Basic Philosophy on Water Resources

The Mitsui Chemicals Group works to manage efficient water usage and water preservation.

Basic Philosophy on water resources

  1. We recognize that water is a finite and precious resource, and regard water preservation as a key priority on a global scale.
  2. We make every effort to use water efficiently as we recognize quality water resources are crucial to our operations.
  3. We appropriately manage water on a case-by-case basis for each country and region in which we operate, in recognition of the fact that water resources distribution varies both geographically and temporally.

Preserving Water Resources

Reducing Emissions of Water Contaminants

We are committed to reducing emissions of water contaminants such as chemical oxygen demand (COD), nitrogen and phosphorus, to preserve water quality.
Emissions at all of our domestic production sites are significantly lower than levels required by law or other legislation. The Mitsui Chemicals Group is committed to preserving water quality on an ongoing basis.
