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。

The construction industry is a significant driver of resource consumption and waste generation, particularly through construction and demolition waste (CDW). Circular economy (CE) principles, which emphasize recycling and material reuse, offer a sustainable approach to CDW management, although achieving market viability for recycled CDW products remains complex. This study undertakes a systematic literature analysis of CDW market development within a CE framework, combining bibliometric analysis and critical review to identify key market dynamics, stakeholder roles, regulatory challenges, and innovative business models. The findings reveal persistent barriers, including fragmented regulations, inconsistent standards, and economic constraints, particularly in regions with inadequate recycling infrastructure. To address these challenges, this study proposes the Circular Market Strategic Framework for CDW (CMSF-CDW), aligning policy harmonization, financial incentives, advanced recycling technologies, and stakeholder collaboration to foster resilient and scalable markets for recycled CDW materials. The study emphasizes the need for region-specific policies, scalable digital tools, and further efforts on CE implementation to enhance resource efficiency and drive market growth. Key findings highlight the central role of public-private partnerships in aligning market incentives with regulatory goals, the importance of digital traceability tools in building trust and material transparency, the effectiveness of green procurement and certification schemes in accelerating demand for recycled CDW products, and the need to align performance-based standards with procurement protocols to create stronger market signals and investor confidence. By offering these insights, the study supports policymakers, industry leaders, and researchers in advancing sustainable construction practices and accelerating the circular transition in the built environment.

建造业是消耗资源和产生废物的重要驱动力，尤其是建筑和拆卸废物。循环经济（CE）原则强调循环利用和材料再利用，为CDW管理提供了一种可持续的方法，尽管实现再生CDW产品的市场可行性仍然很复杂。本研究在CE框架下对CDW市场发展进行了系统的文献分析，结合文献计量分析和批判性回顾，以确定关键的市场动态、利益相关者角色、监管挑战和创新的商业模式。调查结果揭示了持续存在的障碍，包括法规分散、标准不一致和经济限制，特别是在回收基础设施不足的地区。为了应对这些挑战，本研究提出了CDW循环市场战略框架（CMSF-CDW），将政策协调、财政激励、先进的回收技术和利益相关者合作结合起来，促进CDW回收材料的弹性和可扩展市场。该研究强调需要制定针对特定地区的政策、可扩展的数字工具，并进一步努力实施节能减排，以提高资源效率并推动市场增长。主要研究结果强调了公私伙伴关系在使市场激励与监管目标保持一致方面的核心作用，数字可追溯工具在建立信任和材料透明度方面的重要性，绿色采购和认证计划在加速对再生CDW产品的需求方面的有效性，以及将基于绩效的标准与采购协议结合起来以创造更强的市场信号和投资者信心的必要性。通过提供这些见解，该研究支持政策制定者、行业领导者和研究人员推进可持续建筑实践，加速建筑环境的循环过渡。

Quantifying food loss and waste (FLW) is a priority on the international agenda, as it is essential to establish effective prevention and reduction measures for FLW generation. Nevertheless, FLW data remain inconsistent, making it challenging to compare data across sectors, monitor long-term trends and thus set attainable prevention targets, specifically aligning with SDG12.3 of the UN Sustainable Development Agenda. With the mandatory food waste accounting in the European Union (EU), accurate FLW quantification becomes relevant. In this study, a systematic literature review of FLW quantification research within the EU agri-food chain was done. The information was synthesised and coded to identify definitional and methodological differences across studies and common FLW quantification frameworks – the Food Loss and Waste Accounting and Reporting Standard and the EU delegated decision 2019/1597. In addition, limitations outlined in the studies were synthesised to identify aspects limiting the credibility of the quantification procedure and applicability of the FLW data. Our findings indicate significant variability in research methods, representativity and scope across studies. Results show that food service and households are the most studied stages of the food supply chain, with questionnaires being the most used method. Unrepresentative sample, lack of accurate data and self-reporting error emerged as major limitations in the analysed studies. Studies also highlight economic and environmental considerations beyond mass estimates of FLW, and consideration of the agricultural production (pre-harvest/pre-slaughter and harvest/slaughter) stage in FLW quantification. This study provides insights into overlooked aspects and potential advances in FLW quantification research for broader impact beyond mandatory reporting.

量化粮食损失和浪费（FLW）是国际议程上的一个优先事项，因为建立有效的预防和减少FLW产生的措施至关重要。然而，儿童死亡率数据仍然不一致，这使得比较各部门数据、监测长期趋势、从而制定可实现的预防目标（特别是与联合国可持续发展议程的可持续发展目标12.3相一致）具有挑战性。随着欧盟（EU）强制性的食物浪费核算，准确的FLW量化变得相关。本研究对欧盟农业食品链内FLW量化研究进行了系统的文献综述。对这些信息进行了综合和编码，以确定研究和常见FLW量化框架（粮食损失和浪费会计和报告标准以及欧盟授权决定2019/1597）之间的定义和方法差异。此外，综合了研究中概述的局限性，以确定限制量化程序可信度和FLW数据适用性的方面。我们的研究结果表明，研究方法、代表性和研究范围存在显著差异。结果表明，食品服务和家庭是食品供应链中研究最多的阶段，问卷调查是使用最多的方法。不具代表性的样本、缺乏准确的数据和自我报告错误成为分析研究的主要局限性。研究还强调了在FLW的大量估计之外的经济和环境考虑，以及在FLW量化中考虑农业生产（收获前/屠宰前和收获/屠宰）阶段。本研究提供了对FLW量化研究中被忽视的方面和潜在进展的见解，以产生比强制性报告更广泛的影响。

The information was synthesised and coded to identify definitional and methodological differences across studies and common FLW quantification frameworks – the Food Loss and Waste Accounting and Reporting Standard and the EU delegated decision 2019/1597. In addition, limitations outlined in the studies were synthesised to identify aspects limiting the credibility of the quantification procedure and applicability of the FLW data. Our findings indicate significant variability in research methods, representativity and scope across studies. Results show that food service and households are the most studied stages of the food supply chain, with questionnaires being the most used method. Unrepresentative sample, lack of accurate data and self-reporting error emerged as major limitations in the analysed studies. Studies also highlight economic and environmental considerations beyond mass estimates of FLW, and consideration of the agricultural production (pre-harvest/pre-slaughter and harvest/slaughter) stage in FLW quantification. This study provides insights into overlooked aspects and potential advances in FLW quantification research for broader impact beyond mandatory reporting.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"28 ","pages":"Article 200287"},"PeriodicalIF":6.4,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145097813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To support the transition to circular economy (CE), companies are called to develop and implement CE initiatives through CE strategies. To be effective, CE capabilities are required, defined as appropriate skills, knowledge, abilities, organizational processes, and routines needed to develop CE strategies. This paper investigates two relevant issues concerning the assessment of CE capabilities possessed by country’s companies and the identification suitable CE strategies to be adopted for different economic sectors. We adopt the economic complexity and develop two assessment schemes: the Country Circular Economy Capability Space, assessing the CE capabilities of countries’ companies, and the Circular Economy Capability Proximity Matrix, identifying effective CE strategies to implement by companies in different industries. To build our assessment schemes, we use the multi-regional input‐output tables provided by EXIOBASE3. Based on indices designed, our analyses offer a clear picture of CE capabilities possessed by countries and suggest which CE strategies to adopt for supporting the effective CE transition of economic industries.

为了支持向循环经济（CE）的过渡，公司被要求通过CE战略制定和实施CE倡议。要想有效，就需要CE能力，定义为开发CE战略所需的适当技能、知识、能力、组织流程和惯例。本文研究了评估国家企业的环保能力和确定适合不同经济部门的环保战略两个相关问题。我们采用经济复杂性并开发了两种评估方案：国家循环经济能力空间，评估各国公司的环保能力；循环经济能力接近矩阵，确定不同行业公司实施的有效环保战略。为了构建我们的评估方案，我们使用了EXIOBASE3提供的多区域投入产出表。基于设计的指数，我们的分析提供了各国拥有的CE能力的清晰图景，并建议采取哪些CE战略来支持经济产业的有效CE转型。

Agri-food supply chains generate significant waste, yet adopting side-stream valorization to improve sustainability is not straightforward due to conflicting stakeholder objectives. Existing research often overlooks how divergent economic and environmental priorities among key actors, such as farmers and processors, inhibit the design and implementation of effective valorization strategies. This study addresses this gap by investigating these conflicts within the Dutch potato and coffee supply chains using a mixed-methods approach that integrates qualitative surveys and the Analytic Hierarchy Process. Potato farmers strongly favored economic goals over environmental ones, prioritizing primary sales revenue and soil quality, which led to composting and feed pathways. In contrast, processors adopted a more balanced perspective, focusing on profit, by-product revenue, and energy and water efficiency, favoring food ingredient pathways. Coffee growers and processors assigned similar weight to economic and environmental domains but differed significantly on specific objectives, such as raw material cost versus subsidies and soil quality versus wastewater demand. These differences influenced their distinct approaches to food ingredient valorization. Our findings demonstrate that actor-specific priorities critically shape valorization pathway selection and overall supply chain configuration. This research contributes an actor-centric analysis to delineate these conflicts, providing valuable insights for developing tailored policies and collaborative strategies that align diverse interests and enhance the potential of sustainable side-stream valorization in agri-food supply chains.

农业食品供应链产生了大量的浪费，但由于利益相关者的目标相互冲突，采用侧流增值来提高可持续性并不是直截了当的。现有的研究往往忽略了关键行为者（如农民和加工者）之间不同的经济和环境优先事项如何抑制有效定价战略的设计和实施。本研究通过使用综合定性调查和层次分析法的混合方法调查荷兰马铃薯和咖啡供应链中的这些冲突，解决了这一差距。马铃薯种植者强烈支持经济目标而不是环境目标，优先考虑主要销售收入和土壤质量，这导致了堆肥和饲料途径。相比之下，加工商采取了更平衡的观点，关注利润、副产品收入、能源和水的效率，倾向于食品成分的途径。咖啡种植者和加工商对经济和环境领域的重视程度相似，但在具体目标上存在显著差异，例如原材料成本与补贴、土壤质量与废水需求。这些差异影响了他们对食品成分增值的独特方法。我们的研究结果表明，特定行为者的优先级对定价路径选择和整体供应链配置至关重要。本研究对这些冲突进行了以行为者为中心的分析，为制定有针对性的政策和合作战略提供了有价值的见解，这些政策和合作战略可以协调不同的利益，并增强农业食品供应链中可持续侧流增值的潜力。

The increasing accumulation of bio-waste poses significant environmental challenges worldwide. Sustainable and effective resource management is essential to restore ecosystems. Activated carbon produced from agricultural biomass through pyrolysis offers a sustainable solution to these issues. Therefore, this study provides detailed insights into the synthesis of activated carbon, highlighting critical parameters affecting the quality by extracting data from 240 published articles. The parametric analysis evaluates variables such as pyrolysis temperature, activation agent, and biomass type that impact the yield and specific surface area (SSA) of the synthesized activated carbon. Key findings reveal that optimizing pyrolysis conditions can enhance both yield and SSA. Furthermore, the paper presents the development of 03 different machine-learning regression models for predicting the performance of engineered biochar production by physical and chemical activation processes. This approach offers a dual benefit of waste reduction and resource efficiency by transforming agricultural waste into high-quality activated carbon. The study lays a foundation for further exploration of innovative applications, data science and advanced production techniques, aiming to make activated biochar production more environmentally friendly and economically viable.
