The industrial processing of avocado to extract oil, and produce guacamole or sauces generates enormous quantities of peels and seeds (around 2 million tons worldwide in 2019) without commercially valuable applications. However, various studies have suggested the presence of a wide range of interesting compounds in the composition of these by-products. This review depicts a thorough outline of the capacity of avocado residues to be converted into a portfolio of commodities that can be employed in sectors such as the food, cosmetics, pharmaceuticals, environment, and energy industries. Therefore, a novel biorefinery strategy to valorize avocado-processing residues to obtain a polyphenolic extract, pectooligosaccharides, and succinic acid was presented. Additionally, the prospects and challenges facing a biorefinery based on the valorization of avocado residues are presented, particularly its techno-economic feasibility on an industrial scale, aiming for a resource-efficient circular bio-economy.
牛油果的工业加工用于提取油、生产鳄梨酱或调味汁时会产生大量的果皮和果核（2019年全球约200万吨），这些产物没有商业上有价值的用途。然而，各种研究表明，这些副产品的成分中存在多种有趣的化合物。这篇综述全面概述了牛油果残渣转化为一系列商品的能力，这些商品可用于食品、化妆品、制药、环境和能源等行业。因此，提出了一种新颖的生物精炼策略，以利用牛油果加工残渣来获得多酚提取物、低聚果胶和琥珀酸。此外，还介绍了基于牛油果残渣增值的生物精炼面临的前景和挑战，特别是其在工业规模上的技术经济可行性，目标是实现资源高效的循环生物经济。
