Komatsu's Environmental and Social Activities Enhancing Quality of Life


Promoting Recycling  Effective Utilization of Resources in Manufacturing Operations (Water Resources)

In FY2014, Komatsu set a new medium-term target of achieving “a 50% or greater reduction in the amount of water used per unit of manufacturing by FY2015, compared to the FY2005 level”. An effort has been made to save the consumption of underground water at Komatsu facilities located in the Hokuriku District, which are major users of underground water. The Company has achieved reductions in the amount of water used per unit of manufacturing by 67.5% compared to the FY2005 level, through the reuse of water during processing and the elimination of wasteful day-to-day practices.

In particular, Komatsu Cabtec Co., Ltd. eliminated its groundwater consumption—which was used for cooling—by installing a chiller in every facility.

Komatsu will continue efforts to save water resources to achieve its medium-term goals.
