Releases of chemicals used in factories are closely controlled in accordance with the law

Chemicals are carefully monitored and managed to minimize releases

Every effort is made to manage chemicals appropriately using Safety Data Sheets (SDS). Chemicals subject to PRTR Law (Japanese Law concerning Pollutant Release and Transfer Register) are monitored and reported on in accordance with relevant legislation.

Active steps are being taken to minimize releases of chemicals into the environment, including enhancing the capacity of wastewater treatment systems and installing deodorizing equipment.
