Abstract

The United Nations Environment Programme’s (UNEP’s) Food Waste Index Report 2021 highlights a global annual food waste of 1 billion tons. The UNEP plays a crucial role in achieving Sustainable Development Goal (SDG) 12.3, which aims to halve per capita global food waste (FW) at the retail and consumer levels and reduce food losses along production and supply chains globally by 2030. On the other hand, the agricultural sector faces the challenge of increasing productivity to feed the world’s growing population while reducing the environmental impact on ecosystems and human health. In this context, the conversion of agri-food waste (AFW) into biocides, bio-based fertilizers (BBFs) and biostimulants could represent a successful approach to tackle all these issues. This review shows the latest findings on the different sources of AFW and the application of their bioactive compounds in agriculture. Increasing crop yields and improving plant physiology through the utilization of AFW-derived value products aligns with a circular economy approach, bolstering people’s confidence in managing food waste for improved food production.

释放农业食品废弃物的潜力，促进农业可持续创新

联合国环境规划署（UNEP）发布的《2021 年食物浪费指数报告》指出，全球每年浪费的食物达 10 亿吨。环境署在实现可持续发展目标（SDG）12.3方面发挥着至关重要的作用，该目标旨在到2030年将全球零售和消费者层面的人均食物浪费（FW）减半，并在全球范围内减少生产和供应链中的食物损失。另一方面，农业部门面临着提高生产力以养活全球不断增长的人口，同时减少对生态系统和人类健康的环境影响的挑战。在这种情况下，将农业食品废弃物（AFW）转化为生物杀灭剂、生物基肥料（BBF）和生物刺激剂，可能是解决所有这些问题的成功方法。本综述介绍了有关农业食品废弃物不同来源及其生物活性化合物在农业中应用的最新研究成果。通过利用厨余垃圾衍生的有价值产品来提高作物产量和改善植物生理机能符合循环经济的方法，增强了人们管理厨余垃圾以提高粮食产量的信心。
