The case study addresses the feasibility of using innovative energy technologies, such as biomass/biochar, agricultural residues, solid waste and urban effluents, as alternatives to charcoal in integrated steel plants that use coke. Using the CarbSteeler software developed by PSR, this study serves as a model for other plants in the country, aiming to improve the understanding of relevant innovative technologies, energy sources and crucial variables in the assessment of the economic and technical feasibility of adopting different raw materials and in the continuous development of projects.
