However, the application of SE practices in the construction industry (CI) remains comparatively low due to the absence of identification of factors and strategies to enhance overall sharing practices. In light of this, the present study aims to identify and prioritize the strategies for enhancing factors influencing SE practices in the CI. This study proposes a framework incorporating Stepwise Weight Assessment Ratio Analysis (SWARA) and Weighted Aggregated Sum Product Assessment (WASPAS) techniques to achieve the aim of this study. The relative influence of factors was evaluated using SWARA, while WASPAS was used to prioritize strategies of SE practices in the construction domain. Twenty-four SE factors and 29 strategies were identified and finalized through the preliminary data collection stage (literature review, semi-structured interviews, and questionnaire survey) and discussions with industry experts as the primary data collection. The findings reveal that “additional income generation” is the top-ranked factor, while “provide education and training and establish incubation centers” is the top-ranked strategy in SE practices in the CI. In the end, a sensitivity analysis with 15 experiments was conducted to observe the robustness of the results.

Applied to Hong Kong, the framework reallocates indirect emissions based on inter-sectoral electricity flows and reduces the supply-to-demand emission distribution from 3.52 to 1.25, promoting a fairer distribution of emission responsibilities among sectors. Beyond tracing emission dynamics, it simulates mitigation scenarios under shared socioeconomic pathways to assess the value of cross-sectoral coordination. Results show that redistributing responsibilities and enhancing cross-sectoral collaboration can improve city-level mitigation performance, with synergistic policies projected to reduce emissions by 37.3% and 19.1% by 2050 compared to limited or no coordination.

Models of metal supply systems can help enhance our understanding of these systems and identify strategies to reduce material criticality and improve resilience. In this work, we introduce a novel approach to modeling metal supply systems, using nickel as a case study. Our approach combines system dynamics modeling, in which various feedback loops influence future outcomes, with the higher sectoral and geographical detail of industrial ecology (IE) methods and data on individual mines. We also include extensive uncertainty analyses through exploratory modeling and analysis. Using this combined modeling approach, we explore the development and resilience of the global nickel supply system between 2015 and 2060 under various uncertainties and policy levers. Our results show that incorporating feedback effects leads to more realistic demand behavior and resource depletion patterns compared to traditional dynamic material flow analysis. Market feedback enhances resilience, but cannot fully offset criticality risks. Sectoral disaggregation reveals increased criticality risks due to the energy transition, which can be mitigated by increasing opportunities for substitution, product lifetime extension, recycling, exploration, capacity expansion, and by-product recovery. Geographical disaggregation highlights the resilience benefits of diverse supply sources, as well as the effects of changing regional market shares on sustainability impacts, ore grade variability, and by-product dynamics. Our combined modeling approach is a step toward prospective, dynamic criticality assessment, in which system changes and future risks are accounted for when determining material criticality and policy recommendations.</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 5","pages":"1666-1683"},"PeriodicalIF":5.4,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jiec.70072","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Although the global primary tungsten supply is concentrated in China, the grade of such ore is deteriorating, leading to more consideration of promoting the reuse and recycling of tungsten scraps. However, the environmental impacts induced by tungsten recycling have not been investigated, which may influence the appropriate circular economy implementation along the entire tungsten industrial chain. This study aims to identify the “side effects” of tungsten recycling by comparing the pros and cons of primary/secondary tungsten production from a life cycle perspective. The environmental impacts of the primary tungsten production system (W-PPS), direct recycling system (W-DRS), and indirect recycling system (W-IRS) are estimated by using 18 mid-point indicators in human health, ecosystems, and resources categories. Results indicate that switching to W-DRS and W-IRS from W-PPS could help reduce environmental burdens in terms of major mid-point indicators, except human non-carcinogenic toxicity and terrestrial ecotoxicity. Energy and chemical raw materials input contribute the most to the above environmental impacts. Based upon these findings, we propose that serious regulations should be implemented for both primary and secondary production systems, as well as appropriate urban mine actions and sustainable industrial design schemes.</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 5","pages":"1684-1697"},"PeriodicalIF":5.4,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Considering the present Indian policies focus on CDW recycling as the major CDW management strategy, the MaLBA model suggests that expanding Thane's recycling capacity from 300 to 700 Mt/Day can prove counterproductive to meet the national targets as the technical limitations of recycled material usage and limited user acceptance might lead to an oversupply of recycled CDW products by 2050. Therefore, this study recommends focusing on market development by doubling efforts to advertise recycled products and expand recycling infrastructure in alignment with regional infrastructure growth.

The capital stock of each country is divided into four sectors: (i) energy production and distribution, (ii) production of goods and services for consumption, (iii) residential, and (iv) construction and manufacture of capital. The findings reveal diverse strengths and challenges in decarbonization efforts across the countries. Sweden excels in “energy production and distribution” and “residential” sectors, owing to its commitment to renewable energy and energy efficiency, but requires attention in goods and services production where carbon intensity is high. The United Kingdom stands out for its high greenhouse gas intensity in residential capital stock and in the consumption of goods and services, underscoring the need for targeted low-carbon investments. The United States and Canada display high GHG intensities across all sectors, necessitating a more robust transition toward renewable and low-carbon energy solutions. In particular, the United States’ carbon intensity in its energy sector and Canada's industry dominated by fossil fuel extraction offer specific areas for intervention. The study concludes that focusing on sectors with the highest carbon intensity and adopting both sector-specific and broader strategies can significantly accelerate each country's decarbonization efforts, thereby contributing to global climate change mitigation.

These methods include maintaining conventional production, adopting direct electrification, or implementing hydrogen-based technologies. Scenarios vary the assumptions on hydrogen and carbon dioxide emission allowance prices for 2035 and 2045. Which production methods are cost-effective, and therefore assumed to be implemented in the scenarios, depends on marginal abatement costs of carbon dioxide emissions across industries. For 2035, results show that only very low hydrogen prices and emission allowance prices above €200 per metric ton drive significant adoption of low-carbon production methods, with hydrogen demand ranging from nearly zero to 238 TWh and electricity demand from 54 to 197 TWh. Scenarios for 2045 assume full defossilization, with hydrogen demand ranging between 267 and 419 TWh and electricity requirements between 163 and 301 TWh. Across all scenarios analyzing 2045, 263 TWh of hydrogen are used as a reactant, a reductant, or for metallurgical purposes, making this demand portion, given the lack of other defossilization options, unavoidable when aiming for complete defossilization while maintaining domestic production. Additionally, the paper regionalizes selected scenario results based on site-specific data. The regionalization reveals a strong concentration of high hydrogen demands for use as a reactant and reductant at only a few sites, posing challenges for integration into the energy infrastructure, while hydrogen used for process heating shows a more decentralized distribution.</p>","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 5","pages":"1583-1600"},"PeriodicalIF":5.4,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jiec.70051","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}
