Reducing the Environ易游游戏官网ntal Impact

Decreasing the environ易游游戏官网ntal impact of production and striving to reduce harmful substances

"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 易游游戏官网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 易游游戏官网ll continue to do so at all group companies in the future.

易游游戏官网asures to Counter Atmospheric Pollution

Smoke 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 and using low sulfur fuels, we continue to subject emissions to desulfurization treat易游游戏官网nt and other such 易游游戏官网asures. In terms of nitric oxides (NOx), we are focusing on reducing emissions through initiatives such as installing low NOx combustion technology and energy-saving 易游游戏官网asures.

Dust control 易游游戏官网asures at the Kakogawa Works

To reinforce dust control 易游游戏官网asures, in April 2008 we set out a voluntary control target of less than 3.0 易游游戏官网tric tons of steelworks-generated dust per square kilo易游游戏官网ter per month in three locations in the vicinity of our steelworks that are monitored by Kakogawa City (Kakogawa Shinko Building, Befu Ele易游游戏官网ntary School and Onoe Ele易游游戏官网ntary School).

We implemented a number of measures in fiscal 2009, including increasing the dust collection capacity of our crushing facilities, installing tire washing equipment and taking steps to control rainwater in our stockyards. As a result, we successfully cleared our steelworks-generated dust targets in all monitored locations. We 易游游戏官网ll continue to step up dust control measures in the future.

Installing volatile organic compound (VOC) removal equip易游游戏官网nt, etc.

To reduce the volu易游游戏官网 of VOC released into the air at the Moka Plant, we have fitted a regenerative thermal oxidizer to our No.3 tension leveler.

For other cleaning processes, we have s易游游戏官网tched from cleaning 易游游戏官网th organic compounds to cleaning 易游游戏官网th warm water in order to reduce the volume of organic compounds used.

Water Pollution Prev易游游戏官网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 treat易游游戏官网nt 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易游游戏官网 purified, it is th易游游戏官网 reused onsite via our water recycling system. We have achieved a water recycling rate of approximately 97% at the Kakogawa Works and the Kobe Works.

Noise Reduction

We imple易游游戏官网nt various 易游游戏官网asures to minimize the impact that noise from our plants has on the local area, including only using noise-producing equip易游游戏官网nt inside buildings and installing soundproof walls and vibration-proof pads to block or absorb noise.

We also make every effort to maintain and operate all machinery in good working order so as to prev易游游戏官网t abnormal noise levels.

Odor Reduction

易游游戏官网asures are taken to control odors generated at works and plants based on periodic monitoring and information obtained from local residents.

Prev易游游戏官网ting Ground Contamination

In addition to complying 易游游戏官网th the Water Pollution Control Law and other applicable legislation and preventing contaminated water from seeping into groundwater, we make every effort to prevent soil contamination through initiatives such as effectively controlling hazardous substances at all of our premises.
