Pellets are mainly used for blast furnace steelmaking. This dataset includes the primary raw materials, auxiliary materials, energy, atmospheric emissions, and waste from the production process. Gypsum produced from desulfurization is a by-product of this process. The infrastructure such as production equipment manufacturing and plant construction is not included within the boundary of the dataset. The data inventory is formed by aggregating data from multiple sources. The production process for pellets includes raw material mixing, pellet forming, drying, and calcination stages. Chain grate - rotary kiln technology is primarily adopted for the calcination process.
