Water Resource Conservation

At the Fukuyama Plant, wastewater emanating from the dye production process is treated onsite, then released into the Seto Inland Sea. The plant has been producing inkjet printer dyes since the year 2000, and has consequently invested effort into improving wastewater treatment methods, looking into individual processes tailored to production type and examining numerous ways of altering production processes to lower environmental burdens.
The fruits of such activities can be seen in the form of phased reductions in contracted industrial water amounts, which fell from 24,000m³ to 23,000m³ per day in FY2015, and to 22,000 m³ per day in FY2018. Thanks to further polishing of its wastewater treatment methods, the plant is now able to produce more on the same amounts of industrial water. It is also working on reducing the amounts of regular water used both production and equipment cleaning.

As part of its commitment to environmental conservation, Kayaku Safety Systems Mexico (KSM) has embarked upon improving its use of water resources to help resolve issues concerning limited usable water in the surrounding region. KSM mainly uses water for cleaning equipment and containers, and for manufacturing processes.
Improvement activities have involved raising standards for the production process and water treatment, and providing education to make employees more water-resource conscious. KSM’s activities throughout FY2024 resulted in a 44% (6870-liter) reduction in use of water resources.
