“…Textile recycling reuses or reprocesses used clothing, fibrous material, and clothing waste recovered from manufacturing processes [62]. It is a very important process for CE in the fashion industry and has been addressed by several studies [64][65][66][67][68][69][70].…”

Circular economy (CE) principles have gained prominence in the fashion industry since it is a highly polluting industry and requires sustainable changes. Even though there are several CE initiatives already in place within the fashion production chain, changes towards CE are still slow. This study seeks to identify the drivers, barriers, and practices that influence implementing circular economy concepts in the fashion industry production chain using a systematic literature review. The results show that some more barriers and criteria keep consumers away from circular fashion concepts than drivers. These barriers include fast fashion consumer culture, even though more consumers are environmentally conscious. This is because awareness has not reached large-scale populations, despite the world being more aware of social and environmental issues. Consumers still do not see ethical and ecological problems associated with the fashion industry and continue to be targeted for large fast fashion retailers that sell a misguided version of consumerism. This study contributes to both academia and new fashion business models that seek to become more sustainable since it presents opportunities for investments and the obstacles that must be overcome for reaching CE within this sector.

The fashion industry contributes to a significant environmental issue due to the increasing production and needs of the industry. The proactive efforts toward developing a more sustainable process via textile recycling has become the preferable solution. This urgent and important need to develop cheap and efficient recycling methods for textile waste has led to the research community’s development of various recycling methods. The textile waste recycling process can be categorized into chemical and mechanical recycling methods. This paper provides an overview of the state of the art regarding different types of textile recycling technologies along with their current challenges and limitations. The critical parameters determining recycling performance are summarized and discussed and focus on the current challenges in mechanical and chemical recycling (pyrolysis, enzymatic hydrolysis, hydrothermal, ammonolysis, and glycolysis). Textile waste has been demonstrated to be re-spun into yarn (re-woven or knitted) by spinning carded yarn and mixed shoddy through mechanical recycling. On the other hand, it is difficult to recycle some textiles by means of enzymatic hydrolysis; high product yield has been shown under mild temperatures. Furthermore, the emergence of existing technology such as the internet of things (IoT) being implemented to enable efficient textile waste sorting and identification is also discussed. Moreover, we provide an outlook as to upcoming technological developments that will contribute to facilitating the circular economy, allowing for a more sustainable textile recycling process.

“…Textile fibers are primarily made from petrochemical materials, such as polyethylene terephthalate (PET) [4], nylon [5], and polypropylene [6]. Unused textile fibers are typically incinerated, which contributes to environmental pollution [7,8]. Environmental considerations are of increasing importance, and the development of environmentally friendly materials guarantees sustainable growth of the textile industry.…”
