TSMC inaugurated its zero-waste manufacturing center in Taichung on November 13, while signing a memorandum of understanding (MOU) with Taiwan's Environmental Protection Administration (EPA) to develop advanced carbon capture technology.
The launch ceremony attracted key green technology partners, including Chang Chun Petrochemical Group (CCPG), Transcene Corp., and Liying Environmental Protection Technology, along with representatives from TSMC's supply chain, academia, industry associations, and government officials, marking a significant step forward in sustainable manufacturing.
The Taichung zero-waste manufacturing center functions as TSMC's first demonstration site for circular economy practices. Designed to maximize waste reduction while minimizing environmental impact and risks, the center features four core recycling facilities that process calcium fluoride (CaF₂) sludge, silicon dioxide (SiO₂) sludge, organic solvents (such as acetone C₃H₆O or ethanol C₂H₅OH), and isopropanol (C₃H₈O).
Since beginning trial operations in 2023, the center's purified recycled chemicals have consistently met industry standards, enabling cross-sector reuse. The facility aims to develop electronics-grade recycled chemicals for semiconductor manufacturing, thereby reducing raw material dependence and establishing a circular economy model.
At full capacity, the center is expected to reduce outsourced waste disposal by 130,000 metric tons annually, handling over 85% of the waste produced by TSMC's Central Taiwan Science Park facilities.
Environmental impact studies indicate annual savings of NT$1.5 billion (approx. US$46.5 million), with a carbon reduction equivalent to 40,000 metric tons—comparable to the yearly carbon sequestration of approximately 65 Central Parks in New York or 220 Hyde Parks in London.
Additionally, the Taichung zero-waste center serves as Taiwan's first demonstration site for membrane carbon capture technology. Through the MOU with the EPA, TSMC will jointly develop membrane carbon capture technology for deployment in general waste incineration facilities, furthering its innovative carbon reduction initiatives.
The center showcases green building features, including rainwater recycling and solar power. TSMC plans to replicate this model across its domestic and international sites, supporting UN Sustainable Development Goal 12 and expanding its ESG impact.
