In this study, through active ingredient separation, selective leaching and stepwise chemical precipitation develop a new method for the selective recovery of lithium from spent LiFePO₄ batteries by using sodium persulphate (Na₂S₂O₈) to oxidize LiFePO₄ to FePO₄. The impact of various variables on the efficiency of lithium leaching was investigated. Moreover, a combination of thermodynamic analysis and characterization techniques such as X-ray diffraction and X-ray photoelectron spectroscopy was employed to elucidate the leaching mechanism. It was found that 98.65% of lithium could be selectively leached in just 35 minutes at 60°C with only 0.2 times excess of Na₂S₂O₈. This high leaching efficiency can be attributed to the stability and lack of structural damage during the oxidation leaching process. The proposed process is economically viable and environmentally friendly, thus showing great potential for the large-scale recycling of spent LiFePO₄ batteries.</p>","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"265-273"},"PeriodicalIF":4.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12946229/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139546652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under optimal conditions, the prediction accuracy for carbon, hydrogen, oxygen content and lower heating value (LHV) reach 97.74%, 91.22%, 91.28% and 97.02%, respectively. Notably, models utilizing 10 selected key peaks demonstrated superior performance compared to those employing raw LIBS spectra or principal components, especially with the absolute difference reaching 14.57% for O content prediction. Interpretability analysis showed that C2 swan bands had highest effects impacts on carbon, oxygen content and LHV prediction, whereas H I line was essential for hydrogen content prediction.

Steel slag, a typical metallurgical solid waste, has been demonstrated to enhance the buffering capacity of digestion systems, thereby increasing methane production and achieving 'waste treatment using waste'. However, its efficacy under high-shock loads in FB is uncertain. Pulse feeding experiments simulating FB were conducted to analyse the system's impact resistance with steel slag addition and investigate its enhancement mechanisms. The addition of steel slag improved the methane production rate under various shock conditions, with a particularly notable enhancement under concentration shock. This scenario also saw a significant increase in the generation of soluble chemical oxygen demand and its utilization by microorganisms. This can be attributed to the enrichment of hydrolytic bacterial phyla (Firmicutes) and genera (<i>Gelria</i>), with functional gene analysis revealing an increase in genes associated with Fe(III) reduction and CO₂-to-methane pathways.

Focus groups, observations, analysis of existing materials and a review of the literature identified barriers in relation to capability, opportunity and motivation to compost packaging. The intervention addressed the identified barriers through clear and distinctive labels on packaging, matching bin signage, a motivational video and an onboarding presentation for workplaces. The intervention was implemented in three workplaces and evaluated using a pre-post design. The intervention led to sustained increases in compostable packaging in compostable bins and reduced contamination. A post-intervention survey and roundtable event suggested that the intervention was acceptable to workplace leads and employees.

However, the role of digitalization in waste management (WM) is underexplored, and the literature remains fragmented. This study explores the synergy between CE principles in tourism and decarbonization in the waste sector through digitalization, using case studies from Taipei (Republic of China) and Sukunan (Indonesia). By examining the integration of digital tools in WM systems, the study highlights how these cities leverage technology to promote net-zero emissions and sustainable practices, particularly in the context of tourism. The research employs a mixed-methods approach, combining qualitative data from focus group discussions, semi-structured interviews and secondary data analysis. The findings reveal that digitalization has significantly improved WM efficiency, resource recovery (RR) and carbon footprint reduction in both study areas. Notably, the study demonstrates that tourism plays a role in driving these digitalization efforts, particularly through the adoption of CE practices in WM. The results suggest that digital solutions, when tailored to local contexts, can accelerate decarbonization and enhance sustainability. In Sukunan, technological adoption generated 780 new jobs and raised average household incomes by USD 45 monthly. These initiatives reduced landfill waste by 30% and cut CO₂-equivalent emissions by about 0.3 million metric tonnes annually. Taiwan's 'Pay-As-You-Throw' (PAYT) system is a benchmark, showcasing effective WM and resource recovery practices. Digitalization is projected to trim WM costs by 35%, reduce annual expenses by 3.6%, generate USD 493 billion in revenue over decades and subdue global CO₂ emissions by 15% by 2030. Overall, this work emphasizes the potential for replicating such strategies in other cities, with consideration for local conditions, to achieve sustainability and decarbonization goals in the tourism and WM sectors.</p>","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"1605-1624"},"PeriodicalIF":4.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143754771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study is to determine the elements that significantly impact the intention of mobile phone repairers to carry out separation of e-waste. The integrated model incorporates Self-Determination Theory (SDT) factors (viz., amotivation, external regulation, identified regulation, intrinsic motivation, introjected regulation and integrated regulation) and Institutional Theory (IT) factors (viz., coercive pressure, mimetic pressure and normative pressure). Empirical data were collected through a printed questionnaire survey, with a total of 198 valid respondents. Moreover, this research utilized a hybrid data analysis method, using partial least squares structural equation modelling and artificial neural network to assess the model. The findings of this study indicate that all the SDT and IT factors are supported, except coercive pressure.

Effective strategies are crucial to mitigate impacts, maximising biowaste's valorisation. This article presents a systematic literature review on using life cycle assessment (LCA) to evaluate municipal biowaste treatment facilities. The primary objective was to analyse how LCA is applied to assess the environmental efficiency of mechanical and biological treatment involving composting and anaerobic digestion (AD)-based systems. The article addressed the methodological heterogeneity across previous LCA studies, identifying critical gaps and challenges regarding standardisation and result comparability. It underscores the importance of accurately considering environmental indicators and emission factors, as these significantly affect overall LCA outcomes. Results show that most publications focus on Europe and Asia, highlighting a research gap in regions like Africa. The organic fraction municipal solid waste is the predominant feedstock, and 1 tonne of biowaste was the frequently used functional unit, reflecting the upstream impacts of waste. The most recurrent system boundary was the cradle-to-grave, offering a comprehensive analysis as it covers all stages of biowaste treatment from collection to disposal. The studies highlight the environmental benefits of AD-based systems through energy production compensations, particularly in reducing global warming potential, compared with other treatment operations such as landfills. While replacing mineral fertilisers with digestate and compost is very well discussed, it raises concerns about heavy metal content and nutrient availability. Therefore, selective collection of organic waste is crucial to improve compost quality and AD efficiency, though it increases transportation costs.</p>","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"1509-1524"},"PeriodicalIF":4.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12476467/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143721596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
