Production of biodiesel, cellulosic sugars, and peptides from the simultaneous esterification and alcoholysis/hydrolysis of materials with oil-containing substituents including phospholipids and peptidic content

A method for making fatty acid alkyl esters, the method comprising:

• (a) combining an unextracted feedstock with an alcohol, wherein the feedstock comprises phospholipids, at least 10 wt % cellulosic material based on the dry weight of the feedstock, and at least 10 wt % proteins based on the dry weight of the feedstock and the water content of a combination of the feedstock and the alcohol is at least 10 wt % of the dry weight of the feedstock;
• and
• (b) reacting the combination of the feedstock and the alcohol at a temperature in the range of 240° C. to 300° C., and at a pressure in a range of 1000 psig to 2000 psig to generate fatty acid alkyl esters from the phospholipids and cleave the cellulosic material and the proteins.
