Read MoreThere is no current global growth in blast furnace slag production, due to the rise of Electric Arc Furnace (EAF) steel production. Only around 75% of globally-produced blast furnace slag (BFS) is granulated, creating around 250Mt of GBFS, albeit with 150Mt in China, 30Mt in Japan and 70Mt in the rest of the world. Since around 2000, the most important Chinese steel producers have been investing in granulation and grinding plants for blast furnace slag. It is currently estimated that 95 % of the blast furnace slag is granulated and used entirely in the cement and concrete industry. Almost 70 % of the steelworks slag goes to dumps and landfills 5 (Fig. 13).
