Basic ideas

Basic ideas for water resource

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 manufacturing plants are located. We are promoting efficient use of water companywide as water recycling and manufacturing process improvements.

Objectives

We are committed to reducing water consumption by clearly identifying the amount of water required for production and reducing excess water use. In 2022, we worked on the target of reducing usage at Tokai Carbon’s operation sites by at least 1% from the FY2018 level, and achieved the target with a 4% reduction. In 2023, we will expand the target scope to our major Group companies to reduce water usage with the goal of being below the 2021 level (9 million m3/year).

Targets and progress are discussed in the Sustainability Committee, chaired by the president, and reported to the Board of Directors on a quarterly basis.

Initiatives

Water risk assessment

We identify areas of water stress by referring to the WRI Aqueduct. In 2022, we conducted a survey of all 51 sites(*1) in Japan and overseas, including our head office, branch offices, and group companies.
Of these, five sites were identified as having high water stress (*2). Apart from one sales site, we conducted a detailed survey of past floods, droughts and water consumption for each site to confirm that they are at low risk.

• *1 As of September 2022
• *2 Sites that were classified as "High" for overall water risk among the risk items in the chemical industry of WRI Aqueduct.

Initiatives to reduce water consumption

Tokai Carbon’s operation sites take various measures to achieve the goal of reducing water consumption.

Performance

Environmental data

In calculating performance, water consumption is computed as the amount taken in.
