Construction of Cyanide Wastewater Recycling System |
 |
| At the Kagoshima Hayato Plant, wastewater containing cyanide is generated in the plating process. After removing hazardous cyanide and precious metals from this wastewater using ion exchange resin, about 904m³ of wastewater was recycled by the water purification system at our facilities. |

Introduction of a Nickel Recovery Facility |
|
At the Shanghai KYOCERA Electronics Co., Ltd., the water used in production processes such as the plating process is treated in the wastewater treatment facility.
We have introduced a nickel recovery facility and recovered about 1 ton of nickel annually as valuables. |

Introduction of Wastewater Recycling System |
|
| At the ELCO Europe GmbH, water containing hazardous substances generated from processes was treated in the wastewater treatemt facility and previously recycled in part. By renewing and improving the facility, we were able to improve the recycling rate, thus reducing the environmental burden on waterways by recycling 27,900m³ of wastewater annually. |

Ozone Layer Protection |
|
| In addition to the materials regulated by the Montreal Protocol, Kyocera eliminated other chlorine solvents. As a result, CFCs and other FreonsR, carbon tetrachloride, 1,1,1-trichloroethane and halons were completely eliminated in 1992. The new specified control substances of methyl bromide and bromochloromethane were also completely eliminated. For chlorine solvents other than specified control substances such as trichloroethylene, tetrachloroethylene and dichloromethane were also voluntarily eliminated by 2000. |
