“…Cotton is the second-most important raw material after synthetic fibers, and as a result, more cotton waste is produced, either during the pre-consumer stage of production, such as when yarn, fabric, and apparel products are made, or during the post-consumer stage, when the waste is disposed of after the product's useful life has expired. Cotton textiles, which are >95% cellulose (Subramanian et al, 2022), may be handled to produce cellulose if the right solvent is found. Paper waste contributes significantly to municipal and industrial garbage, with an estimated 400 million tonnes generated yearly, including cardboard, office documents, and newspapers (Del Rio, 2022).…”

IntroductionA significant population growth and development in industrialization has led to the concurrent expansion in many sectors including agricultural activities and daily consumption (Zhang et al, 2022). Numerous everyday activities and industrial operations create garbage, and the amount of waste generated rises proportionately to the demand for goods (Sebastian and Louis, 2021). As a result, the issues related to resource management and garbage disposal are rapidly increasing. In addition to posing serious environmental risks, poor disposal and handling can have a detrimental effect on human health (Mrozik www.resrecov.com HIGHLIGHTS ➢ This review discusses recycling solid waste into watertreatment membranes. ➢ Circular economy solid wastes can be utilized to make membranes. ➢ Suitable biopolymers, plastics, and inorganics waste for membranes is introduced. ➢ Membrane fabrication and performance with recycled materials are discussed. ➢ Future perspectives on waste-derived membranes are suggested.

The fashion industry contributes to a significant environmental issue due to the increasing production and needs of the industry. The proactive efforts toward developing a more sustainable process via textile recycling has become the preferable solution. This urgent and important need to develop cheap and efficient recycling methods for textile waste has led to the research community’s development of various recycling methods. The textile waste recycling process can be categorized into chemical and mechanical recycling methods. This paper provides an overview of the state of the art regarding different types of textile recycling technologies along with their current challenges and limitations. The critical parameters determining recycling performance are summarized and discussed and focus on the current challenges in mechanical and chemical recycling (pyrolysis, enzymatic hydrolysis, hydrothermal, ammonolysis, and glycolysis). Textile waste has been demonstrated to be re-spun into yarn (re-woven or knitted) by spinning carded yarn and mixed shoddy through mechanical recycling. On the other hand, it is difficult to recycle some textiles by means of enzymatic hydrolysis; high product yield has been shown under mild temperatures. Furthermore, the emergence of existing technology such as the internet of things (IoT) being implemented to enable efficient textile waste sorting and identification is also discussed. Moreover, we provide an outlook as to upcoming technological developments that will contribute to facilitating the circular economy, allowing for a more sustainable textile recycling process.

“…The impact of these materials from production, consumption and final disposal on the environment is the subject of extensive research today. Due to the difficulty in recycling or adding value to the resulting textile waste, most textile waste is landfilled or incinerated, neither of which is environmentally sustainable [6]. Therefore, efforts are made to propose an easier and cheaper method to reduce the growing harmful effects of textile waste.…”

This study aims to investigate the effect of alkalization and chemical coupling methods on the surface and adsorption properties of waste cotton and cotton/polyester yarns. The simple and cheap alkali treatment was performed using 10% and 18% NaOH solution, while the chemical coupling method involved combining cotton and cotton/polyester yarns and fly ash, using sodium carboxymethyl cellulose and sodium alginate as binders. Morphological and surface characteristics of unmodified and modified cotton and cotton/polyester yarns were analyzed by scanning electron microscopy and Fourier transform infrared spectroscopy, while adsorption properties were assessed by the removal of lead and cadmium ions from aqueous solution. It was found that chemical modification with 18% NaOH solution positively affected the adsorption properties of only cotton yarns, increasing the removal efficiency of lead ions up to 75%. On the other hand, modification with fly ash improves the adsorption properties of both, cotton and cotton/polyester yarns, increasing the efficiency in removing lead ions by using sodium carboxymethyl cellulose, and cadmium ions by using alginate as a binder. Using the chemical coupling method, effective adsorbents are obtained starting from waste yarn, which gives it added value, the amount of non-degradable waste material can be reduced and the criteria of a cleaner environment and circular economy can be met.
