There is widespread use of diesel and fossil fuels worldwide. In India, the increasing population and growing dependence on fossil fuels have led to a rise in their consumption, resulting in global warming and environmental pollution. Therefore, there is a need for an alternative solution. Biodiesel presents a promising substitute, as it helps reduce environmental contaminants. It is derived from edible and non-edible oils, as well as their blends. The extracted raw oil undergoes processing through transesterification, a process influenced by various parameters such as the type of catalyst used, the molar ratio of alcohol to oil, the type of alcohol, reaction temperature, and duration. This paper aims to review recent advancements and studies on biodiesel production in recent years, focusing on the use of various edible and non-edible oils to investigate emission, combustion, and engine parameters. The study highlights the advantages of biodiesel in reducing emissions and pollution, while addressing the potential of non-edible oils to avoid food-versus-fuel conflicts and reduce costs. The review also examines the fatty acid content, physical properties, and production yields of different oils, providing a comprehensive analysis of their suitability for biodiesel production.
