Personal care and cosmetic products (PCCPs) contain microbeads and are one of the primary sources of microplastics which contribute to health and ecological risks. The aim of this study was to evaluate the presence of microbeads in a widely used PCCPs (facial scrubs) in the Indian market and the extent to which these microbeads can serve as vectors for toxic compounds like chromium under different environmental conditions. Four of the ten facial scrubs contained microbeads of size ranging from 220 to 600 µm. Based on FTIR analyses, two of the four tested samples (A and B) were made of polypropylene, while the other two samples (C and D) were made of polyethylene. Furthermore, the study revealed that PP microbeads, which are very common, could efficiently adsorb Cr (VI) (3.09 mg Cr/g). Adsorption of Cr (VI) on microbeads was greater in acidic and saline conditions indicating that microbeads can potentially act as vectors for toxic compounds in marine aquatic ecosystems. It was estimated that 4.7 x 10<sup>10</sup> microbeads, which amount to 3.8 tonnes of microbeads are released into the environment annually. Based on these results, policy measures for preventing the release of microbeads/microplastics into the environment are suggested.</p></div>","PeriodicalId":101276,"journal":{"name":"Waste Management Bulletin","volume":"2 3","pages":"Pages 229-240"},"PeriodicalIF":0.0,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949750724000671/pdfft?md5=304c36032bb9385cab9ed647f4cc9934&pid=1-s2.0-S2949750724000671-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141950757","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}

Characterizations of wood, leaves, barks, and pod wastes from <em>Prosopis africana</em> biomass were investigated based on the proximate, ultimate, and compositional analysis of pulverized samples of the <em>PA</em> biomass to determine their physical, thermal, and chemical properties towards assessing their potential for valorization to bioenergy. The lignocellulosic materials were characterized by scanning electron microscopy, energy dispersive X-ray, Fourier transform infrared spectroscopy, thermogravimetric analysis, and X-ray diffraction.

Key topics covered include digital technologies, data collection and management, resource optimization, product design optimization, lifecycle monitoring and assessment, predictive analytics and modeling, circular design and product lifecycle management, supply chain transparency and traceability, virtual reality (VR) platforms, etc. The study also highlights the potential benefits and challenges associated with the adoption of digital technologies in the context of circular economy initiatives and offers insights for practical implications and future research directions. By leveraging digital technologies strategically, organizations can drive innovation, overcome challenges, and accelerate progress toward a more sustainable and circular economy.</p></div>","PeriodicalId":101276,"journal":{"name":"Waste Management Bulletin","volume":"2 3","pages":"Pages 69-83"},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949750724000567/pdfft?md5=49686e598d4851385478b089037f2d0f&pid=1-s2.0-S2949750724000567-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141595899","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}
