Abstract
SUMMARY Feathers are among the main by-products of the poultry meat industry and are a serious environmental and health liability, with millions of tons being burned or buried annually. However, given their protein nature, they can be used as an energy matrix based on methane-rich biogas, the so-called biomethane. In theory, energy conversion is very cost-effective and would be employable to generate heat or electricity for the producer or the industry. This review presents biotechnological aspects to increase the production of methane-rich biogas (MRB). Topics such as feather quality, keratin hydrolysis (by keratinolytic microorganisms, by alkali and by reducing agents), keratin extraction by rapid vapour explosion, methane production, inoculants for anaerobic digestion and ammonia stripping are addressed.
期刊介绍:
World''s Poultry Science Journal is the official publication of the World’s Poultry Science Association. The journal provides authoritative reviews in poultry science and an international forum for the exchange and dissemination of information including research, education and industry organisation. Each issue includes poultry industry-related news, regional reports on global developments in poultry, reports from specialist scientific working groups, book reviews, association news and a calendar of forthcoming events. Coverage includes breeding, nutrition, welfare, husbandry, production systems, processing, product development, physiology, egg and meat quality, industry structure, economics and education. The journal is of interest to academics, researchers, students, extension workers and commercial poultry producers.
