Abstract: Feather keratin (FK) is the waste of poultry industry and will cause environmental problems if it is disposed directly. Recently，the exploitation and utilization of FK has aroused wide interest. The progress of the methods of the extracting soluble feather keratin and the utilization of FK are summarized. FK is mainly used in animal feed，edible packaging materials and composite materials. It can also be used in the modification of polymers，such as polyacrylic acid to increase biodegradability. Utilization of FK as non-feed material，such as FK composite materials and FK modified materials is the future direction of research.
