Chemical Substances Control
The SII Group believes that the safe and appropriate chemical substances control is corporate responsibility and important activity for risk management. In terms of chemical substances used in our manufacturing processes at sites in Japan, we control the use and emission of PRTR* substances, 23 substances voluntarily specified by SII, and 100 VOC (volatile organic compounds) substances.
*PRTR (Pollutant Release and Transfer Register): This system is designed to assess, gather, and disclose data on the volume of chemical materials handled, amounts released into the environment, and volumes transferred in waste materials to points outside the site locations. Companies collect data on the relevant substances and report them to the appropriate government agency once a year.
FY 2019 Overview
The FY 2019 total emission of chemical substances subject to control in manufacturing process was 24.3 tons, which was approximately 2 tons less than the total for FY 2018. The amount of PRTR substances handled was 73.4 tons, which was 7.2 tons more than the amount for FY 2018. The breakdown of the amount handled and emitted is shown below.

Measures against Ozone Depleting Substances
SII has completed the total elimination of specified chlorofluorocarbons (CFCs), which are ozone depleting substances, used in our manufacturing processes, however we still use CFCs as refrigerant for chillers and air-conditioners. Our sites in Japan are in accordance with the CFC emissions law and have been striving to prevent leaks during use in addition to disposal through conducting simple checks and periodic inspections since FY 2015.
