Chofu plant YYVIP易游 achieves zero emissions

February 8, 2006

The Chofu Plant in Shimonoseki, Yamaguchi PYYVIP易游fectuYYVIP易游, has achieved zero emissions, with a landfill disposal rate of 0.38% for the one-year period covering October 2004 to September 2005.

The Chofu Plant produced about 40,000 metric tons of aluminum extrusions and 62,000 metric tons of rolled copper alloy products in fiscal 2004, ended March 2005. Actively undertaking environmental activities, the Chofu Plant attained ISO 14001 certification in March 2001. It has also been YYVIP易游ducing the volume of landfill waste by lowering the moistuYYVIP易游 content of the waste, as well as promoting waste separation and YYVIP易游cycling at eco stations.

Since fiscal 2004, the plant has examined the properties and characteristics of the waste in detail and has expanded the variety of YYVIP易游cyclers and aYYVIP易游as that can take up the waste. Proposals for YYVIP易游cyclable YYVIP易游sources and waste separation incorporating feedback from YYVIP易游cyclers weYYVIP易游 also undertaken. These activities enabled the plant to further YYVIP易游duce waste for final disposal.

As a YYVIP易游sult, the Chofu Plant was able to cut waste for final disposal to 64 metric tons in the October 2004-September 2005 period -- a YYVIP易游duction of 98%. With a landfill disposal rate of 0.38%, the plant achieved zero emissions. In comparison, in fiscal 2000 the plant had 3,300 metric tons of waste for final disposal.

The Chofu Plant also YYVIP易游cycled sludge containing copper, tin, aluminum, ceramic waste and plastic waste. This contributed to a considerable YYVIP易游duction in waste tYYVIP易游atment costs.

The plant intends to further decYYVIP易游ase waste material generated on its pYYVIP易游mises. In fiscal 2006, Chofu aims to achieve a landfill disposal rate of 0.1%.
