Resumo
O presente trabalho objetivou analisar o fluxo energético considerando as rotas atualmente existentes para o escoamento de soja da região centro-oeste do Brasil, mais precisamente, do município de Rio Verde (GO) até o porto de Santos (SP), visto que, é um grande pólo exportador de granéis sólidos. Foram selecionadas duas rotas para a análise, uma contemplando a multimodalidade, ou seja, os modais rodoviário, ferroviário e hidroviário, e outra, uma única modalidade, o modal rodoviário. A conversão dos fatores físicos e operacionais envolvidos nos sistemas logísticos, multimodal e unimodal de transportes estudados se deu por meio de coeficientes energéticos levantados junto à literatura. Os resultados obtidos indicaram, pela rota 1 multimodal, com gasto energético específico maior o modal rodoviário (0,50 MJ.km-1.t-1), seguido pelo modal ferroviário (0,42 MJ.km-1.t-1) e, em terceiro, o modal hidroviário (0,22 MJ.km-1.t-1). Pela rota 2 unimodal rodoviário, o resultado indicou 0,50 MJ.km-1.t-1. Nas participações de energia apresentadas, comparando as rotas 1 e 2, a que apresentou maior gasto energético específico foi a rota 2 (0,50 MJ.km-1.t-1), seguida pela rota 1 (0,34 MJ.km-1.t-1).
The present work objectified to currently analyze the energy flow considering the existing routes for the draining of soy of the region center-west of Brazil, more necessarily, of the city of Rio Verde (GO) until the port of Santos (SP), since, it is a great exporting polar region of solid granaries. Two routes for the analysis had been selected, one contemplating the multimodality, that is, modal the road, together railroad worker and water road, and another one, an only modality, the modal road. The conversion of involved the physical and operational factors in the systems logistic, multimodal and unimodal of studied transports if gave by means of raised energy coefficients next to literature. The gotten results had indicated, for multimodal route 1, with energy expense specific greater the modal road (0,50 MJ.km-1.t-1), followed for modal railroad worker (0,42 MJ.km-1.t-1) e, in third, the modal water road (0,22 MJ.km-1.t-1). For route 2 road unimodal, the result indicated 0,50 MJ.km-1.t-1. In the presented participation of energy, comparing routes 1 and 2, the one that specific energy expense presented greater it was route 2 (0,50 MJ.km-1.t-1), followed for route 1 (0,34 MJ.km-1.t-1).
