Proposing a model to evaluate the biodiesel suppliers and optimizate the cost transportation in biodeisel productive chain based in sustainability criteria

Observa-se uma demanda mundial crescente por energias ditas renovÃveis. Dentre estas energias, encontra-se o biodiesel, que à derivado de biomassa renovÃvel. PorÃm, para que esta cadeia seja competitiva, ela deve satisfazer a alguns critÃrios de competitividade. Existe tambÃm a possibilidade de exportaÃÃo deste combustÃvel, porÃm, à necessÃrio que sejam seguidas algumas diretrizes que estÃo sendo elaboradas para certificaÃÃo da cadeia de valor dos biocombustÃveis, baseado em critÃrios de sustentabilidade. Assim, a presente dissertaÃÃo tem por objetivo apresentar um modelo de seleÃÃo de fornecedores para as usinas de biodiesel, levando em consideraÃÃo os critÃrios de certificaÃÃo e competitividade identificados na cadeia. Para tanto, foi utilizada a metodologia SMARTER para a realizaÃÃo deste modelo. Este modelo foi agregado em conjunto com um modelo de otimizaÃÃo de transporte para a minimizaÃÃo dos custos envolvidos. Observou-se que o modelo apresenta aumento no custo de transporte, se forem levadas em consideraÃÃo as imposiÃÃes de selo social do governo federalNowadays, it is observed a world demand for renewable energies. This kind of energy must be sustainable to be considered renewable. Nowadays, the consumption of diesel is growing up and it emits greenhouse gas. To reduce this kind of emission, one alternative is biodiesel. But, when we talk about biodiesel, there are some challenges to be upper. This first one is that this chain must be competitive. There are some criteria to evaluate the chainsâ competitiveness. It was observed too, that Brazil has a big potential to export this kind of fuel. However, some countries are developing some norms to evaluate if this fuel is sustainable and if it has positives impacts in the society. The present work create a model do evaluate biodiesel chain suppliers using competitiveness and certification criteria identify in this chain. To this, was used the SMARTER methodology. This model was putted together a transport optimization model. It could be observed that the âselo socialâ has an important impact in transportation costs. When were evaluated the competitiveness and certification evaluation models we could see that this suppliersâ evaluation model change this relationship
