Sustainability Initiatives

Our manufacturing plants are located in Shibukawa City in Gunma Prefecture and Kurashiki City in Okayama Prefecture, and we have been confirmed as having low water risk by the World Resources Institute’s (WRI) Aqueduct Water Risk Atlas and do not operate in water-stressed areas.
We are working to reduce our environmental impact through thorough wastewater management, as well as promoting the use of recycled cooling water to reduce water intake.
There have been no violations of permits, standards, or regulations regarding water quality or quantity for over 10 years.

Shibukawa Plant

With the exception of a few byproducts, the products manufactured at the Shibukawa Plant do not contain any water, and the water withdrawn is mainly used for cooling and heating the manufacturing process, and almost all of it is discharged into the river under strict water quality control by reducing the amount of water withdrawn through recycling.

Mizushima Plant

The Mizushima Plant, like the Shibukawa Plant, uses most of its industrial water for cooling its facilities. Cooling water is circulated using cooling towers to reduce the amount of water taken.
The Mizushima Plant is a member of the Okayama Prefecture Industrial Water Council, which promotes the sound development of the industrial water supply business in Okayama Prefecture.
