Herein, adhering to the concept of \"total solid waste utilization\", phosphorus tailings based artificial lightweight aggregates (PT-LWA) were fabricated through multi-component collaborative design, using phosphorus tailings (PT), fly ash (FA), soda residue (SR), and granulated blast furnace slag (GGBS) as the 100 % raw material system. A comprehensive analysis was conducted to assess how varying proportions of raw materials and diverse curing conditions influence physical performance, microstructural features, durability, release characteristics of heavy metals. Additionally, economic costs and economic emissions from PT-LWA were analyzed. The findings showed that the artificial lightweight aggregates exhibited optimal efficiency when fabricated with a raw material ratio of PT: FA: SR: GGBS = 40 %:20 %:30 %:10 % under 80 °C steam curing conditions. Specifically, the bulk density, softening coefficient, and 1-h water absorption of the resultant PT-LWA were 1038 kg/m³, 0.942, and 14.1 %, respectively. Additionally, the cylinder crush strength attained a value of 9.7 MPa, surpassing the performance observed in conventionally cured samples. Microstructural analysis revealed that the dominant hydration phases primarily consisted of C-(A)-S-H gel formations. They are evenly distributed on particle surfaces and form a robust colloidal structure, which further enhances its strength. The concentration values of released heavy metals are well below the thresholds defined by China's hazardous waste identification standards (GB 5085.3-2007), suggesting that PT-LWA will not cause secondary environmental pollution.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"527 ","pages":"Article 146693"},"PeriodicalIF":10.0,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145227730","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}

By using Patch-generating Land Use Simulation and benefit transfer methods, an assessment baseline for the scenario without ERP was established, and the effectiveness of ecosystem service value (ESV) for different restoration types was evaluated. Redundancy analysis and Partial Least Squares Structural Equation Modeling were then employed to decouple the direct and indirect effects of environmental variables on the ESV effectiveness. The main findings indicate that climate, terrain, and human activity intensity were the primary environmental factors influencing the ESV effectiveness. In damaged areas with rich hydrothermal conditions, complex terrain, and strong human activity interference, the direct improvements in ESV after restoration were more obvious. However, the environmental constraints on the recovery of vegetation and water body were also greater, which indirectly weakens the ESV effectiveness.

This breakthrough addresses long-standing challenges in humic acid production, particularly in terms of efficiency and energy consumption. Multi-scale characterization techniques, including FTIR and TG, revealed unique structural features of the products: compared to standard humic acid, the humic acid and humin derived from oxidative pyrolysis exhibit a higher proportion of lightweight components (e.g., carboxylic acids, polysaccharides, and phenols), lower aromaticity, and reduced molecular weight. These characteristics, characterized by low polymerization and high bioactivity, significantly enhance their potential for agricultural applications. A life cycle assessment (LCA) further quantified the environmental benefits of this technology, demonstrating a reduction of 12,700 tons of CO₂-equivalent emissions per 10,000 tons of humic acid produced, alongside a waste resource utilization rate of approximately 75 %.

This study presents a novel machine learning–enhanced uncertainty quantification (ML-UQ) framework that, for the first time, integrates a high-fidelity surrogate model—an artificial neural network with autoregressive feedback—into Aspen Plus simulations of a hybrid ammonia production system coupled with a vapour absorption refrigeration unit for heat recovery. The framework captures nonlinear interactions among six critical uncertain parameters, including renewable power variability, heat exchanger effectiveness, and compressor efficiency. It reduces the computational cost by three orders of magnitude while maintaining high predictive accuracy (R² = 0.97, MAE = 8.57, RMSE = 11.3). The ANN surrogate enables scalable uncertainty propagation via polynomial chaos expansion. Results show that, across nominal power levels of 10–20 MW, uncertainties can cause up to 18 % variation in ammonia output, 30 % in refrigeration, and 40–50 % in CO₂ emissions reduction.
