Japan: JFE Steel and Innoqua, a startup linked to the University of Tokyo, are working on using slag as an artificial bed for coral reef restoration. JFE Steel has recently installed a 1m fish tank in the lobby of its Tokyo-based headquarters as part of a feasibility test for the biodiversity initiative, according to the Nikkei newspaper. The companies are testing Marine Block, a product made from slag that is processed using a proprietary technique to allow coral to attach to it easily. The initiative will examine which species of corals are most likely to attach to the Marine Block, the ideal growing conditions and then move on to larger-scale coral breeding.

The Japanese steel industry produces over 35Mt/yr of slag. The majority of it is used in infrastructure projects. JFE Steel hopes to use about 10% of the slag it produces in 2030 in port and marine applications.
