“…Industrial wastes such as blast furnace slag, steel slag, fly ash, and bottom ash are known to be potential silica fertilizers [ 100 , 101 ]. Particularly, steel slag is a by-product material formed during the process of manufacturing steel from iron, whose volume accounts for 15–20% of the total steel produced [ 102 ]. The basic properties of slag vary according to the manufacturing, cooling, and valorization processes [ 103 ].…”

Silicon (Si), despite being abundant in nature, is still not considered a necessary element for plants. Si supplementation in plants has been extensively studied over the last two decades, and the role of Si in alleviating biotic and abiotic stress has been well documented. Owing to the noncorrosive nature and sustainability of elemental Si, Si fertilization in agricultural practices has gained more attention. In this review, we provide an overview of different smart fertilizer types, application of Si fertilizers in agriculture, availability of Si fertilizers, and experiments conducted in greenhouses, growth chambers, and open fields. We also discuss the prospects of promoting Si as a smart fertilizer among farmers and the research community for sustainable agriculture and yield improvement. Literature review and empirical studies have suggested that the application of Si-based fertilizers is expected to increase in the future. With the potential of nanotechnology, new nanoSi (NSi) fertilizer applications may further increase the use and efficiency of Si fertilizers. However, the general awareness and scientific investigation of NSi need to be thoughtfully considered. Thus, we believe this review can provide insight for further research into Si fertilizers as well as promote Si as a smart fertilizer for sustainability and crop improvement.

“…Throughout this period, a large amount of CO, iron and other semi-metallic elements are generated and enter the wet dust removal system in the form of flue gas. Under the treatment of the wet cleaning system, these dusts are dispersed in water to form the suspended sewage [7,8] After solid-liquid separation, the sewage forms a high concentration CS with the water content of 30%~40%. It has been reported [9,10] that as many as 15~20 kg CS can be obtained for every ton of steel produced.…”
