Fecal sludge (FS) can serve as a feedstock for briquette production. However, the physical and chemical qualities of the briquettes produced using FS and different binding materials are still inadequate. This article examines the physical and combustion properties of carbonized FS bio-briquettes made using five different binders, namely, waste paper (WP), cooked banana peels (CB), non-cooked banana peels (NB), cooked cassava peels (CC), and non-cooked cassava peels (NC). Bio-briquettes were made at various binder ratios (0%, 25%, 50%, and 75%) using a locally fabricated manual pressing machine. Overall, the study discovered that all bio-briquettes fabricated can be utilized for heating and cooking; however, the type and quantity of binders employed influence their quality. The study concluded that FS bio-briquettes blended with 75% WP binder were the best, outperforming others in many tests including drying rates (6 days), physical tests (passed shattering [95%], water boiling [240 s], and tumbling tests [100%]), and burning/thermal efficiency (19.23 MJ/kg). The study suggests further research to be conducted on combining FS with other biomass feedstocks to decrease volatile matter and emissions in bio-briquettes made with FS and non-carbonized binders.</p>\u0000 </div>","PeriodicalId":35327,"journal":{"name":"Environmental Quality Management","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142447596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Observations were carried out at certain time intervals for 60 days with routine measurements of pH, electrical conductivity (EC), seed germination index (GI), survival rate (SR), and C/N ratio. The results showed that all types of MPs caused a decrease in the C/N ratio compared to the control, with the high-density polyethylene (HDPE) MPs treatment showing the most significant decrease (from 21 to 9.42).

However, their widespread use has led to significant environmental concerns. One of the major issues is their persistence in the environment, where they accumulate and cause contamination. This problem is particularly severe with plastic packaging and microparticles used in cosmetic products. As a result, the cosmetics industry started producing environmentally sustainable glitter. “Biodegradable” glitter is available in distinct compositions, mainly with a central base composed of a biodegradable material. This review focuses on academic research and patents related to glitter and biodegradable glitter, aiming to classify and compare commercially available options. Furthermore, this review analyzes scientific research on conventional glitter and its conclusions regarding environmental impact. For this, we used the keywords “glitter,” “biodegradable glitter,” “eco-friendly glitter,” “natural glitter,” and “sustainable glitter” in the databases of Wiley, Science Direct, Springer, and Clarivate Analytics ISI—Web of Science. We also performed a bibliometric analysis using the keyword “glitter” in the Web of Science database to obtain a bibliometric map of publication trends in the field using VOSviewer software. The products identified in the search were analyzed for their components and biodegradation potential. These products were classified as “biodegradable” if they were composed entirely of biodegradable constituents and as “eco-friendly” if only a portion of their constituents was biodegradable. We observed that several glitter products are incorrectly classified as biodegradable, demonstrating the need for standardized terminology that accurately reflects the composition of the glitter particles. Patent applications indicate a growing interest in developing environmentally safe glitter particles in recent years. Studies on conventional glitter mainly focus on its environmental impact or discuss analyzes for the identification and classification of glitter particles. The data gathered highlight the gaps in the field, mainly related to glitter production methods and the standardization of biodegradable glitter.

The decreasing order of concentration of HMs along the basin is Cr &gt; V &gt; Ni &gt; Zn &gt; Cu. The paper spotlights the pollution grade in sediments, assessed by the geo-accumulation index (<i>I</i><sub>geo</sub>), contamination factor (<i>C<sub>f</sub></i>), pollution load index (PLI), and enrichment factor (<i>E<sub>f</sub></i>). The assessment of ecological risk is studied as potential ecological risk index (RI), toxic risk index (TRI), and modified hazard quotients (mHQs). As per the <i>I</i><sub>geo</sub> and <i>C<sub>f</sub></i>, V and Cr concentrations are higher in the region. Further, PLI confirmed that 35% of samples exceeded the limits of sediment quality guidelines. The RI and TRI values show that a higher ecological risk is associated with Ni, V, and Cr and with Cu and Cr, respectively. Additionally, the 23% Ni and 20% Cu samples from mHQ indicate the severity of pollution in the aquatic environment. The inputs from anthropogenic and natural sources change the concentration of these HMs along the region. Moreover, the study of CIA and plagioclase index of alteration plots confirmed the low to intense weathering conditions. The statistical approach shows the linkage between Cr–V, Cu–Zn, and principal component analysis–derived prominent sources: industrial and agricultural runoff, as well as higher silicate weathering, contribute to the HMs concentration in the region. The Kabini River passes through different climatic and land-use domains of Kerala and Karnataka, which eventually regulate the HM concentration and geo-environmental processes in the region and affect the health risk to humans in one or the other way.

In the present study, social accounting literature is reviewed through bibliometric techniques, and the vast body of research associated with social accounting is systematized to identify major trends, the most successful authors, methodological variety, and topic relevance. Bibliographic data are retrieved from Scopus and Web of Science databases. Data analysis is performed using Biblioshiny R and Python programming languages. The corpus includes publications from 1946 to March 2024, and 2286 publications remain in the final sample. The results indicate a 6.2% growth rate per year, and the leading contributing country is the UK, followed by Australia, Italy, and the USA.
