Effective Utilization of Resources in Manufacturing Operations (Water Resources)
Independent Practitioner's Assurance
Starting in FY2016, we set new mid-term objectives (refer to chart below) for both domestic and overseas manufacturing facilities and started activities to reduce the amount of water used.
For the manufacturing facilities in Japan, through the reuse of water during the processing and the elimination of wasteful day-to-day practices―mainly in the facilities located in the Hokuriku District which are major users of underground water―water used per unit of manufacturing was reduced by 49.6% compared to FY2010, achieving mid-term objectives ahead of schedule.
In particular, Komatsu Castex Ltd. greatly reduced its water consumption compared to the year before through measures such as circulating the cooling water of the transformer for the arc furnace.
Also, at overseas manufacturing facilities, measures such as purifying the water discharge from the manufacturing process for recycling and reducing wastefulness resulted in water used per unit of manufacturing decreasing by 31.9% compared to FY2010, achieving mid-term objectives ahead of schedule.
Going forward, while considering a re-evaluation of mid-term objectives for both domestic and overseas manufacturing facilities, Komatsu will work even harder to promote activities that reduce the amount of water used.

Reduction in the Amount of Water Used by Suppliers
In order to help further the "Water Usage Reduction Activities" of our suppliers, we are moving forward with expanding Komatsu's water resources reduction activities to our main outsourcing suppliers.
In FY2016, we conducted awareness building activities, and from FY2017, we will select model businesses and implement specific activities.
