Preventing Pollution

Minimizing Environmental Damage in Case of Accident or Disaster

Daikin has systems in place that allow it to minimize environmental damage if there should be an accident or calamity at Daikin production sites around the world. Our Disaster Prevention Manual details how to deal with emergencies like chemical and oil leaks, spills, and earthquakes. The manual is the basis for regular emergency drills.

Training held at each plant (fiscal 2019)

  Main training
Sakai Plant Oil fence installation training assuming leakage (held once, about 20 participants)
Shiga Plant Emergency materials storage check patrol and water quality accident and emergency training (held once, about 20 participants)
Yodogawa Plant Training for assumed chemical substance leakage and evacuation for scenario of heavy rain and flood (including confirming site status using drone) (held three times)
Kashima Plant Disaster prevention training including response training for scenario of fire, man-made disaster, and earthquake (held twice)
Oil fence installation training (Sakai Plant)

Monitoring Environmental Standards

Strict Management at Manufacturing Bases Exceeds Legal Requirements

Daikin controls air and water pollution using voluntary standards that are stricter than national environmental standards and local government by-laws. We regularly measure our various environmental impacts and work to either prevent or decrease them.

Monitored environmental data for Daikin Industries, Ltd.'s four manufacturing bases is on the Daikin website.

Measures for Soil and Groundwater Pollution

Dealing with Soil Pollution at the Yodogawa Plant

At the Yodogawa Plant, it was discovered that the site's groundwater contained concentrations of chloroethylene that exceeded environmental standards. This was reported to the Osaka Prefectural authorities, and we continued to pump up groundwater to prevent pollution from spreading beyond the boundaries of the site.

Groundwater Cleanup Continues at the Kashima Plant

In 2000, the concentration of organic chlorine-based compounds in groundwater at the Kashima Plant was found to exceed environmental standards. Ongoing groundwater cleanup managed to reduce pollution concentrations in the groundwater; however, concentrations still exceeded standards in one area. Cleanup will therefore continue to remedy this situation.

Storage and Treatment of PCBs

Implementing Strict Management and Disposal of Equipment Containing PCBs

Daikin abides by national laws in properly managing equipment containing PCBs (polychlorinated biphenyls). We have been disposing of waste with high PCB concentrations based on PCB disposal plans of the Japan Environmental Storage & Safety Corporation (JESCO), and we were one of the first companies to register with JESCO. Waste with low PCB concentrations is being disposed of based on a Daikin disposal plan.
