Traditional methods to mitigate plastic pollution are often inadequate, prompting the need for innovative and sustainable solutions. Agricultural waste or by-products (AWBP) are underutilized sources of adsorbents for environmental pollution control, particularly for microplastic and nanoplastic removal. Despite their low cost and high adsorption capacities, AWBP are frequently burned, dumped, or placed in landfills. Most importantly, there remains a notable gap in research, i.e., a systematic review of AWBP-based adsorbents for the removal of microplastics and nanoplastics, which is the novelty of this review. Therefore, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method, this study reviewed the use of hydrochar, biochar, and activated carbon (collectively termed nature-based adsorbents) for the removal of microplastics and nanoplastics, focusing on their sources, properties, adsorption characteristics, and performance. The principal findings and major conclusions indicate that these adsorbents can achieve up to 100 % adsorption efficiency for the removal of microplastics and nanoplastics. Environmental factors such as pH, temperature, and co-existing species can influence adsorption performance. Functional groups like -COOH, -OH, and -C<img>O enhanced adsorption efficiency. Multiple mechanisms, including physisorption and chemisorption, contributed to high adsorption capacities. The pseudo-second-order kinetic model best described the adsorption processes, with the Langmuir isotherm providing the best fitting. Additionally, these adsorbents offer long-term carbon sequestration and align with several Sustainable Development Goals. This review highlights current knowledge gaps and provides recommendations for future research to further improve this technology.</div></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"5 ","pages":"Article 100119"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143528914","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}

This study focuses on ternary blended alkali-activated concrete (TBAAC) using fly ash, ground granulated blast furnace slag (GGBS), and silica fume as binders. It also aims the replacement of sodium silicate (SS) solution with neutral grade sodium silicate (NGSS) solution with a silica modulus (SiO₂/Na₂O) of 3.12 to improve the fresh and hardened properties of TBAAC. In this context, the effects of silica fume and alkaline activators are studied to determine the optimum mix design and to evaluate the fresh and hardened properties of TBAAC cured under ambient conditions. To investigate the performance of TBAAC, various experiments were carried out to measure its workability, compressive strength, splitting tensile strength, flexural strength, regression analysis and microstructural characteristics. The results show TBAAC of 40 % fly ash, 50 % GGBS and 10 % silica fume resulted in higher mechanical properties, including compressive strength (74.12 MPa), splitting tensile strength (18.46 MPa), and flexural strength (20.45 MPa). The results of the XRD, SEM and EDX analysis show the formation of C-A-S-H, C-S-H, and N-A-S-H gel, indicating a densified matrix with fewer cracks and pore spaces. Furthermore, the Life Cycle Assessment (LCA) results demonstrate that the use of NGSS, with its improved environmental profile, leads to a lower environmental impact, contributing to a significant reduction in the carbon footprint of TBAAC and enhancing the sustainability of construction materials. The findings suggest that using NGSS-based TBAAC is advisable for construction applications, offering practical implications for reducing environmental impact while maintaining high performance in construction projects.</div></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"6 ","pages":"Article 100122"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143577010","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}

Despite being a major greenhouse gas, CO₂ holds significant potential as a sustainable feedstock for chemical production. It can serve as a solvent, a preservative, a raw material for producing fuels, carbonates, polymers, and chemicals, and as a recovery agent for processes such as enhanced coal bed methane and oil recovery. This review highlights significant progress made in CO₂ capture and its integration into various industrial applications. While technologies such as adsorption, absorption, membrane separation, and cryogenics have shown promise, challenges related to cost, scalability, and the efficiency of capture and utilization continue to pose significant barriers to widespread adoption. Innovative strategies, including integrated carbon capture and conversion (ICCC) and integrated carbon capture and utilization (ICCU), present promising pathways to reduce costs by combining capture and utilization processes within a single facility. Additionally, catalytic processes and biological systems, such as microalgae and microbial strains (e.g., acetogens), are paving the way for sustainable CO₂ conversion into high-value products. Successful large-scale deployment of these technologies will require sustained interdisciplinary collaboration, robust policy frameworks, and increased investment in research and development. Prioritizing sustainable energy development and management offers the potential to significantly reduce anthropogenic CO₂ emissions while creating useful products.

In simulated treated wastewater, the adsorption of the nutrient was enhanced in the presence of Ca²⁺; however, the formation of insoluble Ca/P deposits on the adsorbent surface significantly changed the adsorption dynamics and disturbed the recovery of Phosphorus using the usual alkaline desorption method.

However, research has tended to study the two climate extremes in isolation. In this study, the Analytic Hierarchy Process (AHP), a Multi-criteria Decision Method (MCDM), together with Geographic Information System (GIS) and geostatistical techniques were used to simultaneously detect and assess drought and flood risks in the Olifants River Basin in South Africa. The drought and flood risk maps were delineated and overlaid on the smallest water management units to identify sub-basins at risk of either drought or flooding. Results indicate that low-lying areas are at risk of floods but can resist drought conditions for long periods as water accumulation allows the soils to retain water for prolonged periods. Whereas high-altitude areas quickly show drought stress as the shallow soils on steep slopes are incapable of retaining water for longer periods but are generally at low risk of floods.
