In line with TSMC’s principle of "minimizing waste, maximizing recycling, and optimizing management", TSMC has continued to advance its recycling and reuse methodologies and increased the waste recycling rate for fabs in Taiwan from 96% to 97% in 2023. As a result, TSMC’s Taiwan fabs became the first semiconductor facilities in the world to jointly obtain the highest platinum rating for UL 2799 certification in October. This achievement builds on the success of Phase one and two of TSMC’s Fab 12 in gaining the UL 2799 platinum certification in 2021. TSMC will continue to strive towards its goal of net-zero emission in 2050 and reaffirm its commitment to the United Nations Sustainable Development Goal 12.

TSMC is deeply committed to its mission of strengthening environmental protection. In addition to a concerted effort by fabs in Taiwan to jointly obtain UL 2799, the highest platinum rating, TSMC joins hands with the supply chain to create a positive circular economy that benefits the entire industry.

Combing Efforts to Obtain Certification and Deepen the Impact of a Circular Economy

TSMC magnifies the impact of its efforts to create a circular economy through four directives: the "Industry Cooperation to Co-create Resources Project, the Action Plan to Turn Waste into High-value Products, the Zero Waste Manufacturing Center, and the Electronic-grade Chemicals Recycling Project". TSMC also practices “Smart Copy”, which also greatly enhances the consistency of sustainability management among various fabs in Taiwan. In 2022, the "UL 2799 Taiwan Fab Joint Certification Plan" was launched to challenge the conventional approach of single factory certification. The effort to combine review items and procedures of various fabs was recognized by UL Solutions and the review process was successfully shortened from three years to nine months.

TSMC has the world's first jointly obtained UL 2799 platinum certification in the semiconductor industry. The highly efficient certification process demonstrates the effort of the TSMC team that set the standard for sustainability and led suppliers to strengthen resource recovery.

Promote Waste Resource Revitalization Projects and Continue to Create a Green Cycle

In order to achieve the goal of zero-waste through innovative recycling and reuse technologies, TSMC has been driving the “Industry Cooperation to Co-create Resources Project” with suppliers since 2020 to take inventory of unrecycled waste in the fabs. The project focuses on large-volume construction waste and quartz parts that are further processed into low-strength concrete, lightweight energy storing bricks, refractory bricks and other materials used by the construction industry. Waste plastics are converted into alternative solid fuel for cogeneration plants to reduce the usage of coal. Borrowing from the successful experience of generating electronic-grade copper materials, quartz discs are processed into quartz rings and returned to the etching process in the fabs.

TSMC is committed to sustainable resource regeneration. In 2024, the Company plans to produce small quantities of molecular sieves, graphite and ceramic consumables for use in other industries, and continues to evaluate anaerobic digestion technology for organic sludge treatment. TSMC is expected to achieve its zero-waste target in 2030. At the same time, TSMC will exert its influence in the industry to share and promote its waste resource management experience.
