Marine plastic pollution threatens coastal and island communities. Initiatives to reduce plastic have raised awareness and stimulated behavioral changes among local populations. The tourism sector represents a complex dynamic, serving as a significant industry that bolsters numerous communities’ local economies. While tourism contributes to increased plastic consumption, it also has the potential to support pollution mitigation efforts to preserve the reputation of these destinations. This study aims to examine the attitudes and behaviors in reducing marine plastic pollution, with particular attention to the impact of interventions and tourism, as there remains a shortage of understanding regarding the drivers that affect waste reduction in island contexts. Data were collected from 300 residents on two neighboring islands in Central Vietnam through questionnaires developed based on the Theory of Planned Behavior (TPB) with an extension to tourists’ moral behaviors and trust in authority. The Kruskal–Wallis tests and path analysis revealed that interventions substantially improved plastic waste reduction behaviors. Furthermore, all factors within the TPB framework and its extensions displayed positive correlations with intention and behavior; notably, perceived behavioral control and trust in authority exhibited stronger associations than other variables. Interventions were identified as positive predictors of behavioral change, likely attributable to educational activities, the distribution of reusable bags, and community engagement initiatives. Conversely, tourism was found to exert mixed effects: it could discourage anti-plastic practices, possibly due to economic priorities, while encouraging such practices when tourists exemplify pro-environmental behaviors. Essential policy implications for marine plastic pollution within island communities were discussed.

海洋塑料污染威胁着沿海和岛屿社区。减少塑料的举措提高了当地民众的意识，并刺激了他们的行为改变。旅游业代表了一个复杂的动态，作为一个重要的产业，支持了许多社区的当地经济。虽然旅游业增加了塑料消费，但它也有可能支持减轻污染的努力，以维护这些目的地的声誉。本研究旨在研究减少海洋塑料污染的态度和行为，特别关注干预措施和旅游业的影响，因为对岛屿环境中影响减少废物的驱动因素仍然缺乏了解。通过基于计划行为理论（TPB）的问卷调查收集了越南中部两个邻近岛屿的300名居民的数据，并扩展了游客的道德行为和对权威的信任。Kruskal-Wallis测试和路径分析显示，干预措施大大改善了减少塑料废物的行为。此外，城市规划框架及其延伸范围内的所有因素都与意图和行为呈正相关；值得注意的是，感知行为控制和对权威的信任比其他变量表现出更强的关联。干预措施被认为是行为改变的积极预测因素，可能归因于教育活动、可重复使用袋子的分发和社区参与倡议。相反，研究发现旅游业会产生混合效应：可能出于经济优先考虑，它可能会阻碍反塑料做法，但当游客表现出环保行为时，它会鼓励这种做法。讨论了岛屿社区内海洋塑料污染的基本政策影响。

The textile and the furniture industries are responsible for huge environmental impacts. Thus, prompting sustainable production and consumption models, according to the UN sustainable development goal n.12, in these industries is essential. Developing industrial symbiosis (IS) practices between the textile and the furniture industries, through the use of textile industrial waste as input for producing furniture products and successfully marketing these products (IS products) can represent a key way to achieve this goal. A widespread diffusion of IS products in the market is needed to really lead to a reduction of environmental burdens. A deep knowledge of consumer perceptions and behavioral intentions towards IS products is thus needed. To this aim, a survey of 1156 Italian consumers has been conducted, with a specific focus on IS sofas. Results show that consumers perceive these products as being characterized by a high degree of green utility. Consumers also declare not to be willing to accept a worsening of performance, especially comfort and quality. While about 77 % would consider purchasing, a much lower percentage (<50 %) declare a high likelihood of purchasing such products. About 90 % of consumers state they are willing to pay a premium price for an IS sofa. Several aspects that would increase the purchase intention of an IS sofa are also identified. Consumer’s knowledge on is found to play a prominent role in positively influencing consumer’s perceptions and behavioral intention, as significant differences between respondents with a high level of IS knowledge and those with a low level are highlighted for attitude, purchase intention, green perceived utility, and for some factors that would increase the purchase intention. Implications for managers, scholars, and policy makers are drawn from this study.

纺织业和家具业对环境造成了巨大的影响。因此，根据联合国可持续发展目标n.12，在这些行业促进可持续的生产和消费模式是至关重要的。发展纺织和家具行业之间的工业共生（IS）实践，通过使用纺织工业废料作为生产家具产品的投入，并成功地营销这些产品（IS产品），可以代表实现这一目标的关键途径。要真正减少环境负担，需要在市场上广泛推广信息系统产品。因此，需要深入了解消费者对信息系统产品的看法和行为意图。为此，对1156名意大利消费者进行了一项调查，特别关注IS沙发。结果表明，消费者认为这些产品具有高度的绿色效用。消费者还表示，他们不愿意接受性能的恶化，尤其是舒适性和质量。虽然大约77%的人会考虑购买，但更低的比例（50%）表示很有可能购买此类产品。约90%的消费者表示，他们愿意为IS沙发支付高价。还确定了增加IS沙发购买意愿的几个方面。研究发现，消费者对is的知识对消费者的认知和行为意愿起到了显著的正向影响作用，在态度、购买意愿、绿色感知效用以及一些会增加购买意愿的因素上，is知识水平高的受访者与is知识水平低的受访者之间存在显著差异。本研究对管理者、学者和政策制定者的启示。

The implementation of circular economy concepts has become inevitable in the face of progressive resource depletion and increasing waste generation. However, in academia and industry, the focus is mainly on the conceptual, economic, or logistical implementation at a high level. At the product level, conducting a precise technological feasibility study and evaluating circularity strategies in different areas is crucial to facilitate the transition towards resource optimization and waste reduction. In this context, this study proposes a debonding-on-demand (DoD) of an innovatively designed polymer sandwich structure consisting of a lower-melting temperature additively manufactured polypropylene (PP) honeycomb core structure and a higher-melting temperature glass fiber prepreg embedded in a PP matrix. The innovatively developed design allows for disassembly, recycling and reassembly of the sandwich structure. Trough the additive manufacturing process, load path adaption, optimization, and adjustment of varying material properties is effortless realizable.In addition, the manufacturing process is supported by different service-life simulations. Based on primary data, a new, innovative, and comprehensive assessment of manufacturing, performance, cost, and sustainability is performed. With the collected manufacturing data, a disassembly index was developed to evaluate multi-component products. The results demonstrate the potential of customizable, additively manufactured sandwich structures based on thermoplastic materials. The newly developed debonding mechanism and the thermo-mechanical recycling enable the reuse of the core material with comparable properties. The proposed multi-domain-based disassembly index is a comprehensive tool to evaluate the feasibility of products or material combinations after their useful life and can support the transition to a more data-driven circular engineering approach.

面对日益枯竭的资源和日益增加的废物产生，实施循环经济理念已成为必然。然而，在学术界和工业界，重点主要放在高层次的概念、经济或后勤实施上。在产品层面，进行精确的技术可行性研究和评估不同领域的循环战略对于促进向资源优化和减少废物的过渡至关重要。在此背景下，本研究提出了一种创新设计的聚合物三明治结构的按需脱粘（DoD），该结构由低熔点增材制造的聚丙烯（PP）蜂窝核心结构和嵌入在PP基体中的高熔点玻璃纤维预浸料组成。创新开发的设计允许拆卸，回收和重新组装的三明治结构。通过增材制造过程，负载路径的适应，优化和调整不同的材料性能是毫不费力的实现。此外，制造过程由不同的使用寿命模拟支持。基于原始数据，对制造、性能、成本和可持续性进行了新的、创新的和全面的评估。利用收集到的制造数据，建立了多部件产品的拆解指标。结果显示了基于热塑性材料的可定制的、增材制造的夹层结构的潜力。新开发的脱粘机制和热机械回收使芯材的重复使用具有相当的性能。提出的基于多领域的拆卸指数是评估产品或材料组合在其使用寿命后可行性的综合工具，可以支持向更多数据驱动的循环工程方法的过渡。

The urgent necessity to mitigate climate change and reduce resource depletion is accelerating the shift toward sustainable materials in critical industries. Fiber-reinforced polymer (FRP) has been gaining attention as an alternative to steel and aluminum in construction, automotive, and pipeline applications due to its exceptional high-performance properties. However, the environmental implications of FRP remain a concern, predominantly due to energy-intensive production processes and end-of-life (EoL) challenges. This review offers a comprehensive, cross-sectoral analysis of life-cycle assessment (LCA) findings on FRP, highlighting sector-specific drivers, environmental trade-offs, and methodological limitations. Although use-phase benefits, such as reduced emissions and lower maintenance costs, are well documented, they are often offset by the high embodied energy and underdeveloped recycling infrastructure. Existing LCA studies have emphasized climate impacts, while underrepresenting various indicators, including human toxicity, resource depletion, and circularity. Methodological limitations, such as generic datasets, a lack of performance-based functional units, and simplified EoL modeling, compromise comparability. Mechanical recycling often yields low-quality output with reduced performance, limiting reuse in high-value applications, whereas thermal and chemical methods face challenges in energy and scalability. Future efforts must prioritize standardized LCA methods, region-specific background datasets, circular economy integration, and advanced recycling technology to realize the full sustainability potential of FRP. A strategic framework is necessary to enable the widespread use of FRP as a viable, low-carbon alternative in a net-zero future.

缓解气候变化和减少资源消耗的迫切需要正在加速关键行业向可持续材料的转变。纤维增强聚合物（FRP）由于其优异的高性能，作为钢和铝的替代品，在建筑、汽车和管道应用中越来越受到关注。然而，FRP对环境的影响仍然令人担忧，主要是由于能源密集型的生产过程和寿命终结（EoL）的挑战。本综述对FRP的生命周期评估（LCA）结果进行了全面的、跨部门的分析，强调了特定部门的驱动因素、环境权衡和方法局限性。虽然使用阶段的好处，例如减少排放和降低维修费用，都有充分的记录，但它们往往被高具体化的能源和不发达的回收基础设施所抵消。现有的LCA研究强调了气候影响，而对人类毒性、资源枯竭和循环等各种指标的反映不足。方法上的限制，如通用数据集、缺乏基于性能的功能单元和简化的EoL建模，损害了可比性。机械回收通常会产生低质量的产品，降低性能，限制了高价值应用的重复使用，而热和化学方法则面临着能源和可扩展性方面的挑战。未来的工作必须优先考虑标准化的LCA方法、特定区域的背景数据集、循环经济整合和先进的回收技术，以实现FRP的全部可持续性潜力。有必要制定一个战略框架，使FRP作为一种可行的低碳替代品，在未来实现净零排放。

The global climate crisis has intensified efforts to quantify and mitigate the carbon footprint of power transmission and distribution equipment, critical components of energy infrastructure. This review systematically analyzes the methodologies, standards, and applications for calculating the carbon footprint of this equipment, clarifying the sector's vital role in global decarbonization. The paper elaborates on the theoretical foundation centered on Life Cycle Assessment (LCA), which defines a "cradle-to-grave" system boundary and explores various accounting methods, including process-based analysis, input-output analysis, and hybrid models. For key equipment like transformers, analysis consistently shows the operational phase, driven by energy losses, is the primary source of the carbon footprint, accounting for over 90 % of total life cycle emissions. Consequently, core mitigation strategies focus on enhancing energy efficiency with advanced materials and implementing circular economy models. The review further examines development trends, emphasizing the potential of digital technologies like IoT and AI for real-time carbon accounting. However, significant obstacles persist, including a lack of harmonized standards, difficulties in supply chain data integration, and the challenge of incorporating market mechanisms like carbon pricing. In summary, advancing calculation technologies and strengthening industry collaboration are crucial for achieving carbon accountability and facilitating a sustainable energy transition.

全球气候危机加大了对能源基础设施的关键组成部分——输配电设备的碳足迹进行量化和减轻的努力。本文系统地分析了计算该设备碳足迹的方法、标准和应用，阐明了该部门在全球脱碳中的重要作用。本文以生命周期评估（LCA）为核心，阐述了其理论基础，定义了“从摇篮到坟墓”的系统边界，并探索了基于过程的分析、投入产出分析和混合模型等多种核算方法。对于变压器等关键设备，分析一致表明，由能量损失驱动的运行阶段是碳足迹的主要来源，占总生命周期排放量的90%以上。因此，核心缓解战略侧重于利用先进材料提高能源效率和实施循环经济模式。该报告进一步研究了发展趋势，强调了物联网和人工智能等数字技术在实时碳核算方面的潜力。然而，重大障碍依然存在，包括缺乏统一标准、供应链数据整合困难以及纳入碳定价等市场机制的挑战。总之，推进计算技术和加强行业合作对于实现碳问责制和促进可持续能源转型至关重要。

The transition to a circular economy (CE) is essential for achieving sustainability goals by minimizing waste, optimizing resource use, and extending product lifecycles. Digital Technologies (DTs) serve as key enablers of this transition, facilitating automation, data-driven decision-making, and continuous improvement in CE. However, current notions of smart and digital circularity often focus on technological functionalities without explicitly addressing how DTs can act as means to enable CE solutions that then support sustainable development. This conceptual gap calls for a more integrated approach that aligns CE, digitalization, and sustainability outcomes. This paper systematically reviews the literature at the intersection of DTs and CE, identifying emerging themes and research opportunities. 76 peer-reviewed publications were identified and reviewed based on the DTs applications supporting CE adoption. The findings identify six main research themes, including DTs applications in CE adoption, enablers and barriers to CE adoption with the support of DTs applications, frameworks and models towards a digital CE, business models leveraging digital DTs to support CE, research propositions on DTs applications supporting CE, and DTs applications as solutions to CE adoption throughout product lifecycle. This study also introduces the concept of ‘intelligent circular,’ that integrates circularity, digitalization, and intelligence as the future direction of CE. Eleven research opportunities are proposed including emphasis on the need for empirical evidence, impact evaluation, performance measurement, and system-based approaches. Finally, the paper provides a foundation for advancing the CE transition to intelligent circular, contributing to the development of sustainable, data-driven, and resilient industrial systems.

通过减少浪费、优化资源利用和延长产品生命周期，向循环经济（CE）过渡对于实现可持续发展目标至关重要。数字技术（dt）是这一转变的关键推动者，促进了自动化、数据驱动的决策和CE的持续改进。然而，目前智能和数字循环的概念往往侧重于技术功能，而没有明确解决dt如何作为实现CE解决方案的手段，从而支持可持续发展。这种概念上的差距要求我们采取更加综合的方法，将节能、数字化和可持续性成果结合起来。本文系统地回顾了交互式教学和交互式教学交叉领域的文献，确定了新兴的主题和研究机会。根据支持采用CE的DTs应用程序，确定和审查了76份同行评议出版物。研究结果确定了六个主要的研究主题，包括电子产品采用中的电子产品应用、电子产品采用的推动因素和障碍、数字电子产品采用的框架和模型、利用数字电子产品支持电子产品的商业模式、支持电子产品的电子产品应用的研究主张、电子产品应用作为整个产品生命周期中电子产品采用的解决方案。本研究还介绍了“智能循环”的概念，该概念将循环、数字化和智能作为CE的未来方向。提出了11个研究机会，包括强调对经验证据的需求，影响评估，绩效测量和基于系统的方法。最后，本文为推进CE向智能循环过渡提供了基础，为可持续、数据驱动和弹性工业系统的发展做出了贡献。

The circular economy seeks to preserve resource value by promoting circular business models (CBMs) such as repair, reuse, remanufacturing, and recycling. However, the practical operationalization of cascading – where resources are sequentially utilized across multiple CBMs to maximize their residual value – remains insufficiently explored, particularly in the textile and clothing (T&C) industry. This sector, marked by high resource consumption, short product lifespans, and significant environmental impacts, presents unique opportunities to slow resource loops and enhance value creation. This study systematically reviews 45 academic articles to examine how cascading is operationalized within the T&C sector. Seven archetypes of cascading are identified, encompassing interactions within and between inner loops (e.g., rental, repair, reuse), outer loops (e.g., remaking, recycling), and open-loop applications across value chains. Using cascade chain theory, these practices are mapped onto four guiding principles: appropriate fit, augmentation, consecutive relinking, and balancing resource metabolism. The analysis reveals key enabling factors for effective cascading, including advanced sorting technologies, digital and physical tracking systems, circular design, life extension strategies, supply chain coordination, supportive policies, eco-material substitution, and innovative recycling techniques. Despite these enablers, scaling cascading operations is hindered by infrastructural limitations, market and safety challenges, insufficient local processing capacity, and regulatory barriers. The findings highlight critical factors shaping cascading practices and emphasize the need for coordinated action among T&C stakeholders, policymakers, and intermediaries to establish robust cascade chains and advance the transition to circularity.

循环经济寻求通过促进循环商业模式（CBMs），如维修、再利用、再制造和回收，来保护资源价值。然而，级联的实际操作-在多个信任措施中依次利用资源以最大化其剩余价值-仍然没有得到充分探索，特别是在纺织和服装行业。该行业的特点是资源消耗高、产品寿命短、环境影响大，为减缓资源循环和提高价值创造提供了独特的机会。本研究系统地回顾了45篇学术论文，以研究级联是如何在科技部门运作的。确定了七个级联原型，包括内部循环（例如，租赁，维修，再利用），外部循环（例如，重新制造，回收）和跨价值链的开环应用之间的相互作用。利用级联链理论，这些实践被映射到四个指导原则：适当的匹配，增强，连续重链接和平衡资源代谢。分析揭示了有效级联的关键促成因素，包括先进的分类技术、数字和物理跟踪系统、循环设计、延长寿命策略、供应链协调、支持政策、生态材料替代和创新的回收技术。尽管有这些促成因素，但基础设施限制、市场和安全挑战、本地处理能力不足以及监管障碍阻碍了级联作业的扩展。研究结果强调了形成级联实践的关键因素，并强调需要在t&&c利益相关者、政策制定者和中介机构之间协调行动，以建立健全的级联链并推进向循环过渡。

The growing demand for lithium-ion batteries (LIBs) highlights the need for efficient lithium recovery. Developing cost-effective, environmentally friendly extraction methods from secondary sources, such as end-of-life (EoL) Li-ion batteries, is essential for a sustainable lithium supply chain. This study optimizes Li₂CO₃ recovery, ensuring battery-grade quality, seamless integration into cathode active material (CAM) synthesis, and economic feasibility within hydrometallurgical recycling. Two approaches for single-stage Li recovery in a hydrometallurgical process with integrated CAM production from black mass of lithium nickel manganese cobalt oxide (NMC) LIBs are compared: homogeneous precipitation with Na₂CO₃ and heterogeneous precipitation using CO₂ gas. The analysis focuses on process efficiency, Li purity, and suitability for battery applications. Results show that selective CO₂-based precipitation demonstrated higher selectivity, achieving 97.10 % Li recovery (recoverable as Li₂CO₃), compared to 77.97 % for Na₂CO₃ precipitation, with both methods yielding battery-grade purity and morphology. Recycled NMC622 cathodes synthesized from recovered Li₂CO₃ achieved over 95 % of the discharge capacity of those from commercial Li₂CO₃. Recycled materials demonstrated excellent capacity retention and high coulombic efficiency (∼100 %) after 30 cycles. Full-scale modeling assessed economic and environmental impacts in European LIBs recycling scenarios. Heterogeneous precipitation showed higher profitability (+0.73 M€/year) and greater net GHG reduction (986 t CO₂/year) but was more energy price-sensitive. Homogeneous precipitation demonstrated stable profitability (+0.62 M€/year); however, reduction in GHG emissions was more limited, reaching 518 t CO₂/year. This study integrates lithium recovery and water reclamation into a closed-loop process, enabling direct NMC cathode production, offering a sustainable and economically viable solution for LIBs manufacturing.

对锂离子电池（LIBs）日益增长的需求凸显了对高效锂回收的需求。从二次资源（如报废锂离子电池）中开发成本效益高、环境友好的提取方法，对于可持续发展的锂供应链至关重要。本研究优化了Li2CO3回收，确保了电池级质量，无缝集成到阴极活性材料（CAM）合成中，并在湿法冶金回收中具有经济可行性。比较了湿法冶金一体化CAM生产镍锰钴酸锂（NMC）黑质锂单阶段锂回收的两种方法：Na2CO3均相沉淀法和CO2气体非均相沉淀法。分析的重点是工艺效率、锂纯度和电池应用的适用性。结果表明，选择性co2基沉淀具有更高的选择性，锂回收率为97.10%（可回收为Li2CO3），而Na2CO3沉淀为77.97%，两种方法均可获得电池级纯度和形貌。利用回收的Li2CO3合成的NMC622阴极的放电容量达到了商用Li2CO3阴极的95%以上。经过30次循环后，再生材料表现出优异的容量保持和高库仑效率（~ 100%）。全尺寸模型评估了欧洲lib回收方案的经济和环境影响。非均匀降水表现出更高的盈利能力（+0.73亿欧元/年）和更大的温室气体净减排（986吨二氧化碳/年），但对能源价格更敏感。均匀降水表现出稳定的盈利能力（+0.62万欧元/年）；然而，温室气体排放量的减少较为有限，仅为518 t CO2/年。该研究将锂回收和水回收整合到一个闭环过程中，实现了直接的NMC阴极生产，为锂离子电池制造提供了一个可持续的、经济上可行的解决方案。

The influence of rural digital economy growth on agricultural carbon emissions is yet unknown as a new driver of rural development. This study uses Spatial Durbin and Mediation models to examine how rural digital economy development (RDED) affected agricultural carbon emissions (ACE) across 261 prefecture-level Chinese cities between 2018 and 2020. The paper also looks at how green innovation and agricultural mechanization (AME) affect agricultural carbon emissions. The results show that (1) RDED significantly increases ACE in localized areas by 19.2 % but decreases ACE in neighboring areas by 10.8 %. (2) At this stage, RDED increases ACE by increasing the level of AME; at the same time, although it promotes the level of green innovation, lower share of green innovation would also have a positive correlation with ACE. (3) The impact of RDED on ACE is more pronounced in western regions and regions with higher levels of digital infrastructure input.

作为农村发展的新动力，农村数字经济增长对农业碳排放的影响尚不清楚。本研究利用空间德宾模型和中介模型，考察了2018 - 2020年中国261个地级市农村数字经济发展对农业碳排放的影响。本文还研究了绿色创新和农业机械化对农业碳排放的影响。结果表明：(1)RDED显著提高了局部区域的ACE，提高了19.2%，但降低了周边区域的ACE，降低了10.8%。(2)在这一阶段，RDED通过提高AME水平来增加ACE；同时，绿色创新份额的降低虽然促进了绿色创新水平，但也与ACE呈正相关。(3)西部地区和数字基础设施投入水平较高的地区，RDED对ACE的影响更为明显。

Enforced carbonation of recycled concrete paste (RCP) presents a promising solution for carbon capture and utilization (CCU) in the cement and construction industries. By transforming concrete waste into a reactive pozzolan while sequestering CO₂, enforced carbonation addresses major environmental challenges and aligns with the circular economy concept in the cement and concrete sector. This review contextualizes the impact of enforced carbonation on heavy metals in RCP to ensure sustainable and ecological compatibility of both the process and the final product, carbonated RCP (cRCP). It summarizes current knowledge on heavy metals in cement and proposes hypotheses on their plausible immobilization mechanisms in enforced-carbonated materials. The review highlights gaps in the literature concerning the impact of carbonation on heavy metals in cement, underscoring the necessity of exploring novel approaches for assessing the heavy metal behaviors from RCP to cRCP.

再生混凝土膏体（RCP）的强制碳化为水泥和建筑行业的碳捕获和利用（CCU）提供了一个有前途的解决方案。通过将混凝土废料转化为活性火山灰，同时封存二氧化碳，强制碳化解决了主要的环境挑战，并符合水泥和混凝土行业的循环经济概念。本文综述了强制碳化对RCP中重金属的影响，以确保过程和最终产品碳化RCP （cRCP）的可持续性和生态兼容性。它总结了目前对水泥中重金属的认识，并提出了关于它们在强制碳化材料中的合理固定机制的假设。这篇综述强调了关于碳酸化对水泥中重金属影响的文献空白，强调了探索新的方法来评估从RCP到cRCP的重金属行为的必要性。
