“…3 Thus keratin has been tried as a regenerative medicine carrier, 4 a protein fibre, 5 and a finishing agent for textile modification. 6,7 In all of these applications, the molecular weight-dependent mechanical properties of regenerated keratin are necessary. In particular, it is used as a raw material for edible digestive protein membranes, dialysis membranes, semipermeable membranes, 8 and regenerated wool fiber, which has been reported to have the highest molecular weight of 66.4 kDa.…”

A large number of wool fiber by-products, short and coarse wool fibers are difficult to spin and are disposed of by the wool industry, creating a burden on the environment. In this study, L-cysteine hydrochloride and sodium sulfite were used as reducing agents to extract keratin from natural wool in an ethanol-water mixed system. The molecular weight of the extracted keratin is up to 130 kDa with a high yield of 67%. It has been proven that the reducing agent destroyed partial disulfide bonds, ethanol destroyed partial hydrogen bonds and hydrophobic interactions, and the α-helix chain was converted into a β-folded chain and random coil after extraction by instrumental analysis using a Fourier transform infrared spectrometer and X-ray diffraction. The recombination of small keratin molecules can be proven by the increase in protein particle size and molecular weight via a particle size analyzer and SDS-PAGE respectively.

With the growth of the world population and the improvement of living standards, the demand for global textiles has been increasing rapidly. Although natural fibers are affected by the development of synthetic fibers, wool still occupies a certain share in the textile industry and is one of the most indispensable materials. However, many postindustrial and post-consumer waste wool textiles will be produced. The conventional treatment method is landfill or incineration, which is not conducive to economic, environmental, and social development. To counter this problem, many measures and methods have been adapted for the reuse of waste resources. This article provides a review on waste wool recycling and summarizes two main directions for reuse. Waste wool can be used for thermal and sound insulation materials, reinforced composite materials, or adsorbent materials to purify contaminated water which rely on fiber properties. Keratin extracted from waste wool can be applied for the production of high-value products such as functional finishing agents, organic fertilizers, regenerated protein films/fibers, or smart wearable electronic devices. Meanwhile, future development trends and the demand of waste wool recycling are also discussed. Continuous research and exploration are still needed for effective management of waste wool resources and to turn them into useful and valuable materials or products.
