Experimental evaluations were performed at a fixed engine speed of 1500 rpm under varying load conditions (0%–100%), with C2H2 introduced into the intake at flow rates of 3 and 6 liters per minute (LPM). The selection of C2H2 was predicated on its substantial energy density (48.22 MJ/kg) and rapid flame propagation, which facilitated improved combustion characteristics. The findings revealed that brake thermal efficiency increased by 27.32% at 3 LPM and 44.76% at 6 LPM compared to diesel fuel. Emissions of carbon dioxide, carbon monoxide, and hydrocarbons were diminished by 26.49%, 71.32%, and 34.66%, respectively, signifying a cleaner combustion process. However, nitrogen oxide emissions escalated by as much as 55.98%, underscoring the necessity for the implementation of emission control measures. In summary, this investigation demonstrates that integrating C2H2 with CSOB can enhance engine performance while simultaneously reducing detrimental pollutants. This dual-fuel approach presents a feasible and economically viable alternative for agricultural and off-grid energy applications, necessitating only minimal adaptations to conventional diesel engine configurations.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148076573","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}

Their performance is optimized through strategies targeting the Fe3+/Fe2+ cycle, including: (i) composition and defect regulation (e.g., doping/heterojunctions and oxygen-vacancy engineering), (ii) morphological control of iron oxides, zero-valent iron, and Fe-MOFs, (iii) substrate design using one-, two-, and three-dimensional supports, and (iv) spatial confinement in 1D/2D/3D architectures. This review summarizes recent advances in these structural regulation strategies for INPs, focusing on catalytic activity, stability, and reusability. The modulation of local electronic structures, adsorption/transport, and oxidant activation to enhance these properties is discussed. For comparative analysis, we report a single benchmark—the apparent initial molar volumetric rate (r0,molar = kobs × C0,molar)—along with literature removal data. Practical considerations, including Fe-site regeneration, Fe-leaching control, and long-term operation, are also addressed to contextualize the deployment of INP-based catalysts. Future research should focus on achieving durable Fe-valence cycling, improving H2O2 utilization, and developing scalable, low-cost synthesis methods to advance the application of INPs in water pollution control.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148085850","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, realising these benefits depends on addressing significant technical, economic, and systemic barriers. AI technologies, such as intelligent waste-sorting systems and predictive models, are transforming how waste is processed and materials are reused. This article critically evaluates the potential and limitations of AI-driven approaches across the waste management lifecycle through a narrative review of peer-reviewed literature published between 2015 and 2025. AI offers a revolutionary approach to waste management, resource recovery, and environmental impact reduction by enabling the processing of massive datasets and automating complex decision-making. However, to fully realize AI's promise, critical issues, including scarce data availability, expensive implementation costs, the requirement for efficient human-AI cooperation, and ethical considerations regarding algorithmic transparency and workforce impacts, must be systematically addressed. Additionally, ethical concerns related to job displacement and the environmental footprint of AI technologies themselves require careful management. This review identifies significant research gaps, including the need for standardized datasets, explainable AI frameworks, and comprehensive lifecycle assessments of AI-driven interventions. Looking to the future, decentralized AI systems, AI-driven global waste trade optimization, blockchain-integrated tracking systems, and AI-enhanced product design offer promising avenues for further innovation. As AI continues to develop, its incorporation into waste management systems will be essential to accelerating the world's shift to a circular economy that is more resource-efficient and sustainable.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ep.70322","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148076770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A rainfall model assessed water seepage in the capillary barrier landfill cover system. The water-holding capacity of the CBM was found to be equivalent to that of silty clay, and the hydraulic conductivity was 2.06 × 10−6–1.41 × 10− 4cm/s. No rain leakage occurred at the bottom of the capillary barrier cover system during a rainstorm and heavy rainstorm. This was mainly attributed to the covering material storing rainwater in the pores via the capillary block effect, and the stored water then dissipating through evaporation. This study provides data support for the design and popularization of a capillary barrier landfill cover system in the middle reaches of the Yangtze River. However, the material ratio of the capillary barrier layer should be adjusted according to the source of construction waste and municipal dehydrated sludge.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148076574","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}

Recent advances in nanotechnology have demonstrated that incorporating nanoparticles can overcome these drawbacks by improving the thermochemical behavior of biodiesel blends. Studies have reported that adding 50 to 100 ppm of metal-oxide or carbon-based nanoparticles can increase brake thermal efficiency by 4% to 9%, reduce brake-specific fuel consumption by up to 8%, and lower CO and NOx emissions by 20% to 35%. This review provides a comprehensive synthesis of the mechanisms governing nanoparticle-fuel interactions, including catalytic oxidation, micro-explosion phenomena, and enhanced thermal conductivity, which collectively promote complete combustion and improved energy conversion. Furthermore, it analyzes comparative data on nanoparticle type, synthesis route, dosage, and performance outcomes to establish structure–function relationships. Distinct from previous reviews, this article integrates three critical dimensions like thermochemical mechanisms, performance optimization, and ecotoxicological impact, offering a holistic understanding of nanotechnology enabled biodiesel systems. The review also addresses environmental and health concerns related to nanoparticle dispersion, stability, and post-combustion residues, emphasizing the need for safer nanomaterial design and lifecycle evaluation. By linking mechanistic insights with analytical evidence, this state-of-the-art review aims to guide both research and industrial implementation toward the development of efficient, low-emission, and environmentally responsible biodiesel formulations aligned with global sustainability goals.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148084396","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}

Herein, modified corn straw biochar (LBC)/sodium alginate (SA) composite (LBS) adsorbents were prepared to eradicate phosphate from water (belonging to batch adsorption). The results showed that the best pyrolysis temperature for preparing LBS was 550°C, and the specific surface area and average pore diameter of the 550LBS (LBS at 550°C) 80.96 m2/g and 3.82 nm, respectively, indicating more adsorbability. The maximum adsorption amount was 61.4 mg/g (exceeding 36.44 mg/g) when pH was 2 and the mass ratio of 550LBC/SA was 0.3 g/0.3 g. The adsorption of phosphate by 550LBS was consistent with the Langmuir model and the pseudo-first-order model (R2 > 0.95) and reached adsorption equilibrium at 20 min. The adsorption of 550LBS was due to the protonation between the surface hydroxyl group and H+, and the phosphate adsorption of 550LBS was dominated by ligand exchange and electrostatic attraction. Compared with the maximum adsorption capacity of 550LBS, the used 550LBS could be reused; the adsorption efficiency of adsorbents after three tests was still above 41% using deionized water as the desorption agent, showing good reusability and renewability of 550LBS and low-cost adsorbents. It possessed suitable scientific results for researchers in the field of environmental sciences. The study presented a low-cost, sustainable adsorbent for phosphate removal, addressing eutrophication and water pollution concerns.
