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 textile waste are produced annually, much of which is incinerated or disposed of in landfills, contributing to greenhouse gas emissions, soil and water contamination, and ecosystem harm. This review explores how chemical and biotechnological methods, such as acid hydrolysis (achieving up to 70% glucose recovery) and enzymatic recycling (reducing energy consumption by approximately 20% compared to conventional methods), can transform textile waste into valuable resources, fostering a shift toward a circular economy that minimizes reliance on virgin materials. However, the diverse nature of textile waste-particularly in mixed fibers and materials treated with various finishes and additives-adds complexity to recycling processes, often necessitating specific pretreatment steps to ensure both efficiency and economic viability. Scalable solutions such as advanced solvent recovery systems, optimized pretreatment techniques, and fluidized-bed pyrolysis (which can increase bio-oil yields by up to 25% compared to fixed-bed reactors) play crucial roles in making textile recycling more sustainable and adaptable at an industrial scale. By addressing these technical and financial challenges, the industry can improve the efficiency and sustainability of textile recycling practices, reducing waste and contributing to environmental resilience. This review also suggests several future directions to enhance scalability and compatibility with environmental goals, highlighting the potential for these technologies to create valuable secondary materials and support greener practices in textile waste management. Through continued innovation and a commitment to sustainable practices, the textile industry can better balance resource recovery with economic feasibility, unlocking substantial opportunities to mitigate environmental impact and support a more resource-efficient, sustainable future.
随着全球纺织品产量持续增长,管理该行业产生的日益增多的废弃物正成为一个紧迫的环境问题。在全球范围内,每年产生超过9200万吨的纺织废弃物,其中大部分被焚烧或填埋处理,这导致了温室气体排放、土壤和水污染以及生态系统损害。本综述探讨了化学和生物技术方法,如酸水解(葡萄糖回收率高达70%)和酶循环利用(与传统方法相比,能源消耗降低约20%),如何将纺织废弃物转化为有价值的资源,推动向循环经济的转变,从而最大限度地减少对原生材料的依赖。然而,纺织废弃物的多样性——特别是混合纤维以及经过各种整理和添加剂处理的材料——给回收过程增加了复杂性,通常需要特定的预处理步骤以确保效率和经济可行性。诸如先进的溶剂回收系统、优化的预处理技术和流化床热解(与固定床反应器相比,生物油产量可提高多达25%)等可扩展解决方案,在使纺织回收在工业规模上更具可持续性和适应性方面发挥着关键作用。通过应对这些技术和资金挑战,该行业可以提高纺织回收实践的效率和可持续性,减少废弃物并增强环境恢复力。本综述还提出了几个未来方向,以提高可扩展性并与环境目标兼容,强调了这些技术创造有价值的二次材料以及支持更环保的纺织废弃物管理实践的潜力。通过持续创新和致力于可持续实践,纺织行业可以更好地在资源回收与经济可行性之间取得平衡,释放大量机会以减轻环境影响并支持更具资源效率、可持续的未来。
