Utilization of Steelmaking Slag in Sea Areas
Ryo Inoue
Abstract
In recent years, many studies have been conducted on the use of steelmaking slag to improve marine environments. By burying steelmaking slag alone or in a mixture of steelmaking slag and soil (or sand) containing organic materials in marine environments, the growth of marine plants can be promoted and rocky-shore denudation can be repaired. Furthermore, it is known that the occurrence of blue tide can be prevented. These effects are understood to be the result of a steady supply of iron, which is a major component of steelmaking slag. This chapter outlines the generation and conventional applications of ironmaking and steelmaking slags, which are by-products of the steel industry. Author then highlight previous studies on the environmental protection of sea areas using steelmaking slag and discuss novel applications of steelmaking slag.
