Biodiesel Fuel Production from Palm, Sunflower Waste Cooking Oil and Fish Byproduct Waste as Renewable Energy and Environmental Recycling Process.

Significant of the Study: Biomass is renewable, organic, plant and animal derived source of biomaterial that can be converted into different forms of biofuel, bioplastic, bio-solvent, and bioenergy using different biotechnological procedures. Biomass derived bio-fuel is biodegradable, nontoxic, sustainable and substitute for fossil fuel as well as capable to reduce greenhouse gas emission. It is renewable and outstanding energy resource for the creation of steam and electricity, transportation fuel, manufacturing industries. Biomass derived from animal and plants like, fruits, vegetable, crops, fish, chicken and other animal byproducts or waste biomass which can be used for bioenergy production like biofuel and nano-catalyst for biofuel. Aim: The purpose of this study was to compare and investigate the suitable biodiesel properties produced from waste fish byproducts, palm and sunflower oil which were more economically viable. Results: There was a total of 7, 5 and 4 types of fatty acid methyl esters presence in the fish, palm and sunflower biodiesel, respectively. The quality of biodiesel such as viscosity, total acid number, fuel consumption and emission rate was evaluated. The kinematic viscosity was maintained ASTM standard in case of all produced biodiesel. However, sunflower biodiesel was slightly viscous compared to palm and fish biodiesel. Metal elements such as phosphorus, magnesium, and calcium were present moderately in all biodiesel but it was limited range in fish oil. In the engine tests, the emissions of unburned hydrocarbons, oxides of nitrogen and carbon monoxide were lower in palm biodiesel than in sunflower and fish biodiesel. Fuel consumption was higher in palm biodiesel. Fish biodiesel had the lowest fuel consumption than that of palm and sunflower biodiesel. Conclusion: It can be concluded that waste palm oil and fish oil can be considered as a great potential source for commercial biodiesel.
