“…However, due to its high production volume and technological barriers in its valorization process, deposition in landfills is still the principal final destination of LFS. Other applications may be for agricultural and environmental purposes [46,47], soil amendment [48], heavy metal fixation [49,50], and even water depuration [51]. The main technological barriers in the use of LFS as a cement replacement are due to its volumetric instability and low cementing power/hydraulic activity problems.…”

“…LF slag had also been used to fertilize the soil for planting Amaranthus paniculatus L. plants. Using LF slag in moderate amounts helped increase the growth rate of the plants without any changes in the morphophysiological factors [78,123]. Ghizman et al [124] used LF slag to increase soil acidity.…”

Ladle slag is a byproduct formed during the ladle refining stage of steel making. It is a dusty material that has been considered industrial waste. Technical advancements towards a sustainable industry led to the development of different applications for ladle slag. Depending on the processing methods during the steel slag production and the weathering of the slag post‐production, the elemental composition of the steel slag largely varies. Owing to this, its characteristics cannot be generalized and specific applications depending on the sources are developed. It is generally used in construction materials, soil rejuvenation, and CO2 capture. This paper reviews the production process, the mineralogical and morphological properties, stabilization techniques, and the applications of ladle furnace (LF) slag. One of the prime focuses of waste remediation and sustainable industry is to find meaningful ways to turn waste into products. In this respect, a comprehensive review of the properties of LF slag and its current application will help provide a framework for the development of future sustainability goals. With increased slag usage, the ladle refining process of steelmaking can be turned into a more carbon‐neutral process.

“…However, a clear trend that F v /F M elevated with enhancing doses of blue light until it achieved a peak at B 75 , after which the lowest value among all treatments was observed in B 100 . A decrease in F v /F M implies a decrease in the maximum quantum yield of an open photosynthetic system II (PSII), as well as an increase in light dissipation, indicating damage to the reaction center [39]. All the light treatments, except B 100 , had no significant effect on Y(II).…”

Alterations of Amino Acid Concentrations and Photosynthetic Indices in Light Irradiated Arabidopsis thaliana during Phytoextraction

Hyperaccumulation of heavy metals is substantial in some hyperaccumulators; however, few studies have been conducted to reveal the effect of light irradiation on the variations of representative amino acids and photosynthetic indices, which can represent the antioxidant capacity of plants during phytoremediation. The physiochemical responses of Arabidopsis thaliana to Cd stress were compared during six light irradiation treatments. The results of the experiment showed that the stress adaptation of A. thaliana was enhanced in all light irradiation treatments, except for monochromatic blue-light irradiation. The concentrations of glutamic acid and glutamine decreased significantly in pure blue light compared with the other treatments. The decrease in the concentrations of these two amino acids might be induced by an intensive biosynthesis of defensive factors, as manifested in the declined photosynthetic indices. Concentrations of aspartic acid and asparagine involved in the ammonification, absorption, and transportation of nitrogen in vascular plants increased in the red and blue combined irradiation treatments compared with the control, corresponding to the improved photosynthetic capacity of the species. The concentration of proline, which can represent environmental stresses including metal toxicity and excessive light energy, generally increased with an increasing ratio of blue light. This study proposes the key roles of amino acids and photosynthetic indices in light-motivated Cd pollution responses in A. thaliana.
