The growing environmental impact of textile waste, fueled by the rapid rise in global fiber production, underscores urgent need for sustainable end-of-life solutions. This review explores cutting-edge pathways waste management, spotlighting innovations that reduce reliance on incineration and landfilling while driving material circularity. It highlights advancements collection, sorting, pretreatment technologies, as well both established emerging recycling methods. Smart collection systems utilizing tags sensors show great promise streamlining logistics automating pick-up routes transactions. For automated technologies like near-infrared hyperspectral imaging lead way accurate scalable separation. Automated disassembly techniques are effective at removing problematic elements, though other pretreatments, such color finish removal, still to be customized specific streams. Mechanical is ideal textiles with strong mechanical properties but has limitations, particularly blended fabrics, cannot repeated endlessly. Polymer recycling-through melting or dissolving polymers-produces higher-quality recycled materials comes high energy solvent demands. Chemical recycling, especially solvolysis pyrolysis, excels breaking down synthetic polymers polyester, potential yield virgin-quality monomers. Meanwhile, biological methods, their infancy, natural fibers cotton wool. When methods not viable, gasification can used convert into synthesis gas. concludes future hinges integrating sorting advancing solvent-based chemical technologies. These innovations, supported eco-design principles, progressive policies, industry collaboration, essential building a resilient, circular economy.

A novel strategy utilizing wool waste to prepare carbonized porous C/N/O co-doped TiO₂ composites for enhancing adsorption and photocatalytic degradation of organic pollutants

Textile Research Journal, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 4, 2025

The extensive production of waste wool in the textile industry poses significant environmental challenges. To address this issue, we present a novel recycling approach that transforms into carbonized, porous, and C/N/O co-doped TiO 2 composite material. This was achieved through simple one-step hydrothermal synthesis followed by calcination either nitrogen or an air atmosphere. innovative method not only repurposes but also creates material with impressive adsorption photocatalytic properties, offering new solution for remediation. process effectively dispersed nanoparticles, increasing number active sites. When calcined atmosphere, graphitization biochar enhanced, doping achieved, oxygen vacancies were created, all which significantly improved performance. resulting exhibited capacity methylene blue dye 13.8 times higher than untreated sample, 9.9 sample air. Furthermore, retained 99% its original after second cycle, indicating strong potential. Photocatalytic performance tests showed marked improvement degradation efficiency blue, Congo red, tetracycline hydrochloride under simulated solar irradiation. primary species involved singlet ( 1 O ) photogenerated holes (h + ), while superoxide radicals ([Formula: see text]) hydroxyl (‧OH) contributed to photodegradation blue. use as catalyst support extends practical applications helps reduce impact organic pollutants.

Chemical Valorization of Textile Waste: Advancing Sustainable Recycling for a Circular Economy

ACS Omega, Journal Year: 2025, Volume and Issue: unknown

Published: March 19, 2025

As textile production continues to grow worldwide, managing the mounting waste generated by this industry is becoming an urgent environmental concern. Globally, over 92 million tons of are produced annually, much which incinerated or disposed in landfills, contributing greenhouse gas emissions, soil and water contamination, ecosystem harm. This review explores how chemical biotechnological methods, such as acid hydrolysis (achieving up 70% glucose recovery) enzymatic recycling (reducing energy consumption approximately 20% compared conventional methods), can transform into valuable resources, fostering a shift toward circular economy that minimizes reliance on virgin materials. However, diverse nature waste─particularly mixed fibers materials treated with various finishes additives─adds complexity processes, often necessitating specific pretreatment steps ensure both efficiency economic viability. Scalable solutions advanced solvent recovery systems, optimized techniques, fluidized-bed pyrolysis (which increase bio-oil yields 25% fixed-bed reactors) play crucial roles making more sustainable adaptable at industrial scale. By addressing these technical financial challenges, improve sustainability practices, reducing resilience. also suggests several future directions enhance scalability compatibility goals, highlighting potential for technologies create secondary support greener practices management. Through continued innovation commitment better balance resource feasibility, unlocking substantial opportunities mitigate impact resource-efficient, future.
