Food waste is a global sustainability issue that demands several stakeholders to participate in solving it. This article examines how different food system stakeholders are held responsible in the policy debate related to food waste reduction. The study adopts a framing approach, paying attention to the construction and negotiation of what is going on in the food waste related public policy debate. The data consist of documents generated as a result of food policy development processes in Finland. The authors identify four framings: eco-efficiency, solidarity, safety and appreciation. Within each framing, the issue of food waste is presented differently, and different stakeholders are responsibilized. The framings reveal the nature of food waste as a boundary object, a flexible and open-ended object that gains different context-dependent meanings. The study extends marketing literature on responsibilization by investigating several stakeholders besides consumers. Additionally, considering food waste as a boundary object unravels how stakeholders, even those with conflicting interests, can debate policy measures collaboratively. Finally, the authors outline policy implications related to each framing.

厨余是一个全球性的可持续性问题，需要多个利益相关者参与解决。本文探讨了与减少食物浪费有关的政策辩论中不同的食物系统利益相关者如何承担责任。该研究采用框架化方法，关注与食物垃圾相关的公共政策辩论中正在发生的事情的构建和谈判。数据包括由于芬兰食品政策制定过程而生成的文件。作者确定了四个框架：生态效率，团结，安全和赞赏。在每个框架中，食物浪费的问题都以不同的方式提出，并且由不同的利益相关者负责。框架揭示了食物垃圾作为边界对象的性质，这是一种灵活且开放式的对象，具有不同的上下文相关含义。该研究通过调查除消费者之外的几个利益相关者，扩展了有关责任的市场营销文献。此外，将食物浪费视为一个边界对象，揭示了利益相关者（甚至利益冲突的利益相关者）如何协作讨论政策措施。最后，作者概述了与每个框架相关的政策含义。
