This study utilizes ArcGIS to visualize the spatial migration patterns of carbon emissions across China as a whole, specifically focusing on the industry and construction sectors. The spatial distribution is illustrated using standard deviation ellipses. Employing panel data encompassing 26 Chinese regions from 1992 to 2021, we empirically examine the impact of carbon trading policies on emissions in the industry and construction sectors within Hubei Province, employing the synthetic control method. Our findings underscore several key points: (1) Between 1992 and 2021, the center of carbon emissions in China initially shifted towards the southwest before transitioning to the northwest, indicating a shift from a northeast-southwest distribution to a northwest-southeast distribution. The center of carbon emissions within the industry and construction sectors exhibited a comparable southwest shift, indicating a shift from a distribution pattern oriented towards the northeast-southwest direction to one favoring a northwest-southeast pattern. (2) The correlation between carbon emissions and economic progress within the industry and construction sectors in China fluctuated predominantly between states of strong and weak decoupling, with a growing number of provinces successfully achieving this decoupling. As of 2021, every province showcased a decoupling scenario wherein carbon emissions and economic development within these sectors were detached. (3) The implementation of carbon trading mechanisms played a significant role in effectively curbing carbon emissions within Hubei's industry and construction sectors.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 15","pages":"15339 - 15354"},"PeriodicalIF":3.4,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145204680","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}

This study proposed a bin model using <i>Perionyx excavatus</i> worms to both treat household organic waste and grow vegetables for household consumption. Different aeration modes for bin model and different plants, <i>Sauropus androgynus</i> and <i>Chili Pepper,</i> were tried. The results showed that the bin could operate better with the addition of a ventilation pipe. It could handle organic waste up to 111 days with an average of 0.43 ± 0.17 kg/day. The total domestic organic waste added to the bin was 45.94 kg, in which the percentage of decomposed organic waste was 90.62%. Products obtained from the studied household-scale vermicomposting bin include vermicast (5.9 kg), the biomass of <i>P. excavatus</i> (150 g) and the biomass of plants (1.1 kg). The model didn’t generate odors, leachate or attract harmful insects owing to the planting integration. With the amount of input organic waste rate of about 0.43 ± 0.17 kg/day, the recommended time for vermicast harvesting was 1.5 months to keep the bin core from being full. In addition, the <i>S.

One promising approach for OCS treatment is stabilization/solidification using alkali-activated materials (AAMs), which are recognized as an environmentally sustainable alternative to cement and lime. Despite extensive research on AAM applications, the compressibility behavior of OCS stabilized with AAMs remains largely unexplored. This study aims to address this gap by investigating the effectiveness of alkali activation of granulated blast furnace slag (GBFS) in mitigating the compressibility of OCS while simultaneously contributing to slag waste reduction, and cost-effectiveness. A comprehensive experimental program was conducted, incorporating pH, electrical conductivity (EC), cation exchange capacity (CEC), organic matter content, unconfined compressive strength (UCS) tests, ultrasonic pulse velocity (UPV) measurements, one-dimensional consolidation tests, and microstructural analyses. The findings demonstrated that alkali-activated slag (AAS) effectively stabilized and solidified OCS by inducing the formation of cementitious phases. This treatment resulted in a minimum 180% increase in UCS, a reduction in compressibility by at least 40%, and a decrease in the permeability coefficient by over 90%. Moreover, replacing 8% cement with the alkaline activation of 15% slag led to a 55% reduction in CO<sub>2</sub> emissions, while also lowering energy consumption and cost by 52% and 46%, respectively, to achieve a compressive strength of 1 MPa. Additionally, the study underscored the critical role of calcium content in enhancing the mechanical properties of AAS-stabilized OCS. In conclusion, AAS improves OCS geotechnical properties, making it a sustainable and viable material for construction and infrastructure development.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 13","pages":"12363 - 12384"},"PeriodicalIF":3.4,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144814306","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}

The experimental study using ultraviolet irradiation and titanium dioxide catalyst revealed that maximum degradation of 94% was reached at optimum conditions with an irradiation time of 420 min, a chlortoluron concentration of 10 mg L<sup>−1</sup>, a recirculating flowrate of 91.1 mL min<sup>−1</sup>, a distance between the lamp and reactor of 8 cm, and a free pH of 6.5.

The performance metrics showed that both models were capable of producing accurate predictions, with the neural network results being slightly superior. To search the optimal values of the degradation process parameters, the neural networks was selected as objective function for the genetic algorithm. Among the thirty-five Pareto solutions, one optimal solution is selected using the Technique for Order Preference of Similarity to Ideal Solution and the recommended values of the objective functions are 94% for removal efficiency and 588 KWh m<sup>−3</sup> order<sup>−1</sup> for energy.
