Integrated stove is an emerging side suction fume exhaust device with an exhaust outlet closer to the emission source. In capturing fumes, the integrated stove is a great improvement over the previous top suction fume exhaust device. For further optimizing the control effect of integrated stove on fumes and reducing the pollution of kitchen environment by cooking, this study proposed a new kitchen ventilation approach with integrated stove air supply and fume exhaust (ISASFE). Its performance of capturing fine particulate matter (PM2.5), a typical pollutant in fumes, and its energy-saving effects were investigated. Employing a blend of orthogonal design and CFD simulations, five key factors affecting its operational effectiveness were analyzed deeply. The fume exhaust effectiveness of ISASFE was assessed utilizing capture efficiency. The energy-saving effect of ISASFE under different emission rates was analyzed by using polynomial fitting and actual measurement methods. Results demonstrate downward air supply speed and exhaust rate as the most crucial factors, with upward air supply speed, downward air angle, and emission rate following in importance. Compared to the conventional stove without air supply, ISASFE exhibited enhanced capture efficiency by 1.8% at low, 13.9% at medium, and 14.5% at high emission rates, respectively. The energy saving rate of ISASFE was 23%-42%. The new ventilation strategy proposed in this study not only enhanced the PM2.5 capture efficiency of the side suction integrated stove, but also helped to reduce the kitchen ventilation energy consumption.","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"4295-4308"},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143990780","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}

High value-added products can be obtained by direct casting. Life cycle assessment (LCA) is used to evaluate the environmental performance of the newly developed system compared with the traditional Al recycling technology. Results have shown that the low-cost small-scale Al recycling technology performs better in environmental categories such as climate change, ozone depletion and eutrophication, while the traditional recycling method shows advantage in acidification, eutrophication (terrestrial), and eutrophication (marine). This low cost small-scale Al recycling system is easy to duplicate and to operate.

In this study, the interaction process of polyhydroxyalkanoates microplastics (PHA-MPs) with tetracycline (TC) under persulfate-based oxidation systems was investigated. Characterization results indicated that persulfate oxidation process not only changed the surface morphology of PHA-MPs, but also produced many oxygen-containing functional groups. Meanwhile, through the application of 2D-COS analysis, the oxidation sequence of functional groups in PHA-MPs was clearly identified. The adsorption capacity of PHA-MPs was maximized at pH = 7, and high salinity inhibited the adsorption capacity, while the addition of Co(II), Ni(II), and Cu(II) could significantly promote the adsorption capacity. In addition, the adsorption kinetics fitted well with the pseudo-second-order kinetic model, and the adsorption isothermal process followed the Freundlich model, which was belonging to multi-layer adsorption. The above results were helpful to further assess the risks associated with the combined pollution of biodegradable MPs and organic pollutants.","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"4383-4393"},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144126979","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}

However, it remains a significant challenge to optimise the rubber content between its mechanical strength and durability under freeze-thaw conditions. In this study, the macroscopic mechanical properties of ordinary cement soil and rubber-cement soil (with particle sizes of 30 and 60 mesh) were explored under different freeze-thaw cycles (0, 3, 6, 9, 15) by taking the wave propagation and unconfined compressive strength (UCS) tests. Subsequently, a series of scanning electron microscope (SEM) and X-ray diffraction (XRD) tests were conducted to analyse the microstructure of the specimens, further clarifying the freeze-thaw damage mechanisms in rubber-cement soil. The results show that freeze-thaw cycles cause irreversible internal damage to the cement soil, leading to continuous reductions in both wave velocity and UCS. After 15 freeze-thaw cycles, the wave velocity loss rates are 95%, 72.2%, and 89.7% for ordinary cement soil, cement soil mixed with 30-mesh and 60-mesh rubber particles, respectively. The corresponding UCS loss rates are 95.4%, 82.7%, and 89.2%, respectively. The above results suggest that 30-mesh rubber-cement soil exhibits superior frost resistance. From a microstructural perspective, the rubber particles delay and inhibit the propagation of frost heaving cracks, forming a denser spatial structure for calcium silicate hydrates (C-S-H) gel, thereby improving the freeze-thaw resistance. By integrating macroscopic mechanical testing and microstructural analysis, this study reveals the mechanical properties and damage mechanism of rubber-cement soil under freeze-thaw conditions, providing valuable insights for its engineering applications.","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"4394-4406"},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144093108","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}

After data cleaning, principal component analysis (PCA) was used to eliminate correlations among input variables and GA was applied to optimize the hyperparameters of the LSTM model which was compiled with the Adam optimizer. Lastly, a NOx emission trend prediction model with practical engineering value was proposed, specifically considering the co-incineration of sludge and waste.
