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 and spills. The manual is the basis for regular emergency drills.

In fiscal 2017 at the Yodogawa Plant, we teamed up with the fire department and police in conducting two chemical disaster response drills that simulated a fire at night and included the use of a drone. We also conducted an evacuation drill that simulated a large earthquake and tsunami. At the Kashima Plant, a total of 110 employees took part in fire drills and in semiannual drills to prevent the spread of pollution from hazardous substances and protect workers from harm. At the Sakai Plant during June Environmental Month, hands-on training was held in how to deal with oil leaks. At the Shiga Plant, drills were held for plant employees and employees of Daikin contractors.

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 Web site.

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. Chloroethylene is a breakdown product of tetrachloroethylene and trichloroethylene and a substance newly added to the list of designated chemical substances in April 2016. 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.

Disposal and Treatment of Equipment Containing PCBs

Plants Items disposed of Storage and disposal plan
FY2017 FY2018 and on
Shiga Plant 1 low-PCB-concentration transformer 126 ballasts
Sakai Plant 72 liters of insulating oil, 1 condenser, cloths for wiping condenser oil 7 ballasts, 200 ml of insulating oil
Yodogawa Plant 448 ballasts 6 transformers, 1 condenser, 5 switches
