gas management

The increase in greenhouse gas emissions leads to climate change, which not only directly impacts the global ecological environment, but also indirectly affects the acquisition of enterprise resources, and has become an environmental issue of common concern and attention all over the world. In order to fulfill the responsibility of the enterprise, the Company identifies the sources of greenhouse gas emissions, reduces greenhouse gas emissions by means of energy saving and emission reduction, and makes active efforts to move toward a low-carbon and sustainable home together by improving self-management ability, replacing high-energy-consuming process equipment and discussing greenhouse gas reduction schemes.

Continuous improvement of energy saving and carbon reduction

In order to reduce the impact of the production process on the environment, improve the competitiveness of products, and better fulfill corporate social responsibilities, the Company clearly classifies and tracks all types of environmental protection expenditures. This control is helpful for evaluating the implementation efficiency of environmental protection measures and conducting internal cost-benefit analyzes.

In 2024, the Company incurred a total of NT$117,546 thousand in various environmental expenditures and costs. These funds were primarily allocated to support pollution prevention and environmental improvement initiatives, including measures targeting air quality, water resources, and waste management across operational sites.
