Taiwan Steel Union Co., Ltd. (TSU) has achieved remarkable milestones in environmental protection and sustainable development, winning the Bronze Award at the 8th National Enterprise Environmental Protection Awards on the 2nd of this month. Chairman Lin Tsai-hsiang and fellow award-winning representatives were invited to the Presidential Office to be personally commended by President Lai Ching-te. Meanwhile, General Manager Hsieh Tsung-lin received the honor directly from Minister of Environment Peng Chi-ming at the Ministry of Environment, highlighting national recognition of the company’s dedicated green operations.

Guided by its core principles of “resource circularity, low-carbon processes, zero waste, and zero landfill,” Taiwan Steel Union has long focused on the treatment and high-value reuse of hazardous industrial waste, such as electric arc furnace (EAF) dust, successfully establishing a vital “zinc metal life-cycle loop” within the steel scrap circular economy. This national environmental distinction is backed by the following key achievements:

• Energy & Resource Circularity and Low-Carbon Transformation: The company expanded the reuse of 11 types of waste across three major categories as alternative raw materials and fuels. Compared to 2012, greenhouse gas (GHG) emissions have dropped by 35%, while product yield has increased by 10%. Concurrently, renewable energy adoption has reached 32%. Combined with high-efficiency equipment upgrades, total electricity savings in 2025 reached 2.18 million kWh, cutting approximately 1,033 metric tons of GHG emissions. In addition, the recycling rate of hazardous slag reached 100%, fully converting it into recycled aggregates for industrial use.
• Pioneering Pollution Prevention and Water Resource Management: TSU pioneered the nation’s first “Five-Stage BACT (Best Available Control Technology) Air Pollution Control System,” achieving a heavy metal removal efficiency exceeding 99.9% and keeping emissions well below statutory thresholds. The entire plant utilizes a closed-loop wastewater management system, prioritizing reuse for process pelletizing and dust suppression, thereby maintaining high water reclamation rates.
• Green Technology Export and International Reach: Exporting its proprietary low-carbon smelting technology abroad, TSU successfully assisted a Polish client in reducing coke consumption by 30% and eliminating 100% of natural gas usage—achieving a 25% overall carbon reduction and demonstrating the global competitiveness of Taiwan’s circular economy and low-carbon engineering.
• Social Inclusion and Community Engagement: TSU institutionalized good-neighbor practices, implemented green procurement, organized coastal cleanups to protect local shorelines, and provided long-term support for local cultural development, youth sports, and circular economy education. In 2025, total social welfare expenditures exceeded NT$17.27 million, fulfilling the company’s commitment to corporate citizenship.

Chairman Lin Tsai-hsiang noted that receiving the National Enterprise Environmental Protection Award and being received by the President serves as the greatest encouragement for all employees’ sustained commitment to sustainability. Looking ahead, Taiwan Steel Union will continue to advance its core resource recovery technologies, broaden waste reuse applications, and strengthen domestic and global low-carbon circular economy networks. While maintaining steady operations, the company will partner with industry, local communities, and society toward a sustainable, net-zero green future.
