A solar-driven and autonomous photo-thermoelectrochemical osmotic system (PTECOS) is developed to simultaneously regenerate freshwater and recover high-value metal from wastewater, providing a sustainable approach to global resource scarcity. This system employs a novel g-C₃N₄/TiO₂@CF photoanode that enables water purification and metal recovery without the need for external energy input. The integration of a forward osmosis (FO) membrane ensures continuous water replenishment via evaporation-induced osmotic gradients while effectively suppressing salt accumulation on the photoanode surface. By combining efficient photothermal evaporation with enhanced photoelectrochemical conversion in a unified design, PTECOS significantly outperforms conventional photoelectrochemical osmotic systems. The optimized system achieves an interfacial evaporation rate of 1.32 kg m⁻² h⁻¹ under 100 mW cm⁻² illumination, coupled with an FO water flux of 1.30 L m⁻² h⁻¹. It enables copper recovery at 7.8 mg cm⁻² h⁻¹ and reaches a peak power density of 1448.6 mW m⁻². The purified water satisfies the World Health Organization (WHO) and the United States Environmental Protection Agency (EPA) drinking-water standards for the examined contaminants. Field tests under natural sunlight demonstrate stable day-night operation. By integrating photothermal evaporation, photoelectrochemical processes, and osmotically-driven water transport, PTECOS overcomes the traditional trade-off between evaporation efficiency and salt accumulation, achieving energy-autonomous freshwater regeneration and efficient metal recovery. This versatile platform offers a promising path toward sustainable water-treatment technologies that combine energy self-sufficiency with resource recovery, thereby addressing the pressing challenges of global resource scarcity.

开发了一种太阳能驱动的自主光热电化学渗透系统（PTECOS），可以同时再生淡水和从废水中回收高价值金属，为全球资源短缺提供了一种可持续的方法。该系统采用新型g-C3N4/TiO2@CF光阳极，无需外部能量输入即可实现水净化和金属回收。正向渗透（FO）膜的集成确保通过蒸发诱导的渗透梯度连续补水，同时有效抑制光阳极表面的盐积累。通过将高效的光热蒸发与增强的光电化学转化结合在一起，PTECOS显着优于传统的光电化学渗透系统。优化后的系统在100 mW cm−2光照条件下，界面蒸发速率为1.32 kg m−2 h−1，FO水通量为1.30 L m−2 h−1。它能在7.8 mg cm−2 h−1下回收铜，峰值功率密度达到1448.6 mW m−2。净化后的水符合世界卫生组织（卫生组织）和美国环境保护局（环境保护局）对所检查污染物的饮用水标准。在自然光照下的现场试验表明，该系统昼夜运行稳定。通过整合光热蒸发、光电化学过程和渗透驱动的水输送，PTECOS克服了传统的蒸发效率和盐积累之间的权衡，实现了能源自主的淡水再生和高效的金属回收。这个多功能平台为可持续水处理技术提供了一条有希望的道路，将能源自给自足与资源回收结合起来，从而解决全球资源短缺的紧迫挑战。

In this research, we have investigated 45 mobile phones manufactured between 1998 and 2021. After dismantling, the resulting Printed Circuit Boards (PCBs) have been mechanically processed and homogenised. From each PCB, three sample pellets were created and analysed with a portable X-Ray Fluorescence (pXRF). In addition, a post-hoc calibration was performed to correct element and sample-specific biases. This approach allowed us to analyse a large sample size and to identify element mass value trends over time. The results for precious metals show an average annual decrease -2.49 mg/PCB for Ag, -1.14 mg/PCB for Au, and -0.13 mg/PCB for Pd. By contrast, the concentrations of Cu and Ni were increasing, but due to the decreasing mass of PCBs, the overall trends remained constant. Ultimately, the applied methodological approach was effective for analysing large number of samples and provided unique insights into the material trends across different generations of mobile phones.

在这项研究中，我们调查了1998年至2021年间生产的45部手机。拆解后，得到的印刷电路板（pcb）经过机械加工和均质化。从每个PCB中创建三个样品颗粒，并用便携式x射线荧光（pXRF）进行分析。此外，进行了事后校准以纠正元素和样本特异性偏差。这种方法允许我们分析一个大的样本大小，并确定元素质量值随时间的变化趋势。贵金属的测定结果显示，银的年平均值为-2.49 mg/PCB，金的年平均值为-1.14 mg/PCB，钯的年平均值为-0.13 mg/PCB。相比之下，Cu和Ni的浓度呈上升趋势，但由于pcb质量的下降，总体趋势保持不变。最终，应用方法的方法是有效的分析大量的样本，并提供了独特的见解跨越不同代的手机材料趋势。

Amid escalating climate risks, electric bicycles (e-bikes) are emerging as a prominent low-carbon micromobility option in densely populated cities across China and Southeast Asia. However, their overall decarbonization potential has yet to be systematically and comprehensively quantified. Using a spatially explicit life-cycle assessment, we quantifie the carbon emissions and reduction potential of e-bikes in Chinese cities during 2025–2050. Results show that e-bikes emit 45 g CO₂e per kilometer, with a life-cycle footprint of 576–890 kg CO₂e, which is 48–64 % higher than earlier estimates due to more complete inventories and incorporation of provincial grid-intensity factors. In 2024, China’s e-bike sector generated 32.4 ± 1.3 Mt CO₂e, while reducing 7.4 Mt CO₂e through modal substitution, alongside annual reductions of 36 kt NOₓ and 15 kt SO₂. Looking ahead, strategic integration of e-bikes into urban mobility systems could offset 2.9–5.1 % of China’s urban transport emissions by 2050, underscoring their critical role in decarbonizing urban mobility.

在气候风险不断升级的背景下，在中国和东南亚人口密集的城市，电动自行车（e-bikes）正成为一种突出的低碳微交通选择。然而，它们的整体脱碳潜力尚未得到系统和全面的量化。利用空间显式生命周期评估，我们量化了2025-2050年中国城市电动自行车的碳排放和减排潜力。结果表明，电动自行车每公里排放45克二氧化碳，生命周期足迹为576-890公斤二氧化碳，由于更完整的清单和纳入省级电网强度因素，这比之前的估计高出48 - 64%。2024年，中国电动自行车行业产生了32.4±130万吨二氧化碳排放量，同时通过模式替代减少了740万吨二氧化碳排放量，同时每年减少36万吨NOₓ和15万吨SO₂。展望未来，到2050年，电动自行车与城市交通系统的战略性整合可以抵消中国城市交通排放的2.9% - 5.1%，突显出它们在城市交通脱碳方面的关键作用。

As millions of LFP batteries reach their end of life, the challenge of selectively extracting lithium from industrial blackmass, loaded with impurities, has become a focal point for sustainable innovation in battery recycling. However, industrial-scale LFP recycling remains technically challenging due to the complex composition of real battery waste, including high graphite content, binders, and metallic inclusions that undermine conventional leaching processes. In this research study, a selective, green hydrometallurgical approach tailored for impurity-rich LFP blackmass is presented. Using only trace (“hint of acid”) amounts of formic acid with hydrogen peroxide and two-step leaching, achieving ∼94.5% lithium extraction in the two-step formic acid route, whereas the trace sulfuric acid + H₂O₂ condition delivers the highest selectivity, reaching >95% lithium recovery with negligible iron co-leaching, and producing lithium carbonate as an end product (confirmed by XRD and SEM) without the environmental burden of aggressive reagents or high-temperature treatment. Key to this process is careful control of solution pH and oxidation conditions, allowing a scalable, cost‑effective route to close the loop on LFP materials, and proving that the high‑yield lithium recovery and environmental responsibility can be achieved in the same process.

随着数以百万计的LFP电池寿命的结束，从工业黑质中选择性地提取锂的挑战已经成为电池回收可持续创新的焦点。然而，工业规模的LFP回收在技术上仍然具有挑战性，因为实际电池废物的成分复杂，包括高石墨含量、粘合剂和金属夹杂物，这些都会破坏传统的浸出工艺。在本研究中，提出了一种针对富含杂质的LFP黑质定制的选择性绿色湿法冶金方法。在过氧化氢和两步浸出中仅使用微量（“微量酸”）的甲酸，在两步甲酸路线中实现了~ 94.5%的锂提取，而微量硫酸+ h2o条件具有最高的选择性，在忽略铁共浸出的情况下，锂回收率达到>；95%，最终产品碳酸锂（通过XRD和SEM证实）没有腐蚀性试剂或高温处理的环境负担。该工艺的关键是仔细控制溶液pH值和氧化条件，允许可扩展的，成本有效的路线来闭合LFP材料的循环，并证明在同一过程中可以实现高产量的锂回收和环境责任。

Societies across the globe are simultaneously trying to build much more housing while drastically reducing greenhouse gas emissions. This is precipitating debates about the nature of sustainable housing. ‘Conventional wisdom’ holds that taller buildings are worse for the environment coinciding with longstanding skepticism of height, yet the research and data is often anecdotal or incomplete and contradictory. This paper contributes to the discussion by examining how building height affects embodied emissions for new 5-to-20 storey reinforced concrete residential buildings. We find that while height contributes to embodied emissions, its impact is smaller than slab thickness and design tranches within the studied storey range, which offer more effective opportunities to improve resource productivity, reduce material intensity and associated embodied emissions, without reducing building function. Our findings encourage a shift beyond height-based restrictions, urging designers and policy makers to focus on design decisions to conserve resources, lower emissions, and support circular-economy objectives

全球各地的社会都在努力建造更多的住房，同时大幅减少温室气体排放。这引发了关于可持续住房本质的争论。“传统智慧”认为，较高的建筑对环境更有害，这与长期以来对高度的怀疑相吻合，但研究和数据往往是轶事或不完整和矛盾的。本文通过研究建筑高度如何影响新建5至20层钢筋混凝土住宅的隐含排放来促进讨论。我们发现，虽然高度对隐含排放有贡献，但其影响小于所研究楼层范围内的楼板厚度和设计区段，这为提高资源生产率、降低材料强度和相关隐含排放提供了更有效的机会，而不会降低建筑功能。我们的研究结果鼓励超越以高度为基础的限制，敦促设计师和政策制定者将设计决策的重点放在节约资源、降低排放和支持循环经济目标上

Spent grains, as a by-product of Chinese Baijiu brewing, are increasing with the industrial development of Chinese Baijiu. The resource utilization of spent grains is crucial for the sustainable development of Chinese Baijiu enterprise and the realization of the dual carbon goal. This review firstly introduced the brewing process of solid-state fermented Baijiu, as well as the sources and composition of spent grains. Subsequently, the research progress of main twenty distinct methods for the resource utilization of spent grains was comprehensively summarized and evaluated based on recent studies, and categorized into three aspects: (1) direct utilization methods of nutrients and functional components in spent grains, (2) applications of spent grains in functional materials and energy supply, and (3) extraction and utilization methods of high value-added functional components in spent grains. Further, the latest progress in the industrial-scale resource utilization of spent grains implemented by Chinese Baijiu enterprises was reviewed. Finally, the challenges hindering the scaled-up production of spent grains resource utilization technologies were discussed, along with proposed future research directions. Only by integrating methods from diverse studies, optimizing high-value component extraction processes, and establishing multi-level cascading resource utilization systems-while minimizing waste emissions and resource loss during processing-can the full value of spent grains be realized. Coupled with policy incentives and market-driven promotion, such an integrated framework can drive the green and sustainable development of Chinese Baijiu industry and serve as a replicable model for global distilled spirits sectors.

酒糟作为白酒酿造的副产品，随着白酒工业的发展而不断增加。废粮资源化利用是我国白酒企业可持续发展和实现双碳目标的关键。本文首先介绍了固态发酵白酒的酿造工艺，以及酒糟的来源和成分。在此基础上，对近年来主要的20种不同的废粮资源化利用方法的研究进展进行了综合总结和评价，并将其分为3个方面：(1)废粮营养物质和功能成分的直接利用方法；(2)废粮在功能材料和能量供应中的应用；(3)废粮中高附加值功能成分的提取与利用方法。综述了我国白酒企业在酒糟产业化资源化利用方面的最新进展。最后，讨论了阻碍废粮资源化技术规模化生产的挑战，并提出了未来的研究方向。只有整合多种研究方法，优化高价值成分提取工艺，建立多层次级联的资源利用体系，同时最大限度地减少加工过程中的废物排放和资源损失，才能实现废粮的全部价值。结合政策激励和市场推动，这样的整体框架可以推动中国白酒产业的绿色可持续发展，并为全球蒸馏酒行业提供可复制的模式。

Global food production drives planetary-boundary transgressions, including nitrogen and phosphorus cycle disruption, land use change, and climate change. Increasing nutrient circularity can improve sustainability. This study explores an integrated approach that combines a recirculating aquaculture system (RAS) with biochar from forestry-residue pyrolysis to improve process-level nutrient retention while producing carbon-rich biochar with potential for soil-carbon storage upon land application. In RAS, biochar acts as a filter, capturing nutrients and transforming waste into nutrient-enriched biochar for agriculture. Substance Flow Analysis shows that integration increases nitrogen retention from 30.6 % to 44.6 % and phosphorus retention from 25.5 % to 99.6 % versus separate RAS and pyrolysis. This demonstrates the potential of linking aquaculture, forestry, and agriculture with biochar to support more circular and sustainable food production. This early-stage study examines how and to what extent the approach influences nutrient flows under different assumptions and evaluates a simple recovery-efficiency indicator for assessing circularity in integrated systems.

全球粮食生产推动了地球边界越界，包括氮和磷循环中断、土地利用变化和气候变化。增加养分循环可以提高可持续性。本研究探索了一种综合方法，将循环水产养殖系统（RAS）与林业残渣热解产生的生物炭相结合，以提高工艺水平的养分保留，同时生产富含碳的生物炭，并在土地应用时具有土壤碳储存的潜力。在RAS中，生物炭充当过滤器，捕获营养物质并将废物转化为农业所需的营养丰富的生物炭。物质流分析表明，与单独的RAS和热解相比，整合使氮保留率从30.6%提高到44.6%，磷保留率从25.5%提高到99.6%。这表明了将水产养殖、林业和农业与生物炭联系起来，以支持更加循环和可持续的粮食生产的潜力。这项早期研究考察了在不同假设下该方法如何以及在多大程度上影响养分流动，并评估了用于评估综合系统循环的简单回收率效率指标。

Synergistic advantages between organic solid wastes may facilitate a strategy shift from mono-management to co-management, while the implementation of these transformations should be considered in terms of its environmental and economic performance. This study utilized life cycle assessment and life cycle cost analysis to quantitatively assess the co-management and mono-management strategies for the incineration of sewage sludge (SS) and municipal solid waste, composting of SS and pig manure, and anaerobic digestion (AD) of SS and food waste. The results showed that co-incineration resulted in a 7.67% decrease in feasibility, whereas co-composting and co-AD demonstrated increases of 76.50% and 21.36%, respectively. Sensitivity analysis indicated that global warming potential was positively correlated with SS addition in co-incineration and co-AD, but negatively in co-composting. This study recommends adopting co-management methods tailored to local conditions and optimizing waste composition to guide future policy towards more sustainable and safer waste management.

有机固体废物之间的协同优势可能促进从单一管理到共同管理的战略转变，而这些转变的执行应根据其环境和经济绩效加以考虑。本研究利用生命周期评估和生命周期成本分析，定量评估了污泥焚烧与城市生活垃圾、污泥与猪粪堆肥、污泥与食物垃圾厌氧消化的协同管理和单一管理策略。结果表明，共焚烧的可行性降低了7.67%，而共堆肥和共ad的可行性分别提高了76.50%和21.36%。敏感性分析表明，全球变暖潜势与共焚烧和共ad中SS添加量呈正相关，而与共堆肥中SS添加量呈负相关。本研究建议采用因地制宜的共同管理方法，优化废物组成，以指导未来的政策，实现更可持续和更安全的废物管理。

As the rollout of 5G accelerates, its soaring energy demand poses a growing climate challenge. According to a World Bank Group report, the Information and Communication Technology (ICT) sector is responsible at least 1.7 % of global greenhouse gas (GHG) emissions. This study examines an intelligent suite of energy-saving methods—particularly deep reinforcement learning sleep modes, adaptive RIS, and cluster-zooming cell-free MIMO at the network edge, alongside dynamic power adjustments on user devices—and quantifies their environmental impact using an ICT-focused environmentally extended input-output (EEIO) model. Anchored in the UK’s 2019 economic and emissions data, the model captures both production and consumption effects across 33 sectors. Results spotlight two standout strategies—AI-powered base station sleep control and refined user device signaling—as catalysts for deep, economy-wide CO₂ reductions. Notably, the financial, IT services, and programming sectors benefit most from these ripple effects. Our findings outline practical paths towards greener 5G deployments and underscore policy opportunities to amplify their socioeconomic value.
