“…Due to their strong reactivity, tiny sizes, and outstanding surface functionality, IONPs perform very well as absorbents in wastewater treatment, according to the vast majority of nanomaterials research [ 240 , 241 ]. This development in the use of IONPs for waste remediation is based on their participation in magnetic particle generation, flocculation, and ionic and bio-separation processes [ 242 , 243 ]. The major limitations of IONP application for wastewater and environmental remediation are largely attributable to poor regeneration and reuse of the synthesized IONPs, lack of engagement of IONPs in green technology research, and increased treatment water filtration, modification of biosynthesized materials extraction due to their non-biodegradable nature, and increased treatment water filtration due to the highly insoluble nature of the ionized iron hydroxide (FeOOH) nanoparticle [ 244 – 246 ].…”

The significance of green synthesized nanomaterials with a uniform shape, reduced sizes, superior mechanical capabilities, phase microstructure, magnetic behavior, and superior performance cannot be overemphasized. Iron oxide nanoparticles (IONPs) are found within the size range of 1–100 nm in nanomaterials and have a diverse range of applications in fields such as biomedicine, wastewater purification, and environmental remediation. Nevertheless, the understanding of their fundamental material composition, chemical reactions, toxicological properties, and research methodologies is constrained and extensively elucidated during their practical implementation. The importance of producing IONPs using advanced nanofabrication techniques that exhibit strong potential for disease therapy, microbial pathogen control, and elimination of cancer cells is underscored by the adoption of the green synthesis approach. These IONPs can serve as viable alternatives for soil remediation and the elimination of environmental contaminants. Therefore, this paper presents a comprehensive analysis of the research conducted on different types of IONPs and IONP composite-based materials. It examines the synthesis methods and characterization techniques employed in these studies and also addresses the obstacles encountered in prior investigations with comparable objectives. A green engineering strategy was proposed for the synthesis, characterization, and application of IONPs and their composites with reduced environmental impact. Additionally, the influence of their phase structure, magnetic properties, biocompatibility, toxicity, milling time, nanoparticle size, and shape was also discussed. The study proposes the use of biological and physicochemical methods as a more viable alternative nanofabrication strategy that can mitigate the limitations imposed by the conventional methods of IONP synthesis.

The blast furnace and direct reduction processes have been the major iron production routes for the past few decades, but the challenges of maintaining the iron and steel-making processes are enormous. The challenges, such as cumbersome production routes, scarcity of metallurgical coke, high energy demands, and a high cost of production, cannot be overemphasized. This study provides a systematic overview of the different ironmaking routes, and the challenges involved. Subsequently, strategic ways towards improving the production efficiency and product quality of metallic iron produced in the recent iron processing routes were suggested. The study reiterated that the non-contact direct reduction and reduction-smelting routes are the faster ironmaking and steelmaking processes that can utilise alternative energy sources efficiently with little or no carbon deposition. Both processes also have promising features based on their requirements in terms of fewer energy demands, time-saving, cost-effectiveness, and operational efficiency. Thus, in today's iron and steelmaking processes, non-contact direct reduction and reduction-smelting processes remain viable alternative iron production routes.
