Figure S.1

This figure describes the major steps for producing steel using the non-integrated steelmaking process. Raw materials such as scrap steel, fluxes, and direct reduced iron are processed in an electric arc furnace to produce molten steel. The steel thus obtained is treated in "ladles" and the molten steel is cast into the desired shape. Electric arc furnace and ladle metallurgy processes result in air emissions and solid wastes, while casting process produces air emissions, wastewater and solidwaste.

Figure 1.2

This figure provides a simplified graphic representation of major steps to produce steel using the non-integrated steelmaking process. Steel scrap, fluxes, direct reduced iron and alloying materials are processed in an electric arc furnace. The steel thus obtained is further treated to impart desired properties and then cast, hot rolled or cold rolled to various shapes. Additional treatments such as anodizing, galvanizing etc., are performed depending on the requirements. This is described more detail in Section 2 (Operational Activities).

Figure 2.1

This figure depicts in greater detail the inputs, outputs and pollutant releases (air, water and solid wastes) at each step in the process. This is also elaborated in Sections 2 (Operational Activities) and 3 (Environmental Concerns).

Figure 2.2

This figure depicts in greater detail the inputs, outputs and pollutant releases (air, water and solid wastes) at each step in the process. This is also elaborated in Sections 2 (Operational Activities) and 3 (Environmental Concerns).
