The Health Risk of SLAG – an Industrial Waste Product ...

SLAG is an industrial waste product – there is no standards about the quality of it. What is in it depends on what was the raw material used for the production of iron – e.g. scrape metal, iron ore,.. Orcem claims that absolutely none of the Orcem’s material or products are toxic. But Material

Utilization of waste from steel and iron industry as ...

05-07-2019  Slag has been acquired as waste from steel and iron industries and used as secondary raw material, because it does not contain any energy. Figure 9 shows the LCA of mortar model in GaBi Software. The scope of study is the comparison of selected ternary blended mortar to control mortar to get the most suitable option according to their environmental impact.

Waste Disposal and Recycling in Steel Industry

01-09-2020  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.
