The local authority in Suzhou established industrial enterprise transformation and upgrade guiding fund to foster high-quality industrial development, elevate smart manufacturing upgrade as well as amplify the support for corporate transformation and innovative development. OTIZ carefully reviewed the application materials, consulted with governmental agencies and completed the application after assessing actual plant operations.

1. In 2021, OTIZ devoted NT$1.3 million to transport the residual gas from the cryogenic nitrogen generator from North Plant to South Plant. South Plant was able to operate with one less nitrogen generator, which reduced energy consumption by 820 MW, carbon emission by 577 tCO₂e and energy costs by NT$2.41 million per year.
2. OTIZ spent NT$4.12 million to replace the dated 400kW rotary screw air compressors with the 250 kW models. Under the premise of maintaining consistent production, the plant reduced the compressor pressure from 14K to 12.5K. The pressure reduction lowered energy consumption by 520 MW, carbon emission by 365 tCO₂e and energy costs by NT$15.4 million per year.

In sum, OTIZ put in a total of approximately NT$5.42 million into energy conservation projects in 2021, which reduced energy consumption by 1,340 MW, carbon emission by 942 tCO₂e and energy costs by NT$3.95 million per year.

OTIZ beat the competitions to represent Wuzhong District in the municipal and provincial level competitions. The plant ultimately stood out among the competitors with its smart machine shop, winning the title of Advanced Transformation and Upgrade Enterprise of Manufacturing Industry during the assessment conducted by Suzhou Engineering Technology Research Center. Accompanying the title is a NT$27.6 million reward. In 2022, the plant continues to devote approximately NT$170 million to smart transformation endeavors to continue serving as the role model of smart manufacturing plant.
