If yellow grease is being used as feedstock for biodiesel production, how many pounds of feedstock are needed to make one gallon of biodiesel? You can assume that yellow grease is composed of 15% FFA, 5% water, 0.5% insoluble solids (all in w/w) and the rest is triglycerides. Use oleic acid for FA and oleic acid methyl ester for biodiesel
