For the Environment Reducing Waste and Preventing Pollution

Through pursuing the 3Rs (reduce, reuse and recycle) aimed at the reduction and recycling of industrial waste from our operations, Kaneka has been able to achieve zero emissions (see note 1) for eleven consecutive years. We are also working toward all group companies in Japan being able to achieve zero emissions.
We also meet all standards for environmental pollution levels in applicable laws and regulations, and in agreements concluded with various municipalities.

Note 1: Kaneka defines "zero emissions" to mean that the final landfill volume is less than 0.5% of total waste generated.


Cutting Waste Sent to Landfill

K J 

We effectively achieved zero emissions in fiscal 2016, with a final landfill volume for Kaneka (see note 2) of 3.0 tons, equivalent to a final landfill rate of 0.005%.
The final landfill rate of 45 Group companies in Japan (see note 2) in fiscal 2016 failed to achieve zero emissions, with a rate of 1.8%.
We will work on controlling the emission intensity of industrial wastes and reducing the final landfill rate.

Note 2: The landfill volume, landfill rate, industrial waste volume, and recycling amount of Kaneka and Group companies in Japan indicate totals for the company as a whole, including its facilities and companies other than the plant department.

Proper Disposal of Industrial Waste

K J 

We conduct regular site visits of our waste processing contractors, and carry out inspections based on a checklist to confirm that waste is being processed in the proper manner.

3R Initiatives

K J 

Because reducing waste leads to improving global sustainability by means of resource savings, cost reduction, as well as carbon dioxide emissions reduction, Kaneka is pursuing waste reduction on a company-wide basis.
We at Kaneka and group companies in Japan are pursuing activities at each of our production facilities, mainly through the "3R" approach to achieve waste reduction and recycling of materials. In addition, we have been pursuing improvements, utilizing the Material Flow Cost Accounting (MFCA) approach, which involves all employees in manufacturing, research and other sections.

Preventing Air and Water Pollution

K J 

Kaneka is in compliance with the standards specified in the Air Pollution Control Act and the Water Pollution Control Act as well as the criteria included in agreements made with local governments. Regarding the atmosphere, soot and dust emissions levels for Kaneka in fiscal 2016 were slightly lower than the previous fiscal year, while SOx and NOx emissions were increased. All substances excluding nitrogen increased in water.

Note3: From fiscal 2015, our water consumption amount and wastewater volume include those generated from non-manufacturing facilities other than the plant department.

Check & Act

The increase in final landfill volume of Group companies in Japan in fiscal 2016 was because substances that had been treated as valuables were landfilled and also because there was an increase in the number of companies subject to data collection. We will improve the landfill volume reduction.
We will continue to work to further reduce our impacts on the water and the air, and to respond rapidly in the event of any abnormalities.
