This article aims to address the limited understanding of business model development in commercializing carbon mineralization (CM) technologies. Existing frameworks broadly describe business models in carbon capture utilisation and storage (CCUS) projects but fail to sufficiently integrate technological scaling requirements and multi-stakeholder value mechanisms integral to CM that shape value propositions, value creation and delivery structures, and value capture strategies, especially the conversion of CO₂ into valuable product. To bridge this gap, we develop a descriptive conceptual framework that links technological aspects of CM, such as process scaling, material transitions, resources requirements, directly shaping business model mechanisms that define how sustainable value is created, delivered, and captured across stakeholders in the value chain. By utilising qualitative thematic analysis with a deductive coding approach within a Finnish industry-academia joint research project, we extend this exploratory conceptual framework. We identify sustainable value created and captured by different stakeholders and identify how resources and capabilities influence value creation processes along the value chain. We further explore how value proposition, value creation and delivery, and value capture, along with key barriers and drivers, influence the adoption of large-scale carbon mineralization. With limited research on CM business model development and a large gap between current R&D and commercialization, the study offers a novel framework providing practical insights for stakeholders and developers to support and accelerate the commercialization of CM technologies.

本文旨在解决在商业化碳矿化（CM）技术中对商业模式开发的有限理解。现有框架广泛地描述了碳捕集利用和封存（CCUS）项目的商业模式，但未能充分整合技术规模要求和多利益相关者价值机制，这些价值机制是CM不可或缺的一部分，形成了价值主张、价值创造和交付结构，以及价值捕获策略，特别是将二氧化碳转化为有价值的产品。为了弥合这一差距，我们开发了一个描述性概念框架，它将CM的技术方面联系起来，例如过程缩放、材料转换、资源需求，直接塑造商业模型机制，定义如何在价值链中的利益相关者之间创建、交付和获取可持续价值。通过在芬兰产学研联合研究项目中使用演绎编码方法的定性专题分析，我们扩展了这一探索性概念框架。我们确定由不同利益相关者创造和获取的可持续价值，并确定资源和能力如何影响价值链上的价值创造过程。我们进一步探讨了价值主张、价值创造和交付、价值获取以及主要障碍和驱动因素如何影响大规模碳矿化的采用。由于对CM商业模型开发的研究有限，以及当前研发和商业化之间的巨大差距，该研究提供了一个新的框架，为利益相关者和开发人员提供了实际的见解，以支持和加速CM技术的商业化。

Electronics repair is a core component of a circular economy, yet the many social, technical, and financial barriers limit the widespread adoption of repair practices along the value chain. The high complexity of electronics, reinforced by product design choices, and a perpetuating culture of consumption has normalised replacement when a fault occurs. Similarly, a lack of technical knowledge, uncertainty of repair outcomes, and opaque repair pricing make electronics repair particularly challenging for repair actors. However, existing literature lacks a comprehensive overview of the barriers and enablers perceived by the actors involved in the repair process, and how they influence the repair journey. To address these gaps, this study conducts a scoping review and interviews to understand the root causes of barriers and enablers of repair. The main barriers identified are the (assumed) affordability of repair services, repair not being front of mind for consumers, and the availability of spare parts, tools, and repair guides. These issues are largely attributed to upstream issues with product design, supplier agreements, and business operations lacking thoughtful construction to enable a smooth repair process. Our findings support the conceptualisation of the repair journey with interconnected barriers and enablers influencing decision-making in each stage. Building on this framework, we also present intervention opportunities for brands and manufacturers to facilitate repair along the repair journey. Future research should be conducted to measure the behavioural outputs of policy interventions designed to incentivise repair.

电子维修是循环经济的核心组成部分，然而许多社会、技术和金融障碍限制了维修实践在价值链上的广泛采用。电子产品的高度复杂性，再加上产品设计的选择，以及一种经久不衰的消费文化，使得故障发生时的更换成为常态。同样，技术知识的缺乏、修理结果的不确定性以及不透明的修理定价使得电子产品修理对修理行为者来说尤其具有挑战性。然而，现有文献缺乏对参与修复过程的参与者感知到的障碍和促进因素的全面概述，以及它们如何影响修复过程。为了解决这些差距，本研究进行了范围审查和访谈，以了解障碍的根源和修复的促成因素。确定的主要障碍是（假定的）维修服务的可负担性，维修不是消费者考虑的首要问题，以及备件、工具和维修指南的可用性。这些问题在很大程度上归因于上游产品设计、供应商协议和业务运营方面的问题，这些问题缺乏深思熟虑的构建，无法确保维修过程的顺利进行。我们的研究结果支持修复过程的概念化，其中相互关联的障碍和促成因素影响每个阶段的决策。在此框架的基础上，我们还为品牌和制造商提供了干预机会，以促进维修过程中的维修。未来的研究应用于衡量旨在激励修复的政策干预的行为产出。

This study represents an initial effort to develop a new product—prefabricated building blocks—through a unique, multifaceted approach that integrates three complementary analyses: physical-mechanical, economic, and environmental. Specifically, we examine six typologies of the new product, incorporating three component types—natural aggregate, recycled concrete, and recycled ceramic—with or without the addition of recycled low-density polyethylene (LDPE). The technical analysis reveals that adding two components (recycled aggregates and LDPE) decreases thermal conductivity and density by 56.8 % and 32.6 %, respectively. Second, mechanical resistance is lower than that of more conventional solutions, suggesting that the new product is suitable for non-structural applications while improving the thermal resistance of construction systems. The economic analysis, using simulation tools (FlexSim), shows that one component decreases the cost per cubic metre and transportation costs per unit, while increasing the break-even time, ultimately shortening the period required to reach profitability. The environmental analysis conducted via life-cycle assessment (LCA) positions products made with one of the components―recycled ceramic aggregate―as the most environmentally friendly, with a 16.8 % reduction in GWP compared to other solutions. Overall, our study highlights the need for future research on the convenience of examining new product development in the construction sector across multiple, yet interdependent, dimensions that reflect real-world decision-making, in which aspects such as technical functionality, cost-effectiveness, and ecological impact are typically assessed together.

这项研究代表了开发一种新产品的初步努力——预制建筑模块——通过一种独特的、多方面的方法，整合了三种互补的分析：物理-机械、经济和环境。具体来说，我们研究了新产品的六种类型，包括三种成分类型-天然骨料，再生混凝土和再生陶瓷-添加或不添加再生低密度聚乙烯（LDPE）。技术分析表明，添加两种组分（再生骨料和LDPE）分别降低了56.8%和32.6%的导热系数和密度。其次，机械阻力低于更常规的解决方案，这表明新产品适用于非结构应用，同时提高了建筑系统的热阻。使用仿真工具（FlexSim）进行的经济分析表明，一个组件降低了每立方米的成本和每单位的运输成本，同时增加了盈亏平衡时间，最终缩短了实现盈利所需的时间。通过生命周期评估（LCA）进行的环境分析表明，使用其中一种成分（回收陶瓷骨料）制造的产品是最环保的，与其他解决方案相比，GWP降低了16.8%。总体而言，我们的研究强调了未来对建筑行业新产品开发的便利性进行研究的必要性，这些便利性跨越多个相互依存的维度，反映了现实世界的决策，其中技术功能、成本效益和生态影响等方面通常被一起评估。

Deposit-refund systems (DRS) are widely recognized as effective instruments of the circular economy, however, their long-term success depends not only on technical design and financial incentives but also on consumer engagement. Empirical research on the psychological drivers of DRS participation remains limited, especially in Central and Eastern Europe, creating a need to understand how attitudes shape behavioral adoption in early-stage systems. This study applies the three-component attitude model, distinguishing cognitive, affective, and conative dimensions, to explain consumer participation in Hungary’s newly introduced national DRS, the REpont scheme. Unlike most previous applications, the model was identified inductively from empirical data through exploratory and confirmatory factor analyses, providing a data-driven theoretical contribution to behavior research. A large-scale survey (n = 2665) was conducted and analyzed using partial least squares structural equation modeling (PLS-SEM). The findings indicate that affective and conative attitudes are strong predictors of system use, while cognitive evaluations exert a moderate but significant effect. For the latter, however, demographic and cluster analyses revealed subgroups (urban, highly educated) with reduced usage despite higher awareness. Emotional commitment strengthens favorable evaluations, which in turn encourage behavioral intentions and routines, confirming the sequential pathway from affect to cognition to conation. From a theoretical perspective, the study extends the attitude model to a novel circular economy context, while from a policy and managerial perspective, it highlights that addressing infrastructural barriers and contextual challenges and strengthening emotional engagement are essential to ensure the long-term effectiveness of DRS.

存款退款系统（DRS）被广泛认为是循环经济的有效工具，然而，它们的长期成功不仅取决于技术设计和财政激励，还取决于消费者的参与。关于DRS参与的心理驱动因素的实证研究仍然有限，特别是在中欧和东欧，因此需要了解态度如何影响早期系统的行为采用。本研究应用三成分态度模型，区分认知、情感和意向维度，来解释消费者参与匈牙利新推出的国家DRS，即REpont计划。与之前的大多数应用不同，该模型是通过探索性和验证性因素分析从经验数据中归纳得出的，为行为研究提供了数据驱动的理论贡献。采用偏最小二乘结构方程模型（PLS-SEM）对2665人进行了大规模调查和分析。研究结果表明，情感态度和意向态度是系统使用的重要预测因子，而认知评价则具有中等但显著的影响。然而，对于后者，人口统计和聚类分析显示，尽管意识较高，但亚群体（城市、受过高等教育）的使用率较低。情感承诺加强了有利评价，而有利评价反过来又促进了行为意图和惯例，从而证实了从情感到认知再到注意的顺序途径。从理论角度来看，该研究将态度模型扩展到新的循环经济背景下，而从政策和管理角度来看，它强调了解决基础设施障碍和环境挑战以及加强情感参与对于确保DRS的长期有效性至关重要。

This research explores how consumer knowledge of date labels influences food waste behavior and associated financial loss, emphasizing the role of individual differences in risk taking and environmental values. Based on a survey of 954 participants from a Canadian population, the study finds that while most consumers understand the distinction between best-before and use-by labels, most consumers still rely heavily on date labels, often discarding edible food due to perceived safety concerns. Importantly, the relationship between label knowledge and waste behavior is shaped by food-related risk taking: This study supported that individuals with higher risk-taking tolerance successfully act on their knowledge of date labels to reduce waste, supporting the hypothesis that risk-taking moderates this effect. Meanwhile, environmental values directly predict lower food waste but do not significantly moderate the effect of knowledge, suggesting that pro-environmental consumers may already follow sustainable food management practices independent of label understanding. The model also confirms that household food waste predicts household financial loss, with an estimated average cost of CAD 246 per year attributable to misinterpreting date labels. These findings underscore the complexity of consumer behavior and the need for targeted interventions. Educational campaigns should be tailored to different risk profiles, and label redesigns should incorporate sensory cues to build confidence in food safety assessments.

本研究探讨了消费者对日期标签的了解如何影响食物浪费行为和相关的经济损失，强调了个体差异在风险承担和环境价值方面的作用。根据对954名加拿大人的调查，这项研究发现，虽然大多数消费者都明白“最佳食用前”标签和“在此之前食用”标签之间的区别，但大多数消费者仍然严重依赖日期标签，经常出于安全考虑而丢弃可食用的食品。重要的是，标签知识和浪费行为之间的关系是由与食物相关的风险承担决定的：这项研究支持具有更高风险容忍能力的个体成功地根据他们对日期标签的知识采取行动来减少浪费，支持了风险承担调节这种影响的假设。同时，环境价值直接预测食物浪费的减少，但不会显著调节知识的影响，这表明亲环境的消费者可能已经遵循了独立于标签理解的可持续食品管理实践。该模型还证实，家庭食物浪费预示着家庭经济损失，据估计，误读日期标签每年造成的平均成本为246加元。这些发现强调了消费者行为的复杂性和有针对性干预的必要性。教育活动应针对不同的风险概况，重新设计标签应纳入感官线索，以建立对食品安全评估的信心。

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。
