Abstract:
Biomass is generated in agro industry and it was proved by some authors that the generation of residues is high and relevant to be used in the iron and steel making processes. In this sector there is interest to reduce the Green House Gas and biomasses appear as a new idea on renewable source of energy, replacing a part of the material injected on blast furnaces. Brazil has a huge production of biomass, for example, last year was produced around 300 Million ton of grains making it a major agricultural producers, while rich in natural resources. Brazil has an important role in the steel industry, these two activities now represent the largest contributors to greenhouse gases responsible for the greenhouse effect. Looking at this point, the purpose of this paper is analyze the technical, economic and environmental aspects of replacing part of the coal, commonly used in blast furnace, for some agribusiness waste as sugarcane bagasse, moringa oleifera husk and maize cob and straw. Some researches appointed that is possible to replace around 40% of the coal without change the process and bring some economics and environmental gains.
