In recent years, there have been increasing concerns in the disposal of textile waste around the globe. The growth of textile markets not only depends on population growth but also depends on economic and fashion cycles. The fast fashion cycle in the textile industry has led to a high level of consumption and waste generation. This can cause a negative environmental impact since the textile and clothing industry is one of the most polluting industries. Textile manufacturing is a chemical-intensive process and requires a high volume of water throughout its operations. Wastewater and fiber wastes are the major wastes generated during the textile production process. On the other hand, the fiber waste was mainly created from unwanted clothes in the textile supply chain. This fiber waste includes natural fiber, synthetic fiber, and natural/synthetic blends. The natural fiber is mostly comprised of cellulosic material, which can be used as a resource for producing bio-based products. The main challenge for utilization of textile waste is finding the method that is able to recover sugars as monosaccharides. This review provides an overview of valorization of textile waste to value-added products, as well as an overview of different strategies for sugar recovery from cellulosic fiber and their hindrances.
近年来，全球范围内对纺织品废物处理的关注度不断增加。纺织市场的增长不仅取决于人口增长，还取决于经济和时尚周期。纺织行业的快时尚周期导致了高消费和废物产生。由于纺织和服装行业是污染最严重的行业之一，这可能会对环境造成负面影响。纺织品制造是一个化学密集型过程，其运营过程需要大量的水。废水和纤维废物是纺织生产过程中产生的主要废物。另一方面，纤维废物主要来自纺织供应链中不需要的衣服。这种纤维废物包括天然纤维、合成纤维和天然/合成混合物。天然纤维主要由纤维素材料组成，可作为生产生物基产品的资源。利用纺织品废物的主要挑战是找到能够将糖回收为单糖的方法。本综述提供了对纺织品废物增值产品的概述，以及从纤维素纤维中回收糖的不同策略及其障碍的概述。
