“…Actually, the high level of C/N in mixture C (59.29) at the beginning of composting, which is high compared with mixtures A and B, could be assigned to the poor humification of organic matter and/or low distribution of microbial activity inside of the silos (Biyada et al, 2020a). This is confirmed by microorganism diversity in this study, which is lower for mixture C than that present in mixtures A and B.…”

“…The details of composting methods were described previously (Biyada et al, 2020a). Mixtures were set up for composting with shredded wastes (between 20 and 30 cm) labeled "Mix A, B, and C." Different combinations used are summarized in Table 1, whereas the composition of feedstock used is summarized in Table 2 (Biyada et al, 2020b).…”

“…Textile waste is considered a serious environmental and health problem worldwide due to its high concentration of chemical products including heavy metals (Talouizte, 2014;Talouizte et al, 2017;Biyada et al, 2019). Otherwise, these wastes are a treasure trove of organic matter, which can be converted into a nutrient-rich organic fertilizer and consequently contribute to the rehabilitation of soils by its soil-improving qualities (Biyada et al, 2020a(Biyada et al, , 2021. To recover these wastes and understate or even eliminate their harmful effect on the environment and public health, various strategies have been proposed and developed to transform them into usable resources (Neher et al, 2013).…”

In this study, the effect of initial feedstock concentration on the microbial community structure and dynamics during textile waste composting processes was investigated using the next-generation sequencing approach. For this, three mixtures were prepared with different textile waste concentrations mixed with green waste and paper and cardboard waste for composting, to choose the proportion that will provide a mature final compost. A comprehensive characterization of the microbial communities associated with different textile waste concentrations during composting was achieved. It was noted that by increasing the concentration of textile waste, microbial communities (bacterial and fungal) change. Genera and species belonging to Actinobacteria, Firmicutes, Chloroflexia, Rozellomycota, Mortierellomycota, Aphelidiomycota, Ascomycota, and Mucoromycota were the most abundant in the mixtures containing either 40 or 60% of textile waste, whereas some of the species were absent at 80% of textile waste in the mix; this difference was also reflected by their enzymatic activities. Generally, these phyla are associated with composting, and they play a major role in recalcitrant molecular decaying. Ultimately, it can be concluded that the shift most likely occurred in microbial communities during composting probably owing to the interaction between changes in the nutrient concentration and microbial communities. This investigation proves that the concentration of textile waste significantly affects the microbial communities and demonstrates that a high concentration of textile waste is not suitable to grant a good maturity of compost.

“…In Morocco, the textile industries generate around 4 tons of solid waste annually. This waste is disposed of into the environment without any form of treatment, and thus represents a significant threat to the functioning of many ecosystems 5 . This waste is a fountain of organic matter, which could be recovered biologically through composting into bio-fertilizer, thus providing the nutrients necessary for plant growth.…”

Composting is a promising source of mesophilic and thermophilic microorganisms directly involved in the decay of organic matter. However, there is a paucity of information related to bacterial and fungal diversity in compost and their enzymatic activities during the composting process. In this work, bacterial and fungal diversity during the mesophilic and thermophilic phases of textile waste composting was investigated as a way to explain the physical–chemical results obtained during the composting process. This was accomplished using a next-generation sequencing approach that targets either the 16S rRNA or ITS genomic regions of bacteria and fungi, respectively. It was observed that Proteobacteria, Bacteroidetes, and Actinobacteria were the dominant bacterial phyla present at the mesophilic phase but not at the thermophilic one. Composting textile waste exhibits a sustained thermophilic profile (above 55 °C) that usually precludes fungal activity. Nonetheless, the presence of fungi at the thermophilic phase was observed. Rozellomycota, Basidiomycota, and Ascomycota were the most dominant phyla during both composting phases. Such thermophilic fungi with great ability to decay organic matter could be isolated as pure cultures and used for the bioaugmentation of textile waste composting to achieve an advanced maturity level of textile waste compost.
