The FTIS estimates that this will save NT $ 5.8 million per year in overhead for materials, water, and wastewater treatment fees, as well as cut CO2 emissions by 768 tons. Because total investment for the whole factory would come to NT $ 12 million, after evaluation it was decided to first change just one-third of the vats (five machines).
產基會估算，這樣一改，每年除了可減少 580 萬元的燃料費、水費及廢水處理費，也降低了 768 噸的 CO2 排放；由於整廠投資需要 1,200 萬元，因此評估後先做三分之一（5 台機器）。
