This study introduces a novel dolomite depressant, synthesized by combining sodium phytate (SP) and sodium silicate (SS), and evaluates its effectiveness in flotation. The impact of the combined depressant on the mineral surface properties and pulp characteristics during flotation was assessed using techniques, including contact angle measurement, bubble-particle wrap angle testing, turbidity testing, microscopy, SEM-EDS, and XPS. The results show that the depressant selectively adsorbs onto calcium sites on the dolomite surface, thereby increasing its hydrophilicity. It also acts as a dispersant, reducing particle agglomeration and improving pulp dispersion. Electrostatic potential (ESP) and average local ionization energy (ALIE) calculations were performed to identify the reaction sites, while molecular dynamics (MD) simulations and the Independent Gradient Model (IGM) were used to analyze the depressant-mineral interactions. The findings reveal that the SP-SS combined depressant self-assembles primarily through hydrogen bonding. The interactions between the depressant and the dolomite surface are predominantly driven by hydrogen bonding, coordination bonding, and steric hindrance, with SP playing a key role. This study highlights the potential of the SP-SS combined depressant for effective decalcification, offering valuable insights for optimizing flotation processes.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"42 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Therefore, this study aims to examine the role of Circular Economy Practices CEPs in decarbonizing the Chinese construction industry by identifying and prioritizing the most impactful strategies. To achieve this, the Fuzzy Delphi Method FDM was adopted to systematically refine and validate the set of relevant CEPs based on expert consensus, ensuring the inclusion of the most significant CEPs. Subsequently, the Decision-Making Trial and Evaluation Laboratory DEMATEL method was used to determine the causal relationships and influence levels among these CEPs, enabling the identification of key drivers for carbon reduction. Results show that supply chain optimization CEP20, adaptive reuse of materials CEP18, and bio-based materials CEP17 emerged as the most influential CEPs for reducing the industry's carbon footprint. Further, sensitivity analysis validated these findings' robustness, ensuring their practical application reliability. The study provides actionable insights for managers and industry stakeholders by highlighting the need for integrating CEPs into operational strategies. For example, optimizing the supply chain CEP20 can enhance material efficiency while adopting bio-based materials CEP17 encourages sustainable procurement policies. Policymakers are encouraged to develop incentives and regulatory frameworks that facilitate these transitions. By offering a structured framework, the results guide decision-makers in achieving tangible progress toward China's carbon neutrality goals, fostering both environmental sustainability and competitive advantage in the construction sector.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"3 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

To preserve HQ in the Yangtze River Basin, a multi-tiered protected areas (PAs) system, including nature reserves, scenic areas, and diverse types of nature parks, has been established in the Dongting Lake Eco-Economic Zone. Here, we assessed the conservation effectiveness of PAs system using the Propensity Score Matching-Difference in Differences (PSM-DID) model across a spatial grid of 10,301 grid cells (1 km × 1 km) and 96 individual PAs. Robustness for control variables and a placebo test for changes in the timing were conducted to ensure the reliability of the findings. The results indicated that the PAs system significantly enhanced HQ conservation at the spatial grid level compared with matched control areas, and substantial effects were observed 10 years post-establishment. Specific PA types—nature reserves, scenic areas, and forest parks —outperformed others in HQ conservation. However, the conservation effectiveness of overlapping areas of different PA types was low, which reflects shortcomings of the traditional design of the PAs system. Only 49.5% of PAs showed positive conservation effectiveness at the individual PAs level, which largely stemmed from the double counting of overlapping areas among different PA types. Additionally, the urban–rural gradient, tourism intensity, and management agency levels were significant determinants of conservation effectiveness. These findings offer pivotal insights for refining policy assessments and underscore the need for tailored management approaches to optimize the effectiveness of the PAs system and advance sustainable regional development.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"2 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Chemical recycling of plastic waste offers a perspective aligned with circular economy principles and carbon neutrality, utilizing plastic waste as a carbon source to replace fossil-based feedstock. This study conducts techno-economic and life cycle assessments, based on experimental data, to demonstrate the chemical recycling of expanded polystyrene (EPS) waste through depolymerization to produce recycled styrene monomer (r-SM). Process simulations were carried out to obtain mass and energy balances and equipment sizes. The simulation outcomes served as inputs for economic and life cycle assessments. Three cases were evaluated: Case 1) low-grade r-SM (>95 % purity) without using a solvent for dissolution, Case 2) low-grade r-SM (>95 % purity) by using THF as a solvent for dissolution, and Case 3) a high-grade r-SM (>99 % purity) without using a solvent. Case 3 offers the most economically viable option, with a minimum product selling price (MPSP) of $1.06/kg, comparable to virgin styrene monomer (v-SM). Sensitivity analysis identified EPS waste costs as the biggest influence on MPSP. The life cycle assessment (LCA) showed that all cases have a lower Global Warming Potential (GWP) than the production of v-SM, with Case 1 achieving an 89 % GWP reduction. Energy consumption is identified as the primary contributor to GWP results.

Additive manufacturing (AM) is particularly well-suited for metal remanufacturing and reverse logistics in high value industries like defense and aerospace, due to its adaptable processing capabilities and distributable manufacturing model. While previous studies have focused on the precision of metal AM repair, few have investigated its impact at the supply chain level. This study addresses this gap by exploring the integration of cloud-based AM services (CA-RMfg) to support reverse logistics in metal remanufacturing, reducing capital and technical barriers for small and medium enterprises (SMEs). A bi-objective reverse logistics model is developed within the CA-RMfg environment to optimize facility connections and manage network variabilities. The effectiveness of the model is demonstrated through a real-world case study of aircraft engine repair service providers in the state of Texas in the U.S., identified using the North American Industry Classification System NAICS code. Results indicate that a broader AM hub distribution reduces waiting times but increases average repair costs to over $640 per unit for SMEs due to facility underutilization. However, optimized AM hub allocations lower unit repair costs to approximately $250 for SMEs within the service area, offering a two- to threefold reduction compared to in-house AM facilities. Additionally, for large enterprises, in-house AM remains cost-effective, achieving up to a 20% savings through higher utilization rates and bulk material discounts, though with potential trade-offs in waiting times.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"58 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

To extend the application scenarios of LC<sup>3</sup>-based composites, this paper provides the first in-depth analysis of their mechanical performance at both room and elevated temperatures, along with the effects of fiber reinforcement. Our findings reveal that the LC<sup>3</sup> substitution rate can reach 50% to 60%, improving compressive strength, flexural strength, and ductility but negatively impacting tensile strength and high-temperature resistance. Temperatures of 400°C and 800°C are key thresholds, with severe strength loss occurring above 800°C. Compared to OPC-based composites, LC<sup>3</sup>’s complex composition and hydration products result in more severe microstructural damage at high temperatures. The inclusion of fibers, such as PP fibers, steel fibers, and modified polymer fibers, can reduce strength loss and prevent spalling at high temperatures. However, research on the high-temperature performance of fiber reinforced LC<sup>3</sup> (FRLC<sup>3</sup>) remains limited, and the failure mechanisms are not yet fully understood. This paper summarizes and compares existing research, proposing that future studies focus on key issues such as improving the LC<sup>3</sup> substitution rate in FRLC<sup>3</sup>, expanding fiber types, optimizing component design, and clarifying the fiber mechanisms, which are crucial for the development of high-temperature-resistant FRLC<sup>3</sup> composite materials.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"1 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

But high GHG emissions emanated from the movie industry have been overlooked. As GHG emissions are associated with climate change, understanding the dynamics of GHG emissions in the movie industry is important. Using the US movie industry as a case study, this study analyzes challenges and solutions to achieve low-carbon US movie industry through feedback loops and the system archetypes. This study finds that the US movie industry consists of several balancing loops and reinforcing loops, leading to four types of the system archetypes. Based on the four different system archetypes, it is found that the US movie industry has faced some barriers to achieve low GHG emissions. Moreover, the identified system archetypes suggest important points about reducing GHG emissions, especially in the US movie industry. The first point is the traditional production should follow sustainable movie practices such as the virtual production. The second point is the US movie industry should initiate some steps such as developing standard procedures and a transition plan to achieve the target of GHG emissions. The third point is while carbon offsetting should be minimized or regularly improved, the virtual production should be encouraged. The latter is important as the virtual production leads to lower GHG emissions and carbon offsetting only offers a temporary solution in decreasing GHG emissions.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"8 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

This study focuses on the geochemical features of precipitates from a Dispersed Alkaline Substrate passive remediation system located at the Esperanza mine, as a first step in assessing the valorization potential. The geochemical profile of the precipitates was analyzed using X-ray diffraction, scanning electron microscope and inductively coupled plasma techniques. The findings reveal preferential fronts of precipitation and the concentration of elements, including Fe, Al, Cu, Zn, and rare earth elements across the profile. These fronts correspond to the dissolution of the alkaline reagent, calcite, and the consequent precipitation of sulfate mineral phases. Correlation analyses showed patterns of co-precipitation among elements, especially concerning fronts of Fe oxyhydroxysulfates, basaluminite, and the varying behaviour of Zn and Rare earth elements. The economic assessment revealed significant concentrations of economically valuable elements within specific depth intervals (i.e. Al: 4.3 tons, Zn: 670 kg, Cu: 370 kg, REE: 35 kg, Co: 16 kg , Y: 1 kg, or Sc: 0.6 kg), indicating areas with substantial potential for element recovery.

Following the principle of common but differentiated responsibilities, we propose Foreign–Investment–Contribution-Based Accounting (FICBA) to delineate national responsibilities. Unlike Production-Based Accounting (PBA) and Consumption-Based Accounting (CBA), which represent extremes, FICBA rewards foreign investment's economic contribution in host countries by sharing the Balance of Emissions Embodied in Trade (BEET, redistributed as BEET+ and BEET−). Additionally, using Structural Decomposition Analysis (SDA), we categorize industries and identify the influence of three key factors—technological levels, industrial structures, and trade scales—on air pollution emission changes over the past twenty years.Under FICBA, countries with negative total BEET values, like China and India, bear lower pollution emission responsibility than PBA but higher responsibility than CBA, reflecting the redistribution of additional emissions based on economic contribution. Conversely, countries with positive total BEET values, like the United States and Japan, experience the opposite. This indicates FICBA can incentivize industrial countries to assume greater responsibility than emerging economies. Consequently, we argue FICBA is an efficient policy promoting global pollution reduction, curbing health damage, and fostering economic development. Moreover, FICBA's responsibility differences with CBA are significantly smaller than those with PBA. According to SDA results, for countries with negative total BEET, enhancing the secondary industry's technological level and restructuring the industry can reduce air pollutants embodied in trade, benefiting development and modernization.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"28 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
