Biodiesel production from animal and poultry wastes

One of the fundamental problems in developed countries has been a growing need to develop new sources of energy، especially in the transportation sector. This problem is not unique to oil importing countries and oil-producing countries are faced with the problem. Biodiesel is a biofuel that produced from renewable materials such as animal fats and vegetable oil and it can be used in the transport section. Using inexpensive oil such as waste animal feed can produce biodiesel economically justify it. In this study، the production of biodiesel from animal and poultry slaughterhouse waste and optimization of chemical and physical parameters affecting the production of biodiesel was investigated. In this work، transesterification method was used to produce biodiesel. The effects of temperature، molar ratio of alcohol to oil and catalyst were studied and optimum conditions were obtained. In the case of animal waste oil، molar ratio 6:1، 1. 25% of catalyst and Temp = 60 ° C، eventually yield was 93%. In the case of Poultry waste، molar ratio 6:1، 1. 25% of catalyst and Temp = 50 ° C، eventually yield was 85%.
