Keratin-rich materials to biogas

Keratin rich materials such as hair, horns, nails, feathers, claws and hooves of mammals are produced by poultry industry and slaughterhouse. According to Commission of the European Communities, these wastes can be land filled. However, deposition of these materials can not be a good idea since they can be used in biogas digester to produce methane. Keratin-rich materials are not suitable source for anaerobic digestion because keratin is very resistant. Hence some pre-treatments are necessary before the anaerobic digestion.
