Abstract: The search for renewable sources of energy has been increasing the global demand for ethanol. Brazil is the second largest ethanol producer in the world. The increase in oil prices, the strong demand for clean and renewable sources of energy, and the intense commercialization of flex-fuel cars have created a very favorable scenario for biofuel production, including ethanol. Furthermore, ethanol has environmental advantages, as its combustion generates less carbon dioxide than gasoline. However, the growing demand for ethanol requires substantial investments in storage/tankage units at strategic locations and a transport structure that is compatible with the growing production and consumption of this fuel. In Brazil, ethanol is produced in the plants and transferred to collection centers for storage. Sometimes, the product could be directly transferred to the distribution base. This process is mostly carried out by road transport mode. However, currently, the country faces the risk of a logistics blackout as well as challenges regarding storage and transportation capacity, that end up affecting product competitiveness compared to major global players. Objective: The purpose of this study is to analyze ethanol transportation alternatives in the face of current logistics conditions in Brazil. We propose a partial equilibrium model in the form of a Mixed Complementarity Problem (MCP) applied to ethanol. Two scenarios are examined: the first concerns a base scenario comprising road and multimodal transport with the currently charged freight and the second involves an estimated 15% decrease in railroad freight. Results: Scenario 2 shows relatively favorable trading volumes when compared with the base scenario. We also highlight that multimodality assumptions in scenario 2 resulted in competitiveness gains in the international market, this because 100% of the routes destined for the foreign market are multimodal routes. Conclusion: Transport systems that prioritize multimodality imply transportation cost reductions and improve the efficacy of the logistics system.
