Physical and chemical properties of fish oil biodiesel produced in Brazil

Due to the energy crisis caused by the progressive depletion of fossil fuel sources, the search for alternative fuels from renewable sources is in growing demand. Therefore, the manufacturing of biodiesel from fish waste might help the environment as an alternative for the reduction of residues that are harmful if incorrectly disposed. Biodiesel from residual oil of tilapia waste was manufactured by means of transesterification, basic catalysis and methyl route. This study assessed mandatory parameters regulated by the Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP) for biodiesel commercialization. It also determined values for specific mass, kinematic viscosity, water content, acidity level, flash point, oxidative stability and calorific value of fish oil biodiesel. Biodiesel calorific value analysis reported levels that are similar to those of diesel. Other parameters that characterize fish oil biodiesel physically and chemically according to specifications of ANP resolution No. 7/2008 were evaluated, and indicated that fish oil is a promising alternative for biodiesel manufacturing.
