A mixed-integer linear programming model is proposed to determine the optimal configuration of collection stations, assignment of waste generation points, installation of smart monitoring systems, and allocation of waste flows to treatment and recycling facilities within a multi-echelon municipal logistics network. The model minimizes total system cost while satisfying capacity, budget, and recycling constraints. A numerical experiment based on a representative case study of Tabuk city, Saudi Arabia, is conducted to demonstrate the applicability of the model. The results show that the optimal network opens three collection stations and allocates waste efficiently across treatment facilities, achieving a diversion rate of approximately 72% from landfill. The comparative and sensitivity analyses indicate that integrating source segregation with monitoring-enabled operational coordination, optimized infrastructure utilization, and resource recovery can significantly improve economic performance while reducing landfill dependency. Sensitivity analysis reveals that segregation participation, recycling revenue, and disposal cost are key drivers of system performance. Increased participation in source segregation leads to higher recovery rates and improved economic outcomes, while higher recycling revenues and disposal costs promote waste diversion from landfill. The findings highlight the importance of coordinated planning, economic incentives, operational coordination, and public participation in developing sustainable waste management systems.

However, hydro–wind–solar–pumped storage complementary systems for ultra-high-voltage direct current power delivery still face two key challenges. The first is the difficulty of formulating stable transmission profiles. The second is the mismatch between generation-side capacity and grid-side transmission capacity. To address these challenges, this study develops a source–grid coordinated optimization framework with transmission corridor capacity treated as a rigid engineering constraint. Photovoltaic installed capacity and transmission corridor capacity are defined as the core decision variables. A multi-timescale dual-layer dispatch model is incorporated into the proposed framework. The CRITIC–GLDS multicriteria decision-making method is further integrated to identify the economically optimal scheme within the technical feasibility domain. A clean energy base in the upper reaches of the Yellow River, comprising 2320 MW of hydropower capacity and 4200 MW of pumped storage capacity, is selected as the case study. The results show that stable transmission profiles can be generated under a 95% export plan fulfillment rate constraint. The economically optimal matching relationship between transmission corridor capacity and photovoltaic installed capacity is approximately 1:2.5. The preferred configuration is identified as 18 GW photovoltaic capacity and 8 GW transmission corridor capacity. Under this configuration, the levelized cost of electricity is 256.62 RMB/MWh, the transmission corridor utilization rate is 61.78%, and the renewable energy utilization rate is 91.11%.

In this study, a data-driven multi-period EVB recycling network design problem is investigated from a fourth-party logistics (4PL) perspective. The contributions involve two main aspects. First, an advanced data-driven optimization framework is proposed, wherein forecasting methods are evaluated based on the quality of the resulting decisions, thereby establishing a closed-loop linkage between prediction and optimization. Second, the 4PL concept is integrated into EVB recycling network design by jointly optimizing site selection and transportation link selection, facilitating the effective coordination of multiple third-party logistics providers, whereby network flexibility and operational efficiency are enhanced. To solve this problem, a two-stage stochastic multi-period network design model is formulated, and subsequently reformulated as a mixed-integer linear programming model using sample average approximation. To ensure computational scalability, a scenario decomposition and relaxation-based heuristic algorithm is developed, which integrates Latin hypercube sampling, Lagrangian relaxation, and the progressive hedging algorithm. Finally, numerical experiments using realistic profiles are conducted to validate the effectiveness of the proposed model and algorithm. Numerical results demonstrate that the Transformer-based design achieves the lowest decision regret, with only 0.03% regret relative to the actual-demand benchmark. Compared with the GRU-based design, which performs strongly at the forecasting layer but yields 1.28% decision regret, the Transformer-based design reduces regret by approximately 97.3% and lowers the realized cost by about USD 0.62 million. These findings indicate that evaluating forecasting methods through downstream optimization outcomes can help mitigate the suboptimality caused by relying on statistical accuracy alone. Furthermore, the extended low-carbon analysis shows that carbon regulations significantly reshape the EVB recycling network. A moderate carbon tax (0.08–0.10 USD/kg) increases green 3PL adoption from 46.22% to over 53% while reducing variable emissions per EVB by approximately 1.4%, while RCR decreases only from 75.39% to 74.23%. In contrast, stringent carbon caps reduce variable emissions per EVB by about 4.4% but substantially decrease the recovery rate from 75.39% to 58.93%, highlighting a critical trade-off between decarbonization and circularity.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"574 ","pages":"Article 149022"},"PeriodicalIF":10.7,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148692960","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}

In this study, we systematically investigated the spatiotemporal evolutionary dynamics of HMs and PAPs emissions, as well as their synergistic effects, using an established long-time-series HMs and PAPs emission inventory based on a facility-level point source activity database.

In this context, the use of aqueous epoxy emulsified asphalt is regarded as an effective maintenance solution. However, its large-scale application still faces practical challenges, particularly regarding the carbon footprint associated with petroleum dependence and the fluctuating economic costs of synthetic raw materials. As a renewable resource with abundant reserves and excellent affinity with asphalt, lignin provides a strategic opportunity to break this deadlock. This study developed a “green preparation method for lignin-based aqueous epoxy emulsified asphalt.” Lignin-based aqueous epoxy resin was synthesized through simple chemical grafting of lignin with glycerol triglycidyl ether (GTE). Furthermore, the thermodynamic spontaneity and chemical bonding process of the grafting reaction were demonstrated at the molecular level using electrostatic potential (ESP) calculations and FTIR spectroscopy. Performance evaluations indicate that the construction of a three-dimensional cross-linking network within the system, when the lignin-based aqueous epoxy content reaches 12 wt%, is the physical essence behind the enhancement of macro-performance. Moreover, rheological and interfacial thermodynamic analyses confirmed that this network significantly reinforces the high-temperature rheological properties and adhesion performance of the system. At the mixture level, performance tests including high-temperature rutting, low-temperature bending, and moisture stability confirmed that the proposed material maintains robust high-temperature stability while balancing low-temperature crack resistance and resistance to hydrothermal damage. Furthermore, a simplified life cycle assessment (LCA) indicates that the incorporation of lignin-based aqueous epoxy provides a potential reduction of approximately 10% in global warming potential compared to conventional bisphenol A-based systems.

This study develops a durability-informed comparative framework that links anisotropic chloride transport to maintenance-normalised carbon implications in 3DP-UHPC. Long-term immersion experiments were conducted to obtain depth-resolved chloride profiles for different build orientations. A time-dependent diffusion model incorporating surface chloride accumulation kinetics was used to identify orientation-dependent transport parameters, which were subsequently translated into corrosion-initiation-based service life and a parameterised carbon amplification formulation over a 50-year design horizon. Results show that corrosion initiation under a 20 mm cover condition is governed primarily by surface accumulation kinetics rather than instantaneous diffusion intensity. A stable durability hierarchy (3D-Z &gt; MC ≈ 3D-Y &gt; 3D-X) persists under realistic variations in corrosion threshold and cover depth. Within the adopted comparative framework, and using 3D-X as the reference condition, orientation optimisation yields up to a 38% relative reduction in the parameterised annualised carbon-intensity indicator without altering material composition or structural geometry.

This uneven adoption reflected not individual motivation but how far institutional, logistical, relational, and economic conditions aligned, and varied with producers' scale, sector, and market position. As such, circularity in regional agrifood systems is framed as a challenge of ecosystem-level governance rather than -organisational level innovation.

It is therefore essential to employ proper market trading frameworks to guarantee the economic efficiency of prosumers while preserving privacy and improving operational autonomy. Motivated by these challenges, this paper develops a multi-stage prosumer-community-centered scheduling and trading framework for energy management and transactive energy objectives. To address prosumer-centered objectives, a multi-agent twin-delayed deep deterministic policy gradient (MATD3) algorithm is employed for scheduling prosumers' demand load, energy storage system (ESS) operation, and bid/ask prices under the decentralized training and execution (DTDE) strategy. Additionally, a flexibility-in-trading (FinT) concept is introduced for optimal peer-to-peer (P2P) market participation, evaluated by fuzzy satisfaction level-based (FSL) sensitivity analysis. At the community level, a centralized community-to-community (C2C) market is implemented to facilitate communities' net load exchanges and coordinate dual market clearing between prosumers and communities. A case study of 90 residential prosumers, divided into six energy communities, is engaged in P2P and C2C transactions consisting of real-world data. Finally, market transactions are recorded in an Ethereum-based consortium blockchain to ensure transparency and cyber-physical security. Quantitative results with scheduling errors below 10% and 12.6% in the scheduling and trading stages represent stable learning. Moreover, the proposed FinT mechanism achieves Jain's Fairness Index of 0.88 and FSL mean-score of 92.6%, illustrating effective and equitable market participation. The findings confirm that the proposed system improves operational flexibility and transaction transparency and provides a pathway toward cleaner and sustainable prosumer-centric energy communities.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"574 ","pages":"Article 149041"},"PeriodicalIF":10.7,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148693043","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}
