The poultry meat industry generates not only large number of products but also large volumes of by-products, such as feather, blood, bones, meat scraps, skin, fatty tissues, feet, skulls and viscera. The poultry industry produces approximately 60 million tons of by-products annually. A significant
component is feather, which is a protein containing 80-90% of keratin. At every chicken slaughter processing, feather waste will be produced at about 5-7% of its total body weight. According to the periodic report published by the US Department of Agriculture in the April 2021, over 13.5 billion ton of chickens were slaughtered in the USA, which annually results in about 270 million kilos of problematic feather waste, and to compare, worldwide, it is around 9 million tons of poultry feather annually. Thus, regarding circular economy the use of waste feather would be beneficial from both the economic and environmental points of view.
