Renewable Dual Fuel Generation through Fermentation and Transesterification of Sugarcane Juice and Waste Cooking Oil

This study presents an integrated approach for producing bioethanol and biodiesel from sugarcane juice and waste vegetable oil, two abundant agro-industrial by-products. Through optimized fermentation and transesterification processes, we achieved high ethanol yields and produced fatty acid ethyl esters meeting ASTM and EN fuel standards. This dual biofuel generation process supports India's national biofuel blending targets, promotes sustainability, and offers implications for global renewable energy strategies. The resulting biodiesel exhibited a cetane number of 53.6 and met ASTM D6751 and EN 14214 standards, confirming fuel-grade quality.
