This review explores the environmental and economic impacts of textile waste and discusses the potential for transforming it into eco-friendly materials. Textile waste, generated from the production and disposal of clothing, poses significant challenges to the environment and public health. The review highlights the principles of a circular economy, which aims to reduce waste and promote the reuse of materials. It discusses the recovery and repurposing of textile waste into various industries, such as construction, non-woven production, furniture, carpet, agriculture, and paper. The materials, including cotton, wool, polyester, nylon, and kevlar, offer excellent mechanical, thermal, and acoustic properties, making them suitable for applications ranging from civil construction to insulation and structural reinforcement. The review also examines the challenges and opportunities in recycling textile waste, including the use of mechanical, chemical, and biochemical methods. It emphasizes the importance of life cycle assessment (LCA) in evaluating the environmental impact of textile waste and the need for a transition to a circular economy. The article provides examples of non-woven structures and composites produced from textile waste, highlighting their good thermal and acoustic properties. These materials are being used in various industries to reduce energy consumption and minimize environmental impact. The review concludes by discussing the future prospects of textile waste valorization and the need for increased research and implementation of eco-friendly products.This review explores the environmental and economic impacts of textile waste and discusses the potential for transforming it into eco-friendly materials.
