Food loss and waste are major issues in the food industry, and they affect all stages of the food supply chain (FSC). Food loss and waste are linked to environmental deterioration, economic loss, and an increase in hunger. Therefore, the food industry requires sustainable consumption and production (SCP) to reduce losses and waste. The circular economy (CE) concept has become a popular strategy for reducing food waste and boosting sustainability. Therefore, with efficient reverse logistics in the FSC, food producers can help achieve sustainable development goals (SDGs) like SCP and zero hunger. In literature, minimal research has been available in identifying the CE adoption challenges in FSC. This research identifies 15 critical challenges from the literature and discussion with the panel of experts. The relationship between the challenges has been established through an interpretive structural modeling (ISM) technique. The challenges were characterized in cause–effect according to their relational intensity obtained using the grey decision-making trial and evaluation laboratory (DEMATEL) technique. Grey's relational theory is applied in DEMATEL to minimize uncertainty and vagueness of the expert judgment. The findings of this study suggest that creating policy from the government, providing incentives, and strictly enforcing environmental regulations are the most critical challenge. Hence, by focusing on the above, the effective adoption of the CE principle is achieved. This result also suggests that by addressing the challenges of CE, corporate social responsibility (CSR) can be performed. This study provides some recommendations for the practitioners to adopt CE towards sustainable development targets.

食品供应链中采用循环经济以促进可持续发展的挑战

粮食损失和浪费是食品行业的主要问题，它们影响食品供应链 (FSC) 的所有阶段。粮食损失和浪费与环境恶化、经济损失和饥饿增加有关。因此，食品行业需要可持续消费和生产（SCP）来减少损失和浪费。循环经济 (CE) 概念已成为减少食物浪费和促进可持续性的流行策略。因此，通过 FSC 中的高效逆向物流，食品生产商可以帮助实现可持续发展目标 (SDG)，例如 SCP 和零饥饿。在文献中，很少有研究可用于确定 FSC 中 CE 采纳的挑战。这项研究从文献和与专家小组的讨论中确定了 15 个关键挑战。挑战之间的关系已通过解释结构建模 (ISM) 技术建立。根据使用灰色决策试验和评估实验室 (DEMATEL) 技术获得的相关强度，挑战在因果关系中具有特征。DEMATEL 应用格雷的关系理论，最大限度地减少专家判断的不确定性和模糊性。这项研究的结果表明，政府制定政策、提供激励措施和严格执行环境法规是最关键的挑战。因此，通过关注上述内容，可以有效地采用 CE 原则。这一结果还表明，通过应对 CE 的挑战，可以履行企业社会责任 (CSR)。
