Waste Disposal and Recycling in Steel Industry

Solid wastes in steel plants are essential by-products generated during various processing steps involved in the production of iron and steel. Solid wastes generated by integrated iron and steel works cause environmental pollution and therefore must be discarded. Until the last decade, the slag, dust and sludge generated by integrated steel plants was called waste", but now this term has been ...

Alternatively, the dressed ore can be used to produce iron-rich sinters i.e. semi-fused and solidified lumps of iron oxide. Previously, the ore-based steelworks in Sweden had their own sinter plants but nowadays pellets are mainly used as a feedstock in the production of ore-based steel. The last Swedish sinter plant was shut down in 1995.
