This review explores the environmental impact of textile waste and its potential valorization into eco-friendly materials through non-woven structures and composites. Textile waste, generated from millions of tons of clothing and footwear annually, poses significant environmental and health risks. The textile industry is the second most polluting and waste-generating sector, contributing to 10% of atmospheric carbon emissions and 20% of global wastewater. Textile waste is often incinerated or landfilled, leading to pollution in air, water, and soil. Circular economy principles aim to reduce waste by reusing and recycling materials, promoting sustainable practices. Textile waste can be repurposed into new products, such as non-woven structures and composites, which have applications in construction, agriculture, and automotive industries. Non-woven structures, made from textile waste, offer thermal and acoustic insulation properties, reducing energy consumption and noise pollution. Composites, produced from textile waste, can be used in civil construction and other industries, providing sustainable alternatives to traditional materials. The review highlights various methods for textile waste valorization, including mechanical recycling, chemical recycling, and biodegradation. Non-woven production involves processes like needle-punching, which can create materials with good thermal and acoustic properties. Composite production uses techniques such as compression molding, vacuum infusion, and thermoforming to transform textile waste into durable materials. The study emphasizes the importance of circular economy principles in reducing environmental impact and promoting sustainable practices. It also discusses the challenges in textile waste management, including low recycling rates, technical barriers, and public awareness. The review concludes that further research and investment are needed to enhance the recovery and utilization of textile waste, leading to the development of eco-friendly products and a more sustainable future.This review explores the environmental impact of textile waste and its potential valorization into eco-friendly materials through non-woven structures and composites.
