Introduction

The textile industry faces growing scrutiny over its substantial environmental impact, prompting a critical focus on sustainability across its entire value chain. Life Cycle Assessment (LCA) methodologies are instrumental in evaluating this impact, from raw material extraction to disposal, highlighting critical areas like energy use, water pollution, and greenhouse gas emissions. Identifying these hotspots in the supply chain guides improvements for sustainable production and consumption through better material selection, process efficiency, and end-of-life management [1].

Embracing the circular economy is another key strategy, with models such as â??textile symbiosisâ? emerging to integrate principles of design for longevity, resource recovery, and collaborative consumption. These approaches aim to significantly reduce waste and environmental harm within the fashion industry, necessitating systemic changes involving technological innovation, policy support, and consumer engagement for a truly circular ecosystem [2].

Advances are also transforming specific processes, particularly textile dyeing, where innovative and sustainable methods are reducing water consumption, chemical usage, and energy footprints. This includes natural dyes, enzymatic dyeing, supercritical CO2 dyeing, plasma treatment, and digital printing technologies, all pushing for greener industrial production [3].

Material innovation plays a vital role in this transition, exemplified by the potential of advanced cellulosic materials. These bio-based fibers, extracted and modified from various biomass sources, offer enhanced properties, biodegradability, and renewability for diverse textile applications. Addressing challenges in their large-scale production and commercialization is crucial for their wider adoption [4].

Similarly, sustainable textile waste management is essential, involving trends in collection, sorting, reuse, and recycling for both pre-consumer and post-consumer waste. Despite challenges like mixed fiber composition, opportunities exist for valorizing waste through innovative material recovery and circular business models [5].

Green chemistry principles are increasingly applied in textile processing to minimize environmental impact. Techniques like enzyme-assisted processing, supercritical fluid technology, and eco-friendly chemicals reduce water and energy consumption, while preventing hazardous waste. These methods offer viable pathways for a more sustainable textile industry [6].

Furthermore, the development of sustainable natural fiber composites, incorporating materials like flax, hemp, and jute into polymer matrices, creates materials with improved mechanical properties, reduced environmental footprints, and enhanced biodegradability for advanced textile applications. Optimizing fiber-matrix adhesion remains a challenge but promises high-performance, eco-friendly products [7].

Consumer behavior is a significant factor in promoting sustainable fashion, requiring research into the motivations, barriers, and psychological influences affecting purchasing decisions for eco-friendly textiles. Understanding these dynamics is crucial for fostering sustainable consumption patterns and informing future research agendas [8].

Environmental concerns also extend to industrial effluent, where Advanced Oxidation Processes (AOPs) are being developed for textile wastewater treatment. Techniques like Fenton, photo-Fenton, ozonation, and photocatalysis efficiently degrade organic pollutants and dyes, contributing to stringent environmental discharge standards and sustainable water management [9].

Finally, emerging technologies are enhancing supply chain integrity. Blockchain technology offers significant potential to improve transparency, traceability, and accountability in fashion and textile supply chains. By tracking materials from sourcing to delivery, blockchain can combat issues like unethical labor practices and environmental pollution, fostering more trustworthy and sustainable textile ecosystems despite implementation challenges [10].

Description

The textile industry significantly impacts the environment, a concern that necessitates comprehensive assessments like Life Cycle Assessment (LCA). LCA methodologies critically evaluate the entire life cycle of textile materials, from the initial extraction of raw resources through manufacturing processes, consumer use, and ultimate disposal. This analytical approach reveals major environmental burdens, including extensive energy consumption, severe water pollution, and substantial greenhouse gas emissions. By pinpointing these environmental hotspots within the textile supply chain, researchers can identify areas ripe for improvement. Proposed solutions often involve optimizing material selection, enhancing the efficiency of production processes, and implementing advanced strategies for end-of-life management, all contributing to a more sustainable textile economy [1].

To counter the linear "take-make-dispose" model, the concept of a circular economy is gaining traction in sustainable fashion. A "textile symbiosis" model, for instance, proposes that businesses integrate circular principles into their core operations. This means designing products for extended longevity, prioritizing resource recovery from used textiles, and fostering collaborative consumption patterns to minimize overall waste and environmental impact. Realizing a truly circular textile ecosystem, however, requires multifaceted changes. This includes fostering technological innovation for recycling and material recovery, implementing supportive policies, and actively engaging consumers to shift their purchasing and usage habits [2]. Concurrently, significant progress is being made in reducing the environmental footprint of textile dyeing, a traditionally polluting process. Reviews highlight advancements in innovative and sustainable dyeing techniques, such as the use of natural dyes, enzymatic processes, supercritical CO2 dyeing, plasma treatments, and digital printing. These methods are specifically designed to reduce water, chemical, and energy consumption, representing a push towards greener industrial practices, though their widespread adoption still faces technical and economic challenges [3].

Material science is also driving sustainability, particularly through advanced cellulosic materials. These innovations focus on new methods for extracting and modifying cellulose from various biomass sources, resulting in fibers with enhanced properties suitable for diverse textile applications. The environmental advantages of these bio-based materials are considerable, notably their inherent biodegradability and renewability, offering a sustainable alternative to conventional fibers. However, scaling up their production for industrial use and ensuring their commercial viability remain critical challenges to address [4]. Another avenue in material development involves sustainable natural fiber composites. By integrating natural fibers like flax, hemp, and jute into polymer matrices, researchers are creating materials with superior mechanical properties, a reduced environmental footprint, and enhanced biodegradability. These composites hold promise for high-performance, eco-friendly textile products, with ongoing research focusing on optimizing fiber-matrix adhesion to maximize their potential [7].

Effective management of textile waste is paramount for closing the material loop. This involves a comprehensive look at current trends in textile collection, sorting, reuse, and recycling technologies, addressing both waste generated before products reach consumers and discarded post-consumer items. While significant hurdles exist, such as the complexity of mixed fiber compositions and the economic feasibility of certain recycling processes, there are clear opportunities for valorizing textile waste. This is achieved through innovative material recovery techniques and the development of circular business models that transform waste into valuable new resources [5]. Complementing these efforts are green chemistry principles applied across textile processing. These principles guide the development of innovative techniques, including enzyme-assisted processing and supercritical fluid technology, along with the use of eco-friendly chemicals in pre-treatment, dyeing, and finishing stages. The goal is to minimize water and energy consumption, prevent hazardous waste generation, and provide viable pathways for a more environmentally responsible textile industry [6].

Beyond production, understanding consumer behavior towards sustainable fashion is crucial. Reviews in this area synthesize existing knowledge, delving into the motivations, barriers, and psychological factors that influence purchasing decisions for eco-friendly and ethically produced textiles. This research aims to identify gaps and propose agendas for better understanding and promoting sustainable consumption patterns within the fashion industry [8]. Simultaneously, the textile industry must address its wastewater challenges. Advanced Oxidation Processes (AOPs) are being explored for treating textile wastewater, which often contains persistent organic pollutants and dyes. Techniques such as Fenton, photo-Fenton, ozonation, and photocatalysis are assessed for their efficiency in degrading these contaminants, highlighting their potential to meet stringent environmental discharge standards and contribute to sustainable water management [9]. Lastly, the role of technology in ensuring ethical and transparent supply chains is becoming increasingly important. Blockchain technology, for example, is being investigated for its potential to enhance sustainability in fashion and textile supply chains by improving transparency, traceability, and accountability from raw material sourcing to product delivery. This helps combat issues like unethical labor practices and environmental pollution, fostering more trustworthy and sustainable textile ecosystems [10].
