摘要：

Food waste generation is an unavoidable issue due to the increase in the human population and economic growth worldwide. Therefore, it is crucial to explore various eco-friendly and sustainable waste management practices to reduce these environmental impacts while creating value-added products derived from these food waste resources. The cultivation of microalgae can contribute to the global carbon neutrality process and help reduce the emission of greenhouse gases into the environment. However, several concerns such as food safety, quality, social acceptability, and the perception of using food waste to cultivate microalgae remain uncertain in the current food waste management. This review provides a comprehensive assessment of the biochemical mechanisms involved in the metabolization process of microalgae, assimilating organic compounds derived from food waste sources and emphasizing the importance of understanding these complex processes. This review also explores the intricate relationships among the variations in food waste composition, hydrolysis processes, and nutrient bioaccessibility during cultivation of microalgae. Furthermore, we conducted a thorough evaluation of technoeconomic analyses and life cycle assessments from various literature sources, highlighting several key elements such as the economic feasibility and environmental impacts of producing microalgae biomass from food waste. Finally, this review summarizes the future outlook and way forward in upcycling food waste with microalgae biotechnology by providing several recommendations for improvement.
