Nevertheless, due to aluminum impurities mixed in raw materials, Li(I) and Al(III) ions are easy to combine to form water-insoluble LiAlO₂ during reduction, affecting Li(I) ions’ water-leaching efficiency. In this study, the LiAlO₂ formation environment is analyzed. Thermodynamic analysis reveals that there is generally less spontaneity in the reaction of Li (I) ions with aluminum monomers compared to Al₂O₃, and the introduction of CO₂ can inhibit Li-Al-O substance production. Li-Al binding experiments show that there is almost no direct reaction between Li₂CO₃ and aluminum monomers, but under Ar atmosphere, Li₂CO₃ and Al₂O₃ can easily lead to Li-Al binding, a kinetic analysis considers that binding is controlled by chemical reaction, with an activation energy of 57.78 kJ/mol, and the activation energy increases to 88.028 kJ/mol with CO₂ atmosphere. Under reduced optimization conditions (reduction temperature: 500 °C, time: 6 h, and m_NCM: m_Al = 1: 0.25), the carbonation water-leaching efficiency can reach 95.1% for Li(I) ions and less than 1% for Ni(II), Co(II), Mn(II), and Al(III) ions. Thus, this work offers a theoretical basis for the industrial Li(I) ions’ recovery from aluminum-containing NCM materials.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 5","pages":"3463 - 3479"},"PeriodicalIF":3.0,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100645","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}

Composting experiments were conducted on alum sludge and ferric sludge recovered from a phosphorus removal system in a controlled temperature chamber. A 3:1 woodchip-to-sludge ratio, determined through preliminary trials, was used.

The final compost products were analyzed for organic matter, C:N ratio, and other key characteristics, with results compared to guidelines set by the Canadian Council of Ministers of the Environment (CCME) Class A compost. Both compost piles maintained thermophilic temperatures above 55 °C for over 15 days, facilitating effective pathogen reduction and decomposition. The final compost products met the CCME Class A standards, with C:N ratios of 12:1 (alum) and 17:1 (ferric), organic matter content exceeding 68% for both products, total organic carbon within 30–40% range, and moisture content of below 60%.

However, most studies have focused on the sustainability impact of a circular plastic waste management alternative rather than accounting for the sustainability aspects that currently concern society. This study aims to promote circular plastic waste management by addressing community perspective on five sustainability dimensions (social, economic, environmental, institutional, and technical). This study collected questionnaires from 1000 respondents using cluster sampling method based on residential area, with a distribution of 48.4%, 12.5%, 12%, 11.3%, 9.8%, and 6% of respondents coming from Jakarta, Bekasi, Bandung, Depok, Tangerang, and Bogor, respectively. The questionnaires revealed disparities in five sustainable dimensions, analyzed using paired t-tests, multiple linear regression, and binary logistic regression. The study discovered that reducing plastic waste is the main focus for transitioning to circular plastic waste management. The current amount of plastic waste was found to have the largest gap compared to what is expected by the community. Improving waste workers’ quality of life and raising public awareness of the environmental impact increased community willingness to separate and reuse plastic waste. Businesses that promote circular economy concepts also increase community willingness to buy recycled products. The accuracy of three models in predicting willingness to separate, reuse, and buy recycled plastic was 68.7%, 87.8%, and 86.4%, respectively. This study had practical implications for creating better working conditions for waste workers and increasing public participation in the circular economy. The findings also highlighted the importance of considering technical, institutional, and social dimensions in promoting sustainability and public participation in circular plastic waste management. Future research could use machine learning or simulation modeling to further explore these findings.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 5","pages":"3366 - 3389"},"PeriodicalIF":3.0,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10163-025-02294-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100537","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}

The aim of the study was to determine the status of management strategies of waste printers, ink, and toner cartridges in Windhoek, and develop a framework on ICT waste management techniques within the municipality, including critical stakeholders. Data was obtained from 60 respondents through structured questionnaires and open-ended questionnaires distributed to target groups. A comprehensive multivariate statistical procedure, including partial least squares structural equation, was employed. The findings highlight that management has a significant positive relationship with the management practices of ICT waste, with a <i>t</i>-value of 1.326 and a <i>P</i> value of 0.093. There is a significant positive influence of disposal on management and awareness of management of ICT waste. Consumption has a significant effect on the management of ICT waste, but has the lowest path coefficient. The partial least squares structural equation model (PLS-SEM) was used to analyze complex relationships between variables. The highest cumulative percentage of selected variables was 81.43%, with different eigenvalues and percentage variance from nine selected components. The reduced model showed a path coefficient of 0.200, which emphasizes a positive relationship between the independent variable and the latent dependent variable. The model had an <i>R</i>² value of 4%, indicating variations in the overall quality of the waste management process. The extended model showed a substantial <i>R</i>² value of 41.9%, and management had the highest path coefficient of 0.516. The path coefficients indicate a positive relationship between latent independent variables and dependent variables. It is suggested that the proposed model should be used to address management challenges of ICT waste. The model should provide strategic directions in ICT waste management and foster the adoption of sustainable oriented solutions.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 5","pages":"3416 - 3434"},"PeriodicalIF":3.0,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10163-025-02296-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100644","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}

In this study, we constructed a demonstration plant that could treat 35 t of wet sludge (dewatered, so the water content was 70%) each day at an actual sewage treatment plant. We adopted a step grate-type stoker furnace and used waste heat from sewage sludge incineration to generate electricity. We collected data for the power generated and consumed, from which we were able to estimate the greenhouse gas emissions. Using this method, we were able to generate more than 100 kW of electricity in each of the four seasons. The results of a case study based on an input of 24 t-ds/day show that, compared with the conventional system, the amount of energy required to generate electricity can be reduced by about 70%. Further, the test system produced surplus power.

Previous studies have explored the use of IOT in construction and geotechnical applications, but limitations such as inadequate strength development and environmental concerns have restricted its widespread adoption. The motivation for this study stems from the need for a sustainable and effective solution to repurpose IOT while addressing these challenges. This study investigated a sustainable approach to utilizing IOT as a backfill material by incorporating fly ash (FA) to enhance its mechanical properties. The mix proportions of FA to IOT were 3%, 6%, 9%, and 12%, and the maximum dry density, optimum moisture content, and strength parameters were analyzed. The morphological and mineralogical characterizations were also conducted for both materials. The optimum mix, containing 9% fly ash, achieved a maximum unconfined compressive strength (UCS) of 901.25 kPa at 28 days, exceeding the required strength for void filling (150–300 kPa) and approaching the threshold for free-standing wall support (1 MPa). The toxicity characteristics leaching procedure (TCLP) confirmed that the heavy metal concentrations in IOT are within permissible limits, ensuring environmental safety. These findings demonstrate the potential of IOT-FA composites as a cost-effective and eco-friendly solution for backfill applications in the mining and construction industries. By converting industrial by-products into functional materials, this study contributes to sustainable waste management and promotes resource efficiency in geotechnical engineering applications. </p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 5","pages":"3510 - 3525"},"PeriodicalIF":3.0,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100780","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}
