“…The creation of biochar offers an exceptional chance for the steel industry to apply circular economy principles. Biochar can be created as a usable product using biomass waste, such as wood scraps and agricultural wastes, for steel-making purposes (Dermawan et al 2022 ; Selvarajoo et al 2022 ; Tan 2023 ). This reduces the price of waste/residue disposal while simultaneously optimizing resource use and promoting economic models that are driven by sustainability.…”

“… Reducing agent: Biochar can be used as a reducing agent as a substitute for conventional carbon-based sources like coal (Dermawan et al 2022 ; Selvarajoo et al 2022 ; Tan 2023 ). It can serve as a reducing agent in direct reduction or blast furnace iron-making to convert iron oxides into metallic iron.…”

Integrating innovation and environmental responsibility has become important in pursuing sustainable industrial practices in the contemporary world. These twin imperatives have stimulated research into developing methods that optimize industrial processes, enhancing efficiency and effectiveness while mitigating undesirable ecological impacts. This objective is exemplified by the emergence of biochar derived from the thermo-chemical transformation of biomass. This review examines biochar production methods and their potential applications across various aspects of the iron and steel industries (ISI). The technical, economic, and sustainable implications of integrating biochar into the ISI were explored. Slow pyrolysis and hydrothermal carbonization are the most efficient methods for higher biochar yield (25–90%). Biochar has several advantages- higher heating value (30–32 MJ/kg), more porosity (58.22%), and significantly larger surface area (113 m2/g) compared to coal and coke. However, the presence of biochar often reduces fluidity in a coal-biochar mixture. The findings highlighted that biochar production and implementation in ISI often come with higher costs, primarily due to the higher expense of substitute fuels compared to traditional fossil fuels. The economic viability and societal desirability of biochar are highly uncertain and vary significantly based on factors such as location, feedstock type, production scale, and biochar pricing, among others. Furthermore, biomass and biochar supply chain is another important factor which determines its large scale implementation. Despite these challenges, there are opportunities to reduce emissions from BF-BOF operations by utilizing biochar technologies. Overall, the present study explored integrating diverse biochar production methods into the ISI aiming to contribute to the ongoing research on sustainable manufacturing practices, underscoring their significance in shaping a more environmentally conscious future.

“…The parameter n is 1.82, indicating a favorable adsorption since it falls within the range of 1 to 10. Moreover, values of n above 1 suggest a stronger adsorption force on the active sites of the adsorbent(Oumabady et al 2022;Dermawan et al 2022). Consequently, chemisorption predominates in this adsorption process, leading to the conclusion that the plasma treatment with uoride enhances the adsorption capacity of mercury.…”

Metal ion adsorption using agro-industrial residues has shown promising results in remediating contaminated waters. However, adsorbent effectiveness relies on their properties, often necessitating processing for modification. Considering this, plasma treatment is effective in modifying material surfaces physically and chemically. This study investigated the modification of sugarcane bagasse (SB) using plasma-treated and evaluated its efficacy as a novel adsorbent for mercury removal from aqueous solutions. SB underwent low-temperature plasma treatment with sulfur hexafluoride (SF6) as the working gas, varying treatment times (2, 30, and 60 minutes) and fixed powers (80, 190, and 300 W) at 16 Pa pressure. Characterization via scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS/SEM), Fourier transform infrared spectroscopy (FTIR) and zero point of charge (pHpzc) revealed significant structural changes like increased in porosity and alteration in proportion atomic. Additionally, the successful incorporation of fluorine was confirmed in all treatment conditions, while sulfur was detected in only some samples. Amongst the tested conditions, the SB treated with 300 W for 60 minutes demonstrated the highest mercury removal efficiency, achieving an impressive 83.67% removal rate compared to untreated SB, which yielded only 57.95%. The adsorption mechanism exhibited both physical and chemical behavior, with chemisorption being the dominant process. The Freundlich model provided the best fit to the experimental data, with an R2 value of 0.97. In conclusion, plasma treatment can be a promising alternative for improving the physical and chemical characteristics of SB adsorbents, thereby improving their efficiency in removing mercury from aqueous solutions.
