“…Although this may lead to the understanding that denim made with 100% cotton, in particular, will readily deteriorate in the environment, in practice a pair of such jeans can stay alive in the environment for a very long time, and therefore the negative environmental impact is very high. The literature reveals that the amount of waste jeans generated annually is estimated as 2.16 million tons and only 35-50% of this amount is collected in Western Europe in order to reuse or recycle it after sorting [13,[20][21].…”

Global denim jeans market size is over 70 billion dollars today, and it continues to grow with a compound annual growth rate (CAGR) of 2%. As a reflection of this annual growth, systems' waste generation also increases. Textile waste including denim accounts for nearly 5% of all landfill space, according to the Environmental Protection Agency (EPA). Today, efficient recycling technologies are essential to revive the waste generated. Recycling technologies potentially represent a new way to engineer products. This book chapter analyzes these different recycling technologies and their advantages and challenges and concentrates on denim fabrics produced with recycled content. Life cycle assessment (LCA) methodology is adopted to quantify and compare the environmental impact of recycled denim fabrics. The chapter concludes the challenges and the future of recycling, creating systems, and engineering of waste. The view of seeing waste as a raw material potentially represents a new opportunity to design circular systems.

“…Hu, Shang [ 64 ] have studied the use of catalytic ozonation for effluent reuse and reported that catalytic ozonation could regenerate cotton effluent and can be reused twice without compromising fabric quality. In order to regenerate spent cotton wastes for dyes and heavy metals removal, Yousef, Tatariants [ 65 ] have reported that leaching treatment is favourable when compared to incineration, which may further constitute a pollution effect. The authors carried out a leaching test for the removal of dyes from cotton wastes using nitric acid leaching and regenerated the used acid by activated carbon.…”

Cotton Wastes Functionalized Biomaterials from Micro to Nano: A Cleaner Approach for a Sustainable Environmental Application

The exponential increase in textile cotton wastes generation and the ineffective processing mechanism to mitigate its environmental impact by developing functional materials with unique properties for geotechnical applications, wastewater, packaging, and biomedical engineering have become emerging global concerns among researchers. A comprehensive study of a processed cotton fibres isolation technique and their applications are highlighted in this review. Surface modification of cotton wastes fibre increases the adsorption of dyes and heavy metals removal from wastewater. Cotton wastes fibres have demonstrated high adsorption capacity for the removal of recalcitrant pollutants in wastewater. Cotton wastes fibres have found remarkable application in slope amendments, reinforcement of expansive soils and building materials, and a proven source for isolation of cellulose nanocrystals (CNCs). Several research work on the use of cotton waste for functional application rather than disposal has been done. However, no review study has discussed the potentials of cotton wastes from source (Micro-Nano) to application. This review critically analyses novel isolation techniques of CNC from cotton wastes with an in-depth study of a parameter variation effect on their yield. Different pretreatment techniques and efficiency were discussed. From the analysis, chemical pretreatment is considered the most efficient extraction of CNCs from cotton wastes. The pretreatment strategies can suffer variation in process conditions, resulting in distortion in the extracted cellulose’s crystallinity. Acid hydrolysis using sulfuric acid is the most used extraction process for cotton wastes-based CNC. A combined pretreatment process, such as sonication and hydrolysis, increases the crystallinity of cotton-based CNCs. The improvement of the reinforced matrix interface of textile fibres is required for improved packaging and biomedical applications for the sustainability of cotton-based CNCs.

“…Note que uma vez que a fibra têxtil é disposta sem nenhum tratamento ambientalmente adequada trará impactos negativos para o ecossistema, porque, potencialmente, libera substâncias tóxicas para o solo e corpos hídricos no meio ambiente. De acordo com o estudo Yousef, et al (2020), os resíduos têxteis estão relacionados a liberação de gases do efeito estufa. Os autores citados enfatizam a importância do tratamento dos resíduos têxtil por tempo de duração que levam para se degradarem na natureza, como também reforçam a necessidade de economia circular dentro do ciclo produtivo industrial ou empresas de forma independentes (Sousa-Zomer, et al, 2018).…”

The objective of the work is to evaluate the waste management within two companies in the clothing sector, in the city of Belém, state of Pará, Northern Brazil. Through the concept of Circular Economy, which aims to increase the useful life of the product, reusing and recycling raw materials after consumption, the aim is to understand the process of generating fabric waste, as well as its collection and final destination, proposing improvements to the existing process. The information was obtained from the managers and employees of the companies, through a questionnaire and on-site observation. It was analyzed, mainly, the types of textile fibers used in the manufacture, the amount of waste produced and the management of waste, in addition to the information on the characterization of the enterprise. The results reveal that the largest company fits the EC principles, highlighting the innovation in defibrated textiles. The local company is in disagreement with the basic rules of conduct related to environmental legislation, requiring a Solid Waste Management Plan that allows the reuse of waste in order to reduce its production costs, as there is no textile recycling factory in Belém. It is concluded that the management and management of solid waste are fundamental for environmentally appropriate disposal and final disposal and, specifically, in the textile industrial sector, circularity can generate better productive efficiency.
