• Raw sheep wool contains various impurities such as wax, suint, dirt, and microorganisms. Water-based cleaning process of sheep wool requires toxic volatile organic compounds that generate a significant portion of toxic effluents. Supercritical CO2 (scCO2) is a waterless technology that has been utilized for sterilization, extraction, cleaning, and drying in various manufacturing sectors. The application of the scCO2 technology in sheep wool processing is cleaner, as it avoids the generation of toxic effluents. scCO2 is a promising technology that can be simultaneously utilized in sheep wool processing for sterilization, extraction of lanolin, and cleaning and drying. Therefore, the present study was conducted to evaluate the potential and limitations of the use of the scCO2 technology for sheep wool processing. Moreover, the properties of sheep wool, the impurities associated with sheep wool fiber, and treatment technology are discussed. •Waterless processing of sheep wool using supercritical CO2.•Removal of impurities from sheep wool fiber for manufacturing textile products.•Water-based sheep wool cleaning processes generate toxic effluents.•scCO2 technology is a promising green method for sheep wool fiber processing.•Clean sheep wool production with supercritical CO2 technology.
