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.

Urban areas in the Global South continue to face persistent municipal solid waste (MSW) management challenges driven by rapid urbanization, informal disposal practices, and limited monitoring capacity. This study assesses the operational feasibility of integrating unmanned aerial vehicle (UAV) imagery with YOLOv7 object detection to identify improperly discarded plastic bags in public spaces across Metropolitan Lima, Peru. A total of 370 high-resolution aerial images from three districts were processed to detect black, yellow, and white bags, representative of local disposal behaviors. The model achieved a recall of 33 %, precision of 34 %, and a mean average precision ([email protected]) of 21.3 % at an operational point corresponding to a confidence threshold of 0.24, reflecting the challenges posed by data scarcity and high visual heterogeneity in the urban environment. Although performance was constrained by class imbalance and low inter-class contrast, detections remained adaptable to diverse urban conditions through threshold tuning. UAV-based detection provides spatially explicit data to prioritize cleanup operations, verify citizen reports, and optimize waste collection routes. This proof of concept demonstrates that UAV-assisted monitoring can complement municipal records and support incremental improvements in sanitation logistics within resource-limited urban contexts.

由于快速的城市化、非正式的处置做法和有限的监测能力，全球南方的城市地区继续面临城市固体废物管理方面的持续挑战。本研究评估了将无人机（UAV）图像与YOLOv7目标检测相结合的操作可行性，以识别秘鲁利马大都会公共场所不当丢弃的塑料袋。对来自三个地区的370张高分辨率航空图像进行处理，检测代表当地处置行为的黑色、黄色和白色塑料袋。该模型在对应于0.24的置信阈值的操作点上实现了33%的召回率，34%的精度和21.3%的平均精度（[email protected]），反映了城市环境中数据稀缺性和高度视觉异质性带来的挑战。尽管性能受到类别不平衡和低类别间对比度的限制，但通过阈值调优，检测仍然能够适应不同的城市条件。基于无人机的检测提供空间明确的数据，以确定清理行动的优先顺序，验证公民报告，并优化废物收集路线。这一概念验证表明，无人机辅助监测可以补充市政记录，并支持在资源有限的城市环境中逐步改善卫生后勤。

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。

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。

Food consumption has shown to represent an important fraction of GHG emissions in most countries worldwide. However, food consumption behavior is highly heterogeneous and depends on numerous variables, including affordability and availability of different food categories and products. The main objective of the current study was to analyze changes in GHG emissions linked to Peruvian dietary patterns and analyze their geographical and temporal variability, using household survey data for the period 2008–2022. From a methodological standpoint, the model estimated apparent household food consumption, as well as food away from home, food obtained from charities, and food loss and waste quantification, to provide an in-depth depiction of Peruvian diets. Diets were then estimated based on geographical location, socioeconomic groups, and the Peruvian average diet. Results show that GHG emissions have remained stable during the period analyzed (1126 kg CO₂eq/person/year on average), with a peak attained in 2014 (1236 kg CO₂eq/person/year) after years of economic growth and substantial decreases in the poverty rate. Thereafter, carbon emissions have dwindled based on increasing poverty levels, and a gradual substitution of beef for chicken meat, although heterogeneous patterns can be observed among regions. It was estimated that by 2022 an additional 1401 kt CO₂eq per year would be emitted to guarantee that those living in poverty or extreme poverty conditions reach daily minimum caloric requirements. The uncertainty of the results, a comparison of these to those of other countries around the world, and potential improvement actions to attain healthier low carbon emission diets are also discussed.

在世界上大多数国家，粮食消费占温室气体排放的重要部分。然而，食品消费行为是高度异质性的，取决于许多变量，包括不同食品类别和产品的可负担性和可获得性。本研究的主要目的是利用2008-2022年家庭调查数据，分析与秘鲁饮食模式相关的温室气体排放变化，并分析其地理和时间变异性。从方法的角度来看，该模型估计了明显的家庭粮食消费，以及离家食物、从慈善机构获得的食物、粮食损失和浪费的量化，以提供对秘鲁饮食的深入描述。然后根据地理位置、社会经济群体和秘鲁的平均饮食来估计饮食。结果表明，在分析期间，温室气体排放量保持稳定（平均1126 kg CO2eq/人/年），经过多年的经济增长和贫困率大幅下降，在2014年达到峰值（1236 kg CO2eq/人/年）。此后，随着贫困水平的提高，以及牛肉逐渐取代鸡肉，碳排放量有所减少，尽管在不同地区之间可以观察到不同的模式。据估计，到2022年，每年将额外排放1401千吨二氧化碳当量，以保证生活在贫困或极端贫困条件下的人达到每日最低热量需求。结果的不确定性，与世界其他国家的比较，以及实现更健康的低碳排放饮食的潜在改进行动也进行了讨论。

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。

Perspectives from the broken electronics repair system: Barriers and enablers along the repair journey 从损坏的电子维修系统的角度看：维修过程中的障碍和推动因素

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。

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.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"29 ","pages":"Article 200304"},"PeriodicalIF":6.4,"publicationDate":"2025-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145924757","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}

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。
