For the Environment Reducing Chemical Substance Discharge

We at Kaneka are working in an ongoing manner to reduce the discharge of volatile organic compounds (VOCs), as well as to voluntarily reduce emissions of six hazardous atmospheric pollutants subject to the Pollutant Release and Transfer Register (PRTR).

Voluntary Plan to Cut VOC Discharge

K J 

We are committed to reducing the discharge of VOCs (see note 1), which are known to cause photochemical smog. In fiscal 2015, total discharge was 1,702 tons, 2.0% increase compared to the previous year. We will continue our efforts to reduce VOC discharge through prevention of leakages from equipment, and by changing production conditions.

Note 1: Volatile Organic Compounds (VOCs) are organic chemical substances that cause suspended particulate matter and photochemical oxidants.

Hazardous Atmospheric Pollutants

K J 

Total emissions in fiscal 2015 of six hazardous atmospheric pollutants (shown in the following graphs) were 23.9 tons, which represented a slight year-on-year decrease of 1.2%. We will continue to implement emissions reduction measures to reduce our environmental impacts.

PRTR Discharge

K J 

We are working to reduce the discharge of substances subject to the PRTR. Total emissions of these substances in fiscal 2015 were 77.0 tons, a decrease of 0.2 tons from the previous year.

Check & Act

In Fiscal 2015, due to the reductions in emissions of N, N- dimethyl formamide and styrene, Kanaka's total discharge subject to the PRTR system decreased by 0.2 tons from the previous year, for a total of 77.0 tons. Discharge by group companies in Japan increased by 5.6 tons and totaled 71.3 tons due to increased emissions of N, N- dimethyl formamide and toluene from expanded production. We will continue our efforts to reduce the discharge of chemical substances while controlling large discharge.
