As part of its environmental management policies, the Kobe Steel Group is committed to "environmentally friendly manufacturing." We pursue this commitment on a variety of fronts, including improvements to sustainable manufacturing processes, updates to equipment, introduction of efficient state-of-the-art equipment, and introduction of pollution control equipment, working to reduce environmental impact from soot and other sources.
In the future, we will continue to further limit emissions.
In addition to measures that are meant to reduce energy consumption and limit production of SOx (sulfur oxide) during manufacturing processes, such as reductions to fuel consumption, use of low-sulfur fuels, and switching to city gas, we have also implemented exhaust-related measures such as desulfurization.
Likewise, in order to reduce NOx (nitrogen oxide) emissions, we have implemented efforts such as the use of low NOx combustion technology and energy-saving measures.

At Kakogawa Works, voluntary targets for dustfall in three neighboring locations have been set at 3 tons/km2/month or less, with a variety of measures set in place to maintain this goal.
All targets were met in fiscal 2016.

The Kobe Steel Group strives to conserve water through measures such as improvements to manufacturing processes and wastewater recycling. Additionally, by purifying drainage from manufacturing processes using specialized treatment systems, we strive to reduce impact on public waters.
Drainage from the steelworks undergoes coagulative precipitation, sand filtration and other purification processes, and is reused on-site. As a result, approximately 97 percent of the water is recycled at the Kakogawa Works.
