This article analyses the national policies and initiatives related to the production, research and development of the second generation ethanol (E2G) in Brazil. Using actor-network theory as the theoretical and methodological referential, we sought to identity, from a bibliographical and documentary survey, which are the policies interwoven with E2G, the main actors that form this network, its alliances, the related technologies and the main issues involved in this process. By mapping this network and tracking its controversies, we try to demonstrate how E2G is still a black box open to human and non-human actor associations, policies and (in)definitions. Finally, we point out the implications of this artefact with its related policies, seeking to contribute to the current debate on energy policy and Brazilian science and technology.
