Brazilian Potential of Biogas Use as Fuels in Metallurgy: Process, Management and Costs

摘要

Biogas is the gas generated from degradation of organic material, based especially on methane. The methane is one of the Greenhouse Gas and contributes to this effect. To reduce this contribution, appear new ideas on renewable source of energy, and the use of biogas replacing a part of the material injected on blast furnaces in Iron and Steel making Industry is one of them. Brazil has a large herd animal, 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, the purpose of this paper is to show a solution for these two processes, thus mitigating the emission of polluting gases into the atmosphere. In this study, we noted that the use of agricultural wastes for production of biogas and the use of biogas as auxiliary fuel in blast furnaces. The study showed that Brazil has a great potential to transform the steel industry and agriculture, with a very good results on social and environment areas.
