Acesso em:.https://bdm.ufpa.br/jspui/handle/prefix/7968The steel industry is one of the largest sources of CO₂ emissions, primarily due to the traditional blast furnace process used to produce pig iron, which relies on mineral coal. This process significantly contributes to greenhouse gas emissions. With increasing demands for emission reductions, sustainable alternatives such as Tecnored have gained prominence. This study compared the traditional blast furnace iron production process with the Tecnored technology, considering environmental, operational, and economic aspects. An integrative literature review was conducted, analyzing studies from databases such as Web of Science, Scopus, Science Direct, and acadêmico, focusing on the environmental implications of each process. The analysis showed that, despite the blast furnace’s efficiency in large-scale production, it remains a major CO₂ emitter. In contrast, Tecnored stands out for its ability to reduce CO₂ emissions by up to 50%, using biomass and industrial waste as substitutes for coke, and it is more flexible with lower infrastructure requirements, making it a viable option for new installations. This study emphasizes the need for the adoption of low-carbon technologies, such as Tecnored, for the steel industry to meet global decarbonization and sustainability goals. However, large-scale adoption depends on further industrial validations and public policies that promote the transition to more sustainable practices.Acesso AbertoSiderurgiaEmissões de CO2Alto-fornoSteel industryCO₂ emissionsBlast-furnaceCNPQ::ENGENHARIAS::ENGENHARIA DE MATERIAIS E METALURGICA::METALURGIA DE TRANSFORMACAO::TRATAMENTO TERMICOS, MECANICOS E QUIMICOSTrabalho de Curso - Graduação - Monografia
