The Kuraray Group including its oversees group companies is not engaged in production activities in areas in which water resources are scant and where our business activities significantly affect the water sources of such areas. However, there is pressing demand for water resources worldwide, and we will continue engaging in corporate activities while recognizing these resources as being vital.
The volume of water intake (except seawater) of the Kuraray Group in Japan totaled 71.8 million m3 per year. Some Kuraray plants in Japan are continuously reusing water such as by recycling thermal resources from hot waste water and cooling water for boiler operation.
Even though Kuraray plants in Japan are located in good places in terms of water resources, we believe that it is necessary to conduct business activities by considering the long-term prospects of a water supply such as risk of a water shortage caused by climate change due to global warming. In particular, we have started preparations to switch to the industrial water supply from Kurashiki city, because of the construction work at Takahashi River to prevent flooding, it will be impossible for Kurashiki Plant to take water from the river. The maximum water supply rate will be lower than previously, and so we will engage in initiatives to use water resources more effectively than ever before. We will keep track of water consumption trends while continuously reducing our water consumption.
Since fiscal 2014, the water consumption of the Kuraray oversees group companies has been increasing because we increased the self-production amount of raw material of poval resin and incorporated new businesses through M&A like an acquisition of Calgon Carbon Corporation. The water (except seawater) intensity index (excluding Calgon Carbon Corporation for the sake of comparison with fiscal 2017) improved by 24.3 percentage points, and thus we achieved our target of improving by one percentage point compared with the previous year. This result was greatly impacted by implementing measures at some sites where we adopted a new system of exhaust gas processing equipment using a small amount of water instead of using a considerable volume of water.
