It helps reduce the need for primary raw materials and prevents the incineration or landfill disposal of textile waste. To foster textile circularity, it is essential to use these recycled fibres as secondary raw materials for textiles. The focus of our study was, therefore, to create quality yarns for making knitted fabrics for long-lasting garments. In this study, mechanically recycled post-consumer cotton and linen were ring-spun into yarns. Recycled cotton (rCO) was blended with virgin cotton (CO) in ratios of 30/70, 50/50, and 70/30, and with virgin viscose (CV) at a 50/50 ratio. Recycled linen (rLI) was blended with virgin viscose in ratios of 30/70 and 50/50. The yarn appearance, breaking tenacity, and elongation were evaluated and compared to virgin viscose and cotton yarns. The knitting performance of rCO/CO 50/50 yarn and reference 100 CO yarn was assessed by knitting different knit structures and pattern designs using a flatbed knitting machine. Additionally, the abrasion resistance of the two yarns knitted into single jersey fabric was tested using the Martindale method, and the samples were inspected using scanning electron microscopy. Increasing recycled cotton and linen content in ring-spun yarns decreased yarn strength and increased the uneven appearance. In addition, the rCO/CO jersey fabric showed higher wear under abrasion than the reference 100 CO fabric. The knit structure and pattern design had a central influence on knittability and fabric appearance when using yarn containing recycled fibres. Therefore, these factors should be considered to promote the use of recycled fibres for creating long-lasting textile products.</div></div>","PeriodicalId":101276,"journal":{"name":"Waste Management Bulletin","volume":"3 1","pages":"Pages 76-86"},"PeriodicalIF":0.0,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143153713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results obtained in this work revealed that incorporating different loadings of plastic-derived-MWCNTs onto the PSF polymer matrix impacted its surface properties, and improved flux, and removal efficiency.

This study converted OS into char-(OSC), including both pristine-OSC and ZnCl₂-activated-OSC, for the removal of organic pollutants from refinery wastewater (WW) with a high COD concentration (89,233 mg/L). ZnCl₂-activated-OSC produced at 400 °C (SB-Zn-400) showed superior adsorption capacity compared to pristine-OSC, due to enhanced oxygen-containing functional groups, crystallinity, thermostability, and superior degradation (OS). The adsorption process demonstrated rapid COD removal, reaching equilibrium within 2 h and achieving a 28 % reduction in COD. The adsorption capacity was found to be 420.5 mg-COD/g-OSC. SB-Zn-400 exhibited heterogeneous surface properties and supported multi-layer adsorption, with hydrogen-bonding and π–π interactions likely adsorption mechanisms. Moreover, the total concentration of organic compounds in PR-WW was &gt;2700 mg/L, and SB-Zn-400 reduced this concentration to 34 mg/L, achieving &gt;98 % removal. Although the adsorption treatment reduced the inorganic parameters of PR-WW, leaching of Mn, Ni, and Zn was observed, likely due to the nature of OS and the ZnCl₂-activation process. Thermal regeneration of spent SB-Zn-400 allowed the reuse of OSC, with adsorption efficiency remaining higher than that of pristine-OSC, indicating that SB-Zn-400 has potential to be reused.

However, the process generates reverse osmosis concentrate (ROC) or reject as a byproduct, which poses significant environmental concerns. One of the primary issues with ROC is the presence of organic micropollutants (OMPs). These pollutants are found in substantial concentrations in reject water, raising concerns about their potential ecological and health impacts. This review provides a summary of the characteristics of ROC from urban wastewater treatment plants, focusing on the concentrations and types of OMPs present. The study shows that ROC contains a variety of dissolved organic compounds, dissolved ions, and organic micropollutants, making its treatment a challenge. The paper discusses various technologies studied for the removal of OMPs in ROC, including adsorption, advanced oxidation processes (AOPs), and other methods. Adsorption is identified as an effective method for the removal of OMPs, although some compounds show lower removal efficiencies. AOPs also have good removal capabilities but at the cost of forming potentially harmful byproducts. Emerging technologies such as forward osmosis combined with adsorption, constructed wetlands, and other microbial processes show promise but require further research for practicality. This paper thus underscores the necessity for continued innovation and optimization in ROC treatment methods to mitigate the adverse effects of OMPs on the environment and public health.</div></div>","PeriodicalId":101276,"journal":{"name":"Waste Management Bulletin","volume":"2 4","pages":"Pages 249-260"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143162014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cotton biomass, mainly comprised of cellulose, hemicellulose, and lignin, represents a sustainable feedstock for the fermentative production of value-added bioproducts using microorganisms. Advances in microbial biotechnology have led to the effective valorization of cotton biomass and processing waste into valuable products. To date, cotton-based waste biomaterial has been utilized for microbial production of biofuel, hydrogen, biomethane, enzymes, organic acids, bio-enriched compost, and as a substrate for mushroom cultivation. Furthermore, the use of cotton biomass for developing fungal mycelial-based composite and eco-friendly packaging material is documented. Cotton seed meal, an essential byproduct of the cottonseed industry, is converted into more proteinous products and bioactive peptides via microbial-mediated degossypolization and fermentation.

The elemental analysis confirmed that an increase in pyrolysis temperature led to a rise in the carbon (C) concentration, whereas conversely there is a reciprocal decrease in the levels of oxygen (O) and hydrogen (H). Consequently, biochar produced at high temperatures showed low (O/C) and (H/C) fractions. Surface area (gas adsorption) studies indicated that the biochar surface area and pore volume increase at higher pyrolysis temperature. In contrast, the pore size was found to decrease at high temperatures. It was found that increased pyrolysis temperature resulted in reduced biochar yield. Biochar for use in specific applications like as an adsorbent material is ultimately influenced by the pyrolysis temperature.
