This study investigates the use of bean husks as a precursor for synthesis an efficient and regenerable catalyst, with aim offering economical sustainable alternative biodiesel production. Residual shell biomass (RBBH) was calcined at different temperatures (350-500 °C) times (1-4 h) to determine optimum conditions. The catalyst obtained characterized by various methods, such X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), Energy Dispersive (EDS) Thermogravimetric Analysis (TG/DTG). results showed that contains metal oxides carbonates active sites. In addition, influence reaction conditions evaluated in ranges temperature (60-120 °C), time (0.5-2.5 h), MeOH : oil molar ratio (12 1-28 1) concentration (2-10% weight). maximum ester content (97.6%) achieved 120 °C, 2 h, 20 1 8% catalyst. After partial deactivation solid it regenerated KOH, yielding biodiesels over 75% three consecutive cycles, demonstrating its efficiency potential continuous use.
