A Review on Sustainable Approach for Production of Biodiesel from Waste Cooking Oil: A Case Study of Brunei Darussalam

Biofuels like biodiesel and bioethanol are the latest technologies to meet rising energy demand replace depleting petroleum supplies. Biodiesel, which is made from vegetable oils, can be used diesel fuel. Vegetable oils a sustainable resource with similar content In proposed process, main product reaction biodiesel, whereas by-products consist of glycerol fertilizer. Biodiesel mainly in automotive engines for various reasons, such as having greater oxygen content, higher cetane number, viscosity, lower aromatic very little sulfur. These properties essential engine performance, combustion, emissions. This review provides comprehensive analysis recent literature on production methods waste cooking oil, where grouped systematically assessed. A decision table process selection provided screen most suitable technology oil. The application potential products also discussed. Finally, case study supplying B5 fuel Brunei Darussalam provided.
