Environment : Environmental Management Activities for reduction of environmental risks

Activities for noise and vibration prevention

To prevent noise and vibration, group companies of production and recycling are strictly observing the standards of relevant laws and ordinances, and regularly measuring noise and vibration level.

Activities for air pollution prevention

To prevent air pollution, the business offices and factories possessing smoke generating facilities are regularly measuring the amount of smoke such as NOx, SOx, etc. In addition, for the CFC emission control law, we are working on the proper management of business use air conditioners and refrigeration/freezing equipment and the grasp of the amount of CFC leakage, as well as stipulating internal regulations.

Activities for soil pollution prevention

At Kawasaki head office, in constructing the Technology Research Building (tentative name) to be completed in June, 2019, we implemented a soil survey based on the Soil Contamination Countermeasures Act and the ordinance concerning the conservation of living environment such as Kawasaki City pollution prevention.

As a result of collecting and analyzing the soil of 136 blocks with area of 10m x 10m as one block, we found noncompliance in 50 blocks and the Class 1 Designated Hazardous Substances exceeding the groundwater environment standard at 14 spots as for the groundwater.
We reported the result of the soil investigation of Class 1, Class 2 and Class 3 Designated Hazardous Substances and the groundwater investigation to Kawasaki City.

As for one block where Class 1 Designated Hazardous Substances exceeds the wastewater standards, the purification by the bio-process method was carried out and we are monitoring the change-with-time of concentration in the observation well.

Activities for water pollution prevention

In order to conserve the water quality for surrounding water area, we carry out the proper management by strictly observing the waste water standards such as related laws and ordinances and regularly measuring pH, COD, SS (Note 1).

The Aomori Business Office installed a groundwater purification facility and conducts purification and progress measurement every year as organic solvent exceeding statutory standards was detected from groundwater in the soil and groundwater examination conducted in 1999 (then Aomori Fujitsu General Ltd.).
In FY2017, in order to prevent freezing during winter season, we added a heater with a freeze prevention sensor to the piping inside the purification facility and made the bypass of the pipe so that the remaining water will not accumulate in the piping when stopping the pumping.

Activities for chemical substance pollution prevention

To prevent pollution by chemical substance, the procedure to prevent the diffusion at the time of leakage is checked periodically.

Also, the equipment using polychlorinated biphenyl which was used in the factory premises in the past and the parts containing polychlorinated biphenyl used for the collected products are stored properly in the special storage warehouse of the head office until destruction treatment is carried out.
