Waste Disposal and Recycling in Steel Industry

2020-9-1  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 replaced with “by-product” due to intensive re-utilization of these wastes.

Slag recycling recovery

Almost all of the slag from the steel industry in those countries is used for the manufacturing of high-quality products for the cement and building materials industries, aggregates for road construction and fertilizers. Only small quantities end up in waste disposal sites or are used for landfilling.
