“…reported 2.1 mm 2 /s which is a unique value for the same type of fruit. As reported by Almasi et al 190 . and Ezekoye et al ., 185 the reported kinematic viscosity of biodiesel from bitter orange and Citrus sinensis seed oil are within the ASTM standard (as indicated in Table 12) and conventional diesel (2–4.5 mm 2 /s at 40 °C).…”

“…on the physicochemical properties of biodiesel produced from bitter orange seed oil showed good compliance with ASTM standards. As Table 12 shows, the density of bitter orange biodiesel, which is an important parameter that determines the atomization of fuels in an airless combustion system, complies with ASTM and EN standards and is also less than that of biodiesel from rapeseed (0.8825 g/cm 3 ) and moringa (0.883 g/cm 3 ) 190 . The kinematic viscosity, which causes incomplete combustion, carbon deposition, and smoke exhaust in the engine and affects the overall performance and emission of the engine whenever beyond the limit, is also in agreement with ASTM for biodiesel produced from better orange oil 190 .…”

According to the author's 190 findings, bitter orange oil is a potential new feedstock to produce biodiesel that can be used in a diesel engine because the values of other physicochemical properties are in good agreement with the ASTM requirement, as seen in Table 12.…”

“…For instance, biodiesel production from citrus seed oil is gaining attention due to its fatty acid composition and low cost in comparison with other vegetable oils 25 . Almasi et al 190 . reported that bitter orange ( Citrus aurantium ) seed oil can be used as a novel feedstock for biodiesel production, and a maximum yield of 97% was obtained via a base‐catalyzed transesterification reaction at 60 °C, 1 wt.% catalyst concentration, and an 8:1 methanol to oil ratio.…”

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.
