| Summary: | The following report represents the efforts of the Centre for Aquaculture and Seafood Development (CASD) research team in characterizing marine oils to identify its potential use as biodiesel feedstock and establish technology in the area of energy and waste management, enhance the competitiveness of Newfoundland and Labrador’s biofuels and help Canada to meet its commitment to GHG emission building the renewable fuels. To date, biodiesel is not readily available in Newfoundland and Labrador, and there are no biodiesel producers operating within the province. The scope of this project is the development of an economically viable and environmentally sustainable biodiesel production system for rural communities in Newfoundland and Labrador and to help marine processing plants cut down their operating cost, by diminishing the problem of fish waste disposal, and by providing alternative fuel for the operation of feed barges, marine vessels and generators located at their remote locations. Crude cod (Gadus morhua) liver, Pacific salmon (Oncorhynchus) and Atlantic salmon (Salmo salar) oil were characterized to identify their suitability for biodiesel production. Since the feedstock oils used for biodiesel production are of diverse origin and quality, initial evaluation of the physical and chemical composition of the feed stock oil is very essential prior to biodiesel production. Investigation of physical properties (smell, color, physical state, moisture and specific gravity), chemical properties (pH, ash content, acid value, iodine value, saponification value, p-anisidine value, peroxide value, TOTOX value, free fatty acid, flash point, kinematic viscosity and refractive index) and lipid and fatty acids classification were performed on all marine oils. The characterized marine oils were pale yellow to orange in color and were stable at liquid state at room temperature. The pH (6.5-6.8) values of all oils were neutral. The specific gravity (0.921-0.924 g/cm3), water content (179-325 ppm), ash content ... |
