Green methanol serves as a vital bridge between the chemical and energy sectors in achieving carbon neutrality. This review critically summarizes recent progress in biomass gasification, CO₂ hydrogenation, and hybrid configurations, integrating catalytic, techno-economic, and policy perspectives. Biomass gasification shows high technological readiness but faces feedstock and cost limitations, while CO₂ hydrogenation (e-methanol) offers long-term scalability constrained by hydrogen and electrolyzer costs. Integrating biomass-derived syngas with green hydrogen provides a synergistic pathway to enhance carbon efficiency. Catalyst development has shifted from conventional Cu-ZnO-Al₂O₃ to advanced noble-metal, bimetallic, and oxide-hybrid systems, emphasizing activity, stability, and sustainability. Economically, bio-methanol and e-methanol currently cost about 250–1000 USD t⁻¹ and 2000–2400 USD t⁻¹ in 2025, respectively. With continued technological learning, economies of scale, and carbon pricing incentives, their costs are projected to decline to approximately 300–400 USD t⁻¹ and 700–800 USD t⁻¹ by 2050. This review underscores three priorities for the sustainable scale-up of green methanol: improving catalytic and process efficiency, integrating renewable-based systems, and implementing supportive policy frameworks. Their convergence will enable methanol to become a cornerstone of the future carbon-neutral energy landscape.

绿色甲醇是化工和能源部门之间实现碳中和的重要桥梁。本文综述了生物质气化、CO2加氢和混合配置的最新进展，整合了催化、技术经济和政策观点。生物质气化显示出高度的技术成熟度，但面临原料和成本的限制，而二氧化碳加氢（e-甲醇）提供了长期的可扩展性，但受到氢气和电解槽成本的限制。将生物质衍生合成气与绿色氢相结合，提供了一种提高碳效率的协同途径。催化剂的发展已经从传统的Cu-ZnO-Al2O3转向先进的贵金属、双金属和氧化物混合体系，强调活性、稳定性和可持续性。经济上，目前生物甲醇和电子甲醇的成本在2025年分别为250-1000美元和2000-2400美元。随着不断的技术学习、规模经济和碳定价激励措施，预计到2050年，它们的成本将下降到大约300-400美元和700-800美元。本综述强调了可持续扩大绿色甲醇规模的三个优先事项：提高催化和工艺效率，整合可再生系统，实施支持性政策框架。它们的融合将使甲醇成为未来碳中和能源格局的基石。

Modern power system development drives electrical infrastructure upgrades, creating substantial recyclable waste, notably transformers, demanding enhanced lifecycle management and circular resource strategies. In this study, a computational methodology was developed for evaluating the stock and waste of transformers across China from 1978 to 2050, quantifying the resource recovery potential, evaluating environmental impacts and measuring pollution control and carbon reduction effects of recycling waste transformers. The annual waste generation of ≥35 kV transformers is projected to demonstrate temporal growth patterns. Low-voltage transformers offer substantially greater potential for resource recovery than high-voltage systems. Among them, 110 kV units contribute most significantly to carbon reduction, conserving energy, and enhancing environmental outcomes. In contrast, transformers rated at 750 kV and above exhibit relatively modest gains in environmental performance. This study lays a scientific groundwork for managing waste from power equipment and provides vital strategic guidance for fostering circular economy initiatives in the energy industry.

现代电力系统的发展推动了电力基础设施的升级，产生了大量可回收的废物，特别是变压器，要求加强生命周期管理和循环资源战略。本文建立了1978 - 2050年中国变压器存量和废弃物的计算方法，量化了资源回收潜力，评估了废旧变压器的环境影响，并测量了废旧变压器的污染控制和碳减排效果。预计≥35kv变压器的年废物产生量将呈现时间增长模式。与高压系统相比，低压变压器提供了更大的资源回收潜力。其中，110千伏机组对减少碳排放、节约能源和提高环境效益的贡献最大。相比之下，额定电压为750千伏及以上的变压器在环境性能方面表现出相对适度的改善。本研究为管理电力设备废弃物奠定了科学基础，并为促进能源行业的循环经济举措提供了重要的战略指导。

In Germany hundreds of thousands of kilometers of wastewater pipes will need to be modernized in the near future. Two upkeeping approaches are compared by using a cradle-to-grave life cycle assessment: trenchless rehabilitation with cured-in-place glass fiber liners versus open-trench replacement with concrete or reinforced concrete pipes. Due to the very long service life of over 50 years, estimates are made for end-of-life treatment. Thermal recycling in a cement plant is assumed optimal for the disposal of glass-fiber liners. However, the end-of-life treatment of the liners is of minor environmental importance compared to the installation efforts of concrete pipes. The analysis shows some environmental advantages for glass liners in the production stage but major advantages in the installation stage, depending on the actual installation conditions. Overall, the rehabilitation by liners shows obvious environmental advantages over the replacement of wastewater pipes.

在德国，数十万公里的污水管道需要在不久的将来进行现代化改造。通过使用从摇篮到坟墓的生命周期评估，对两种维护方法进行了比较：使用固化玻璃纤维衬垫的非开挖修复与使用混凝土或钢筋混凝土管道的开沟替代。由于使用寿命很长，超过50年，因此对报废处理进行了估计。假设水泥厂热回收是玻璃纤维衬垫处理的最佳选择。然而，与混凝土管道的安装工作相比，衬垫的报废处理对环境的重要性较小。分析表明，玻璃衬垫在生产阶段具有一定的环境优势，但主要优势在安装阶段，具体取决于实际安装条件。总体而言，班轮修复比更换污水管道具有明显的环境优势。

Land development intensity surrounding protected areas (PAs) is rising, yet its impacts on internal fragmentation remain unclear at the global scale. Using data for 4995 PAs worldwide from 2000 to 2020, we quantified the surrounding land development intensity and two forms of within-PA fragmentation on the global, continental, and biome scales: landscape fragmentation (the breaking up of an entire PA landscape mosaic) and habitat fragmentation (the breaking up of a single habitat type in a PA landscape). Our results revealed that more than half of PAs experienced increasing development pressures from surrounding areas, with the steepest rise within 1 km of PA boundaries. Among PAs with intensifying surrounding land development, habitat fragmentation increased more broadly across PAs than landscape fragmentation. Habitat area density (H_AD) and edge density (ED) were the most responsive metrics to surrounding development. In Asia’s Tropical & Subtropical Moist Broadleaf Forests, 73.7 % of PAs showed declining H_AD under intensifying surrounding development, indicating pronounced habitat fragmentation. In South America, 74.1 % of PAs exhibited increasing ED, reflecting heightened landscape fragmentation. Asian tropical moist forests emerged as a global hotspot with PAs such as Keo Seima, Nam Ha, and Panbari RF showed strong multi-metric responses. External pressures arising from surrounding development—such as pollution, invasive species, fires, and hydrological alterations—may extend into the interiors of PAs and affect their internal habitat structure, representing a persistent challenge for conservation management.

保护区周边土地开发强度呈上升趋势，但其对内部破碎化的影响在全球范围内尚不清楚。利用2000 - 2020年全球4995个保护区的数据，在全球、大陆和生物群系尺度上量化了周边土地开发强度和两种类型的PA内破碎化：景观破碎化（整个PA景观的破碎化）和栖息地破碎化（PA景观中单一栖息地类型的破碎化）。研究结果显示，超过一半的保护区承受着来自周边地区的开发压力，其中在保护区边界1公里内的增长幅度最大。在周边土地开发加剧的保护地中，生境破碎化的增加幅度大于景观破碎化。生境面积密度（H_AD）和边缘密度（ED）是对周边发展最敏感的指标。在亚洲热带和亚热带湿润阔叶林中，73.7%的保护区H_AD随着周边开发的加剧而下降，表明栖息地破碎化程度明显。在南美洲，74.1%的保护区ED增加，反映出景观破碎化加剧。亚洲热带湿润森林成为全球热点，高西马、南下和潘巴里等森林保护区表现出强烈的多尺度响应。来自周围发展的外部压力，如污染、入侵物种、火灾和水文变化，可能会延伸到保护区内部并影响其内部栖息地结构，这对保护管理来说是一个持续的挑战。

Securing critical raw materials for net-zero energy systems and green technologies, has become a global priority. This urgency is fuelled by increasing demand, dwindling natural reserves, and rising geopolitical instabilities. Urban waste streams, often rich in metal concentrations than natural ores, are emerging as viable alternative for metal recovery. Bioleaching, a natural process utilising microorganism to mobilise metals from solid mineral matrices, has become increasingly popular as a sustainable and economically attractive alternative to conventional mining of minerals, particularly for low-grade ores and waste-derived feedstocks. The attractiveness of bioleaching lies in low environmental impact and high efficiency, even at low metal concentrations. This review explores different metal-bearing secondary materials containing critical, precious, and rare earth elements (REEs) as potential feedstocks for bioleaching. It traces the evolution of bioleaching from natural ore processing to its growing utility in urban waste valorisation within a circular economy framework. It compares bioleaching process in natural ores versus urban waste, while showcasing recent advancements toward commercial implementation. The review also identifies existing challenges and proposes strategies for improvement. Finally, it articulates bioleaching's potential for integration into a circular economy model, emphasising its role in enabling sustainable metal recovery and achieving carbon neutrality goals.

确保零净能源系统和绿色技术的关键原材料，已成为全球的优先事项。需求增加、自然储备减少和地缘政治不稳定加剧加剧了这种紧迫性。城市废物流的金属含量往往比天然矿石高，正成为金属回收的可行替代办法。生物浸出是一种利用微生物从固体矿物基质中动员金属的自然过程，作为一种可持续和经济上有吸引力的替代传统矿物开采的方法，特别是对于低品位矿石和废物来源的原料，已经越来越受欢迎。生物浸出的吸引力在于低环境影响和高效率，即使在低金属浓度下也是如此。本文综述了含关键、珍贵和稀土元素的不同含金属二次材料作为生物浸出的潜在原料。它追溯了生物浸出从自然矿石加工到在循环经济框架内城市废物增值中日益增长的效用的演变。它比较了天然矿石和城市废物的生物浸出过程，同时展示了最近在商业实施方面的进展。审查还确定了现有的挑战，并提出了改进战略。最后，它阐明了生物浸出融入循环经济模式的潜力，强调了其在实现可持续金属回收和实现碳中和目标方面的作用。

Hospitals discard 30% of prepared meals, causing financial losses and contributing 5–10% of the facility’s CO₂ emissions. This environmental threat is concerning, given that 20–50% of patients are malnourished upon admission, and inadequate nutrition during hospitalization increases the risk of complications. Despite growing sustainability imperatives, the lack of integrated approaches to reduce hospital food waste that consider patient-specific needs and demand uncertainty remains a challenge.

This study proposes a chance-constrained two-stage stochastic programming model to minimize food waste costs, last-minute purchases, and storage costs, under uncertain demand. Validated through a case study in Florida, the model reduces food storage costs by 60%, decreases annual food waste by 2 tons, and lowers the climate impact by 15% in the most probable scenario. The study also reveals a nonlinear relationship in which costs increase faster than the incremental benefits of meeting nutritional requirements. This work supports hospital sustainability by minimizing waste and improving patient care.

医院丢弃了30%的准备好的饭菜，造成了经济损失，并贡献了5-10%的设施二氧化碳排放量。考虑到20-50%的患者在入院时营养不良，住院期间营养不足会增加并发症的风险，这种环境威胁令人担忧。尽管可持续发展的必要性日益增强，但缺乏考虑到患者特定需求和需求不确定性的减少医院食物浪费的综合方法仍然是一个挑战。

The growing adoption of electric vehicles has significantly increased demand for advanced energy storage solutions. Lithium-ion batteries are at the forefront, primarily used in electric vehicles and increasingly in stationary renewable energy storage systems. However, their reliance on critical resources has spurred research into alternative cathode materials and next-generation battery types. Since it is unclear whether such advances can offset expected material shortages, we assess whether global reserves, production, and recycling capacity can support the projected battery growth. Based on IPCC scenarios up to 2050, our analysis shows that even under optimistic assumptions, the planned battery expansion in the Sustainability and Middle of the Road scenarios cannot be achieved. Excluding recycling would lead to a 33% increase in cumulative primary material demand, exacerbating supply risks and resulting in greater underproduction. These findings underscore the importance of expanding recycling, second-life, and production infrastructure, as well as pursuing a diversified technology strategy.

电动汽车的日益普及大大增加了对先进储能解决方案的需求。锂离子电池处于最前沿，主要用于电动汽车，并越来越多地用于固定式可再生能源存储系统。然而，它们对关键资源的依赖推动了对替代阴极材料和下一代电池类型的研究。由于尚不清楚这些进步是否可以抵消预期的材料短缺，我们评估了全球储备、生产和回收能力是否能够支持预计的电池增长。基于IPCC到2050年的情景，我们的分析表明，即使在乐观的假设下，可持续性和中间道路情景中的计划电池扩张也无法实现。排除回收将导致累计初级材料需求增加33%，加剧供应风险并导致更大的生产不足。这些发现强调了扩大回收、二次使用和生产基础设施以及追求多元化技术战略的重要性。

Urban resource circularity – the symbiotic sharing of material and energy between urban actors - reduces demand for raw resources and waste generation. Researchers currently lack a unified vernacular to study the many forms of circularity in cities. This review examines urban resource circularity strategies from the academic and gray literature to propose a typology of circularity based on the embeddedness of different practices in urban systems. We identify three complementary forms of urban circularity: industrial symbiosis, conventional waste management, and urban symbiosis. Urban symbiosis is distinct in that it leverages the spatial and social concentration unique to cities, creating opportunities for engaged city dwellers to actively shape circularity. Despite being utilized frequently in practice, urban symbiosis is critically undertheorized. By rigorously defining urban symbiosis, we provide a common language to discuss and synthesize disparate strands of literature on citizen-led urban circularity. Urban symbiosis, therefore, provides a potent lens for exploring and ultimately reimagining resource flows in cities. We propose an agenda for future research on urban symbiosis and envision it as a way for citizens to democratically shape more circular and just urban futures by exercising their “right to the sustainable city.”

城市资源循环——城市参与者之间物质和能源的共生共享——减少了对原始资源的需求和废物的产生。研究人员目前缺乏一种统一的方言来研究城市中多种形式的圆形。本文回顾了来自学术文献和灰色文献的城市资源循环策略，提出了一种基于城市系统中不同实践的嵌入性的循环类型。我们确定了三种互补的城市循环形式：工业共生、传统废物管理和城市共生。城市共生的独特之处在于，它利用了城市特有的空间和社会集中度，为城市居民创造了积极塑造圆形的机会。尽管在实践中经常使用，但城市共生理论严重不足。通过严格定义城市共生，我们提供了一种共同的语言来讨论和综合关于公民主导的城市循环的不同文献。因此，城市共生为探索并最终重新构想城市资源流动提供了一个强有力的视角。我们提出了未来城市共生研究的议程，并将其设想为公民通过行使他们的“可持续城市权利”，民主地塑造更循环、更公正的城市未来的一种方式。

Material archetypes are essential to bottom-up building material stock-flow modelling, analogous to the role of energy archetypes in building stock energy modelling, for supporting circular construction. Using a bill-of-quantities dataset of 211 buildings in China, this study evaluates the effect of 13 non-collinear structural, morphological, semantic, socioeconomic, and geographic variables on building material intensity variability to identify key archetyping variables. Results indicate that structural and geographic variables exert the strongest effects on overall material intensity, while material-specific variability is governed by distinct variables. This study further identifies optimal archetyping variable combinations and suboptimal alternatives for accommodating varying data availability. Incorporating more than six variables tends to diminish archetyping due to the accumulation of minor yet inherent information redundancy among variables. These findings provide quantitative criteria for building material archetyping to reduce stock-flow modelling uncertainties, while offering valuable references for material-embodied energy and carbon archetype development.

材料原型对于自下而上的建筑材料库存流建模至关重要，类似于能源原型在建筑库存能源建模中的作用，以支持圆形建筑。利用中国211栋建筑的工程量清单数据，本研究评估了13个非共线结构、形态、语义、社会经济和地理变量对建筑材料强度变异性的影响，以确定关键原型变量。结果表明，结构和地理变量对整体材料强度的影响最大，而材料特异性变异受不同变量的支配。本研究进一步确定了适应不同数据可用性的最佳原型变量组合和次优替代方案。合并六个以上的变量往往会减少原型，因为变量之间积累了少量但固有的信息冗余。这些发现为建筑材料原型提供了定量标准，以减少库存流模型的不确定性，同时为材料蕴含能源和碳原型的开发提供了有价值的参考。

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。
