As textile production continues to grow worldwide, managing the mounting waste generated by this industry is becoming an urgent environmental concern. Globally, over 92 million tons of are produced annually, much which incinerated or disposed in landfills, contributing greenhouse gas emissions, soil and water contamination, ecosystem harm. This review explores how chemical biotechnological methods, such as acid hydrolysis (achieving up 70% glucose recovery) enzymatic recycling (reducing energy consumption approximately 20% compared conventional methods), can transform into valuable resources, fostering a shift toward circular economy that minimizes reliance on virgin materials. However, diverse nature waste─particularly mixed fibers materials treated with various finishes additives─adds complexity processes, often necessitating specific pretreatment steps ensure both efficiency economic viability. Scalable solutions advanced solvent recovery systems, optimized techniques, fluidized-bed pyrolysis (which increase bio-oil yields 25% fixed-bed reactors) play crucial roles making more sustainable adaptable at industrial scale. By addressing these technical financial challenges, improve sustainability practices, reducing resilience. also suggests several future directions enhance scalability compatibility goals, highlighting potential for technologies create secondary support greener practices management. Through continued innovation commitment better balance resource feasibility, unlocking substantial opportunities mitigate impact resource-efficient, future.

Wool textiles with multifunctional properties such as self-cleaning, antibacterial, electrical conductivity, UV blocking etc. have recently attracted interest. Among the materials employed towards their development, carbon nanotubes (CNTs) been widely investigated due to unique chemical, mechanical and properties, exhibiting also notable UV-blocking properties. However, limited dispersibility in solvents, particularly water, has hindered extensive industrial application diminished significant potential. In this work, two guanidinylated derivatives of hyperbranched polyethyleneimine (GPEI5k PEI 25K) functionalized oxCNTs (oxCNTs@GPEI5K oxCNTs@GPEI5K), exceptional aqueous compatibility colloidal stability, developed our recent publication, were evaluated antibacterial activity on Gram (-) Escherichia coli (+) Staphylococcus aureus bacteria cytotoxicity against mammalian cells, most promising, i.e., oxCNTs@GPEI5K, was subsequently used finishing agent wool fabric. The resulting for color, wash fastness, performance. GPEI-functionalized derivative, exhibited uniform distribution good adhesion onto fabrics yielding sustained even after multiple washing cycles. Additionally, modified improved ultraviolet protection, highlighting potential applications UV-shielding textiles.

Over the decades, interest of textile functionalization using microbial bioactives molecules has increased due to demand for innovative and sustainable materials. Bioactive pigments (biopigments) may attribute several functional properties fibers. These include antimicrobial activity, UV protection anti-odor. This systematic review enumerates objective, evidence, perspectives regarding use biopigments in documents published between 2015 2025. Three large scientific databases were used, 137 recovered, which 6 matched inclusion criteria. There was little material found, but an emerging literature exists, possibly encouraged by demands post-covid-19 pandemic years. The studies showed how have a positive impact on textiles, particularly natural fibers, through advanced dyeing active ingredient incorporation technologies. most assessed biopigment prodigiosin, given its stability, bioactive properties, vibrant solid colors obtained. Few microorganisms been studied, many challenges need be overcome commercially competitive.
