The effects of SS:WG mixing ratio, alkali agent concertation, sintering temperature, and sintering duration on the physical properties of the fabricated FT, including bending strength, bulk density, water absorption, and porosity were investigated. The results indicated that under the optimal conditions of an SS:WG mixing ratio of 1:3, a solid–liquid ratio of 2 g/g, a sintering temperature of 750 °C, and a sintering duration of 60 min, the fabricated FT had a bending strength of 22.5 MPa, a bulk density of 1.31 g/cm³, a water absorption of 17.8%, and a porosity of 18.3%, meeting the CNS-9737 and ISO 13006:2018 for external and internal uses. The carbon dioxide (CO₂) emission of the proposed approach was reduced by more than 50% compared to traditional methods. The results demonstrated that the simultaneous waste valorization of SS and WG could be achieved for resources sustainable utilization. In addition, the eco-friendly fabrication of FT could also be achieved through reducing the required sintering temperature.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 2","pages":"1228 - 1244"},"PeriodicalIF":2.7,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564326","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}

In this study, 600 international students from 15 universities in five cities in Zhejiang Province were targeted, and a semi-organizational citizenship environmental behavior (SOCBE) analysis framework was constructed from three dimensions: individual cognition orientation, peer relationship orientation, and university organization orientation, to reveal the main influencing factors and pathways of LCEB. The results showed that (1) LCEB of international students studying in China is a multidimensional SOCBE concept, in which university organization orientation (0.437) &gt; individual cognition orientation (0.341) &gt; peer relationship orientation (0.275). In a semi-organized environment, both university organizations and peer relationships have a significant mediating effect on the impact of LCEB on individual international students, accounting for 58.2% of the contribution. (2) 16 observed variables influence the LCEB of international students in China. Among them, S13 (collective activity organization) has the greatest impact on the LCEB of international students, while S8 (guided by Chinese peers) and S9 (guiding Chinese peers) show the least data. It indicates that the relationship between international and Chinese students has the weakest influence on LCEB. (3) Family income, duration of study, and education level of study have significant positive effects on the LCEB of international students coming to China. In future, the management department of international students should fully recognize the role of individual cognition as the main body of SOCBE and focus on strengthening low-carbon environmental education and “Dual-carbon” knowledge propaganda and guidance for international students who come to China for a short period. In addition, it is necessary to focus on the guiding role of S13 and strengthen the interactive and experiential low-carbon environmental practice activities.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 2","pages":"1192 - 1213"},"PeriodicalIF":2.7,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564314","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}

With a shortage of natural aggregates, RCA, derived from construction and demolition (C&amp;D) waste, offers a solution to environmental and resource challenges. India, producing 150 million tons of C&amp;D waste annually with only 1% recycled, presents a significant opportunity for RCA utilization. This research includes compaction, California bearing ratio (CBR), and permeability assessments to compare RCA and CCA. RCA showed higher porosity and irregular particle shapes, resulting in lower maximum dry density (MDD) and higher optimum moisture content (OMC) than CCA, yet meets the minimum CBR requirement for granular sub-base applications. However, RCA's lower permeability and higher breakage rates during compaction necessitate tailored mix design and compaction practices. Despite these challenges, RCA offers environmental benefits, such as reduced reliance on natural aggregates and minimized waste generation. Recommendations include advanced processing techniques to remove residual cement paste and blending RCA with CCA or stabilizing agents. This study highlights RCA’s potential in sustainable development, emphasizing the need for meticulous processing, quality control, and proper mix design to ensure effective use in pavement applications.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 2","pages":"1174 - 1191"},"PeriodicalIF":2.7,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564312","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}

Furthermore, the study aims to comprehensively analyze the hygroscopic properties of these bio-based gypsum composites, comparing them to traditional gypsum boards. To better understand the hydric behavior and particularly the relationship between the porous microstructure and the different properties, several tests including porosity, capillary absorption, sorption isotherm, water vapor permeability, and moisture buffer value (MBV) were performed for various formulations. Moreover, it shows that the biobased composite exhibits a remarkable moisture absorption capacity, nearly 15 times higher than that of the reference sample, and displays a high-water vapor permeability, owing to a significant enlargement in critical pore size. Likewise, all gypsum formulations display MBV values exceeding 2.00 g/(m².% RH) indicating an excellent ability for moisture regulation. Finally, the findings highlight the potential to create innovative gypsum material, using recycled cellulose waste to provide natural ventilation and moisture regulation through a circular economy approach.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 2","pages":"1140 - 1158"},"PeriodicalIF":2.7,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564309","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}

Pyrolying sewage sludge to give sludge biochar is an attractive way of utilizing sewage sludge. However, sewage sludge has a low carbon content, low specific surface area, and underdeveloped pore structure and poses environmental risks because of the heavy metal content. Co-pyrolysis of sludge with other solid wastes to give composite sludge biochar (CSBC) can optimize the physicochemical properties and decrease the environmental risks. The excellent physical and chemical properties of CSBC make it suitable for use as an adsorbent to remove pollutants from wastewater. Here, progress in preparing and using CSBC is reviewed. CSBC prepared at high temperatures has a larger specific surface area, which is favourable for physical adsorption. Low-temperature CSBC is more likely to perform chemical adsorption because of more functional groups produced. In addition, adding biomass waste improves the specific surface area, porosity and oxygen functional group content in CSBC, and that enhances the removal of both organic and inorganic pollutants in wastewater. CSBC prepared by adding non-biomass waste containing certain elements (such as Ca) has excellent adsorption performance for target pollutants (such as heavy metals). The conclusion is that CSBC is a promising material that can be used to remove pollutants, manage wastewater, and utilize solid waste.

The fuel ratio and hot compressive strength are important properties as an alternative fuel to coke used in industrial furnaces. From the experimental results by the direct-densification molding method, it was found that the increase in pressure during molding did not have a significant effect on improving the fuel ratio, and there was a limit to the rate of substitution. On the other hand, it was confirmed that the two-step torrefaction densification molding method provided a greater improvement in both fuel ratio and hot compressive strength compared to the direct-densification molding method. This is because the lignin binder effect becomes higher because the torrefied biomass sample is molded at a torrefaction temperature. From the above, it is expected that the densified biofuel produced using the proposed two-step torrefaction densification molding method can make a significant contribution to the coke replacement rate in industrial furnaces.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><img></picture></div></div></figure></div></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 2","pages":"1121 - 1128"},"PeriodicalIF":2.7,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564374","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}
