TSMC, the world's largest contract chipmaker, is highlighting the ecological dividends of its long-term sustainability initiatives in Taiwan—ranging from improved biodiversity to branded honey.

At the 2025 Asia Pacific Sustainability Expo – Co-Prosperity x Growth Forum on Friday, Ho Li-mei, TSMC's Senior Vice President of Corporate Sustainability, said the company's efforts in ecological integration have yielded “valuable and sometimes surprising results.”

A standout example is the return of bees to areas around TSMC's fabs following the restoration of native plant species. Partnering with local beekeepers and Tunghai University, the company has launched “Ji Mi,” a TSMC-branded honey product symbolizing the link between advanced manufacturing and ecological balance.

Other indicators of ecosystem recovery include the reappearance of native Taiwanese species such as the silver goby in nearby waters and even fireflies on TSMC sites—making the company the first semiconductor maker in Taiwan to attract the insect, known for its sensitivity to environmental conditions.

Beyond biodiversity, TSMC reported significant progress in resource efficiency. The firm said water recycling rates at its new facilities now exceed 90%, addressing the heavy water demands of semiconductor manufacturing in resource-constrained Taiwan. Meanwhile, TSMC's waste recycling rate has reached 97%, with less than 1% of waste sent to landfills locally. Its “Zero Waste Center” in Taichung is also converting manufacturing waste into electronic-grade raw materials, advancing the circular economy.

With initiatives spanning ecological restoration and industrial recycling, TSMC is positioning sustainability as a core pillar of its global leadership in semiconductors.
