Relevant reasons might include a lack of a clear understanding of what a CE theory can be, the prevalence of gap-spotting research, and a lack of a common goal for CE scholars. First, this forum article defines “CE theory” adopting a positivistic approach. Second, the article presents a more organized structure toward the development of a CE theory oriented on empirical practices. In addition, this study highlights how the development of “partial CE theories” focusing on specific CE practices, or a combination of them, should be the first step toward an integrative CE theory. Third, the paper suggests two main ways for developing partial CE theories: (i) consolidating concepts already developed into elements of a theoretical framework; (ii) framing future pieces of explicative research that contribute to partial CE theories. Last, by adopting a positivistic approach and a practical-oriented perspective, this research provides an example of contribution to the partial theory of reuse. In particular, by leveraging the form of propositional theorizing, this article explains why reuse practices are expected to be observed in industries characterized by a high degree of product modularization, standardization, and innovation. In doing so, this forum article aims to enrich and foster theoretical contributions of future CE studies.","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 2","pages":"418-428"},"PeriodicalIF":4.9,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143826993","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}

This opens up a synergistic opportunity for the petrochemical industry to utilize the captured CO2 as a feedstock, potentially helping both sectors reduce their carbon footprints. We conducted a prospective carbon footprint analysis on various net-zero strategies within the Swiss WtE plants (CCU and CCS) and German ethylene production (CO2-based ethylene, bio-ethylene, and fossil ethylene with CCS), including scenarios of industrial symbiosis. While focusing on these two countries, the findings offer valuable insights applicable to similar sectors in other regions. All assessed pathways reduce the carbon footprint by at least 60% relative to the reference scenario (no carbon capture in WtE plants and fossil ethylene production). Bio-ethylene and direct air capture–based ethylene combined with CCS in WtE exhibit the lowest climate change impacts, achieving net negative emissions when powered by renewable electricity. However, these pathways all come with trade-offs: The availability of sustainable biomass and low-carbon electricity is limited, and future resource competition may delimit the penetration of these technology combinations. CCS in ethylene production plants could reduce emissions while utilizing existing infrastructure but does not eliminate emissions from fossil fuel extraction. Ethylene produced with CO2 from WtE plants could be a viable interim solution until CCS barriers are overcome.","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 2","pages":"486-502"},"PeriodicalIF":4.9,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143826986","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}

Our study revisits the trade-offs through the perspective of population heterogeneity. Specifically, transitioning the Chinese diet from its 2011 baseline to a healthier alternative with minimal behavioral adjustments could intensify environmental and economic impacts by 1.3–2.3 times. Conversely, relaxing behavioral constraints can yield both environmental and economic benefits. Specifically, replacing red meats (beef, mutton, pork) with poultry and seafood helps reduce cost, while substituting both red meats and seafood with more poultry, fruits, and vegetables enhances environmental benefits. However, this adaptive approach is not universally applicable. Stringent constraints aimed at mitigating environmental or economic impacts may inadvertently marginalize specific groups, such as the rural, elderly, or low-income populations, denying them the advantages of healthier dietary options. These findings highlight the necessity of developing inclusive strategies that support the healthy dietary shift of vulnerable groups.","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 2","pages":"503-517"},"PeriodicalIF":4.9,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143826985","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}

Understanding the role of such strategies at the municipal level requires a localized approach. Here we evaluate a ramp-up of resource efficiency strategies and their associated effects on car use and climate benefits toward 2050 for 19 individual subregions within the Greater Oslo region in Norway. In our scenarios, material stocks increase from 356 megatonnes (Mt) in 2022 to 361–381 Mt in 2050 driven by population growth, with low-end estimate relying on a sufficiency (SUF) scenario limiting floor area per capita and banning new single-family houses. The SUF scenario reduces total material consumption until 2050 (50.5 Mt) with 28% relative to a business-as-usual (BAU) scenario (70.8 Mt) with continuation of ongoing trends, thereby reducing greenhouse gas (GHG) emissions from material production by 21% (BAU: 11.8 MtCO2-eq, SUF: 9.4 MtCO2-eq). If resource efficiency strategies are combined with material production decarbonization in-line with a 2°C scenario, a 35% reduction in emissions is achievable (7.7 MtCO2-eq). Car ownership rates and traveled distance per capita decrease in the SUF scenario compared to 2022 with 11%. Assuming the current relationship between settlement characteristics and transport demand, total driving distance fails to decline due to population growth. Limiting the floor-area per capita in residential buildings significantly decreases material demand. Resource efficiency strategies including densification need to be complemented with a rapid decarbonization of material supply and stronger incentives to move away from car driving to maximize climate change mitigation.

However, few studies have revealed the dynamic response of N emissions to diverse land use changes at the regional scale. This study developed a holistic spatial urban metabolism framework that combines land-use classification, N-flow modeling, and spatial analysis to examine the heterogeneous land-related N transitions across cities and timeframes at a fine spatial resolution. Using the Guangdong–Hong Kong–Macao Greater Bay Area (GBA) as the case, we observed a drastic expansion of built-up land during 1990–2018, mainly converted from cropland (81.35%) and forest (9.55%). Intensified N emissions became increasingly concentrated in densely populated urban areas and croplands in the GBA's western peripheral cities. Land conversion from cropland to built-up land contributed the most to the rise in N emissions, totaling 368.2 Gg during the study period. The increase in N emission intensity associated with built-up land expansion gradually fell over time due to enhanced N removal in waste treatment, while the exploitation of water and wetland exhibited the highest average increased intensity of 35.01 t N/km2 after 2010. Our findings highlight the need for tailored and collaborative land management strategies that adapt to different development stages and local conditions to mitigate N pollution in the fast-urbanizing bay area.","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 2","pages":"458-472"},"PeriodicalIF":4.9,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143826723","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}

Addressing the problems of construction and demolition waste production requires a comprehensive and multifaceted approach and specific attention to the development of sustainable circular on-site practices. This study compares recycled products against conventional products already available on the market. This study applied a life cycle assessment (LCA) to evaluate the benefits of secondary raw material (SRM)-based products compared to conventional virgin raw materials. Focusing on a Spanish case study that had foreseen the revitalization of a degraded area, the construction of a small utility building, and road construction, this analysis also assessed the overall environmental footprint of the overall construction work. The results showed that, despite the impact savings achieved by opting for SRM-based products rather than conventional solutions, the production stages still have the greatest impact on the scale of construction, with the sole exception of the construction of small facilities where the construction itself was the largest contributor. Climate change; water scarcity; freshwater eutrophication; resource use, energy carriers; and resource use, minerals and metals were the most significant impact categories both in the analysis of the construction products and the overall construction work. An LCA is vital in the construction and demolition sector because it provides a holistic understanding of the environmental impacts associated with the different stages of a project's life cycle fostering the implementation of circular on-site practices.","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 2","pages":"473-485"},"PeriodicalIF":4.9,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jiec.13614","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143826722","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}

In this study, we analyze 1068 publications within the IE–AI domain using trend factor analysis, word2vec modeling, and top2vec modeling. These methods uncover patterns of topic interconnections and evolutionary trends. Our results identify 71 trending terms within the selected publications, 69 of which, such as “deep learning,” have emerged in the past 8 years. The word2vec analysis shows that the application of various AI techniques is increasingly integrated into life cycle assessment and the circular economy. The top2vec analysis suggests that employing AI to predict and optimize indicators related to products, waste, processes, and their environmental impacts is an emerging trend.

However, empirical evidence is inconclusive and often subject to high uncertainties. Here, we explore long-term trends in the lifetimes of large household appliances using dynamic material flow analysis. We investigate the sales and ownership of these products since their introduction in Norwegian households and use this co-evolution to estimate the lifetimes. By combining two model types with uncertainty analysis, we show that a significant lifetime decrease was likely experienced only by washing machines (–45%) and ovens (–39%) around the 1990s–2000s. This finding challenges the narratives about planned obsolescence despite their prevalence decreasing consumer incentives for longer product use and repair. We suggest multiple technical, economic, and social factors that could be responsible for the decrease, for example, a reduction in relative prices of appliances or changes in habits surrounding laundry and kitchen use. Our results suggest that factors affecting product lifetimes are not uniform but context-dependent, which has implications for lifetime extension policy. The presented method could help monitor the long-term effectiveness of such a policy.

However, the journey from idea to market is highly uncertain and involves intensive trial and error as technology developers attempt to optimize material choices and product configurations. Designs evolve quickly, and assessing their risks and impacts while numerous factors remain undetermined is challenging. The standard practice is to evaluate a limited subset of scenarios that can guide design choices. However, selecting scenarios from hundreds of undetermined factors without a systematic sensitivity screening may leave out important improvement opportunities. To provide well-informed guidance, the evaluated scenarios should be selected based on factors that are most influential to the safety and sustainability impacts of the technology. We propose an approach that accomplishes this by incorporating a wide spectrum of undetermined factors, both intrinsic and extrinsic to the technology design. The assessment models are then screened for highly-sensitive factors using global sensitivity analysis. Strategies to reduce uncertainty on highly influential factors are proposed for subsequent iterations, and the residual factors for which uncertainty cannot be further reduced yet remain influential are selected as a basis for proposed “sensitive scenarios” and improvement roadmaps. We demonstrate the framework with an emerging photovoltaics case study. Over a hundred uncertain factors are reduced to less than five which, if optimized, would substantially improve the future safety and sustainability performance of the technology as well as reduce the uncertainty around it.","PeriodicalId":16050,"journal":{"name":"Journal of Industrial Ecology","volume":"29 1","pages":"47-65"},"PeriodicalIF":4.9,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jiec.13609","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466191","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}
