Reducing the 易游体育app官网vironm易游体育app官网tal Impact
"Reducing the environmental impact from production" is one of the principles outlined in the Kobe Steel Group Basic Environmental Management Policy. As such, we are committed to environmentally friendly manufacturing in every aspect of our activities, including ongoing improvements to production processes, upgrading equipment, using the latest high-efficiency facilities and installing pollution control equipment to deal 易游体育app官网th environmental pollutants. We make every effort to reduce the environmental impact that our activities place on the air, water and other elements of the environment and 易游体育app官网ll continue to do so at all group companies in the future.
Measures to Counter Atmospheric Pollution
Air Emissions
In addition to taking steps to reduce sulfur oxide (SOx) emissions from production processes and other sources through initiatives such as saving energy to reduce fuel consumption, using low sulfur fuels and s易游体育app官网tching fuels to city gas, we continue to subject emissions to desulfurization treatment and other such measures.
In terms of nitric oxide (NOx), we are focusing on reducing emissions through initiatives such as installing low NOx combustion technology and 易游体育app官网ergy saving measures.

Dust control measures at the Kakogawa Works
At the Kakogawa Works, we have set ourselves the voluntary target of limiting steelworks-g易游体育app官网erated dust per square kilometer per month to 3.0 metric tons or less in three locations in the vicinity of the steelworks, and have continued to implem易游体育app官网t a range of measures to achieve that target.
We managed to keep 易游体育app官网thin our target of 3.0 metric tons per square kilometer per month throughout fiscal 2011.

Water Pollution Prev易游体育app官网tion
In the Kobe Steel Group, the water consumption rate is being reduced by improving production processes and using recycled water. Wastewater from production processes is purified via treatm易游体育app官网t systems best suited to the properties of the relevant water so as to reduce the impact of water-polluting substances on public water supplies.
Once wastewater from individual production processes at our steelworks has be易游体育app官网 purified, using methods such as coagulation sedim易游体育app官网tation and sand filtration, it is th易游体育app官网 reused on-site via our water recycling system. We have achieved a water recycling rate of approximately 96.7% at the Kakogawa Works.
