Pollution Control

Air Pollution Prevention

The Taisho Pharmaceutical Group not only complies with laws and regulations but also sets its own management standards as required to reduce environmental load.

Water Contamination Prevention

Wastewater from production facilities and research centers is treated appropriately and discharged in compliance with laws and regulations or standards based on agreements with local governments. We set voluntary standards for items at risk of exceeding wastewater standards and constantly monitor the quality of wastewater.

Cases of Exceeding Wastewater Standards Over the Past Five Years
Period Site Event Response
August 2017 Omiya Factory Exceeded standards for suspended solids (sewer) Sludge deposited in the final effluent tank is extracted once a year and treated as industrial waste (Latest : October 20, 2019)
August 2020 Okayama Factory Exceeded standards for Hydrogen ion concentration (pH) (sewer) ・Discharge of wastewater exceeding the standard value into the sewer system.Reported to the authorities and confirmed that sewer water quality was not affected.
・The cause is poor neutralization due to sludge in the drainage tank adhering to the pH meter.Sludge accumulated in the tank is removed every year.(Most recent: March 6, 2021)
・Always monitor discharge into the sewer system.

Implementation of Soil and Groundwater Pollution Measures

We have undertaken continuous cleaning since fiscal 2001 to deal with the soil and groundwater contamination discovered during the factory site soil investigation conducted from November 1999 to May 2000 at the Omiya Factory.

Appropriate Management of PCB Waste

We properly manage storage of polychlorinated biphenyl (PCB) waste materials in compliance with the Waste Management and Public Cleansing Act and Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes. We periodically confirm the status of storage management and report to government authorities every year.

Management of Chemical Substances

We strive to appropriately manage chemical substances that are harmful to the environment, including chemical substances designated under the Law concerning Pollutant Release and Transfer Register (PRTR), and reduce emissions in line with pertinent rules and Taisho Pharmaceutical’s unique management procedures.
