Waste Management
TSC is committed to minimizing environmental impact—particularly from waste—while improving resource efficiency and reducing operational costs. All sites are certified under ISO 14001 and conduct regular internal audits.
To manage waste responsibly, each site classifies on-site resource-type waste and outsources removal, processing, and recycling to licensed vendors. Special waste, such as chemical solvents, is temporarily stored in designated areas and handled by government-approved contractors. To ensure traceability, TSC has established a contractor audit plan that includes on-site inspections, GPS tracking, and a comprehensive vendor management system to strengthen waste control practices.
TSC's Commitment to Waste Management
Waste Statistics
In 2024, TSC generated a total of 2,130.27 metric tons of waste, including 936.73 metric tons (44%) of hazardous industrial waste and 1,193.54 metric tons (56%) of non-hazardous waste. Each production site engages qualified waste clearance and transportation vendors to assist with waste disposal and treatment. Waste statistics for each production site are compiled internally by the site affairs unit and reported on a regular basis. Supporting documents, such as the triplicate waste weighing form, are retained for future reference in accordance with local government regulations.
To enhance waste management practices, the Lije Site has implemented a calcium fluoride sludge reduction program and partnered with designated vendors to recycle waste liquids from the four-inch plant. These waste liquids are fully recycled and reused as raw materials in cement manufacturing. The Yilan Site is working with external vendors to develop reuse mechanisms. The Shandong Site is promoting source reduction initiatives, including a program to replace heat-shrink plastic films,
aiming to reduce raw material usage at the source and, in turn, decrease overall waste generation.
