An extensive examination of the potential of waste cooking oil biodiesel in Bangladesh

Waste cooking oil (WCO) has gained attention as a valuable resource for biodiesel production due to its availability and potential for waste management. This study examines the viability of WCO as a biodiesel feedstock in Bangladesh, addressing the increasing demand for sustainable energy alternatives. This paper explores multiple facets of WCO biodiesel, encompassing feedstock types, pretreatment techniques, and the production process. The study analyzes the physicochemical properties, emission characteristics, performance, and combustion behavior of biodiesel derived from WCO. The findings indicate that WCO biodiesel presents considerable potential as an economically viable and environmentally sustainable alternative fuel for diesel engines in Bangladesh. Challenges in WCO collection, commercialization, and public awareness must be addressed to realize its full potential. The paper concludes by proposing avenues for further research in Bangladesh, emphasizing the enhancement of collection systems, the refinement of policy frameworks, and the optimization of conversion technologies to facilitate the broader adoption of WCO biodiesel.
