Greywater reuse and recycling is a financially sound and appealing solution for fulfilling future water demand. The reuse and treatment of grey water are based on the parameters such as BOD, pH, EC, turbidity, suspended solids, and other factors. The current investigative study is primarily concerned with describing segregated grey wastewater (bathroom, laundry, and kitchen) from diverse rural families and based on the socio-economic classes of staff members who live in the rural area of Karunya Nagar. The indicators examined showed considerable differences across different economic classes, according to statistical analysis. The results of the current study demonstrated that household habits, activities, and wastewater sources all have a significant impact on the characteristics of greywater. This research will be useful in developing a sustainable, cost-effective treatment system that will allow homeowners to safely recycle and reuse greywater produced by various sources. Emerging contaminants pose a great threat to human health. In light of this, the current study concentrates on qualitative and quantitative evaluations of emerging pollutants from several rural Indian household classes using gas chromatography mass spectroscopy(GC–MS) and high-performance liquid chromatography(HPLC).</p></div>","PeriodicalId":101255,"journal":{"name":"Total Environment Research Themes","volume":"6 ","pages":"Article 100053"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49714755","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}

Likely, the consideration of sustainable materials in the construction sector has become imperative for its long-term survival. Waste<!--> <!-->foundry sand (WFS), a by-product of the metal casting industries (ferrous and non-ferrous) is a viable alternative to replace natural sand in concrete. In this regard, various literature have reported WFS replacement in structural concrete in the last few decades. The present review extensively targets the suitability perspective of WFS replacement in concrete, specifically portraying a comparison of partial and full replacements with critical limitations for use in concrete. The review found that the partial optimum replacement level is in the range of 20–30% by weight with desirable mechanical properties and further increase in replacements tends to degrade the major mechanical properties of the concrete. In contrast, full replacement reported to reduce the workability and compressive strength of the concrete, thus making the replacement inappropriate for making structural concrete members. In essence, owing to the varied sources of generation of WFS and limited reports, further possibility of evaluating more results about durability and dynamic properties is feasible to make pertinent conclusions regarding the use of WFS in sustainable concrete development. As a current research gap, the study also recommended the use of strength enhancing waste products/low-cost additives at full replacement and agglomerate of waste foundry and other waste materials as a sand substitute could be explored for better and sustainable concrete production.</p></div>","PeriodicalId":101255,"journal":{"name":"Total Environment Research Themes","volume":"6 ","pages":"Article 100048"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49757118","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}

Urbanization, commercialization, and overpopulation are all key contributors to rising air pollution levels. The goal of this research is to examine long-term variations in Aerosol Optical Depth (AOD), vegetation, built-up, and their relationship in Jaipur, India using remote sensing and GIS techniques. For the present study, Multi-Angle Implementation of Atmospheric Correction (MAIAC), a combined Aqua and Terra MODIS product from 2000 to 2020 was obtained from Google Earth Engine (GEE). Results revealed the minimum and maximum AOD during the rainy and winter season respectively. Correlation analysis revealed that NO₂, PM_2.5, and PM₁₀ moderately correlated to AOD. Significant increase of more than 100 % during the winters was observed from 2000 to 2020, thus it becomes important to reduce the concentration of pollutants. Population growth has led to land consumption at a faster rate and therefore Land-use and Land-cover (LULC) changing patterns must be understood for efficient environmental management. Utilizing multispectral satellite images offers a thorough understanding of changes in the area. The Landsat series’ multitemporal satellite imagery (Landsat – 7 ETM+ and Landsat – 8 OLI) was used to map decadal LULC variations from 2000 to 2020. The overall accuracy of LULC classified maps is ranging from 78 % to 84 %, with a kappa coefficient from 0.72 to 0.80. Results showed that built-up land increased from 22.80 % to 44.2 %. A significant decline was observed for agricultural land (47.20 % to 25.5 %) in the last 20 years. The LULC change patterns for the years 2000, 2010, and 2020 varied significantly. For environmental sustainability, the LULC change should be continuously monitored in the future, thus it becomes important to monitor the changes and take steps to reduce the upsurge in air pollution for strategic planning, management, and informed decision-making.</p></div>","PeriodicalId":101255,"journal":{"name":"Total Environment Research Themes","volume":"5 ","pages":"Article 100027"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49709123","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}

The results conclude that macroeconomic variables are very important factors that determine renewable energy penetration in Nigeria. The relative effects of the resultant determinants graded income as the most important, followed by exchange rate and then inflation. The place of education and health human capital development is equally paramount to renewable energy penetration, among others. The study recommends among others, increase in renewable energy capacity by directly creating renewable energy jobs to increase its penetration and income which tops the list.

Rapid urbanization and the dispersion of industrial plants have an impact on environmental damage by discharging contaminants into the environmental systems. Bio-electrochemical systems (BESs) are novel techniques for transforming chemical energy to electrical energy (and vice versa) via microbes as catalysts. Some advanced novel green technology based on BESs, such as microbial carbon fuel cells (MCCs), plant-based microbial fuel cells (P-MFCs), and microbial electro-synthesis cells (MESs), can contribute to cleaning the environment by sequestering carbon dioxide (CO₂) while also producing value-added products from wastewater and CO₂. Treatment of wastewater with the generation of bioenergy and bio-fuel recovery is another additional benefit of using advanced BESs. In this review report, we realised that the MCCs have high coulombic efficiency and electricity generation capacity, while the MESs has high CO₂ sequestration efficiency. P-MFCs, on the other hand, have a high contamination removal capacity. However, there is no doubt that the MCCs, P-MFCs, and MESs systems have additional benefits, which are primarily based on the self-sustaining nature of microorganisms and other factors. This review explored the possible use of MCCs, P-MFCs, and MESs for wastewater treatment with electricity generation, reducing the CO₂ and production of value-added products.
