Global energy demand is expanding due to an increasing population and the use of energy‐intensive technologies. Fossil‐based energy and transportation sectors have been blamed for greenhouse gas emissions and price fluctuations. Biofuel production has been suggested as a possible solution to this problem, despite the cost of production and difficulties with the availability of feedstocks, and the food versus energy debate, which is still a challenging issue. For many decades, researchers have been investigating how to valorize low‐cost and non‐edible biomass resources, including fruit‐processing waste and its byproducts, to produce various biofuels using innovative, cost‐effective, and green technologies to overcome these challenges. However, exhaustive studies and comprehensive and structured knowledge related to the biofuel production potential of fruit waste and byproducts are lacking because most of the research that has been done so far was specific to a single fruit, location, and method. As a result, this review paper emphasizes the evaluation of the physicochemical compositions of the wastes and byproducts derived from tropical fruit production and processing to determine their suitability in the production of different biofuels via various valorization techniques. The results of the review showed that fruit waste is a potential alternative raw material for producing different biofuels, like biodiesel, biogas, biohydrogen, and fuel pellets.

In response to the imperative to address food and agricultural waste and promote environmental sustainability, this study investigates the transformation of watermelon rind waste into a valuable resource. We extract polyphenols and antioxidants from freeze-dried watermelon rind across four cultivars (Crimson Sweet, Black Prince, Black Chairman, and Sugar Baby) using ultrasound-assisted extraction. Solvent selection, based on a preliminary experiment, was optimized through the response surface methodology (RSM), fine-tuning the solvent concentration and sonication time. The RSM effectively modeled our responses (R 2 > 0.90), confirming its suitability for optimization. Applying the optimized parameters (80% solvent concentration and 20 min of sonication) to the rinds yielded extracts rich in flavanols (10−30 mg/g) and phenolics (1−2.5 mg/g), with high DPPH (22−40 mg Trolox/g) and FRAP (26−42 mg ferrous sulfate/g) antioxidant activities. Furthermore, fatty acid and phytosterol profiles of watermelon rinds were reported, demonstrating their potential applications in food, pharmaceuticals, nutraceuticals, and industry.

Watermelon (Citrullus lanatus) is a popular fruit worldwide due to its refreshing taste and its high water content (92% of its weight). According to the phytochemistry of the plant, carbohydrates, saponins, glycosides, steroids, alkaloids, polyphenols, flavonoids, and tannins can be detected in watermelons. C. lanatus generates by-products and, as such, can be characterized by its seeds and rinds. These by-products’ phytochemicals are nutritious and functional. Watermelon seeds contain many phytochemical compounds with beneficial biological activities, according to numerous scientific studies. This fact promotes watermelon seed consumption and encourages food and pharmaceutical companies to use this innovative ingredient. The watermelon rind has all the nutrients of the pulp and also more antioxidants, minerals, vitamins, and bioactive substances. Numerous studies show that watermelon peel is high in fiber and nutrients and can be used in a variety of culinary products. These residues need to be utilized for creating innovative functional food products with added value for the food chain’s sustainability. More studies of watermelon by-products are required to promote functional food, nutraceutical, and pharmaceutical applications. This review aims to shed light on the underutilized portion of watermelon and its chemical properties in order to pave the way for future research.
