SECOND GENERATION ETHANOL IN BRAZIL: POLICIES AND SOCIO-TECHNICAL NETWORKS

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.本文针对巴西第二代乙醇（E2G）的生产、研发相关国家政策与举措展开分析。本研究以行动者网络理论（Actor-Network Theory）作为理论与方法参照框架，通过文献与档案调研，旨在厘清与E2G相互交织的各项政策、构成该网络的核心行动者、其间的联盟关系、关联技术，以及该进程中涉及的核心议题。通过绘制该网络图谱并追踪其争议脉络，本研究旨在阐明E2G至今仍是一个可被人类与非人类行动者关联、政策干预，以及各类（非）定义所打开的黑箱。最后，本文探讨了该技术产物与其关联政策之间的交互影响，以期为当前能源政策及巴西科技领域的相关学术讨论提供有益参考。
