Protein and Amino Acid Recovery from Organic Wastes by Using Thermal Hydrolysis and Membrane

摘要

A method for recovering proteins and amino acids from organic wastes is disclosed. After the organic waste is thermally hydrolyzed and dehydrated to remove solids, the solids are removed, and the protein and amino acid-containing liquid reaction products are filtered to remove residual impurities and concentrate to recover proteins and amino acids. By using physical methods such as thermal hydrolysis and membranes without the use of chemicals, safe high purity proteins and amino acids can be extracted from organic wastes such as livestock manure.
