Shifting economic sectors to a resource-efficient economy with zero net greenhouse gas emissions by 2050 faces major challenges for the European Union, which is highly dependent on material imports. Critical raw materials play a key role in a wide range of emerging technologies. In times of increasing demand, the assessment of critical raw materials is therefore of utmost importance. This study addresses methodological principles of various materials criticality indicators on product-level. Using the example of manufacturing different electrolysis and fuel cell stacks, these criticality indicators are applied, and the results are discussed. The case study demonstrated that alkaline electrolysis has the lowest criticality among the electrolyzers in seven out of nine criticality indicator evaluations. For fuel cells, the heavier stack concept shows lower criticality compared to the light-weight concept. One reason is the higher demand of rare earth elements and cobalt needed for manufacturing compared to heavier stack. Various rare earths are identified as critical in the manufacture of solid oxide electrolysis and fuel cell stacks. Iridium and nickel contribute most to criticality in the construction of proton exchange membrane electrolysis and alkaline electrolysis stacks, respectively. Five of nine indicators point to the same or similar criticality hotspots and can therefore set priorities for action in materials research for hydrogen and fuel cell systems. Nevertheless, when deciding for or against a material, one has to be aware that the criticality indicators use different sensitive sub-indicators which have an impact on the ranking of materials.

对于高度依赖材料进口的欧盟来说，到2050年将经济部门转变为资源节约型经济，实现零温室气体净排放，将面临重大挑战。关键原材料在广泛的新兴技术中发挥着关键作用。在需求不断增长的时代，对关键原材料的评估是至关重要的。本研究在产品层面探讨各种材料临界性指标的方法学原则。以制造不同的电解堆和燃料电池堆为例，对这些临界指标进行了应用，并对结果进行了讨论。案例研究表明，在9项临界指标评价中，碱性电解在7项指标中临界性最低。对于燃料电池来说，较重的电池组概念比轻的电池组概念具有更低的临界性。其中一个原因是与较重的堆栈相比，制造所需的稀土元素和钴的需求更高。各种稀土被认为是制造固体氧化物电解和燃料电池堆的关键。在质子交换膜电解和碱性电解堆的构建中，铱和镍分别是最关键的元素。9个指标中有5个指向相同或相似的临界热点，因此可以确定氢和燃料电池系统材料研究的优先行动。然而，在决定支持或反对一种材料时，必须意识到临界指标使用了不同的敏感子指标，这些子指标会影响材料的排名。

Automobile technology is improving, enabling the development of electric vehicles, which are expected to replace traditional combustion-powered vehicles. The study explores the role of perceived benefits, policy interventions, public opinions, knowledge, and awareness toward using and buying electric vehicles. 434 random responses were analyzed about their intention. The study uses public opinion and awareness as mediating variables towards adopting electric vehicles with an advanced, “two-staged structural equation modelling-artificial neural network” technique. Findings suggest that the public's opinion, policy interventions, perceived benefits, and perceived risk are significantly related to buying electric vehicles. The sample includes 55.76 % male and 44.24 % female respondents. 30 % are postgraduate, 78 % are single, and 80 % live in urban. The findings will be essential for manufacturers and policymakers to formulate and implement strategies to boost electric vehicle market penetration. Based on the result, the study discussed the practical and managerial implications of adopting electric vehicles in an emerging market and provided suggestions for future directions.

Optimising rainwater harvesting (RWH) systems’ design involves sizing the storage and catchment areas to enhance cost-effectiveness, self-sufficiency, and water quality indicators. This paper considers the design of RWH systems under long-term uncertainty in precipitation and demands. In this work, we formulate and solve a multi-objective stochastic optimisation problem that allows explicit trade-offs under uncertainty, maximising system efficiency and minimising deployment cost. We use the yield after spillage (YAS) approach to incorporate the physical and operational constraints and the big-M method to reformulate the nonlinear minmax rules of this approach as a mixed-integer linear programming (MILP) problem. By posing a risk averseness measure on efficiency as a conditional value at risk (CVaR) formulation, we guarantee the designer against the highest demand and driest weather conditions. We then exploit the lexicographic method to effectively solve the multi-objective stochastic problem as a sequence of equivalent single-objective problems. A detailed case study of a botanical garden in Amsterdam demonstrates the framework’s practical application; we show significant improvements in system efficiency of up to 15.5% and 28.9% in the driest scenarios under risk-neutral and risk-averse conditions, respectively, compared to deterministic approaches. The findings highlight the importance of taking into account multiple objectives and uncertainties when designing RWH systems, allowing designers to optimise efficiency and costs based on their specific requirements without extensive parameterisation.

优化雨水收集（RWH）系统的设计包括确定存储和集水区的大小，以提高成本效益、自给自足和水质指标。本文考虑了在降水和需求长期不确定性条件下的水冷供水系统设计问题。在这项工作中，我们制定并解决了一个多目标随机优化问题，该问题允许在不确定性下进行明确的权衡，最大化系统效率和最小化部署成本。我们使用溢出后产量（YAS）方法来结合物理和操作约束，并使用大m方法将该方法的非线性最小最大规则重新表述为混合整数线性规划（MILP）问题。通过将效率的风险规避度量作为条件风险值（CVaR）公式，我们保证设计师不受最高需求和最干燥天气条件的影响。然后，我们利用词典法将多目标随机问题有效地求解为一系列等效的单目标问题。阿姆斯特丹植物园的详细案例研究展示了该框架的实际应用；我们发现，与确定性方法相比，在风险中性和风险厌恶条件下，在最干旱的情况下，系统效率分别提高了15.5%和28.9%。研究结果强调了在设计RWH系统时考虑多个目标和不确定性的重要性，使设计人员能够根据他们的特定要求优化效率和成本，而无需大量参数化。

The waste management sector requires specialized systems analysis tools to facilitate decision-making and make waste management sustainable and efficient. While integrated systemic approaches exist for assessing conventional waste management systems, the integration of emerging technologies such as gasification, pyrolysis, and methane dry reforming remains largely overlooked. In this work, these three technologies have been integrated into a conventional regional waste management model by abstracting rigorous simulation models into machine-learning surrogate models. The resulting technology-rich waste management model incorporates material flow analysis and life-cycle assessment as tools for supporting policy and decision-making. The model was tested by assessing the environmental impacts and landfill rates for three technology implementation scenarios. Overall, the inclusion of these emerging technologies led to an environmental performance improvement compared to a reference system. For example, a 116.5 % reduction of the carbon footprint in the most optimistic scenario. Nevertheless, the mere addition of these technologies was not enough to achieve landfill rates below 10 %, reaching 37.6 % in the most optimistic scenario. Therefore, properly sizing capacity was found to be a key factor in minimizing both environmental impact and landfill rate.

废物管理部门需要专门的系统分析工具来促进决策，并使废物管理具有可持续性和高效性。虽然已有评估传统废物管理系统的综合系统方法，但气化、热解和甲烷干重整等新兴技术的整合在很大程度上仍被忽视。在这项工作中，通过将严格的模拟模型抽象为机器学习代用模型，将这三种技术整合到传统的区域废物管理模型中。由此产生的技术丰富的废物管理模型将物料流分析和生命周期评估作为支持政策和决策的工具。通过评估三种技术实施方案的环境影响和垃圾填埋率，对模型进行了测试。总体而言，与参考系统相比，纳入这些新兴技术可改善环境绩效。例如，在最乐观的情况下，碳足迹减少了 116.5%。然而，仅仅增加这些技术还不足以使垃圾填埋率低于 10%，在最乐观的情况下，填埋率达到 37.6%。因此，适当确定处理能力是将环境影响和填埋率降到最低的关键因素。

The global expansion of solar energy presents a paradox: while it is a key sustainable technology, a comprehensive waste management strategy for decommissioned solar panels remains insufficient. Previous studies have examined this issue, yet waste volume estimations remain incomplete due to the exclusion of early waste streams and the failure to account for temporal fluctuations in key variables. This study addresses these gaps by employing System Dynamics Modelling (SDM) to capture a more nuanced understanding of the heterogeneity of decommissioned panels. The findings reveal significant discrepancies between projections from conventional static models and those generated by the developed model, underscoring the need for more adaptive forecasting methods that account for temporal variations and the evolving characteristics of decommissioned panels. Furthermore, this paper highlights the inefficiencies of uniform waste management approaches, emphasizing the need for differentiated strategies based on panel characteristics. Crucially, the findings challenge the recycling-centric paradigm by exposing the overlooked potential of functional discarded panels, advocating for circular strategies that prioritize reuse and secondary markets.

太阳能的全球扩张呈现出一个悖论：虽然它是一项关键的可持续技术，但对退役太阳能电池板的全面废物管理战略仍然不足。以前的研究已经审查了这一问题，但由于排除了早期废物流和未能考虑关键变量的时间波动，对废物量的估计仍然不完整。本研究通过采用系统动力学建模（SDM）来更细致地了解退役面板的异质性，从而解决了这些差距。研究结果显示，传统静态模式的预估与已开发模式的预估之间存在重大差异，强调需要更有适应性的预测方法，以考虑到时间变化和退役面板的演变特征。此外，本文强调了统一废物管理方法的低效率，强调了基于面板特征的差异化策略的必要性。至关重要的是，研究结果通过揭示功能性废弃面板被忽视的潜力，挑战了以回收为中心的范式，倡导优先考虑再利用和二级市场的循环战略。

Rare earth elements (REEs) are known for their specialized optical and electronic properties that have led to their use in a wide range of applications, such as luminescent fibers employed in security papers (e.g., bank notes). Most of the security documents are disposed at the end of their life, losing the raw materials. Considering REEs are listed as critical raw materials, adoption of sustainable recycling and circular economy practices are imperative for ensuring supply chains in the future and aligning with United Nations sustainable development goals. In this contribution, a recycling method consisting of leaching and solvent extraction-based separation for recovering REEs from luminescent fibers is presented. An optimization of the separation method for extracting the metals of interest (Er, Y, La, Gd, Yb, Ho, Tm, Tb, and Eu) was carried out by assessing selective extractants (di-(2-ethylhexyl) phosphoric acid (HDEHP) and N-methyl-N,N,N-trioctylammonium chloride (Al336)), the ligand concentration and the acid concentration. The former showed high selectivity and extractive performance for most of the heavy REEs (>95 %) by using the HDEHP ligand (1.0 mol/L) and adjusting the acid concentration of the aqueous solution at 0.01 mol/L with hydrochloric acid. The developed extractive metallurgy process was applied to doped REE cellulose fibers after performing a digestion, showing impressive extraction profiles in most cases (>80 %). The solvent separation method presented in this work can be employed for other classes of doped fibers after a proper optimization process and can make security fiber industry circular with its resources use.

稀土元素（ree）以其特殊的光学和电子特性而闻名，这使得它们在广泛的应用中得到了应用，例如用于防伪纸（例如，纸币）的发光纤维。大多数安全文件在其使用寿命结束时被处理掉，失去了原材料。考虑到稀土元素被列为关键原材料，采用可持续回收和循环经济实践对于确保未来的供应链并与联合国可持续发展目标保持一致至关重要。本文提出了一种由浸出和溶剂萃取分离组成的从发光纤维中回收稀土元素的回收方法。通过对选择性萃取剂（二-（2-乙基己基）磷酸（HDEHP）和N-甲基-N，N，N-三辛基氯化铵（Al336））、配体浓度和酸浓度的评价，对提取目的金属（Er， Y, La, Gd, Yb, Ho, Tm， Tb和Eu）的分离方法进行了优化。前者采用HDEHP配体（1.0 mol/L）和盐酸调节水溶液的酸浓度为0.01 mol/L，对大多数重稀土元素（> 95%）具有较高的选择性和萃取性能。在进行消化后，将开发的萃取冶金工艺应用于掺杂稀土纤维素纤维，在大多数情况下显示出令人印象深刻的萃取曲线（> 80%）。本研究提出的溶剂分离方法经过适当的优化处理，可用于其他类型的掺杂纤维，并可使安全纤维工业实现资源循环利用。

Manufacturers worldwide depend on supply chains for raw material inputs and intermediate products, with varying importance and risk levels across countries and supply chain stages. Understanding these variations is essential for developing strategies to mitigate supply chain vulnerabilities. This study adds a geographic dimension to the existing criticality assessment framework by simultaneously comparing material criticality in China, the European Union (EU), Japan, and the United States (US). It assesses supply chain risk (two stages: mining, processing) and economic importance for twelve materials representing infrastructure, battery, specialty, and other materials. Our analysis reveals distinct regional differences: China faces greater supply risk at the mining stage, primarily due to its reliance on imported raw materials for certain minerals, while the United States experiences higher supply risk at the processing stage, stemming from limited domestic processing capabilities. The EU and Japan exhibit higher supply risks overall than both the US and China, largely because of limited domestic production capacities. Japan has the highest number of materials—eight out of twelve—with both high supply risk and economic importance. Materials with the greatest difference in criticality among regions are rare-earths and aluminum at the processing stage, where processing bottlenecks and concentration of processing facilities heighten supply risks, and lithium, nickel, and cobalt at the mining stage, due to geographic concentration of mining activities and rising demand driven by battery production. These findings highlight the necessity for region-specific strategies to address supply chain risks, such as diversifying import sources, investing in mining/processing infrastructure, and stockpiling.

世界各地的制造商依赖于原材料投入和中间产品的供应链，不同国家和供应链阶段的重要性和风险水平各不相同。了解这些变化对于制定减轻供应链脆弱性的战略至关重要。本研究通过同时比较中国、欧盟（EU）、日本和美国的材料临界性，为现有的临界性评估框架增加了地理维度。它评估了12种材料的供应链风险（两个阶段：采矿、加工）和经济重要性，这些材料包括基础设施、电池、特种材料和其他材料。我们的分析显示了明显的区域差异：中国在采矿阶段面临更大的供应风险，主要是由于某些矿物依赖进口原材料，而美国在加工阶段面临更高的供应风险，这是由于国内加工能力有限。总体而言，欧盟和日本的供应风险高于美国和中国，这在很大程度上是因为国内生产能力有限。日本拥有最多的稀土原料——12种中有8种——供应风险和经济重要性都很高。区域间临界差异最大的材料是处于加工阶段的稀土和铝，加工瓶颈和加工设施的集中加剧了供应风险；以及处于采矿阶段的锂、镍和钴，这是由于采矿活动的地理集中和电池生产推动的需求上升。这些研究结果突出表明，有必要制定针对特定区域的战略来应对供应链风险，例如使进口来源多样化、投资于采矿/加工基础设施以及储备。

To address challenges of municipal food waste (FW) treatment and urban green space (UGS) soil simultaneously, this study proposes the "Residential FW - Decentralized Composting - Application to UGS" (DCUGS) supply chain and assess its sustainability performances. A Mixed-Integer Linear Programming model integrated with GIS (Geo-Information System) at a fine-scale was set up to simulate this conceptual chain in Haidian, Beijing. The sustainability performance of the supply chain is then assessed across economic, environmental, and social dimensions. The results indicated that compost fulfills 61% of residential and 12% of park green space fertilizer needs, with 51% of FW processed locally. Compared to centralized FW management, DCUGS costs 254.21 CNY/ton, 18.04% of centralized treatment costs, mainly due to reduced transportation. Carbon footprint (CF) analysis indicates DCUGS also achieves a carbon reduction of 64.11 kg CO_2e/ton, surpassing mainstream Chinese FW management. A hedonic model reveals that the increase in residents’ welfare from enhanced greenery outweighs the space occupied by composting facilities. All results show this chain exhibits superior sustainability across three dimensions and may provide a sustainable and preferable choice for the resourceful treatment of FW in Chinese cities.

为了同时解决城市食物垃圾（FW）处理和城市绿地（UGS）土壤的挑战，本研究提出了“住宅食物垃圾-分散堆肥-应用于UGS”（DCUGS）供应链，并评估其可持续性绩效。以北京海淀区为例，建立了一个与GIS （Geo-Information System）相结合的精细尺度混合整数线性规划模型来模拟这一概念链。然后从经济、环境和社会三个方面对供应链的可持续性绩效进行评估。结果表明，堆肥满足了61%的住宅和12%的公园绿地肥料需求，其中51%的FW在当地处理。与FW集中管理相比，DCUGS成本为254.21元/吨，为集中处理成本的18.04%，主要原因是运输减少。碳足迹（CF）分析表明，DCUGS还实现了64.11 kg CO2e/吨的碳减排，超过了中国主流FW管理。一个享乐模型显示，增强绿化带来的居民福利的增加超过了堆肥设施所占用的空间。研究结果表明，该链条在三个维度上具有良好的可持续性，可以为中国城市FW的资源化治理提供可持续的、较好的选择。

The increasing and continuous generation of water treatment plant sludge (WTPS) is still an under-recognised problem, although in most countries the inappropriate disposal of WTPS into watercourses has a negative impact on the environment. The need to incorporate circular economic principles in the management of this waste has stimulated studies on the reintroduction of WTPS into the production chain, but these investigations generally evaluate specific processes. The aim of this research was to identify the potential and limitations of WTPS reuse. Therefore, a systematic literature review was carried out using the archival search method, which resulted in the analysis of 106 selected articles. The results show that the beneficial use of WTPS in the manufacture of construction products and as inputs for chemical processes are the most studied applications. This can be explained by sludge's composition that consists of more than 80% by mass of the elements: silicon, aluminum, iron and calcium. It should be noted that the predominance of these elements is related to the type of input used in water purification and the characteristics of the raw water collected. The mineralogical composition of WTPS is seasonally predominated by quartz and kaolinite. These residues also contain heavy metals especially such as barium, chrome, lead and mercury, and microorganisms such as proteobacteria, firmicutes and cyanobacteria, presenting potential risks to human health and the environment, and demanding special care in the management and beneficial uses. The lack of standardization and studies that address environmental and economic viability are research gaps in this area.

水处理厂污泥的不断增加和不断产生仍然是一个未得到充分认识的问题，尽管在大多数国家，将水处理厂污泥不当处置到水道中对环境产生了负面影响。需要将循环经济原则纳入这种废物的管理，这刺激了关于将WTPS重新引入生产链的研究，但这些调查一般评价具体过程。本研究的目的是确定WTPS重用的潜力和局限性。因此，我们采用文献检索法进行了系统的文献综述，筛选出106篇文章进行分析。研究结果表明，WTPS在建筑产品制造和化学工艺投入中的有益利用是研究最多的应用。这可以用污泥的成分来解释，它由超过80%的元素组成：硅、铝、铁和钙。应该指出的是，这些因素的优势与水净化中使用的投入类型和收集的原水的特性有关。WTPS的矿物组成以石英和高岭石为主。这些残留物还含有重金属，特别是钡、铬、铅和汞，以及变形菌门、厚壁菌门和蓝藻门等微生物，对人类健康和环境构成潜在风险，在管理和有益利用方面需要特别小心。缺乏标准化和研究解决环境和经济可行性是这一领域的研究空白。
