Abstract

Textile waste is becoming among the most polluting waste in the world, discarded mostly in landfills. Valorizing textile waste via anaerobic digestion (AD) helps conserve resources, reduce environmental impact, and foster a circular economy. Although several reviews have discussed textile waste AD, there is a lack of detailed understanding of the challenges encountered during textile waste AD. Therefore, the goal of this review is to focus on challenges encountered and possible solutions for those challenges for biogas and fertilizer conversion via AD. Potential strategies include chemical, biological, and thermal pretreatments that significantly increase the digestion process. Co-digestion of natural textile waste, cotton, and wool with carbon and nitrogen-rich substrates improves AD efficiency by twofold. Moreover, separating polyester from polycotton and textile dye removal via solvent and advanced oxidation processes significantly increases methane yield compared with untreated textile waste. This review can aid in analyzing suitable methods to optimize the biogas production of textile waste via AD.

厌氧消化用于纺织废物处理和增值

纺织废弃物正成为世界上污染最严重的废弃物之一，大部分被丢弃在垃圾填埋场。通过厌氧消化（AD）实现纺织废物的价值化有助于节约资源、减少对环境的影响并促进循环经济的发展。虽然有多篇综述讨论了纺织废物厌氧消化，但对纺织废物厌氧消化过程中遇到的挑战缺乏详细了解。因此，本综述的目标是重点探讨通过厌氧消化（AD）技术进行沼气和肥料转化时遇到的挑战以及应对这些挑战的可能解决方案。潜在的策略包括化学、生物和热预处理，这些方法可显著提高消化过程。天然纺织废料、棉花和羊毛与富含碳和氮的基质共同消化，可将厌氧消化（AD）效率提高两倍。此外，与未经处理的纺织废料相比，通过溶剂和高级氧化工艺将聚酯从聚棉和纺织染料中分离出来，可显著提高甲烷产量。本综述有助于分析通过厌氧消化（AD）优化纺织废物沼气生产的合适方法。
