Venue: Kaohsiung Exhibition Center

Taiwan’s leading environmental protection and waste management enterprise, Taiwan Steel Union Co., Ltd. (Stock Code: 6581), along with its subsidiary Taiwan Steel Resources, officially commenced their joint exhibition today at the grand opening of the “2026 Kaohsiung Smart City Summit & Expo” held at the Kaohsiung Exhibition Center. The exhibition closely aligns with the event’s core themes of “Digital and Green Twin Transition” and “Net-Zero Sustainability,” comprehensively demonstrating the affiliated companies’ profound strength in the circular economy, as well as their recent active deployment of the “Low-Carbon Smart Operations Platform.”

In response to global climate change and the trend toward net-zero carbon emissions, TSU continues to deepen its waste-to-resource technology. Through vertical integration within its affiliated companies, TSU focuses on extracting crude zinc oxide from EAF dust, zinc-containing waste and zinc products. Meanwhile, TSR is dedicated to transforming industrial waste—such as reduced slag, rotary kiln slag, co-combustion ash, and waste refractory materials—into high-value-added green building materials. The synergistic operation of both parties not only effectively resolves the disposal issues of domestic industrial waste but also successfully creates a complete “waste-to-resource” closed loop, setting a benchmark for Taiwan’s circular economy.

To further enhance productivity and expand waste treatment capacity, TSU is introducing its “Low-Carbon Smart Operations Platform” at this exhibition. By integrating the Artificial Intelligence of Things (AIoT) and data analytics, the platform features the following three core highlights:

• Real-time Process Monitoring and Optimization: Through data collection and visual management, the platform precisely monitors energy consumption and equipment operation status across all plants, effectively improving processing efficiency and reducing unnecessary energy consumption.

• Carbon Emission Tracking and Transparency: Utilizing a carbon management system to systematically record carbon emission data, it assists enterprises in implementing strict corporate governance and ESG information disclosure, meeting the stringent low-carbon standards of domestic and international supply chains.

• Data-Driven Decision Support: By integrating information from front-end material intake and production processes to back-end sales, the platform provides management with real-time, data-backed support.

Sean Lin , Chairman of TSU, stated: “Implementing a circular economy relies not solely on concepts, but requires the assistance of practical technology and digital tools. Through the Kaohsiung Smart City Expo, we hope to share with all sectors our practical application cases that combine ‘digital management’ and ‘green manufacturing processes.’ This is not only our commitment to environmental sustainability but also an important driving force for promoting the company’s long-term revenue growth and creating a win-win situation for both our shareholders and society.”
