This paper examines the key challenges, trends, and opportunities in SWM, focusing on waste generation patterns, collection, transportation, treatment, and disposal methods in India. The major challenges identified include inefficient waste segregation, poor disposal practices, societal attitudes, and the unorganized informal sector. These problems, compounded by institutional weaknesses, inadequate funding, and slow adoption of technology, worsen the waste management crisis. Proper management of municipal solid waste (MSW) is essential for public health, environmental protection, and the achievement of sustainable development goals. This paper emphasizes the need for alternative waste management techniques, as nearly 90% of MSW is improperly disposed of in open dumps and landfills, posing significant risks to health and the environment. By forecasting future urbanization trends and their impact on waste generation, this paper evaluates effective treatment technologies for MSW in India. This study concludes with actionable recommendations and a unified framework, supported by data and case studies tailored to India’s socio-economic context, and aims at improving SWM practices and promoting long-term sustainability.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":807,"journal":{"name":"Waste Disposal & Sustainable Energy","volume":"7 1","pages":"127 - 150"},"PeriodicalIF":0.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143949716","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}

In this study, the leaching of fly ash by acetic acid was investigated. Key parameters, including time, acetic acid concentration, and fly ash type, were examined for their influence on calcium and heavy metal leaching. The physical and chemical changes in fly ash before and after leaching were analysed via the X-ray fluorescence (XRF), X-ray diffraction (XRD), and heavy metal leaching methods. The results showed that acetic acid effectively leached metals from different types of fly ash, as determined by the risk assessment code (RAC) and risk index (RI), and leaching with 0.25 mol/L acetic acid resulted in the lowest environmental hazard for fly ash. Moreover, adjusting the pH to below 11 during acid treatment, followed by washing with water, substantially reduced heavy metal leaching and increased the potential for safe resource recovery. A life cycle assessment (LCA) using the CML-2001 method revealed that the marine aquatic ecotoxicity potential had the largest environmental impact, accounting for 39.56% of the total index.

Water and acid washing along with thermal regeneration are commonly used to eliminate toxic substances from the catalyst surface, while these processes often result in the undesired loss of active components. In this research, an impregnation approach was adopted to replenish the depleted active constituents of the spent V₂O₅-WO₃/TiO₂ (VW/Ti) catalyst. Experimental investigations were conducted to evaluate the influence of Ce/P doping on both the SCR activity of this rejuvenated catalyst and its resistance to the detrimental effects of SO₂/H₂O exposure. The optimal performance is achieved with the Ce/P co-doped VW/Ti catalyst, demonstrating remarkable efficiency in removing nearly 100% of NO_<i>x</i> across a broad range of temperatures from 150 to 450 °C. The incorporation of a proper content of Ce serves to increase the VO_<i>x</i> surface density from a sub-monolayer state to a monolayer state and fosters the formation of more surface oxygen vacancies. This transformation positively contributes to enhancing both the catalytic activity and the resistance to SO₂/H₂O poisoning. Further treatment with H₃PO₄, although rendering the catalyst more susceptible to H₂O, achieves a delicate balance between its surface acidity and redox capabilities. This optimized state not only enhances the catalyst's robustness but also further widens the active temperature window.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":807,"journal":{"name":"Waste Disposal & Sustainable Energy","volume":"7 1","pages":"73 - 84"},"PeriodicalIF":0.0,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42768-024-00217-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143949446","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}

In many regions, sludge is typically characterized by a low organic matter content. Consequently, the selection of sludge treatment and disposal routes should be tailored to the specific characteristics of sludge in each region, considering its dual attributes of “resource” and “pollution”, and aiming to maximize environmental, economic, and social benefits. Using the current sludge treatment and disposal situation in Wuhan, China, this study conducted a quantitative assessment of carbon emissions, environmental risks, and economic benefits associated with several existing treatment and disposal routes from a life cycle perspective. The results suggest that for sludge characteristics with low organic matter content, co-incineration in coal-fired power plants or cement production processes is the most favorable option. Specifically, when the organic matter content of the sludge falls below approximately 40%, cement production is deemed the preferred process, whereas co-incineration with coal is favored when the organic matter content exceeds 40% but is less than 50%. Owing to the relatively low organic matter and nutrient contents of sludge, optimization of existing anaerobic digestion and aerobic composting processes can be achieved through collaborative treatment with other solid wastes. Moreover, the prevailing carbon trading prices in the Chinese carbon market are relatively low and do not significantly impact the selection of current sludge treatment processes. This study aids in the development of sustainable management strategies for sludge characterized by low resource and pollution attributes in the future.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":807,"journal":{"name":"Waste Disposal & Sustainable Energy","volume":"7 1","pages":"85 - 98"},"PeriodicalIF":0.0,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143949552","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}

Fourier transform infrared spectroscopy (FTIR) analysis corroborated the absence of chemical reactions between coconut oil and raw or modified PGPs. Scanning electron microscopy (SEM) micrographs provided visual evidence of successful coconut oil impregnation.

Effective methods for CO₂ capture and utilization are therefore necessary to achieve environmental sustainability. In this study, a novel method to capture CO₂ directly from ambient air is developed based on the bubbling of alkaline earth metal solutions, utilizing a simple do-it-yourself (DIY) device. In the bubbling process, ambient air passes through a diffuser to produce tiny air bubbles in an aqueous solution of alkaline earth metal halides (i.e., MCl₂, where M=Mg²⁺, Ca²⁺, Sr²⁺, and Ba²⁺) and sodium hydroxide. During this process, dissolved metallic ions interact with CO₂ molecules confined in the tiny air bubbles, forming metal carbonates. The depletion of CO₂ in the air flux was monitored by operando Fourier-transform infrared (FTIR) spectroscopy. The CO₂ capture efficiency was found to be dependent on the type of metal halide, its concentration, and pH level. Specifically, 0.10 mol/L MCl₂ aqueous solutions at pH=11 demonstrated efficiencies ranging from 90% to 52% in the following order: Mg &gt; Ca &gt; Sr &gt; Ba, with MgCl₂ exhibiting superior performance in the studied pH range of 6–11.

To address this potential shortage, this study proposes partial or total replacement of BFS with palm oil fuel ash (POFA), an agricultural by-product from the oil palm industry, in high-volume slag cement. The hydration characteristics, compressive strength development, and carbonation resistance of the resulting binary/ternary cementitious systems containing BFS or POFA are thoroughly evaluated. The results indicate that POFA is less reactive than BFS at an early stage (2 d or 3 d). However, as the curing time increased, the pozzolanic reaction of POFA became pronounced, significantly reducing the calcium hydroxide content in the hardened paste at later ages. The reactions of POFA and BFS further contribute to the increase in mechanical strength. This study revealed that incorporating 15% POFA in high-volume slag cement paste results in 8.6% greater compressive strength than cement paste without any supplementary cementitious materials (SCMs) after 56 d of curing. However, the addition of POFA diminishes the carbonation resistance of such ternary cementitious systems. Specifically, the carbonation rate increases by 16.9% to 95.0% when the proportion of POFA in high-volume ternary cement increases from 15% to 60%. This work provides valuable insights into a ternary cementitious system containing POFA and BFS, promoting the sustainable use of POFA as an SCM in cement-based materials.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":807,"journal":{"name":"Waste Disposal & Sustainable Energy","volume":"7 1","pages":"11 - 26"},"PeriodicalIF":0.0,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143949420","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}
