Carbon dioxide (CO 2) is considered the most common and abundant GHG in the atmosphere that is generated as a result of various natural and industrial processes (Figs. 1, 2).Power plants and manufacturing plants are the major sources with steel industry accounting for 3–4% of the global GHG emissions (Yu and Wang 2011).The …

In particular, the annual amounts of iron slag and steel slag globally generated were estimated to be 390 Mt and 290 Mt, respectively, in 2022. Steel and iron-making slag contain 30–60 wt% of calcium oxide (CaO) and 3–15 wt% of magnesium oxide (MgO), suggesting high CO 2 storage capacities [19] .

Slag is created by the separation of the molten steel from impurities inherent in iron ore and scrap metal. Slag impurities degrade steel. For example, slag will pull phosphorous from iron and, if not removed, the phosphorus reverts back into the steel, lowering its quality. It also causes substantial wear and tear on the vessels involved.

Steel slag is a by-product of the steel industry. Understanding of the chemical, mineralogical, and morphological properties of steel slag are necessary for its use in sustainable practices.

The global steel slag market size was valued at USD 25.66 billion in 2022 and is projected to grow from USD 26.83 billion in 2023 to USD 38.28 billion by 2030, exhibiting a CAGR of 5.2% during the forecast period.
