“…The seed oil of P. maderaspatensis was successfully transesterified using methanol and green nano Cr 2 O 3 catalyst (Figure 4). The seeds of P. maderaspatensis seeds possess very low FFA content (0.8722 mg KOH g −1 ), thus allowing a single‐step transesterification reaction (Athar et al., 2022). The highest biodiesel yield of 92% was achieved under ideal conditions, thus confirming the suitability of feedstock to overcome energy issues.…”

This study explores the sustainable production of biodiesel from nonedible Phyllanthus maderaspatensis seed oil (highest oil content of 35%, FFA 0.87 mg/KOH), utilizing an innovative green synthesis approach for chromium oxide nanoparticles derived from the waste fruit parts of Aubergine for the very first time in the current work. In pursuit of alternatives to fossil fuels, our research underscores the environmental and socio‐economic benefits of biofuels, particularly in reducing greenhouse gas emissions. The optimized process yielded a 92% biodiesel conversion under conditions of a 9:1 methanol‐to‐oil ratio, 0.135 wt.% catalyst concentration, and a reaction duration of 150 min at 80°C. Comprehensive analysis techniques, including XRD, FTIR, SEM, EDX, Zeta analysis, differential reflectance spectroscopy (DRS), GC–MS, and NMR (1H, 13C), were employed to characterize the synthesized nanocatalyst and biodiesel product. The biodiesel's fuel properties, such as acid value, fire point, pour point, viscosity, kinematic density, sulfur content, and cloud point, were rigorously tested, demonstrating compliance with international standards (ASTM D‐6571, EN 14214, and GB/T 20828‐2007). The use of P. maderaspatensis seed oil, an economical and environmentally friendly feedstock, in conjunction with a cost‐effective nanocatalyst, presents a viable pathway for the sustainable and scalable production of biodiesel. This study contributes to the advancement of bioproducts for a sustainable bioeconomy by demonstrating an integrated approach to bioenergy production that leverages biotechnological innovations and addresses both environmental and socio‐economic dimensions.

“…4(b). 98 Dielectric loss results in microwave dielectric heating, which is a bulk effect. Thus, dielectric heating by irradiation with microwave energy at 2.45 GHz is made feasible by multiple species in the reaction mixture having a persistent dipole, for instance, methanol in the trans-esterication reaction.…”

“…This method is effective for the simultaneous conversion of FFA and oil (triglyceride) into biodiesel; however, its industrial application is limited because of the high cost of enzymes required in this process [14]. Transesterification using supercritical fluids [15], microwave-assisted techniques [16], and ultrasoundassisted techniques [17] have also been developed for biodiesel production. Although these methods help ensure a high biodiesel yield at a short reaction time, they retain several problems such as extremely high pressure (>20 MPa) and temperature (>300 °C) of supercritical fluids, difficulty to scale up of microwave and ultrasound techniques, thus limiting their industrial applications [18,19].…”

Electrolysis is a promising approach for biodiesel production. However, low electrical conductivity of a reaction mixture results in a low reaction rate. Thus, this study developed a novel catalyst-free electrolysis process using an ionic liquid as a supporting electrolyte for biodiesel production. Various ionic liquids were assessed, and 1-ethyl-3-methylimidazolium chloride ([Emim]Cl) exhibited the highest electrical conductivity (4.59 mS/cm) and the best electrolytic performance for transesterification. Electrolysis in the presence of [Emim]Cl was subsequently optimized using response surface methodology to maximize biodiesel yield. A maximum biodiesel yield of 97.76% was obtained under the following optimal reaction conditions: electrolysis voltage, 19.42 V; [Emim]Cl amount, 4.43% ( w / w ); water content, 1.62% ( w / w ); methanol to oil molar ratio, 26.38 : 1; and reaction time, 1 h. Notably, [Emim]Cl could be efficiently reused for at least three cycles with a corresponding biodiesel yield of 94.81%. Moreover, the properties of the synthesized biodiesel complied with EN and ASTM standards. The findings of this study indicate that catalyst-free electrolysis using [Emim]Cl as a supporting electrolyte is an eco-friendly and efficient method for biodiesel production.
