Cotton Spinning Waste: A Review of Recycling Technology and Circular Economy Application
Abstract
Cotton spinning waste has become a critical issue in the textile industry due to rapid global fashion consumption, high production volumes, and the increasing demand for cotton-based fabrics. Waste is generated at every stage of cotton processing, from spinning, carding, and combing to garment cutting and post-consumer disposal. Managing this waste is essential to protect the environment, reduce the pressure on virgin cotton production, and support long term sustainability. This review paper thoroughly examines cotton spinning waste sources, environmental and economic impacts, and the role of mechanical, chemical, and biological recycling technologies in restoring waste into high value fibers. Modern technological innovations such as automated sorting, solvent dissolution, enzyme assisted hydrolysis, and fiber regeneration systems are identified as major drivers for textile circularity. The review also analyzes Pakistan’s present situation, its waste management challenges, and viable opportunities for improvement. Integrating circular economy models such as extended producer responsibility, recycled content mandates, and industrial collaboration emerges as a practical pathway toward sustainability. Overall, cotton spinning waste is not just a challenge but a valuable resource when supported by the right technologies, policies, and industry practices.
