The present study focuses on the impact of sheeps’ wool on the environment if it becomes waste. Wool is a keratin-rich by-product that is resistant to degradation, and appropriate management plans for this type of waste should be carefully considered. Some studies consider hydrolyzation of wool, but these processes are implying the use of harsh chemicals for the environment. Therefore, different methods for the valorization of wool waste refer to composting, obtaining fertilizers for using them in agriculture, producing cosmetics, or for thermally-isolating of houses. Special attention is paid to the extraction of keratin from wool, as this is the most valuable by-product resulting from the process of sheep shearing.
