This paper adopts the approach of neo-schumpeterian innovation systems to characterize the Sectorial System of Biodiesel in Rio Grande do Sul, Brazil. Based on this approach, it was examined the possible interactions that take place between biodiesel companies in the state and other agents such as universities and research institutes. The study was conducted by the systematization of a secondary set data from different sources. In addition, to obtainprimary data, interviews were conducted guided by a structured questionnaire. It was found that firms innovate narrowly, implementing technological innovations exclusively in process and realizing organizational changes. It was also found that the institutional apparatus research and educational in this state, while generating important knowledge, interacts little with the private productive sector.
