Slag is an industrial waste generated during the steelmaking process. Electric arc furnace slag (EAFS) and ladle furnace slag (LFS) are both produced at different stages of steelmaking process, respectively, in electric arc furnaces and refining ladle furnaces. As part of this research, an extensive suite of engineering and environmental …

We found similarities among solid wastes from a common generation source as well as notable differences among the different generation sources: slags and sludges from waste acid treatment and wastewater treatment units had a water content of 27.43–52.71% and 51.14–68.27%, respectively, which were significantly higher than …
On the other hand, the steel slag waste produced is 10–15% per ton of steel production [43], [46]. In this manner, the annual volume of steel slag waste might reach over 300 billion tons. Therefore, recycling and utilizing steel slag waste is essential to lessen its detrimental effects on individuals and the environment.
Slags from the ferrous and nonferrous metallurgical industries have been used to treat toxic contaminants in water and wastewater. Using slag as a recycling or renewable resource rather than a waste product has environmental and economic benefits. Recycled smelter slags can be used in both in situ and ex situ treatment. However, their …
The waste heat of slags amounting to ∼220 TWh/year at temperatures in the range of 1200–1600 °C, presents an opportunity to lower the energy intensity of metal production.
Waste production by industrial sectors can harmfully impact the environment, and its amount has been increasing globally (Aljerf, 2018b). Environmental Protection Agency in the United States ... Utilizing waste materials (e.g., steel slags, ferronickel slags, copper slags, and copper tailings) from industry for construction …
The advent of industrialization has produced an enormous amount of industrial waste slag, which drastically pollutes environmental resources. This study examines the production, stability, and …
