Description
Summary:Biodiesel （fatty acid methyl ester） has been identified as a non-toxic biodegradable alternative fuel that is obtained from renewable sources. Over the last decade, there has been increasing interest in producing biodiesel from conventional sources such as soybean, canola, sunflower, and coconut oils. Current efforts are directed towards the development of new non-edible resources. Among these Jatropha Curcas comes at the forefront. In Egypt, Jatropha Curcas has grown successfully using primary treated wastewater. Also, extensive R＆D efforts identified the optimum conditions for the various processing stages namely crushing, extraction, transesterification and purification. Based on the research findings, the techno-economic appraisal of biodiesel production from Jatropha Curcas is conducted. Two nominal capacities namely 8,000 and 50,000 metric tons/yr have been proposed. Several scenarios have been formulated to take into consideration varying productivity （3.4 to 5.8 ton fruits per 4,000 m^2 （acre）） and va
