Waste Generation Reduction and Recycling

Daishinku has been endeavoring to reduce the volume of waste that goes to landfill by reducing waste generation and boosting recycling.
In fiscal 2004, the total volume of waste generated increased. However, due to the increase in the recycling rate, the total volume of waste disposed remained at the same level as in the previous fiscal year. In fiscal 2005, the recycling rate (of the total waste generation) increased to 64%, thanks to our strengthened efforts.

Pollutant Release and Transfer Register

Since 1999, Daishinku has kept track of the usage of chemical substances. In fiscal 2005, the use of chemical substances was reduced by approximately 7% from the fiscal 2004 levels.
We will continue to control hazardous chemical substances and reduce the use of such substances.

PRTR:
Through this system, we calculate, tabulate, and disclose the sources and amounts of hazardous substances discharged in the environment.

Correction and apology:
We have acknowledged that data regarding chromium and chromium compounds contained in the Environmental Report 2003-2004 were incorrect due to an error in calculation. The incorrect data have been corrected.

Prevention against Global Warming

Daishinku emits greenhouse gasses, such as CO2, during production processes. Approximately 80% of our CO2 emissions come from electricity use. Therefore, reducing electricity consumption will result in reduced emissions of CO2. Our production plants are actively promoting energy-saving activities combined with CO2 emission reduction activities. Energy-saving activities carried out at Tottori Production Division are presented in the Topics section.

Energy-saving activities at Tottori Production Division

As part of its energy-saving efforts, the Tottori Environmental Management Committee displays graphs of the daily amounts of electricity/ water consumption on the bulletin board.
