Circular Economy (CE) aims to retain the maximum value of products and materials for a longer time in a closed-loop manner, thereby decoupling natural resource usage from economic growth. Food waste reduction is one of the top priorities under the recent European Union's CE Package. It also contributes to achieving the United Nations' Sustainable Development Goals (SDG 12.3). While food loss and waste (FLW) prevention and management are well-studied in the literature, research in CE is more recent. Through a systematic literature review, this study creates a taxonomy that synthesises the key aspects of FLW under the CE. 297 papers were reviewed and analysed using keyword co-occurrence analysis (KCN) and structural dimension analysis. In KCN, three research themes emerge: impact assessment, biorefinery, and nutrient recycling. Structural dimension analysis reveals the types of research methods, types of FLW flows, FLW prevention and management options with associated opportunities and challenges, and the sustainability impact assessment (SIA) addressed in the literature. A taxonomy is presented and future research directions are highlighted under six research streams: i) FLW supply and quantification, ii) practices and technological aspects, iii) logistics and supply chain management, iv) market demand, v) SIA, and vi) policy and legislation. Combining insights from CE and FLW prevention and management, the taxonomy helps key stakeholders, including industry practitioners to grasp new business opportunities, politicians to set up support strategies and strategic development plans, society to recognise the benefits of waste-oriented bioeconomy, and consumers to raise their awareness and be actively involved in CE.

循环经济（CE）旨在以闭环方式更长时间地保留产品和材料的最大价值，从而使自然资源的使用与经济增长脱钩。减少食物浪费是最近欧盟 CE 一揽子计划的首要任务之一。它还有助于实现联合国的可持续发展目标（SDG 12.3）。虽然文献中对食物损失和浪费 (FLW) 的预防和管理进行了深入研究，但 CE 的研究是最近的。通过系统的文献回顾，本研究创建了一个分类法，综合了 CE 下 FLW 的关键方面。使用关键字共现分析 (KCN) 和结构维度分析对 297 篇论文进行了审查和分析。在 KCN，出现了三个研究主题：影响评估、生物精炼和养分循环。结构维度分析揭示了研究方法的类型、FLW 流动的类型、具有相关机遇和挑战的 FLW 预防和管理选项，以及文献中提到的可持续性影响评估 (SIA)。提出了一个分类法，并在六个研究方向下强调了未来的研究方向：i) FLW 供应和量化，ii) 实践和技术方面，iii) 物流和供应链管理，iv) 市场需求，v) SIA 和 vi) 政策和立法。该分类法结合了 CE 和 FLW 预防和管理的见解，帮助关键利益相关者，包括行业从业者把握新的商机，政治家制定支持战略和战略发展计划，社会认识到以废物为导向的生物经济的好处，
