Water is essential for Tokai Carbon’s business activities, and we are also aware that it is a vital resource in the local communities where our company’s plants, etc. are located. Because of that, we are promoting efficient use of water companywide through water recycling and manufacturing process improvements.
At Tokai Carbon, we use WRI Aqueduct to identify water-stressed regions. In 2019, we conducted a survey that targeted all 45 of our domestic and international bases (*1), including our Head Office, branches, and group companies.
Among these targets, one base was determined to have high water stress (*2), but after conducting a detailed survey of the conditions that led to the occurrence of floods and droughts in the past as well as water usage (*3), we have confirmed the risk to be low.
Number of violations of water related laws, regulations, etc. in fiscal 2019: 2

At Tokai Carbon, industrial water is used at many of our bases, but some of our bases rely on service water (tap water) and groundwater for their water sources. Our Ishinomaki Plant uses service water (tap water), and at this plant, we made efforts to engage in recycling and improve manufacturing processes with the goal of reducing service water usage by 60%, and in 2019, we achieved a 60% reduction in service water usage (compared to FY2012).
