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。

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.

Water, recognised as a scarce resource, has been considered for sustainable development goals (SDG-6) and acknowledged 2018–2028 as the water action decade. Water is essential for the construction industry, and it consumes around 15–16 % of the global freshwater. While water is directly utilised for construction, for instance, in preparation of mortar, an enormous quantity of water is indirectly consumed through building materials, energy sources, etc. The combination of direct and indirect water components is termed Embodied Water (EW). Minimising EW throughout the building life cycle is imperative to drive towards sustainable development. However, EW has not yet received its due recognition as an essential element in evaluating the sustainability of the building life cycle, with limited research studies addressing its significance. Thus, this paper aims to analyse the contemporary status, barriers, strategies, research trends, and future directions of EW within the building life cycle. The systematic literature review approach was adopted to attain the aim of this paper. The results of this study reveal twenty-two barriers hindering the reduction of EW and twenty-eight strategies to overcome them. Frequent usage of high water-consuming materials, water and material wastage, and difficulties in estimating EW are some of the main barriers identified in this study. Selecting materials with low EW, effective and efficient usage of materials and machinery, and introducing water management-related policies are some of the key strategies derived from this research. Additionally, this paper presents nine research trends and fifteen prospective research avenues identified through existing studies.

水被认为是一种稀缺资源，已被纳入可持续发展目标（可持续发展目标6），并被确认为2018-2028年的水行动十年。水对建筑行业至关重要，它消耗了全球约15 - 16%的淡水。虽然水直接用于建筑，例如制备砂浆，但大量的水通过建筑材料、能源等间接消耗。直接和间接水成分的结合被称为具身水（EW）。在整个建筑生命周期内尽量减少环境污染，是推动可持续发展的必要条件。然而，EW作为评估建筑生命周期可持续性的基本要素尚未得到应有的认可，针对其重要性的研究有限。因此，本文旨在分析建筑生命周期内电子战的现状、障碍、策略、研究趋势和未来方向。为了达到本文的目的，本文采用了系统的文献综述法。本研究的结果揭示了22个阻碍电子商务减少的障碍和28个克服这些障碍的策略。高耗水材料的频繁使用、水和材料的浪费以及难以估计EW是本研究确定的一些主要障碍。选择具有低EW的材料，有效和高效地使用材料和机械，以及引入与水管理相关的政策是本研究得出的一些关键策略。此外，本文还提出了通过现有研究确定的9个研究趋势和15个前瞻性研究途径。

Improving solid waste management (SWM) can better public health locally and mitigate climate change globally. However, it requires thorough financing and business models. This study assessed the willingness to pay (WTP) of four stakeholder groups in the village Cape Maclear, Malawi, using the double-bounded dichotomous choice contingent valuation method as well as direct questions. Households (N

=

259) would be willing to pay an average of MWK 1507 (USD 0.90) per month if they did not have to separate their waste themselves, as opposed to MWK 899 (USD 0.54) per month if they had to separate their waste at the collection point. Lodges were willing to pay USD 13.00 per month for their own waste management and an additional USD 4.22 for public waste removal. The WTP of businesses was assumed to be zero due to an unrepresentative sample. Tourists were found to have an average WTP of USD 1.75 per day.

改善固体废物管理可以改善地方公共卫生，减缓全球气候变化。然而，这需要彻底的融资和商业模式。本研究评估了马拉维麦克利尔角村四个利益相关者群体的支付意愿（WTP），采用双界二分类选择或有估值法以及直接问题。259户家庭如果不需要自己分类垃圾，每月平均愿意支付1507新西兰元（0.90美元），而如果他们必须在收集点分类垃圾，每月平均愿意支付899新西兰元（0.54美元）。旅馆愿意为自己的废物管理每月支付13.00美元，为公共废物清除额外支付4.22美元。由于样本不具代表性，假设企业的WTP为零。游客平均每天的WTP为1.75美元。我们建议基于系统的所有成本和收入流的可持续商业模式。因此，游客显示出最大的潜力。尽管如此，建议使系统的每月运行独立于外部来源，但将这些来源用于长期投资和基础设施改进。

Textile blends are challenging to recycle due to usage of multiple different blend percentages, but also due to composition change caused by fiber degradation over time. This is particularly crucial for workwear, which must meet strict performance and safety requirements. This paper discusses estimating blend composition changes using near infrared hyperspectral imaging. We analyzed 30 used hospital workwear garments with known number of laundering cycles and identical polyester-cotton blend composition at production. A latent variable regression model, based on hyperspectral data, estimated their current composition, which was determined using ISO-standardized chemical analysis. Results showed that near infrared hyperspectral imaging accurately estimated composition changes, with a root mean squared error below 0.5 wt-%, compared to over 1.4 wt-% error when utilizing the number of laundering cycles for estimation. Our approach could be used as a quality control method in sorting, leading to more granular sorted fractions, facilitating increased workwear recycling rates.

由于使用多种不同的混纺百分比，而且由于纤维随时间降解而引起的成分变化，纺织混纺物的回收具有挑战性。这对于工作服尤其重要，因为它必须满足严格的性能和安全要求。本文讨论了利用近红外高光谱成像估计混合成分变化的方法。我们分析了30件已知洗涤次数和相同涤棉混纺成分的医院工作服。基于高光谱数据的潜变量回归模型估计了它们的当前成分，这是通过iso标准化化学分析确定的。结果表明，近红外高光谱成像准确地估计了成分的变化，其均方根误差低于0.5 wt-%，而使用洗涤周期数进行估计时的误差超过1.4 wt-%。我们的方法可以用作分拣的质量控制方法，导致更颗粒的分拣分数，促进提高工作服的回收率。

Under the operation of circular economy to tackle the waste crisis in Australia, there is an imperative call for boosting consumers’ recycling shopping behaviour. Part of the process lies in recyclable packaging and how consumers make purchase decisions based on these types of packaging’s information. Despite the urgency, how consumers process and respond to recyclable packaging cues – the very communication of packaging recyclability, including packaging materials, colour, and recycling signs remains equivocal in both literature and practice. The paper proposed an integrated framework by combining the Elaboration Likelihood Model and Theory of Planned Behaviour, in which the motivations and outcomes of both central and peripheral routes of processing these cues on recyclable packaging were explored, examining how each processing route would result in differentiated influences on purchasing intention. This is considered within the context of fast-moving consumer goods. Using Structural Equation Modelling and AMOS 29 software, the research confirmed the sole effect of the central route on attitudinal change through semiotic knowledge as a new construct and mediator, addressing the limitations of the Elaboration Likelihood Model and the issue of the circular economy in consumers’ dimensions. Recommendations were proposed to manufacturers in retail environments and policymakers towards enhancing consumers’ knowledge of recycling signs for circular economy. Through the introduction of semiotic knowledge, the research makes crucial theoretical contributions to addressing packaging waste by extending the two models and provides scholars and practitioners with an understanding of the implications involved and how they can assist in achieving a circular economy.

在循环经济的运作下解决澳大利亚的垃圾危机，促进消费者的回收购物行为势在必行。这个过程的一部分在于可回收的包装，以及消费者如何根据这些包装类型的信息做出购买决定。尽管迫在眉睫，消费者如何处理和回应可回收的包装线索-包装可回收性的沟通，包括包装材料，颜色和回收标志，在文献和实践中仍然模棱两可。本文结合精化可能性模型和计划行为理论提出了一个综合框架，其中探讨了处理这些可回收包装线索的中心和外围路线的动机和结果，考察了每种处理路线如何对购买意愿产生不同的影响。这是在快速消费品的背景下考虑的。利用结构方程模型和AMOS 29软件，研究通过符号学知识作为一种新的结构和中介，证实了中心路径对态度变化的唯一影响，解决了精化似然模型的局限性和循环经济在消费者维度上的问题。向零售环境中的制造商和政策制定者提出建议，以提高消费者对循环经济回收标志的认识。通过引入符号学知识，该研究通过扩展这两个模型，为解决包装废弃物做出了重要的理论贡献，并为学者和实践者提供了对所涉及的含义的理解，以及他们如何帮助实现循环经济。

Developing novel circular feed from plant-based biomass unfit for direct human consumption is imperative to mitigate environmental degradation. In this study, we tested a sequential fermentation strategy to treat wheat straw (WS) and preserve fresh fruit and vegetable (FFV) discards in making circular feed for ruminants. First, ground wheat straw (particle size <20 mm) moisturized (moisture content 70–80 % by weight) by pure water and by FFV were treated with feed grade fungal strains Tramates versicolor (TV) and Pleurotus ostreatus (PO) at 28 °C for six weeks. Fungal treated mixture resulted in reduced lignin content by 35–55 % and decreased lignin-to-cellulose ratio. Each fungal treated biomass was then mixed with additional FFV and anaerobically fermented at 28 °C for 16 days. Organic acids (over 80 % was lactic acid) accounted for 9–10 % dry matter of the substrates and lowered pH from 5 to about 3.5, which is adequate for preservation of the fermented feed. In vitro dry matter digestibility was not different between the standard diet and sustainability-plus diets that contained 10 % or 25 % of the double-fermented circular feed materials. Fungal fermentation coupled with bacteria-based ensiling of under-valued or wasted biomass can produce novel feeds to support sustainable dairy farming.

从不适合人类直接消费的植物性生物质中开发新型循环饲料是缓解环境退化的必要条件。在本研究中，我们试验了一种顺序发酵策略，用于处理麦秸（WS）和保存新鲜果蔬（FFV）废弃物，制作反刍动物循环饲料。首先，用纯净水和FFV润湿（水分含量占重量的70 - 80%）的磨碎的麦秸（粒径20 mm），在28℃条件下用饲料级真菌菌株versicolor Tramates （TV）和Pleurotus ostreatus （PO）处理6周。真菌处理后的混合物木质素含量降低35 ~ 55%，木质素/纤维素比降低。然后将每个真菌处理过的生物量与额外的FFV混合，并在28°C厌氧发酵16天。有机酸（超过80%是乳酸）占底物干物质的9 - 10%，并将pH从5降低到3.5左右，足以保存发酵饲料。体外干物质消化率在标准饲粮和添加10%或25%双发酵循环饲料的可持续性+饲粮中无显著差异。真菌发酵结合以细菌为基础的青贮被低估或浪费的生物质可以生产新的饲料，以支持可持续的奶牛养殖。
