“…Compared to other processes like fast pyrolysis and gasification, which may prioritize the generation of bio-oil or syngas, hydrothermal carbonization, and slow pyrolysis are recognized for generating larger biochar yields (Salimbeni et al 2023 ). These results aligned with the reports of Abhi et al ( 2023 ); Safarian ( 2023a ), which revealed that slow pyrolysis and HTC are the most effective techniques for producing high-yielding biochar, with yields that vary from 25 to 90 weight%, and even more subject to the reactor type, feedstock, and operating circumstances. This finding was corroborated by another study, which showed that for each of the various applications, including recarburizing in steel-making, coal blend for coke-making, coke breeze for sintering, coal injectant for the BF, the characteristics of biochars generated through pyrolysis of biomass can be customized, enabling optimum efficiency and greater usefulness of the char (Jahanshahi et al 2014 ).…”

“…The ISI can help in carbon capture efforts by adding biochar-enriched soils into their operation, compensating its CO 2 emissions, and supplementing the general climate change alleviation plans. Waste management: The production of biochar from industrial, domestic, agricultural, livestock, forest, and municipal solid wastes, among others, serves as a waste management technique (Abhi et al 2023 ; Xu et al 2021 ). Several studies on generating biochar form wastes/residues have been reported in the literature.…”

“…Biochar comprehensively addresses climate change, ranging from its function in soil enrichment to its potential integration inside the steel industry, a classic sector distinguished by its significant carbon footprint and complex manufacturing methods (Abhi et al 2023 ; Azzi et al 2022 ). In light of this context, the steel sector is a top prospect for creative biochar integration.…”

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.

Steel is an essential material in modern infrastructure and industry, but its production is associated with significant carbon dioxide emissions. Biocarbon utilization in electric arc furnace (EAF) steelmaking represents a promising pathway toward reducing the carbon footprint of steel production. This review draws new perspectives on the current state of biocarbon utilization in EAF steelmaking by collectively examining the literature from multiple scales of testing, from laboratory experiments to industrial trials. The scientific insights from each scale are defined and the results are collectively pooled to give a comprehensive understanding of biocarbon’s performance for EAF applications. Several recent progressions are identified along with critical limitations, such as biocarbon’s high reactivity or low density. However, solution pathways like agglomeration are established from the thorough understanding developed by this study. These insights aim to enhance the progression of biocarbon utilization in the EAF process, ultimately facilitating the development of more efficient and sustainable steelmaking. The proposed areas for future research, such as optimizing key biocarbon properties or improved injection systems, are expected to have significant impact on the next phase of biocarbon adoption.
