To improve the water retention capacity of miscanthus fibre mortar, the effects of superabsorbent polymer (SAP) content (0.1 wt.%, 0.2 wt.% and 0.3 wt.%) on the physical characteristics, mechanical strength, microstructure, plant growth performance, drought resistance and the mortar properties after planting are investigated in this study. The results show that the addition of low SAP content (0.1% and 0.2%) enhances the water retention capacity, which can absorb 67-71% of water by its weight at 0.5 h and then retain 21-27% of absorbed water until 11 days. The SAP has a significant effect on the early germination and rooting of plant seeds. The plants grow well on the mortars SAP0.2% and SAP0.3% surface after germination, showing a more number of plants, compared to the mortar Ref. Moreover, as the SAP content increases, the plant cover percentage shows a gradually increasing trend. However, a high plant cover percentage exhibits a negative impact on plant height, leaves and root development for the individual plant. In addition, plant roots are prone to grow laterally, and plant roots can penetrate deeply into the mortar matrix. The increased water absorption of the miscanthus fibre mortar is an effective method to improve plants` resistance to drought climatic conditions. The use of 0.2% SAP is preferred for improving plant growth adaptability in sustainable greening projects, considering good water retention ability and without sacrificing its strength.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"11 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825738","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}

How to effectively prevent and control forest fires has become a top priority. However, water-based fire extinguishing agents commonly used in forest fires possessed the problems of poor spraying effectiveness, adhesion and spreading, and fire extinguishing efficiency. Inspired by the porous thermal insulation materials, a novel silica hydrogel-based fire extinguishing agent (SiKP) was successfully prepared by micro-crosslinking silica aerogel and introducing phosphorus and potassium fire extinguishing elements. SiKP showed excellent high-temperature adhesion properties on wood surfaces and their pH meets the requirements of its application. After spraying SiKP, the open flame of the wood stacks was extinguished quickly within 2 s and the smoldering time of wood stacks was 29.71% less than that of pure water. The phosphorus- and potassium-containing free radicals and inert gases from the decomposition of SiKP effectively interrupted the free radical chain reaction and diluted the combustible gas concentration in gas phase. Besides, SiKP promoted the dehydration and charring of forest vegetation and the formation of a compact barrier char layer effectively prevents the transfer of heat and flammable volatiles in condensed phase. Consequently, the total heat and total smoke release of NW/Si3K3P6 were decreased by 51.05% and 72.86% compared with pure pine. This novel forest fire extinguishing agent with excellent adhesion, fire extinguishing, and sustained fire resistance properties shows great value for the prevention and control of forest fires.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"16 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825735","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}

This study compares the energy, economic, and environmental benefits of five potential methanol-to-power (M2P) routes: direct methanol power generation and four electrochemical/thermochemical power generation routes coupled with the methanol pretreatment process. Energy conversion and distribution for each M2P process are analyzed, focusing on key technical and economic indicators, and competitive targets are established to promote the market adoption of M2P pathways. The results indicate that none of the potential M2P routes are competitive under current technical and economic conditions, with energy efficiency ranging from 16.65% to 44.28%, underscoring the need for further research and development. A projected 40% reduction in methanol costs may render routes utilizing MSR and ATRM fuel pretreatment technologies economically beneficial, with the levelized cost of electricity for all pathways aligning with the current renewable energy generation costs. Life cycle analysis exposes that carbon emissions from methanol utilization are more significant than those stages, while the combining of the latter three M2P pathways with emerging renewable methanol synthesis technologies minimizes environmental impact. Despite the uncertainties and economic risks associated with methanol-to-electricity conversion, exploration of potential application scenarios of various pathways establishes a foundation for future advancements.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"51 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832433","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}

Since the wastewater treatment process (WWTP) is a time-varying and highly complex system, it is challenging to design an effective optimization control method to ensure effluent quality (EQ) and reduce energy consumption (EC). To overcome this problem, a dynamically multi-objective optimal control strategy is proposed in this paper. Firstly, a multi-objective gray wolves optimization algorithm based on subpopulation and multi-strategy exploration (MOGWO-SM) is designed to obtain dynamic setpoints that can achieve the tradeoff between EC and EQ. Then, multi-unit nonsingular fast terminal sliding mode controllers based on extended state observer (MNFTSMC-ESO) are used to accurately track these setpoints to keep the dissolved oxygen and nitrate maintained at appropriate concentrations throughout the WWTP. Finally, the effectiveness of the proposed method is verified using the Benchmark Simulation Model No. 1 (BSM1). Simulation results show that the proposed method not only has satisfactory control accuracy, but also can ensure that the effluent quality meets the discharge requirements with a significant reduction in EC. EC values are decreased by 10.14% and 21.69% compared with traditional PID strategy in dry and storm conditions, respectively. Overall, the proposed method has a certain potential for practical application due to its superior performance, contributing to sustainable wastewater management.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"63 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825593","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}

They serve as an effective alternative to Ordinary Portland Cement (OPC) for semi-flexible pavement (SFP) grouting applications. This study first involved the mix design of open-graded asphalt (OGA) mixtures and geopolymers, including the original geopolymer (OG) and modified geopolymer (MG). Furthermore, the SFP mixtures infused with two types of geopolymers were cured, and the road and mechanical performance were evaluated at the specified time intervals (7 days, 14 days, and 28 days). Finally, the failure mode of SFP mixtures and the adhesion characteristics of OG and MG with asphalt were examined comprehensively by macroscopic test (low-temperature bending beam test), mesoscopic test (pull-out test), and microscopic tests (contact angle and infrared spectroscopy tests). The results indicate that, in comparison to OG, the SFP mixtures utilizing MG as the grouting agent exhibit superior performance at each stage of the curing cycle. The geopolymer-asphalt interface remains the vulnerable junction in SFP mixtures. MG shows improved bonding strength with asphalt throughout a range of curing ages and greater adsorption ability with asphalt. During the entire life cycle (LC), SFP-MG can reduce the number of maintenance times, resulting in high sustainability.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"253 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825737","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}

Firstly, the chemistry and modification mechanism of PPA were discussed. Subsequently, the properties of PPA composite modified asphalt and its mixture were comprehensively evaluated. Moreover, composite modifications of PPA with other modifiers such as crumb rubber and polyethylene (PE) were reviewed, which presented satisfying performance and environment advantage. Long term performance evaluation, environmental assessment and economic analysis were also discussed. Various microscopic techniques could confirm the improvement of high temperature performance, which stands out as its most exceptional property. Besides, PPA composite modified asphalt processed excellent anti-aging property and storage stability, but the poor low temperature property and undesirable adhesion property were potential defects that restricted its application. PPA composite modified asphalt mixture presented analogous properties to the corresponding asphalt. Notably, low temperature performance of asphalt mixture was questionable due to inconsistent results from different test.

The results showed that: (1) Carbon supply is higher in the western inland and lower on the eastern coast, while carbon demand expands from the east to the west. (2) From 2000 to 2020, a noticeable spatial mismatch between carbon supply and demand. Areas with a carbon surplus reduced from 99.4% to 96.0%, whereas carbon-deficient areas increased from 0.6% to 4.0%.
