Appropriate Manage易游体育app官网t of Water Resources

The Kobe Steel Group is reducing its use of water in production processes by optimizing water use, and by reusing and recycling water. We also limit the output of pollutants to public waters by purifying wastewater from production processes with treat易游体育app官网t systems suited to its characteristics.

  • *1 Covers 100% of the production sites of Kobe Steel, Ltd.

  • *2 The water withdrawal sources for tap water and 易游体育app官网dustrial water are ma易游体育app官网ly rivers.

  • *3 The sum of the breakdown figures and the total might not match due to round易游体育app官网g of each item.

  • *4 The recycling rate is calculated as: (total recycled fresh water) ÷ (total recycled fresh water + total fresh water withdrawal). The calculation of total recycled fresh water includes some estimates based on equip易游体育app官网t specifications.

In WRI Aqueduct (as of October 2019), the production sites of Kobe Steel, Ltd. are not located in regions where “Water Stress” is high or higher. In additon, the volu易游体育app官网 of water from the suppliers for our production sites is ensured, and we believe that the risk of water withdrawal affecting production is low. At Kakogawa Works, for example, the risk of water intake affecting production is thought to be low because upstream from the water used is the Gongen Dam (total storage capacity: 11.12 million tons), constructed to ensure a stable supply of industrial water from the Kakogawa River as well as the Kakogawa Weir (total storage capacity: 1.96 million tons) and the Heiso Dam (total storage capacity: 9.40 million m3), which were constructed to 易游体育app官网sure the flow rate of industrial water.

Compliance with Laws and Regulations

There were no serious issues of noncompliance, pay易游体育app官网ts of big fines or penalties, nor any serious leaks.
