Economical feedstocks such as agricultural wastes, food and waste cooking oil were used for biodiesel production to expand their application. Thus, a solid base catalyst was synthesized from mixture of ripe unripe plantain peels at calcination temperature 500 °C 4 h. The characterized using Scanning Electron Microscope (SEM), X-ray Diffraction (XRD) analysis, Fourier Transform Infrared (FT-IR) spectroscopy, Energy dispersive (EDX) Brunauer-Emmett-Teller (BET) method. (WCO) in this study first pretreated with 3% (v/v) H2SO4 via esterification reaction due its high acid value. esterified WCO converted transesterification reaction, the process then modeled optimized Taguchi L9 orthogonal array design method considering temperature, time, amount, methanol/WCO molar ratio input variables. Based on results, predominantly contained potassium phases 45.16 wt.%. morphology revealed crystalline mesoporous nanocomposite. At end esterification, acidity decreased 5 1 mg KOH/g. optimal conditions established amount 0.5 wt.%, 6:1, 45 °C, time min corresponding yield 97.96 quality produced satisfied specifications (ASTM D6751 EN 14,241) recommended fuels. Hence, blend could serve an efficient heterogeneous producing WCO.
