Abstract The utilization of green fuel from inedible biomaterials promotes global health and poverty reduction, as non‐green fuels are costly, negatively impact global health, exacerbate poverty, and their sources are depleting. Hence, the utilization of a novel Acidified Calcined Jatropha Seed Inner Coat Catalyst and Rubber Seed Green Oil. In this work, the Jatropha seed inner coat powder was calcined at 630°C in a furnace as indicated in the thermogravimetric analyzer graph, and then acidified with 0.5 M H 2 SO 4 . Box–Behnken Design (BBD) and Python were utilized to validate and predict the best yield during the transesterification approach. The outcome revealed that Python‐predicted data and plots outperformed BBD, with the input data consisting of a 10/1 MEOH/green‐oil ratio, 70 min, 67°C, and 3.5 wt% green catalyst, generating an endpoint of 96.94 wt% for Python and 96.69 wt% for BBD. Additionally, the Python‐predicted yield was as well higher than the BBD experimental response of 96.72 wt% at 10 MEOH/green‐oil ratio, 65 min, 65°C, 3.5 wt% green catalyst. These results, in addition to the high heating value (HHV), Cetane content, Acid content, Flash and Fire points, were superior to some existing values and it's still within accepted regulations by ASTM (American Society for Testing and Materials) D6751. The Fourier Transform Infrared Spectroscopy test indicated that the strings depicted sounds of the hydroxyl, alkanes, alkynes, alkenes, an ether or a tertiary alcohol, and aromatic class.
