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。

The arid regions of Northwest China, as ecologically fragile areas, face significant challenges to urban development and ecological conservation due to water resource limitations. A robust ecological security pattern (ESP) is crucial for sustainable urban growth, yet existing studies often overlook water resource constraints, leaving the varying impacts of these constraints on ESP effectiveness unclear. This study constructed urban ESPs for Zhangye City under different water-constrained scenarios. Results indicate that water constraints enhance ESP performance with diminishing returns; ecological corridors and networks show an inverted U-shaped trend, where corridor length, robustness, connectivity, and efficiency peak under medium constraints. Based on these findings, the study develops an optimal urban ESP under medium water constraints. Policy implications include moderate water management, urban park enhancement, and improved connectivity in southeastern areas via green spaces. This framework supports Zhangye’s sustainable development and is transferable to other arid cities.

西北干旱区作为生态脆弱区，水资源的有限性使其城市发展和生态保护面临重大挑战。健全的生态安全格局对城市可持续发展至关重要，但现有研究往往忽视了水资源约束，使得这些约束对生态安全格局有效性的不同影响尚不清楚。本研究构建了张掖市不同水资源约束情景下的城市可持续发展规划。结果表明，水约束提高了ESP的性能，但收益递减；生态廊道和生态网络在中等约束条件下，廊道长度、稳健性、连通性和效率均呈现倒u型趋势。在此基础上，研究开发了中等水约束条件下的城市ESP优化方案。政策影响包括适度的水资源管理，城市公园的加强，以及通过绿地改善东南地区的连通性。这一框架支持张掖的可持续发展，并可推广到其他干旱城市。

Understanding the generation patterns of municipal solid waste and adapting to it is one of the most urgent problems of the decade, which requires meaningful answers in order to establish sustainable and resilient waste management infrastructures. The purpose of this literature review is to systematize the models and approaches that are suitable for predicting the amount of municipal solid waste (MSW). Based on systematically explored literature analysis (used Scopus database in 2023) methodologies, a recommendation framework is developed to underpin the design of municipal solid waste management systems by recording possible models and proxy variables in addition to presenting their advantages and limitations based on the 78 papers that met the selection criteria. The proposed framework identifies possible model structures according to the municipal solid waste management analysis task and data availability, which fills the gap and lays the foundations for data-based decision support in goal-oriented municipal solid waste management. A total of 36 AI-driven models are explored and catalogued using 455 proxy variables. Depending on the number of observations and the set of available proxy variables, a model structure framework is provided, based on which the identification of models can be optimized for the completion of goal-oriented municipal solid waste predicting tasks. This literature review provides a basis for meeting the goal-oriented MSW modeling tasks at a higher level, as it also proposes a model catalog, data inventory and model structures, and discusses how to address the challenges that may arise for the models. It is the first research to distinguish modeling issues of interest to industry professionals and academics, thereby providing guiding results for the entire municipal solid waste management sector.

The major objective of this study was to assess the correlations of environmental impact indicators along with fundamental consistency and rheological performance of asphalt-rubber binders through multi-objective optimization of crumb rubber (CR) dosages by adopting the lifecycle assessment (LCA) approach. The scope of the effort included: (i) preparation of modified asphalt binder with three CR dosages: 10, 15, and 20% by weight of the base virgin asphalt binder, (ii) fundamental consistency tests to assess the performance of virgin and CR-modified asphalt binder blends, (iii) lifecycle inventory analysis from raw material extraction to the production of CR-modified asphalt binders, (iv) LCA of virgin and CR-modified asphalt binder blends, (v) correlation analysis of CR contents and the corresponding environmental and performance parameters, and (vi) multi-objective optimization of CR dosage to balance the performance enhancement with environmental sustainability. A reinforcement learning approach was implemented in optimizing the CR content in asphalt binder blends by balancing the environmental sustainability and performance objective, which revealed that the asphalt binder blend incorporated with 20% CR demonstrated a favorable balance between the mechanical performance and environmental impacts. It is envisioned that the framework developed in this study will support the strategic reuse of end-of-life tires in high-performance low-carbon pavement systems while also advancing the long-term goals of resource circularity in the context of sustainable infrastructure.

本研究的主要目的是通过采用生命周期评估（LCA）方法对橡胶颗粒（CR）用量进行多目标优化，评估环境影响指标与沥青橡胶粘合剂基本稠度和流变性能的相关性。工作范围包括：(i)制备三种CR用量的改性沥青粘合剂；10%、15%和20%的基础原生沥青粘合剂（按重量计），（ii）评估原生和CR改性沥青粘合剂混合物性能的基本一致性测试，（iii）从原材料提取到CR改性沥青粘合剂生产的生命周期清单分析，（iv）原生和CR改性沥青粘合剂混合物的LCA， (v) CR含量与相应的环境和性能参数的相关性分析。(6) CR投加量的多目标优化，以平衡性能提升与环境可持续性。采用强化学习方法，通过平衡环境可持续性和性能目标来优化沥青混合料中CR的含量，结果表明，加入20% CR的沥青混合料在力学性能和环境影响之间取得了良好的平衡。预计本研究中开发的框架将支持高性能低碳路面系统中报废轮胎的战略再利用，同时在可持续基础设施的背景下推进资源循环的长期目标。

The pulp and paper industry (P&PI) plays a critical role in the global economy, supplying essential products for education, packaging, and hygiene. Despite its importance, the P&PI ranks among the top five energy-intensive industries, consuming nearly 6% of global industrial energy and contributing about 2% of total CO₂ emissions. This review provides a comprehensive assessment of the sector’s carbon footprint, focusing on Scope 1, Scope 2, and Scope 3 emissions. It highlights the challenges posed by energy-intensive operations and complex value chains, emphasizing the urgency of aligning with global net-zero targets. Opportunities for reducing Scope 1 and Scope 2 emissions include innovations in combined heat-and-power (CHP) systems, recovery-boiler optimization, and enhanced process efficiency. Scope 3 emissions, spanning raw-material sourcing, logistics, and product end-of-life, require improved data transparency, supplier engagement, and standardized reporting. Strategies such as automated environmental data management, eco-friendly product design, and circular business models are identified as critical for addressing indirect emissions. The review concludes by outlining a roadmap for decarbonizing the industry through technological innovation, digital traceability, and collaborative industrial ecosystems capable of accelerating the transition toward sustainable, net-zero pulp and paper production.

纸浆和造纸工业（P&；PI）在全球经济中起着至关重要的作用，为教育、包装和卫生提供必要的产品。尽管它很重要，但P& PI是五大能源密集型行业之一，消耗了全球近6%的工业能源，贡献了约2%的二氧化碳排放总量。本审查对该行业的碳足迹进行了全面评估，重点关注范围1、范围2和范围3的排放。报告强调了能源密集型运营和复杂价值链带来的挑战，强调了与全球净零排放目标保持一致的紧迫性。减少范围1和范围2排放的机会包括热电联产（CHP）系统的创新、回收锅炉优化和提高工艺效率。范围3的排放，包括原材料采购、物流和产品报废，需要提高数据透明度、供应商参与和标准化报告。自动化环境数据管理、环保产品设计和循环商业模式等战略被认为是解决间接排放问题的关键。最后，该审查概述了通过技术创新、数字可追溯性和协作工业生态系统来实现行业脱碳的路线图，这些生态系统能够加速向可持续、净零纸浆和纸张生产的过渡。

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。

Mainstreaming green products from industrial symbiosis: Does environmental knowledge affect consumers' perceptions and behavioral intentions? 产业共生中的绿色产品主流化：环境知识是否影响消费者的认知和行为意图？

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。

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.

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 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。

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。
