Reducing Environmental Impacts at
The Guangzhou factory of Hitachi Elevator (China) Co., Ltd., which is the Hitachi Group’s largest overseas elevator manufacturing site, acquired ISO 14001* certification in 2000, and has been working hard to reduce environmental impacts from various aspects ever since.
For example, it has constructed additional wastewater reuse systems so that the water used in all manufacturing processes can be reused. Compared to the pre-construction level, the factory was able to save around 30,000 tons of mains water per year. Measures such as replacement with high-efficiency light fixtures and transition to inverter control and dispersed installation of air compressors also reduced CO2 emissions.
Individual employees are constantly aware of the environment and proactively pursue activities such as voluntary collection of used batteries.
