Incorporating coal fly ash (CFA), a byproduct of coal combustion, into cementitious materials is a promising strategy for reducing the consumption of natural resources and mitigating environmental burdens. Although flotation effectively lowers the unburned carbon content in CFA to enhance its recyclability, the associated carbon emissions and economic costs necessitate rigorous sustainability evaluations. This study evaluates the environmental-economic trade-offs of CFA flotation at a Technology Readiness Level (TRL) 6 (pilot scale), utilizing integrated life cycle assessment (LCA) and life cycle cost analysis (LCCA). Instead of static modeling, a Calorific-Based Economic Valuation (CBEV) framework is introduced to optimize process parameters by coupling market pricing mechanisms with flotation grade-recovery. The results revealed that kerosene and turpentine oil dosages critically influenced system performance: overuse caused economic losses, whereas optimal conditions (1 % kerosene + 0.1 % turpentine oil per ton of CFA) achieved a carbon benefit of 94.29 kg CO₂-eq (247.70 % improvement) and a net benefit of 0.986 USD/t (4.69 % return). Sensitivity analysis reveals that the adoption of electric vehicles yields synergistic environmental and economic benefits. In contrast, a 50 % increase in transport distance reduces economic returns by 3.6 %, despite a marginal variation in carbon footprint (<5 %), highlighting the importance of logistics optimization. Based on industrial scale-up principles, these results represent a conservative baseline for informing future industrial applications. This study establishes a dual-perspective framework for assessing the feasibility of CFA flotation and provides quantitative insights to support sustainable process intensification.

将煤燃烧的副产品粉煤灰掺入胶凝材料中是一种很有前景的减少自然资源消耗和减轻环境负担的策略。虽然浮选有效地降低了CFA中未燃烧的碳含量，提高了其可回收性，但相关的碳排放和经济成本需要严格的可持续性评估。本研究利用综合生命周期评估（LCA）和生命周期成本分析（LCCA），评估了技术就绪水平（TRL） 6（中试规模）下CFA浮选的环境经济权衡。采用基于热量的经济评价（CBEV）框架代替静态模型，通过将市场定价机制与浮选品位回收率相结合来优化工艺参数。结果表明，煤油和松节油的用量严重影响系统性能：过度使用会造成经济损失，而最佳条件（每吨CFA 1%煤油+ 0.1%松节油）的碳效益为94.29 kg co2当量（改善247.70%），净效益为0.986美元/吨（回报4.69%）。敏感性分析表明，采用电动汽车产生协同的环境效益和经济效益。相比之下，运输距离增加50%，尽管碳足迹略有变化（5%），但经济回报减少3.6%，凸显了物流优化的重要性。基于工业规模放大原则，这些结果代表了为未来工业应用提供信息的保守基线。本研究建立了一个评估CFA浮选可行性的双重视角框架，并提供了定量的见解，以支持可持续的过程强化。

The construction sector has been struggling to implement plastic waste management strategies that promote plastic circularity, and limited understanding persists regarding the barriers to reducing, reusing, and recycling plastic waste. This knowledge gap is compounded by the diversity of plastic products, the unique role of construction companies in the circular economy, and the complexity of the construction plastics’ value chain. This study aims to generate knowledge to support construction companies in improving plastic waste management in the European context. We investigate relevant barriers through a life cycle perspective and considering the diversity of construction plastics. By compiling product data, a construction plastic product list was created, covering 38 product types across seven categories with 18 polymer options. In parallel, a literature review and thematic analysis was conducted to construct a life cycle-based and circularity strategy (Reduce, Reuse, Recycle)-categorized barrier overview. The diversity of construction plastics was considered in the barrier analysis, revealing how the relevance of specific barriers varies across products.

A total of 129 barriers to recycling, 124 to reuse, and 39 to reduction were identified. Results highlight that the Construction life cycle stage faces the highest number of barriers across all three strategies. These barriers are predominantly activity-related, such as 17 “Collection & Sorting” barriers for recycling, 12 “Design” barriers for reuse, and 4 “Installation” barriers for reduction. The life cycle stage-based, strategy-specific, and product-specific perspectives on barriers provide a structured foundation for construction companies to set strategic priorities and develop targeted and effective plastic waste management strategies.

建筑行业一直在努力实施促进塑料循环的塑料废物管理战略，但对减少、再利用和回收塑料废物的障碍的认识仍然有限。塑料产品的多样性、建筑公司在循环经济中的独特作用以及建筑塑料价值链的复杂性加剧了这种知识差距。这项研究的目的是产生知识，以支持建筑公司在欧洲范围内改善塑料废物管理。我们通过生命周期的角度研究相关障碍，并考虑到建筑塑料的多样性。通过整理产品数据，创建了建筑塑料产品清单，涵盖7大类38种产品类型，18种聚合物选项。同时，通过文献综述和专题分析，构建了基于生命周期和循环策略（Reduce, Reuse, Recycle）分类的屏障概述。在屏障分析中考虑了建筑塑料的多样性，揭示了特定屏障在不同产品中的相关性。共确定了129个回收障碍、124个再利用障碍和39个减量化障碍。结果强调，在所有三种策略中，建筑生命周期阶段面临的障碍最多。这些障碍主要是与活动相关的，例如17个“收集和分类”障碍用于回收，12个“设计”障碍用于再利用，4个“安装”障碍用于减少。基于生命周期阶段、特定战略和特定产品的障碍视角为建筑公司设定战略重点和制定有针对性和有效的塑料废物管理战略提供了结构化的基础。

The transition to a circular economy (CE) requires systemic perspectives to comprehend the complex behaviours of actors and support their decision-making processes. Agent-based modelling (ABM) has proven to be a promising approach to studying complex nonlinear phenomena in human and natural systems like CE. This critical review paper aims to understand the current state of ABM application in CE research and explore potential future study areas. Bibliometric and content analyses were applied with a stock of 45 articles employing ABM in CE, in addition to 13,797 CE articles that have not utilized ABM. The results called for expanding the application areas of CE research using ABM, focusing on policy and institutional environment, sustainable life cycle management, broadening scope of CE strategies, and social and environmental impacts. The content analysis revealed the need to employ more robust and up-to-date methodologies, such as theories underpinning agent behaviours, data sources and assumptions, validation and simulation procedure, replication of model runs, model representation and documentation, and stakeholders’ participation in the modelling process. This study introduces a participatory-integrated framework designed to equip CE researchers employing ABM with guidance for robust modelling and simulation practices. Such ABMs will offer valuable insights for developing effective policies, strategies, and business practices toward enhanced sustainability.

向循环经济的过渡需要系统的视角来理解参与者的复杂行为并支持他们的决策过程。基于主体的建模（ABM）已被证明是研究人类和自然系统（如CE）中复杂非线性现象的一种很有前途的方法。本文旨在了解ABM在CE研究中的应用现状，并探讨潜在的未来研究领域。文献计量学和内容分析应用于在CE中使用ABM的45篇文章，以及未使用ABM的13797篇CE文章。结果表明，利用ABM方法扩大环境行政研究的应用领域，重点关注政策和制度环境、可持续生命周期管理、扩大环境行政战略的范围以及社会和环境影响。内容分析显示，需要采用更强大和最新的方法，例如支撑代理行为的理论、数据源和假设、验证和模拟程序、模型运行的复制、模型表示和文档，以及利益相关者参与建模过程。本研究引入了一个参与式集成框架，旨在为采用ABM的CE研究人员提供稳健建模和仿真实践的指导。这些ABMs将为制定有效的政策、战略和商业实践提供有价值的见解，以增强可持续性。

This study investigates why digital transformation often leads to inconsistent results in traditional industries. While many assume that technology always improves performance, most research relies on simple "checklists" of technology adoption (breadth). We challenge this view by distinguishing between digital adoption depth (strategic integration) and breadth (simple accumulation). Using data from 321 Spanish wineries and Partial Least Squares Structural Equation Modeling, we test whether production process flexibility, viewed as a dynamic capability, is the link between digital tools and firm performance. Our findings reveal a sharp contrast: digital depth is a strong predictor of flexibility and clean production, while breadth is largely ineffective. We establish that strategic integration, not mere acquisition, is the true driver of value in digitalization.

本研究探讨了为什么传统行业的数字化转型往往导致不一致的结果。虽然许多人认为技术总是能提高性能，但大多数研究依赖于技术采用（广度）的简单“清单”。我们通过区分数字采用深度（战略整合）和广度（简单积累）来挑战这一观点。利用321家西班牙酒庄的数据和偏最小二乘结构方程模型，我们测试了生产过程的灵活性，作为一种动态能力，是否是数字工具和企业绩效之间的联系。我们的研究结果揭示了鲜明的对比：数字深度是灵活性和清洁生产的有力预测指标，而广度在很大程度上是无效的。我们认为，战略整合，而不仅仅是收购，才是数字化价值的真正驱动力。

Agricultural areas are faced with the dual challenge of reducing their environmental impacts while adapting to climate change. Adaptations rely on strategies such as irrigation or cultivated crop diversification, whose environmental performance over time is affected by climate change. Such environmental performance can be studied by combining Territorial Life Cycle Assessment (T-LCA) with crop modeling. However, the identification of optimal planning scenarios within the multiplicity of adaptation possibilities that could be assessed hinder the use of classical scenario analyses that could be costly in computing time and not rigorous enough to cover every scenario. Therefore, a methodology coupling experimental design with T-LCA and crop modeling is conceived to investigate the environmental performance of various agricultural planning scenarios in a climate change context. The usefulness of this methodology is proven through a theoretical case study of an agricultural territory using different crop combinations, with or without irrigation, within the context of the worst-case IPCC scenario of climate change (SSP5-8.5). Environmental performance is quantified with eco-efficiency. Eco-efficiency means values and variabilities are calculated over the next 30 years to identify scenarios maintaining highest performance over time. The proposed innovative coupling enables a full investigation of the environmental performance of agricultural land management scenarios integrating different modalities. This study demonstrates that under low interannual variability of fertilisation practices, irrigation and crop diversity contribute to the stabilisation of environmental performance related to the impacts on climate change. Further developments are required for a more robust modelling of agro-ecosystem functioning for application to real-world cases.

农区面临着减少环境影响和适应气候变化的双重挑战。适应依赖于灌溉或栽培作物多样化等策略，这些策略的环境绩效随着时间的推移受到气候变化的影响。这种环境绩效可以通过将领土生命周期评估（T-LCA）与作物建模相结合来研究。然而，在可评估的多种适应可能性中确定最佳规划情景阻碍了经典情景分析的使用，这些分析可能耗费大量计算时间，而且不够严格，无法涵盖所有情景。因此，我们设想了一种将实验设计与T-LCA和作物建模相结合的方法，以研究气候变化背景下各种农业规划情景的环境绩效。在IPCC气候变化最坏情景（SSP5-8.5）的背景下，通过对使用不同作物组合（有或没有灌溉）的农业地区进行理论案例研究，证明了该方法的实用性。环境绩效用生态效率来量化。生态效率意味着计算未来30年的价值和变化，以确定随着时间的推移保持最高性能的情景。所提出的创新耦合能够对整合不同模式的农业用地管理情景的环境绩效进行全面调查。该研究表明，在施肥方式年际变化较小的情况下，灌溉和作物多样性有助于与气候变化影响相关的环境绩效的稳定。需要进一步发展一个更可靠的农业生态系统功能模型，以便应用于现实世界的案例。

Escalating ecological challenges, such as global warming and environmental pollution, have made carbon emission control and enhanced environmental governance global priorities. Concurrently, growing external uncertainties have intensified instability in global value chains (GVCs), causing disruptions like bottlenecks and breakdowns. This study measures GVC resilience using input-output data from the OECD-ICIO database (2000–2020) and applies a country-industry-year fixed-effects model to investigate how environmental regulations—aimed at reducing pollution and carbon emissions—influence GVC resilience. Results show that environmental regulation exerts dual effects: it reduces GVC volatility but increases security risks. Further analysis reveals that these regulations weaken GVC resilience mainly by raising costs and hindering technological innovation, while they improve stability through trade facilitation (though at the cost of security). Notably, improved energy efficiency strengthens GVC resilience. This research provides theoretical insights and policy implications for enhancing GVC resilience via environmental regulation.

全球气候变暖和环境污染等生态挑战日益加剧，控制碳排放和加强环境治理成为全球优先事项。与此同时，外部不确定性的增加加剧了全球价值链的不稳定性，导致瓶颈和故障等中断。本研究使用来自OECD-ICIO数据库（2000-2020年）的投入产出数据来衡量全球价值链弹性，并应用国家-行业-年度固定效应模型来研究旨在减少污染和碳排放的环境法规如何影响全球价值链弹性。结果表明，环境规制具有双重效应：一方面降低了全球价值链波动，另一方面增加了安全风险。进一步分析表明，这些法规主要通过提高成本和阻碍技术创新来削弱全球价值链的弹性，同时通过贸易便利化（尽管以安全为代价）来提高稳定性。值得注意的是，能源效率的提高增强了全球价值链的韧性。本研究为通过环境规制增强全球价值链弹性提供了理论见解和政策启示。

A key methodological challenge in using Life Cycle Assessment (LCA) for agricultural decision support is the definition of the system’s function and functional unit (FU). In complex, multifunctional agricultural systems, this choice is often ambiguous and can significantly alter study outcomes, complicating the comparability and interpretation of results and posing a challenge for decision-making. To situate this problem, we first present a focused review of 34 recent LCA studies, which confirms the diversity of current practices and underscores the need for a more structured selection approach. In response to this identified gap, this paper develops a conceptual framework for selecting appropriate FUs. The framework includes a taxonomy that classifies agricultural functions according to key stakeholder perspectives: the consumer (product function), the producer (income function), and society (land management function). Building on this classification and the challenges highlighted by the literature review, we introduce five evaluative criteria: completeness, proportionality, specificity, stability, and accessibility. These criteria are designed to guide researchers and practitioners in selecting and justifying FUs that align with specific decision contexts. By shifting the focus from a single “correct” FU to a context-appropriate one, our framework provides a robust and transparent methodology to enhance the relevance and utility of LCA in supporting sustainable agriculture.

将生命周期评估（LCA）用于农业决策支持的一个关键方法论挑战是系统功能和功能单元（FU）的定义。在复杂的多功能农业系统中，这种选择往往是模棱两可的，可能会显著改变研究结果，使结果的可比性和解释复杂化，并对决策构成挑战。为了解决这个问题，我们首先对34项最近的LCA研究进行了重点回顾，这些研究证实了当前实践的多样性，并强调了更结构化的选择方法的必要性。为了回应这一发现的差距，本文开发了一个选择适当的FUs的概念框架。该框架包括一个分类法，根据关键利益相关者的观点对农业功能进行分类：消费者（产品功能）、生产者（收入功能）和社会（土地管理功能）。基于这种分类和文献综述所强调的挑战，我们引入了五个评估标准：完整性、比例性、特异性、稳定性和可及性。这些标准旨在指导研究人员和实践者选择和证明与特定决策环境一致的FUs。通过将重点从单一的“正确”FU转移到与环境相适应的FU，我们的框架提供了一个强大而透明的方法，以增强LCA在支持可持续农业方面的相关性和实用性。

The circular economy (CE) is widely seen as a path to sustainability, yet it remains unclear whether its indicators fully reflect its overall contribution. Despite rapid growth, current classifications of CE indicators remain fragmented and are often based on limited datasets. To address this, this study maps 2701 CE indicators to provide a comprehensive overview of their thematic and structural distribution. A six-domain framework was applied (covering environmental, economic, social, circularity, technological, and legislative dimensions) and organized into 21 classes and 118 subgroups. To address inconsistencies, a hybrid labeling approach was introduced for classifying data types and economic levels. Results show that CE indicators collectively span all sustainability domains but remain unevenly distributed, with quantitative and meso-level indicators prevailing and micro-level ones underrepresented. Three key insights emerge: (1) large datasets reduce bias in CE assessment; (2) multi-level classification enables clearer interpretation; and (3) binary labeling oversimplifies contextual complexity. Overall, this mapping demonstrates that CE measurement has expanded beyond traditional circularity metrics toward broader sustainability integration, providing a foundation for more coherent indicator development and policy alignment.

循环经济（CE）被广泛视为可持续发展的途径，但其指标是否充分反映了其总体贡献尚不清楚。尽管增长迅速，但目前的CE指标分类仍然支离破碎，而且往往基于有限的数据集。为了解决这个问题，本研究绘制了2701个CE指标，以提供其主题和结构分布的全面概述。采用了六域框架（涵盖环境、经济、社会、循环、技术和立法维度），并将其分为21个类和118个子组。为了解决不一致性，引入了一种混合标记方法来对数据类型和经济水平进行分类。结果表明，可持续发展指标总体上跨越所有可持续发展领域，但分布不均匀，定量和中观水平指标占主导地位，微观水平指标代表性不足。有三个关键的见解：(1)大数据集减少了CE评估的偏见；(2)多层次分类，解释更清晰；(3)二元标记过度简化了上下文复杂性。总体而言，这一映射表明，CE测量已经从传统的循环度量扩展到更广泛的可持续性整合，为更连贯的指标开发和政策调整提供了基础。

Man-made cellulosic fibers (MMCF) are a renewable alternative to fossil-based synthetic fibers due to potentially reduced environmental impacts and competitive properties in comparison to other fibers commercially available such as cotton. Although significant research is done on enhancing the technical properties and production of MMCF, the successful commercial implementation relies on sustainable (economic, environmental and social) upscaling of MMCF production. Therefore, this study examines publications focusing on techno-economic, environmental and social assessments of MMCF to identify potential sustainability indicators to support the upscaling of MMCF. There are a limited number of peer-reviewed studies entailing the economic and social domains of MMCF sustainability. Environmental impacts have been evaluated more frequently. The economic barriers were reported to be the price of dissolving pulp, solvent recovery, capital expenditure, and energy consumption. 19 papers were found covering environmental sustainability, most of them applying LCA from cradle to gate for fiber production. Environmental impact assessments show that the most significant potential impacts were greenhouse gas emissions, water use, abiotic resource use, eutrophication, acidification and change in land use. It was possible to identify the indicators that occur in more than one domain of sustainability such as energy and water consumption, resource use and chemicals recyclability. However, none of the studies identified has focused on indicators that include all three domains. Further studies on economic and social sustainability coupled with environmental sustainability could support the identification of robust indicators, tradeoffs and support paving the way to sustainable upscaling of MMCF.

人造纤维素纤维（MMCF）是化石基合成纤维的可再生替代品，因为与棉花等其他市售纤维相比，它可能减少对环境的影响，并具有竞争力。虽然在提高MMCF的技术性能和生产方面进行了大量研究，但成功的商业实施依赖于MMCF生产的可持续（经济、环境和社会）升级。因此，本研究考察了关注MMCF技术经济、环境和社会评估的出版物，以确定潜在的可持续性指标，以支持MMCF的升级。涉及MMCF可持续性的经济和社会领域的同行评议研究数量有限。对环境影响的评价更加频繁。据报道，经济障碍是溶解纸浆的价格、溶剂回收、资本支出和能源消耗。共发现19篇论文涉及环境可持续性，其中大部分将LCA应用于纤维生产的全过程。环境影响评价表明，最显著的潜在影响是温室气体排放、水利用、非生物资源利用、富营养化、酸化和土地利用变化。可以确定在能源和水的消耗、资源的利用和化学品的可回收性等一个以上的可持续性领域中出现的指标。然而，所确定的研究中没有一项侧重于包括所有三个领域的指标。对经济和社会可持续性以及环境可持续性的进一步研究可以支持确定强有力的指标、权衡和支持为可持续地扩大MMCF铺平道路。

This study combines a global mass-flow analysis of technically recoverable agricultural residues with dynamic life cycle assessment to quantify climate benefits of diverting biomass into long-lived building products. Annual flows were linked to the Bern Impulse Response Model (BernSCM), radiative forcing and temperature response under different scenarios diverting biomass from combustion routes such as open burning, combined heat and power and biofuel production to long-term storage. The assessment showed that a complete diversion from combustion with renewable energy backfill provides persistent cooling with a median radiative forcing of −0.6 W m^-2 and -0.35 °C at 100 years. Allocating an additional 50 Mha of high-yield crops increases long-term cooling but is offset by early land-use emissions. Scenarios, constrained by projected global building materials demand produced much smaller effects in the range of 0.0041–0.0082 W m^-2 in radiative forcing and 0.0031–0.0062 °C cooling for bio-based market increasing from 1 % to 25 % and 50 % in the next 25 years. Sensitivity analysis shows uncertainty dominated by service life and end-of-life scenarios, while substitution credit and allocation shares resulted in a smaller influence. The results indicate that while fibrous residues could act as a significant carbon sink, their full potential requires expanding beyond insulation materials or deployment into other long-lived construction applications.

本研究将技术上可恢复的农业残留物的全球质量流分析与动态生命周期评估相结合，以量化将生物质转化为长寿命建筑产品的气候效益。年流量与伯尔尼脉冲响应模型（BernSCM）、不同情景下的辐射强迫和温度响应有关，这些情景使生物质从露天燃烧、热电联产和生物燃料生产等燃烧途径转向长期储存。评估表明，使用可再生能源充填体完全转移燃烧，可提供持续冷却，100年的平均辐射强迫为- 0.6 W m-2和-0.35°C。额外分配50万公顷的高产作物增加了长期降温，但被早期土地利用排放所抵消。受预计的全球建筑材料需求约束的情景，在辐射强迫0.0041-0.0082 W m-2和0.0031-0.0062°C冷却范围内产生的影响要小得多，生物基市场在未来25年内将从1%增加到25%和50%。敏感性分析表明，不确定性主要受使用寿命和寿命终止情景的影响，而替代信用和分配份额的影响较小。结果表明，虽然纤维残留物可以作为一个重要的碳汇，但其全部潜力需要扩展到绝缘材料或部署到其他长寿命的建筑应用中。
