produced via the integrated, direct reduced iron or electric arc furnace route, requires the transport, storage, handling, heating and transformation of raw materials. all these processes have the potential to generate emissions to air *, primarily in the form of dust (or particulate matter (pm), sulphur
dioxide (so2), and nitrous oxides (nox). other emissions generated in small quantities include dioxins and heavy metals, typically attached to dust particles. today, all steel plants are subject to environmental regulation, which set requirements to restrict emissions to air. this regulatory framework...
