Abstract
Growing concerns over environmental impact and limited fossil fuel reserves have led to the urgent need for sustainable and renewable energy alternatives, such as biodiesel, to decrease pollution and ensure long-term energy security. This study focused on utilizing chicken waste oil, a cost-effective by-product of the food industry with high free fatty acid (FFA) content (> 25%), to produce biodiesel that aids waste management. A two-step process involving acid esterification followed by base transesterification was employed. Response surface methodology (RSM) was applied to optimize key process parameters with the aim of improving efficiency and reducing reactant usage. The esterification process reduced the acid value to 1.32 mg KOH g−1, making it optimum for the transesterification process. A maximum biodiesel yield of 98.9% was achieved with reduced reaction time and lower reactant consumption compared to conventional processes, enhancing the process's environmental sustainability and cost-effectiveness. The produced biodiesel exhibited favorable fuel properties, including density (at 20°C), viscosity, and calorific value, satisfying ASTM standards. Chicken waste oil, despite its high FFA content, demonstrates strong potential as a biodiesel feedstock, contributing to reduced CO2 emissions and supporting climate change mitigation.
期刊介绍:
The Journal of the American Oil Chemists’ Society (JAOCS) is an international peer-reviewed journal that publishes significant original scientific research and technological advances on fats, oils, oilseed proteins, and related materials through original research articles, invited reviews, short communications, and letters to the editor. We seek to publish reports that will significantly advance scientific understanding through hypothesis driven research, innovations, and important new information pertaining to analysis, properties, processing, products, and applications of these food and industrial resources. Breakthroughs in food science and technology, biotechnology (including genomics, biomechanisms, biocatalysis and bioprocessing), and industrial products and applications are particularly appropriate.
JAOCS also considers reports on the lipid composition of new, unique, and traditional sources of lipids that definitively address a research hypothesis and advances scientific understanding. However, the genus and species of the source must be verified by appropriate means of classification. In addition, the GPS location of the harvested materials and seed or vegetative samples should be deposited in an accredited germplasm repository. Compositional data suitable for Original Research Articles must embody replicated estimate of tissue constituents, such as oil, protein, carbohydrate, fatty acid, phospholipid, tocopherol, sterol, and carotenoid compositions. Other components unique to the specific plant or animal source may be reported. Furthermore, lipid composition papers should incorporate elements of yeartoyear, environmental, and/ or cultivar variations through use of appropriate statistical analyses.
