Action for Prevention of Global Warming

At NDK, we have created a midterm plan including concrete reduction target to reduce CO₂ emission which is the one of the cause of global warming, and promoting it. We are also promoting energy saving activities through such as reduction of energy maintenance loss (complete elimination of waste), reduction of specific energy consumption loss, technology improvement for equipment.

CO₂ emission and intensity

　

　

　

CO₂emissions have been significantly reduced, primarily through the transition to green electricity. Emissions intensity (CO₂ emissions per unit of sales) has also decreased year by year.

Waste Reduction

A wide variety of waste is generated through business activities. To reduce waste which is to be disposed finally, NDK sorts and recycles waste from a perspective of efficient utilization of limited resources and reduction of environmental burden.

Waste emission and recycle rate

　

　

To promote the effective use of resources and reduce environmental impact, we are advancing waste separation and recycling initiatives.
In FY2009, we achieved zero emissions, and since FY2010, we have continuously maintained a 100% recycling rate.

Management of Chemical Substances

At NDK, based on PRTR law(*), we work on the reduction of hazardous substances (class 1 designated chemical substance) emission (to air, water and soil) in addition to monitoring for handling amount, emission and moving amount of objective chemicals, and report to government. (*) Law concerning Pollutant Release and Transfer Register.

Use amount/ moving amount of hydrogen fluoride and its use intensity

　　　

　

　

In accordance with the PRTR Law, we monitor the handling and emissions of designated chemical substances and are working to reduce emissions.Currently, the only designated substance is hydrofluoric acid and its water-soluble salts, and we are controlling environmental releases through process improvements and wastewater treatment.

Prevention of Air and Water Pollution

Regarding water pollution prevention, we have set waste/effluent treatment facilities in order to comply with the emission standard of laws and legislations. Aiming at the establishment of recycling society system, positive activities are promoted. Also at NDK there is no facility applicable for air pollution control law.
