Reducing Usage of Hazardous Chemical Substances
In-keeping with the provision of Environmentally-friendly products, we continue to implement initiatives aimed at eliminating, reducing or replacing hazardous chemical substances as part of production processes, both at home and overseas.
Reducing Usage of Hazardous Chemical Substances
In fiscal 2003, the Citizen Group implemented measures to reduce the use of chlorinated organic solvents and hydro-chlorofluorocarbons (HCFCs) and completely eliminated their use in 2008.
The filing status of PRTR substances by the Citizen Group as a whole in fiscal 2011 was as set forth below. A total of 10 substances subject to notice were used, and the volume used increased by 13.7% to 105 tons.
