The Planning, Design, and Strategies for Tai-Chung Zero Waste Manufacturing
Center

│Stephen Chang│Taichung Facility│

Abstract

To overcome the challenges of climate changes, limited resources, and population growth, TSMC has committed
collectively to develop circular economy to reuse resources endlessly and to move away from linear model by building Zero
Waste Manufacturing(ZWM) center in Taichung as the first step. Tai-Chung Zero Waste Manufacturing(TCZWM) Center will
have six ZWM plants with the central utility plant(CUP). The six ZWM plants are Sulfuric Acid Regeneration Plant(SARP), IPA
Regeneration Plant(IRP), Ammonia Regeneration Plant(ARP), Silica Recycling Plant(SRP), Fluoride Recycling Plant(FRP), and
Solvent Thermal Recovery Plant(STRP). The TCZWM center is projected to be built by early 2023 and starts the full operations
by the end of year 2023 to eliminate plant waste about 140,000 tons/yr and to generate about 45,000 tons/yr of high-value
product.
