Production and Characterization of Biodiesel from Fatty Residues of Capra hircus

Abstract

Background: Non-vegetarian f ood (meat, chicken and beef) sl aughtering is one of the world’s most rapidl y i ncreasing food industries. The wastes produced in the slaughterhouse are rapidly causing unhygienic conditions and pollution in and around the civil area. In this way, while meeting the food requirement of people, it is also causing a threat to health. Using natural resources is one of the essential innovations in producing energy. Biodiesel is a valuable renewable energy source because it is biodegradable and non-toxic. Methods: This study aims to upgrade the reformation of fat residues of Capra hircus into biodiesel by using 0.96% wt KOH as a catalyst. The waste organs, including stomach, skin and fatty residues, were brought locally in the meat shop. Fat contents were extracted in ethyl alcohol from the waste organs through the Soxhlet apparatus and purified with a rotary evaporator. The crude biodiesel was obtained from animal fat through a trans-esterification reaction. The animal fat and crude biodiesel sample were quantitatively analyzed using FT-IR spectroscopy. Result: In the fat sample range of peak value between 3552.28 to 2974.23 cm-1 is recognized to-C=CH (C is double bond stretching) was represented to monounsaturated fatty acid (MUFA). Furthermore, the crude biodiesel is monitored by the intensity of the C-O ester Peak at 1742.72 cm-1. Finally, we concluded that obtained sample via trans-esterification reaction is biodiesel.
