Fossil fuels are non-renewable sources of energy which generate pollutants and are linked to global warming and climatic change. In order to overcome these problems, there is a need for an alternative for fossil fuels. The most common renewable fuel is biodiesel which is produced from vegetable oils, animal fat wastes and poultry. The aim of the present work was to study the transesterification of liquid fat resulted from chicken roasting. This fat was esterified with methanol and NaOH as a basic catalyst. Product yield of chicken fatty acid methyl Ester (CFME) was 79.1 % for liquid fat resulted from roasting. All quality control parameters for biodiesel produced (B100) were generally in agreement with ASTM standards. It can be concluded that chicken fat resulted from roasting is suitable for low cost feed stocks for biodiesel production.
