In particular, the system layout of the considered CAES includes: a compression train, an expansion train and a compressed air tank. All these components are modelled in MATLAB by suitable algorithms. The developed CAES is also coupled with a renewable plant supplying electricity to a plurality of users. The overall simulation model of the renewable plant, including the CAES, is developed in TRNSYS. The compressions train includes two centrifugal compressors and one reciprocating compressor. The expansion train includes three radial turbines. This model is designed for assessing the time dependent performance of the compressed air energy storage tracking the excess electricity in charging phase and the load in discharging phase. The models of the compressors and turbines are developed using the manufacturer maps approach. The selected user is a residential user including 50 buildings located in Naples, South of Italy. The proposed renewable plant consists of a compression train, featured by an overall capacity of 3.5 MW, a 1.5 MW expansion train and a 250 m³ compressed air tank at 350 bar. This system is integrated with a 6.30 MW photovoltaic field and 2000 m² solar field of evacuated collectors. The photovoltaic electricity firstly meets the demand of the district users. The excess renewable electricity is used to drive the compressed air energy storage system. This system also includes a suitable waste heat management system, designed for storing the waste heat due to compression and reducing the air temperature at the inlet of each compressor. Such waste heat is used for heating the air delivered to the turbines. The thermal energy provided by the evacuated collector solar field is used for increasing the turbines inlet temperature.</div><div>The proposed system achieves promising energy results, being able to reduce by 59 % the primary energy demand of the selected residential district.

Researching the plastic kinetic properties of both pyrolysis and hydrothermal process is necessary to verify the mechanism and promote efficient utilization of plastic. In this work, thermal analysis kinetics of polyoxymethylene (POM) is employed under different atmosphere and heating rate to research the pyrolysis characteristics. Firstly, model-free iso-conversional methods were performed to study the kinetic performance of pyrolysis. Subsequently, the mechanism function and segmentation analysis method are applied to study the kinetic characteristic and pyrolysis mechanism. Finally, different methods were used to investigate the hydrothermal transformation kinetic performance of POM, and compared with pyrolysis. The result showed that the activity energy of direct pyrolysis calculated by both the model-free method and the C-R method was lower than 100 kJ mol⁻¹ in the initial stage, and in the range of 200–260 kJ mol⁻¹ in the middle and later stages. The most probable mechanism function of direct pyrolysis and hydrothermal reaction was Avrami-Erofeev equation, and the reaction mechanism was random nucleation followed by growth. The activation energy decreased by approximately 30 %, 36 %, and 43 %, respectively, with the vapor content of 25 %, 50 %, and 75 % compared with pyrolysis under dry atmosphere, proving the advantages of hydrothermal conditions from kinetic perspective.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"502 ","pages":"Article 145353"},"PeriodicalIF":9.7,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143672671","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}

We selected 11 industries and calculated their economic development and employment levels respectively, resulting in 22 explanatory variables. At the global scale, there were significant spatial associations between the eleven industries and RLPD by comparing their spatial networks. The impacts of catering industry, accommodation industry, and general equipment manufacturing industry from an economic development perspective on RLPD were negative, while other eleven significant variables were positive. The improvement of the industry level accelerated the clustering of urban population, while high-end catering and accommodation industries were built away from dense crowds. At the local scale, there were variable impacts spatially on RLPD, and the positive impacts gradually increased from the city center outwards in most industries. Better living environments increased people's confidence in residential choices. We further discussed the fine-scale urban land layout by six typical examples and proposed strategies for integrating industry and residence.

To resolve the challenge, it is necessary to address a wide range of ecological, economic, and social concerns for individuals, communities, and policymakers alike. Urban food forestry, as a sub-form of urban agriculture, holds great potential in this regard but remains relatively underexplored. Defined as woody food producing species sited within urban landscapes, urban food forests can provide material and non-material benefits to the environment, societies, and cultures in which they are located. This research article identifies the realised and potential impacts of urban food forests and forestry across three dimensions of urban sustainability: Ecosystem Services, Food Security and Health, and Society and Culture. Differing from agroforestry in which timber products are most sought after, this research has found that urban food forests are highly valued for their ability to provide local foods and medicine, along with their regulating services. Their multifunctionality leads to impacts across the pillars of sustainability, from enhancing biodiversity and conservation, to economic and social inclusivity, human health and wellbeing. Further, analysis has highlighted urban planning and design as a central research theme surrounding urban food forestry. Utilising a systematic approach, this research provides insights into the realised and potential impacts of urban food forests and forestry and identifies drawbacks, concerns, and gaps in the literature, to present a balanced, comprehensive review of this unique form of urban agriculture. This research helps to inform sustainable practices that enhance the resilience of urban communities.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"501 ","pages":"Article 145358"},"PeriodicalIF":9.7,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143666255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

The current understanding of the quantitative impacts of cropland expansion on TWS remains limited. Here, taking the Bogda watershed in the dryland of Northwest China as a case, we examined changes in cropland area, cropland gross primary productivity (GPP), evapotranspiration (ET), and net TWS consumption from 2002 to 2022. Furthermore, we identified the key impact factors of net TWS consumption and predicted its future values for three distinct land development scenarios under climate change. We found that the Bogda watershed experienced a cropland expansion of 522 km², accompanied by increases in total cropland GPP (0.38 million t C), ET (0.87 billion m³), and net TWS consumption (0.86 billion m³). Since 2004, TWS in the watershed has been unsustainable. Further analysis indicated that cropland was the main driver of net TWS consumption, with cropland expansion indirectly increasing net TWS consumption by enhancing ET. Significant positive correlations were found between cropland area and both ET and net TWS consumption. Each additional square meter of cropland increased ET by 1.23 m³ and net TWS consumption by 0.59 m³ on average. Future predictions suggest that TWS may become sustainable if cropland is reduced to 912 km², whereas continued cropland expansion will maintain TWS unsustainability. This study reveals a significant conflict between cropland expansion and water conservation in drylands, and provides critical insights for developing agricultural and water management strategies to support long-term water sustainability.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"501 ","pages":"Article 145333"},"PeriodicalIF":9.7,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143666125","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}

We then interviewed the case municipalities’ property managers and planners and used the emission reduction calculation results as stimulus material during the interviews. The results showed that emission reductions might not be the primary driver for investments in energy efficiency.

In the EU, this blend could be implemented to reduce the greenhouse gases (GHGs) emissions of the 8.3 million passenger cars currently fuelled with LPG. The blend exploits the transformation of waste products such as used cooking oils, organic wastes, and non-recyclable plastics into fuels, thus helping the transition to a circular economy. Practical use of the blend is possible, as its use resulted in compliance with the standards on marketing (EN 589:2018) and use (Euro 6) of LPG in passenger cars. According to the results of this study, for all the impact categories, the magnitude of impacts increases as the car size increases. Depending on the car segment, the blend reduces GHG emissions by 16-21% compared to petrol, and it shows preference over petrol in 5 impact categories out of 16, while being disadvantageous in 2-5 categories. Electric cars outperform petrol in the same 5 categories (reducing GHG emissions by 36-38% compared to petrol) but are detrimental in ten others. The study revealed increases higher than 200% in water consumption, for all the alternative propulsion systems. Future efforts should focus on fully renewable blends and address the potential limitations of waste feedstock availability used as input for the blend production.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"27 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143665987","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}
