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.

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 have appropriately stored and managed PCB waste according to the Waste Management and Public Cleansing Act and the Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes. We check the storage and management status on a periodic basis and report the results to the government body every year.

During fiscal 2018, we disposed of two low-pressure capacitators containing PCBs through the Japan Environmental Storage & Safety Corporation (JESCO). The remaining fluorescent lighting ballasts containing PCBs will be stored and managed in accordance with instructions from the government and associated organizations.

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.
