Omic advantages of textile recycling and supplied probably the most systematic critique we found on textile recycling. The overview explored the socio-economic positive aspects of textile recycling and pinpointed barriers to the optimization of textile recycling without having specifying if they had been arranged by importance: (1) financial viability, (2) composition of textile merchandise, (three) non availability of recyclable textile supplies, (four) technological limitations, (5) lack of information and limited public participation, and (6) poor coordination, and weak policies and requirements. In comparison, Holes and Holes investigated efficient policies and incentives worldwide for elevated recycling from other sectors to reveal possibilities for extrapolation towards the textile sector. A short overview over the challenges identified is exposed, respectively: (1) the lack of incentives to motivate customers for recycling; (2) informational and educational programs; (three) collection options of textile waste; (4) absence of policies and regulations regarding textile recycling; (five) selection of textile fibers and chemical substances. Conversely, various reports and white papers on textile recycling [9,17,62] have already been published more than the years, supplying flourishing grey literature on the topic. Especially, the Ellen MacArthur Foundation identified four priorities to enhance textile-to-textile recycling [9]: align clothing design and recycling processes, pursue technological innovation to enhance the economics and Arterolane In stock quality of recycling, stimulate demand for recycled materials, and implement clothing collection at scale. A number of other publications have addressed the challenges of textile recycling. For instance, Elander and Ljungkvist investigated through in-depth interviews with style companies, textile sorters, and recyclers 43 essential elements for growing textile-to-textile recycling [63]. Roos et al. [17] compiled a state-of-the-art on existing technologies although outlining the essential factors for the future of textile recycling.Sustainability 2021, 13,10 ofBased around the reported challenges in the academic literature, a thorough mapping was framed, as shown in Table 1. The mapping essentially emphasizes the academic literature to outline the studies conducted so far even though highlighting the fragmented state with the investigation. This literature assessment supported the implementation of our Delphi-R nier study, plus the challenges are further elaborated collectively using the findings within the dedicated section. 3. Research Approach Thinking about the goal on the analysis, the mixture with the Delphi process and also the Regnier’s Abacus method emerged because the most relevant strategy. By enabling consensus and dissensus on a topic to arise, this research method aids to advance empirical information on textile recycling when outlining the priority challenges to address in the sector with regards to previous investigation [14,39,46]. Additionally, it appeared because the most viable method to evaluate a series of wide-range assumptions on the LX2761 Biological Activity subject with a wide panel of experts and generate valid leads to a timely manner [43]. The appropriateness in the method was also evaluated within the surrounding business context [43]. As a spotlighted concern within the sector, anonymity was critical to ensure participation and minimize the threat of bias. Moreover, confronting opinions on the subject was decisive to attain the study objectives, but direct communication amongst the distinctive professionals could have blocked open reflecti.
