ABSTRACT
Biodiesel, a renewable and environmentally friendly alternative to conventional diesel fuel, has garnered significant attention due to its potential to address pressing energy and environmental challenges. Biodiesel is a biofuel derived from organic materials, typically vegetable oils, animal fats, or recycled cooking oils, through a process known as transesterification. During this process, these feedstocks are chemically converted into biodiesel and glycerol using alcohol and a catalyst. The resulting biodiesel can be used as a drop-in replacement for conventional diesel fuel, either in pure form (B100) or blended with petroleum diesel (e.g., B5, B20). Biodiesel is also known for its compatibility with existing diesel engines and infrastructure, which facilitates its adoption without significant modifications. However, challenges such as feedstock competition with food crops, energy balance concerns, and land-use change associated with biodiesel feedstock cultivation must be considered. Additionally, ongoing research focuses on improving the production process, exploring alternative feedstocks, and optimizing engine performance. Biodiesel represents a promising solution to reduce the environmental impact of the transportation sector and enhance energy security. Its advantages in emissions reduction, compatibility, and renewability make it a crucial player in the transition to cleaner and more sustainable energy sources. Addressing challenges while continuing to advance the state of the art in biodiesel production and application is essential for its successful integration into our energy landscape.
