Análise e tomada de decisão para avaliação de locais de produção de energia de biomassa com cana-de-açúcar no estado de Goiás

Abstract

The International Energy Agency indicates Brazil as the country with the greatest potential for bioenergy production, with sugarcane being a potential source of energy generation through biomass and the state of Goiás as the second largest producer of this grassy of Poaceae family in Brazil. In order to optimize the exploitation of this biomass resource for energy production, it is necessary to have a decision support system that, together with a Geographic Information System (GIS), can locate favorable areas for this application. The aim of this work was to identify sites for biomass energy production with sugarcane in the state of Goiás. Therefore, a decision support system by GIS was taken with the use of favorable and restrictive criteria related to technical, economic and environmental categories. Hence, after listing the favorable and unfavorable factors, fuzzy logic was applied and by the algebra of maps the data was crossed pointing out the areas suitable for energy generation from sugarcane biomass. The results have depicted that the state of Goiás has a suitable area for the production of biomass energy with sugarcane of 49001 km2, this corresponds to a proportion of 4.65 x 107 tons of sugarcane, with its residues it would be possible to generate 8.81 x 1013 Nm3 of biogas (more than the amount currently produced in Brazil) and generate 5.68 x 1014 kWh of electricity.
