A green process for producing biodiesel from chicken skin and its feather as a cost-effective feedstock

Abstract

Biodiesel was produced from renewable BioSource (waste poultry feedstock). Oil was extracted from waste chicken poultry feedstock collected from slaughter houses of Muscat Area, Sultanate of Oman. Alkaline trans-esterification reaction was conducted using the extracted oil and methanol in the presence of a liquid phase catalyst to produce the biodiesel. Qualitative analysis of extracted oil and produced biodiesel was carried out. The effect of reaction time, reaction temperature, methanol/oil molar ratio, catalyst amount and stirring speed was evaluated. The maximum yield of biodiesel (89%) was obtained at optimum conditions of 6:1 molar ratio of methanol/oil, 90 min reaction time, 5 g of catalyst, 60°C reaction temperature and 400 RPM stirring speed. The quality of produced biodiesel (B100 and B20) was compared with ASTM D6751 standards.
