This solvent, of concern to human and ecological health, must be replaced with less toxic alternatives. Accordingly, the objective of this study was to determine which potential solvents, compatible with PVdF binder within the cathode processing of LIBs, could replace NMP. This study followed the U.S. National Research Council’s <em>Framework to Guide Selection of Chemical Alternatives,</em> and thus assembled and compared data concerning ecological and human hazards, performance, and cost. Five solvents were assessed as alternatives to NMP, derived from an analysis of 948 cells of data (708 cells of hazard data, 54 cells of performance data, and 186 cells of cost data). Triethyl phosphate (TEP) and N-N’-dimethylpropyleneurea (DMPU) are found to exhibit reprotoxic properties, and dimethylsulfoxide (DMSO) raised concerns in all three data categories studied. The most promising alternatives to NMP were dihydrolevoglucosenone (Cyrene) and γ-valerolactone (GVL).

Data availability to assess the sustainability of individual EoL material management from individual AM processes is limited.

Due to rapid urbanization and population growth, freshwater resources are depleted, and approximately two-thirds of the world’s population will experience severe water scarcity by 2050. The coagulation-flocculation method demonstrates a viable solution for water treatment due to the minimal technical requirements, short treatment duration, and low material cost. Recently, starch-based coagulants have garnered significant attention due to their non-toxic nature, abundance, and cost-effectiveness. However, the coagulation efficiency of starch can be further enhanced through surface modification. The performance efficiency of starch-based coagulants largely depends on the modification technique, as it may influence the density of the surface charge. This review paper comprehensively discusses the coagulation mechanism of starch-based coagulants and the distinct methods for starch extraction. The removal efficacy of starch-based coagulants primarily depends on various physicochemical properties such as surface functional groups, zeta potential, and the elemental and morphological properties of the coagulant. Tailoring these properties is essential for developing a promising starch-based coagulant capable of effectively removing pollutants from water. Finally, the future prospects of starch-based coagulants are provided to highlight the exciting opportunities for sustainable water treatment and alignment with circular economy principles.</div></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"5 ","pages":"Article 100083"},"PeriodicalIF":0.0,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142442332","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}

Their Pollution Load Index (PLI) values varied between 2.83 and 52.98, and their degree of contamination was “Progressive deterioration”. The PLI values for groundwater ranged between 0.089 and 3.68, and the degree of contamination varied from “Baseline levels of pollutants” to “Progressive deterioration”. In general, the groundwater of the studied area had a PLI value of 0.477 (Baseline levels of pollutants), whereas the surface water had a PLI value of 11.453 (Progressive deterioration). The Water Quality Index (WQI) of groundwater was highly influenced by heavy metals, notably Arsenic (As) from lithologic origins, and Lead (Pb) from the burning of fuels in the brick kilns. In descending order, Pb&gt;Zn&gt;As&gt;Cr&gt;Ni metals were influencing the PLI, and the correlation matrixes demonstrated that the presence of heavy metals was associated with the PLI and WQI values.

The synthesis of the GNs from plastic waste was done as we previously reported in the steps of the pyrolytic process, where the copper turnings are used as catalytic templates in the present study. Because of the excellent catalytic efficiency towards breaking old carbon-carbon bonds and forming new carbon-carbon bonds, the copper turnings act as an excellent degradation catalyst and promote the growth of graphitic skeletons and, consequently, graphene nanosheets. The synthesized GNs showed a high conductivity of ∼ 1730 S/m. GNs thus synthesized is implemented for synthesizing GNs/polypyrrole nanocomposites, which is later investigated for the TE applications. The values of the Seebeck coefficient showed that the composite of GNs/polypyrrole performs as a p-type semiconductor. The TE figure of merit (ZT) for GNs/polypyrrole demonstrated good thermoelectric characteristics and showed a value of 3.75 × 10⁻⁶ at the temperature.

The novelty herein is to conduct a BIM-based parametric energy analysis of green building components for the roofs and facades, taking into consideration the climate classification and orientation of the building. The proposed framework of this study uses Autodesk Revit software and Autodesk Green Building Studio as BIM tools, and Minitab software as a parametric analysis tool to estimate the energy performance of several alternative components based on Energy Use Intensity (EUI) and Annual Peak Demand (APD). A case study of a residential building is examined in four cities within different climate zones in Brazil; Rio de Janeiro (climate zone 08), Macaé (climate zone 05), Petrópolis (climate zone 03), and Nova Friburgo (climate zone 02). The base model design of components of the building includes a reinforced concrete roof and ceramic masonry façade. The utilized alternatives are roof components (i.e. green roofs and expanded clay roofs), and green façade. This work insight using green façade for all elevations and green roofs to enhance energy efficiency in terms of EUI by (10,17 %) in Rio de Janeiro, (6,67 %) in Macaé, (11,43 %) in Pertópolis, and (16,43 %) in Nova Friburgo.

In many parts of the world, heavy metals such as Pb, Cd, and U, along with bacteria like <em>Escherichia coli</em>, have been found to exceed permissible limits in groundwater and other water sources that the public depends on for daily drinking water. To address this, we have synthesized a novel composite material consisting of Ag-impregnated hydroxyapatite-coated activated carbon nanoparticles embedded in alginate beads, for the simultaneous removal of heavy metals (U, Pb, and Cd) and <em>Escherichia coli</em> from drinking water. The material's efficiency was evaluated through a series of batch and column experiments. Batch studies indicate 90 % sequestration of U within 5 hours and Pb and Cd within 7 hours, while <em>Escherichia coli</em> (10⁷ cfu/mL) was eradicated instantly. The study confirms that sorption follows pseudo-second-order kinetics via chemisorption and ion-exchange mechanisms. Fixed-bed column studies, using a logistic growth model, showed strong agreement between theoretical and experimental parameters for the Bohart-Adams, Thomas, and Yoon-Nelson models. The beads demonstrated a high affinity for heavy metals, achieving complete removal and disinfection within an empty bed contact time of 1.12 minutes. Reusability studies indicate that even after the third regeneration and reuse cycle, removal efficiency remained about 95 % for U and Pb, and 85 % for Cd. Furthermore, the effects of variations in water quality parameters such as pH, dissolved carbonates, humic acid, and ionic strength (except for Cd) on removal efficiency were minimal.
