Increasing waste production is a serious problem for every country with substantial waste management initiatives. This challenge can be addressed by establishing waste reduction as a strategic policy. To this end, a project prioritizing community-based composting was implemented in Vietnam’s Thua Thien Hue province. The project mandated that the actors involved (i.e., local authorities, assistance groups, and residents) separate out organic waste for composting. To understand more fully how this policy could be implemented more successfully, first, the present study examined the links between local authorities’ support, groups providing assistance to residents during initiatives, and the project’s outcomes. Second, the research focused on the autonomous motivations influencing this project. These two points made our study novel. A case study design was applied based on self-determination theory and an adapted institutional analysis and development framework. Content analyses of qualitative and secondary data were conducted to examine the framework’s relevant components. Focusing on the psychological states approach, results showed that autonomous motivation was the main driver of waste separation and was activated by the local authorities’ autonomy support, deployed via an assistance group consisting of a waste collector and village leader, as well as other community attributes. These factors therefore affected the project’s outcomes. The research demonstrates the need to advocate local authorities’ autonomy support and residents’ autonomous motivation for waste separation.

成功实施废物管理政策的自主动机：在越南 Thua Thien Hue 使用调整后的制度分析和发展框架进行的检查

对于每个拥有大量废物管理计划的国家来说，增加废物产生都是一个严重的问题。可以通过将减少废物作为一项战略政策来应对这一挑战。为此，在越南的 Thua Thien Hue 省实施了一个优先考虑社区堆肥的项目。该项目要求相关参与者（即地方当局、援助团体和居民）将有机废物分离出来用于堆肥。为了更全面地了解如何更成功地实施这项政策，本研究首先考察了地方当局的支持、在倡议期间向居民提供援助的团体以及项目成果之间的联系。其次，研究集中在影响该项目的自主动机上。这两点使我们的研究变得新颖。基于自决理论和适应的制度分析和发展框架应用了案例研究设计。进行了定性和辅助数据的内容分析，以检查框架的相关组成部分。关注心理状态方法，结果表明自主动机是垃圾分类的主要驱动力，由地方当局的自主支持激活，通过由垃圾收集者和村长组成的援助小组以及其他社区属性进行部署. 因此，这些因素影响了项目的结果。研究表明，需要倡导地方当局的自治支持和居民对垃圾分类的自治动机。
