This study introduces mechanochemical activation–instantaneous carbon thermal shock (CTS) as a synergistic strategy for the high-value utilization of all components in retired crystalline-Si photovoltaic (PV) modules, addressing recycling bottlenecks such as limited metal recovery, high chemical consumption, and low-value treatment of Si. Mechanochemical ball milling effectively disrupts the Ag–Si interface and glassy interlayers, increasing the specific surface area and inducing lattice distortions. This lowers the reaction activation energy, enabling high leaching efficiencies for Ag (99.5%) and Al (94%) while markedly reducing the required nitric acid dosage. Subsequent CTS, with its ultrafast heating, overcomes the kinetic limitations of silica reduction, rapidly converting the acid-leached Si residue into high-purity, highly crystalline SiC. The synthesized SiC is well suited for high-temperature electronic devices and thermal management applications due to its excellent thermal stability, high thermal conductivity, and semiconducting properties. Life cycle and economic analyses indicate that, compared with conventional hydrometallurgical methods, the proposed process reduces the environmental footprint by 88.19% and lowers material treatment costs, offering an economically viable pathway for green, closed-loop recycling of PV waste.

本研究介绍了机械化学活化-瞬时碳热冲击（CTS）作为一种协同策略，用于退役晶体硅光伏（PV）模块中所有组件的高价值利用，解决回收瓶颈，如有限的金属回收，高化学消耗和低价值Si处理。机械化学球磨有效地破坏了Ag-Si界面和玻璃化夹层，增加了比表面积并引起晶格畸变。这降低了反应活化能，使银（99.5%）和铝（94%）的浸出效率高，同时显著减少所需的硝酸用量。随后的CTS凭借其超快加热，克服了二氧化硅还原的动力学限制，将酸浸后的硅渣快速转化为高纯度、高结晶的SiC。由于其优异的热稳定性、高导热性和半导体特性，合成的SiC非常适合于高温电子器件和热管理应用。生命周期和经济分析表明，与传统的湿法冶金方法相比，该工艺减少了88.19%的环境足迹，降低了材料处理成本，为光伏废弃物的绿色闭环回收提供了一条经济可行的途径。

Textile waste from ‘fast fashion’ has considerable environmental impact and is an EU priority area. Colonising textiles with fungi provides a unique solution, with options to bond them together to create composite materials, fruit them to provide mushrooms (source of chitin-glucan complex), or both. We produced mycelium-textile composites in analogy to traditional prepreg-based composite manufacturing, consolidating multiple textile stacks colonised with Ganoderma lucidum into a single material of customisable thickness and free-form geometry. An oxygen gradient existed through the cross-section of textile stacks, resulting in more growth on surface than core plies. Consolidated composites comprising only surface layers achieved tensile strengths up to ∼14 MPa. Their flexural and shear strengths (7 MPa and 0.5 MPa, respectively) indicated suitability for semi-structural construction applications. Waste textile substrate could also be fruited (5.7% w/w yield). These advances expand the stalled application of mycelium composites and provide a nature-based solution to textile upcycling.

来自“快时尚”的纺织废料对环境有相当大的影响，是欧盟的优先领域。用真菌在纺织品上定居提供了一种独特的解决方案，可以选择将它们粘合在一起以制造复合材料，或者将它们果实制成蘑菇（几丁质-葡聚糖复合物的来源），或者两者兼而有之。我们生产了菌丝纺织复合材料，类似于传统的基于预浸料的复合材料制造，将多种纺织材料与灵芝结合成一种可定制厚度和自由几何形状的材料。氧梯度通过纺织堆的横截面存在，导致表面比芯层生长更多。仅包含表层的固结复合材料的抗拉强度可达~ 14 MPa。它们的抗折和抗剪强度（分别为7 MPa和0.5 MPa）表明适合半结构施工应用。废纺织基质也可以得到果实（5.7% w/w产率）。这些进展扩大了停滞不前的菌丝复合材料的应用，并为纺织品升级回收提供了一种基于自然的解决方案。

Current sustainability assessments for contaminated site remediation lack unified frameworks integrating multidimensional impacts and public input, alongside data-supported weighting methods. We developed a methodology coupling life cycle assessment (LCA) with sustainability matrices, using social media big data to derive public perception-based weights. Environmental, social, and economic dimensions were weighted at 73.7%, 19.2%, and 7.1%, respectively, with critical indicators of soil (15.9%), business and local economy (4.7%) and indirect/external costs (4.6%) in each dimension. Applied to a site with metals and total petroleum hydrocarbon (TPH) contamination, environmental impacts dominated sustainability scores despite offsetting social/economic gains. In situ remediation using chemical oxidation and immobilization (net -306) demonstrated significantly lower net impact than ex situ excavation with cement kiln co-disposal (net -355), proving more sustainable. This novel sustainability assessment methodology is transferrable to other contaminated sites for improved efficiency and reduced costs during the decision-making and implementation of green and sustainable remediation (GSR).

目前污染场地修复的可持续性评估缺乏整合多维影响和公众投入的统一框架，以及数据支持的加权方法。我们开发了一种将生命周期评估（LCA）与可持续性矩阵相结合的方法，利用社交媒体大数据得出基于公众感知的权重。环境、社会和经济维度的权重分别为73.7%、19.2%和7.1%，土壤（15.9%）、商业和地方经济（4.7%）和间接/外部成本（4.6%）是每个维度的关键指标。应用于金属和总石油烃（TPH）污染的场地，尽管抵消了社会/经济收益，但环境影响主导了可持续性得分。使用化学氧化和固定化的原位修复（净值-306）比水泥窑共同处置的非原位开挖（净值-355）的净影响要低得多，证明更具可持续性。这种新颖的可持续性评估方法可转移到其他污染场地，在绿色和可持续修复（GSR）的决策和实施过程中提高效率和降低成本。

There is an urgent need to decarbonize cement and concrete production. One of the most rapidly implementable strategies is to partially replace Portland cement (PC) in concrete with supplementary cementitious materials (SCMs), such as natural pozzolans (NPs), which are globally abundant but underused. Current studies have focused on only one or a subset of NPs and used inconsistent approaches for estimating their environmental impacts and production costs, hindering the ability to compare these SCMs and determine their best applications. We systematically review NPs—including calcined clays, diatomaceous earth, pumice, scoria, and tuff—to examine both their composition as well as their contributions to fresh and hardened concrete properties. We use a harmonized assessment approach to examine greenhouse gas (GHG) emissions and costs from producing concrete with these NPs, and we concurrently examine experimental results from the review with these emissions and cost findings. Our results show that these NPs can offer necessary composition, improve durability, and offer desired contributions to strength with proper mixture proportioning. On average, NP concretes resulted in 7–24 % GHG emissions reduction, while lowering consumption of the costliest constituent, PC. These results demonstrate that, with appropriate selection and processing, NPs offer a scalable, cost-effective route to partial PC replacement, advancing concrete decarbonization.

目前迫切需要对水泥和混凝土进行脱碳生产。最快速实施的策略之一是用补充胶凝材料（SCMs）部分取代混凝土中的波特兰水泥（PC），例如全球丰富但未充分利用的天然火山灰（NPs）。目前的研究只关注一种或一部分NPs，并且使用了不一致的方法来估计其环境影响和生产成本，从而阻碍了比较这些SCMs并确定其最佳应用的能力。我们系统地回顾了nps——包括煅烧粘土、硅藻土、浮石、矿渣和凝灰岩——来研究它们的组成以及它们对新混凝土和硬化混凝土性能的贡献。我们使用统一的评估方法来检查使用这些NPs生产混凝土的温室气体（GHG）排放和成本，并同时使用这些排放和成本调查结果来检查审查的实验结果。我们的研究结果表明，这些NPs可以提供必要的成分，提高耐久性，并通过适当的混合比例提供所需的强度贡献。平均而言，NP混凝土减少了7 - 24%的温室气体排放，同时降低了最昂贵的成分PC的消耗。这些结果表明，通过适当的选择和处理，NPs为部分PC替代提供了一种可扩展的、具有成本效益的途径，促进了混凝土的脱碳。

Concrete production is a major source of global emissions, and incorporating supplementary cementitious materials (SCMs) offers a pathway to lower carbon construction. This study evaluates the life cycle and cost performance of eight alternative SCMs in Australia: recycled concrete powder (RCP), clay brick powder (CBP), recycled glass powder (RGP), lithium slag powder (LSP), red mud powder (RMP), limestone calcined clay (LC2), steel slag powder (SSP) and pond ash (PA). The study considers 83 mixes containing these SCMs, as reported in the literature, which achieved 30–40 MPa. The results showed that LC2 achieved the lowest GWP (283 kg CO₂-eq/m³; 8.22 kg CO₂-eq/MPa) and the lowest cost (∼133 AU$/m³). RGP and LSP also reduced ADPF to 71–70 MJ/MPa, while RMP and LSP achieved the lowest strength-normalised costs (3.8–3.9 AU$/MPa). CBP and PA performed worse due to poor reactivity and higher costs (>4.3 AU$/MPa). These findings highlight the potential of LC2, RGP, LSP, and RMP to support circular, low-carbon concrete in Australia.

混凝土生产是全球排放的主要来源，添加补充胶凝材料（scm）为低碳建筑提供了一条途径。本研究评估了澳大利亚8种可替代的SCMs的生命周期和性价比：再生混凝土粉（RCP）、粘土砖粉（CBP）、再生玻璃粉（RGP）、锂渣粉（LSP）、赤泥粉（RMP）、石灰石煅烧粘土（LC2）、钢渣粉（SSP）和池塘灰（PA）。据文献报道，该研究考虑了83种含有这些SCMs的混合物，达到30-40 MPa。结果表明，LC2具有最低的GWP （283 kg CO₂-eq/m³；8.22 kg CO₂-eq/MPa）和最低的成本（约133 AU$/m³）。RGP和LSP也将ADPF降低到71-70 MJ/MPa，而RMP和LSP的强度标准化成本最低（3.8-3.9 AU$/MPa）。由于反应性差和成本较高（>；4.3澳元/兆帕），CBP和PA表现较差。这些发现突出了LC2、RGP、LSP和RMP在澳大利亚支持循环低碳混凝土方面的潜力。

This work presents a machine learning-driven methodology for bioplastic formulation design, valorizing eggshell waste as reinforcement. Two bioplastic formulations were developed: bioplastic from Droguería Industrial San Juan starch (BADSJ) and bioplastic from Biopack starch (BAS), reinforced with eggshell powder (ESP). PCA was performed on thickness, moisture, solubility, puncture strength (Ps), deformation at break point (Pd), biodegradability and opacity. Six machine learning algorithms were evaluated. Random Forest ntree = 200 and Linear Support Vector Machine (SVM) achieved the best performance, achieving 83.3% accuracy and 0.81 Kappa. These models estimated concentration ranges associated with improved Ps and Pd. The SVM exhibited higher predictive consistency, with R² of 0.9724 and lower error metrics (RMSE: 0.1422; MAE: 0.1043) compared to Random Forest. SVM predicted broader range of eggshell concentrations (0.47–1.47%) associated with improved Ps and Pd values, indicating better differentiation between formulations. These models provide a data-driven framework for optimizing bioplastic formulations and reducing experimental iterations.

Urban infrastructure is crucial for socio-economic development, yet the link between construction material stocks and societal needs in rapidly growing Global South cities remains insufficiently understood. This study conducts a spatially explicit analysis of Lima, Peru, mapping material stocks for buildings dedicated to shelter, education, healthcare, and collective amenities, and relates them to Decent Living Standard (DLS) thresholds and income levels. Results show that heavily populated, low-income, informal areas accumulate greater material stocks but suffer from poorer access to essential services, driven primarily by population demand. In higher-income zones, per-capita living space becomes more significant. This reveals socio-metabolic inequality, as material-intensive expansion in marginalized neighborhoods does not translate into improved well-being. Service privatization and informality exacerbate unequal access. The study concludes by recommending additional factors for future research to refine the understanding of material stocks and service provision relationships in urban contexts.

城市基础设施对社会经济发展至关重要，但在快速增长的全球南方城市中，建筑材料库存与社会需求之间的联系仍未得到充分认识。本研究对秘鲁利马进行了空间分析，绘制了用于住房、教育、医疗和集体设施的建筑材料储量，并将其与体面生活标准（DLS）阈值和收入水平联系起来。结果表明，人口稠密、低收入、非正规地区积累了更多的物质储备，但主要受人口需求的驱动，获得基本服务的机会较差。在高收入地区，人均居住空间变得更加重要。这揭示了社会代谢的不平等，因为边缘化社区的物质密集型扩张并没有转化为改善的福祉。服务私有化和非正式化加剧了服务获取的不平等。最后，本研究为未来的研究推荐了更多的因素，以完善对城市背景下物质储备和服务提供关系的理解。

Electric vehicles (EVs) require more than double the copper of conventional vehicles and are crucial for meeting net-zero targets for the transport sector. To understand the future of copper supply and the effects of the EV transition, we construct a mine-level optimization model to simulate supply dynamics under a variety of demand and copper recycling scenarios in a net-zero future.

We find large additions of new raw-ore-capacity will be necessary by 2050, ranging from 1958 Mt to 6591 Mt, depending on recycling rates and EV battery size. Our highest demand scenario shows insufficient capacity expansion to meet short-term demand, ore grade decline to 0.41%, and 373 new mine openings by 2050. The best scenario (high recycling rates in all sectors and smaller EV batteries) illustrates a pathway to a more sustainable EV transition: demand is met in all years, ore grade remains at 0.5%, and 87 new mines are required.

电动汽车对铜的需求是传统汽车的两倍多，对于实现交通行业的净零排放目标至关重要。为了了解铜供应的未来和电动汽车转型的影响，我们构建了一个矿山级优化模型，以模拟在净零未来的各种需求和铜回收情景下的供应动态。我们发现，根据回收率和电动汽车电池的大小，到2050年将需要大量增加新的原矿产能，从1958亿吨到6591亿吨不等。我们的最高需求情景显示，到2050年，产能扩张不足以满足短期需求，矿石品位降至0.41%，新开矿山373座。最佳情景（所有行业的高回收率和较小的电动汽车电池）说明了通往更可持续的电动汽车转型的途径：所有年份的需求都得到满足，矿石品位保持在0.5%，需要87个新矿山。

This study introduces a novel methodology for urban litter detection and management by combining enhanced pedestrian inspection with automated visual registry, GPS, and machine learning. To establish the model, the research team collected over 10,000 georeferenced point-of-view (POV) images across three predetermined routes in downtown Santiago, Chile. A pre-trained YOLOv8 deep learning model was successfully utilized to binary classify the presence of litter in each image, achieving a precision of 89.03%. Subsequently, a multivariate logistic regression model quantified the correlation between these detection results and urban contextual variables, such as proximity to non-residential activities and transport hubs. The key finding demonstrates that litter occurrence is significantly more prevalent in areas surrounding metro stations and bus stops, thereby providing empirical data to inform targeted, spatially optimized waste management strategies. This approach offers a scalable, low-cost solution for cities globally, particularly in the Global South.

本研究介绍了一种新的城市垃圾检测和管理方法，该方法将增强的行人检查与自动视觉注册、GPS和机器学习相结合。为了建立该模型，研究小组在智利圣地亚哥市中心的三条预定路线上收集了超过10,000张地理参考点（POV）图像。利用预训练的YOLOv8深度学习模型对每张图像中是否存在凋落物进行二值分类，准确率达到89.03%。随后，一个多元逻辑回归模型量化了这些检测结果与城市环境变量（如与非住宅活动和交通枢纽的接近程度）之间的相关性。关键发现表明，垃圾发生在地铁站和公交车站周围地区更为普遍，从而为有针对性的空间优化垃圾管理策略提供了经验数据。这种方法为全球城市，特别是南半球城市提供了一种可扩展的低成本解决方案。

The rapid growth of global desalination raises concerns over high-salinity brine disposal. Vaterite, a valuable but unstable polymorph of CaCO₃, is difficult to mass-produce. This study reports the first pilot-scale production of high-purity vaterite using actual desalination brine and cement kiln dust. A 1-ton system was built and operated at the SWA-WTIIRA desalination complex in Jubail, Saudi Arabia. Through calcium elution and carbonation, conditions were optimized to achieve ≥95 % vaterite content and sub-3 µm particle size. Controlling carbonation temperature and drying prevented transformation to calcite. The process yielded porous, spherical vaterite particles (>20 m²/g surface area, >98.5 % purity). Techno-economic analysis estimated production costs at $2.5/kg, significantly below commercial pharmaceutical-grade vaterite. These findings demonstrate a scalable, low-cost strategy for valorizing desalination brine and industrial by-products, offering both environmental and economic benefits.

全球海水淡化的快速增长引发了人们对高盐度盐水处理的担忧。碳酸钙₃是一种有价值但不稳定的多晶型，很难大规模生产。本研究报告了首次利用实际海水淡化盐水和水泥窑粉尘中试生产高纯度水晶石。在沙特阿拉伯朱拜勒的SWA-WTIIRA海水淡化厂建造并运行了一个1吨重的系统。通过钙洗脱和碳酸化，优化工艺条件，得到≥95%的水晶石含量和小于3µm的粒径。控制碳酸化温度和干燥可防止方解石的转变。该工艺产生多孔的球形水晶石颗粒（表面积为20 m²/g，纯度为98.5%）。技术经济分析估计生产成本为每公斤2.5美元，大大低于商业制药级杂物矿。这些发现证明了一种可扩展的、低成本的策略，可以使海水淡化盐水和工业副产品增值，同时提供环境和经济效益。
