For Global and Local Futures

We contribute to solving environmental problems with a long-term perspective by reducing environmental loads at our global network of manufacturing sites and pursuing energy-saving performance in our products.

Reducing Environmental Loads at
Manufacturing Sites

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 on various aspects of environmental load reduction 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 before the construction, 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 emission.
Individual employees are constantly aware of the environment and proactively pursue activities such as voluntary collection of used batteries.
* ISO 14001: The international standard for Environmental Management Systems set by the International Organization for Standardization.

Reducing Environmental Loads at Manufacturing Sites

Acquisition of the Highest-Class A Grade

The UAG-SN1 machine-room-less elevator uses LEDs for all ceiling illumination, to improve energy-saving performance and extend the lifespan of lighting.
We have adopted systems which reuse the regenerated power generated by motors in some operating conditions, such as when ascending with few passengers and descending with many.
We also conducted energy-saving performance assessment on the basis of ISO 25745, a global standard, and acquired its highest class of A.
We will adopt the same procedures for the new models we develop in future.
