ABSTRACT
This manuscript presents a comparative study of biodiesel production from various non-edible oils available up to 2018. Biodiesel, a renewable and biodegradable fuel, can be synthesized via transesterification of triglycerides from non-edible feedstocks such as Jatropha curcas, Pongamia pinnata (karanja), and Madhuca indica (mahua) oils. The study reviews literature from 2000 to 2018, outlines experimental design, presents statistical analysis of yield and quality parameters, and identifies research gaps. Results indicate that feedstock properties such as free fatty acid content, viscosity, and fatty acid profile significantly influence biodiesel yield and quality. Karanja oil exhibited the highest average yield (88.3 ± 2.1 %) under optimized conditions, while mahua and Jatropha yields were 85.7 ± 2.5 % and 82.9 ± 3.0 %, respectively. Research gaps include process intensification, catalyst recovery, and techno-economic analyses. Conclusions emphasize the need for scalable, cost-effective processes aligned with 2018 technologies.
