Developed by Midrex Technologies, Inc., a wholly owned subsidiary of Kobe Steel, the MIDREX® Process utilizes natural gas to make direct reduced iron. As the world’s leading direct reduction process, it is used in around 70 plants worldwide, particularly in the Middle East.
Kobe Steel’s original seawall technology helps to reduce overtopping and minimize damage from high waves, such as from typhoons. The gentle flare helps to break waves and dampen their force. The flared seawalls eliminate the need for the high seawalls eliminate the need for the high seawalls and wave dissipating concrete blocks that are commonly used, better preserving scenery and sandy beaches. Due to the technology’s ability to protect coastal regions, demand is expected to grow nationwide.
Grid-Type Sabo Dams for Erosion Control
