The demands for fruits and processed products have significantly increased following the surging human population growth and rising health awareness. However, an enormous amount of fruit waste is generated during their production life-cycle due to the inedible portion and perishable nature, which become a considerable burden to the environment. Embracing the concept of “circular economy”, these fruit wastes represent sustainable and renewable resources and can be integrated into biorefinery platforms for valorization into a wide range of high-value products. To fully realize the potential of fruit waste in circular bioeconomy and provide insights on future commercial-scale applications, this review presented the recycling and utilization of fruit wastes in various applications, particularly focusing on pollutant bioremediation, renewable energy and biofuel production, biosynthesis of bioactive compounds and low-cost microbial growth media. Furthermore, the challenges of efficient valorization of fruit wastes were discussed and future prospects were proposed.

随着人口激增和健康意识的提高，对水果和加工产品的需求显着增加。然而，由于不可食用的部分和易腐烂的性质，在其生产生命周期中会产生大量的水果废料，这对环境造成了相当大的负担。采用“循环经济”的概念，这些水果废料代表了可持续和可再生资源，可以整合到生物精炼平台中，以增值为各种高价值产品。为了充分发挥水果废料在循环生物经济中的潜力并为未来的商业规模应用提供见解，本综述介绍了水果废料在各种应用中的回收利用，特别关注污染物的生物修复，可再生能源和生物燃料生产、生物活性化合物的生物合成和低成本的微生物生长培养基。此外，讨论了水果废料有效增值的挑战，并提出了未来前景。
