In the inner bays and coastal districts in Japan, many sea areas have vertical seawalls installed after land reclamation and suffer from eutrophication due to the inflow of domestic wastewater from rivers, requiring environmental restoration. In these areas, problems such as red tide and blue tide, as well as decline in marine resources, have emerged. The applicability of steelmaking slag was examined to improve the bottom sediments in several sea areas. The experimental results presented in this paper showed that massive steelmaking slag controlled the occurrence of sulfide, and that the materials were available as a submerged embankment material, which can be used for a base of algae and benthonic organisms. It is also found that the granules of the steelmaking slag can be an effective base and can supply nutrients for attached algae. (Copyright JFE Technical Report)
