The main objective of this book is to recycle human hair waste produced from salons and chicken feather waste produced during the processing of chicken for food into a useful composite. Chicken feather fiber (CFF) and human hair fiber (HHF)are clear livestock wastes that are currently used in various applications like textiles, crafts, decorations, and even bio composites. The reviews of the many literature sources have been compiled here to increase researchers' awareness of the use of CFF and HFF as reinforcing materials in the creation of diverse composites. In the past, the majority of researchers have placed emphasis on the different types of natural plant fibers. Thus, the reviews are organized for change and sustainable development. Hair is composed of 95% keratin, a fibrous and helical protein, which is part of the composition of the skin and of all the phanera. Chicken feathers are made up of quills and fiber. Both of them consist of hydrophobic keratin, a protein that has high strength, low density, and high biodegradability. We are presenting an idea to make polymer matrix composites from these waste chicken feathers.
