This study evaluates the economic and environmental feasibility of Municipal Solid Waste (MSW) sorting and decontamination technologies across urban, suburban, and rural areas. Using Techno-Economic Analysis (TEA) and Life Cycle Assessment (LCA), the research assesses cost-effectiveness and environmental impacts, with a focus on cost variability analyzed through Monte Carlo simulations. Findings indicate significant cost differences based on population density: rural areas incur high costs up to $764/ton due to low waste volumes and limited infrastructure, whereas suburban and urban areas have more feasible costs ranging from $36.3 to $142.5/ton. Environmental impacts also vary, with greenhouse gas emissions at 171 kg CO₂ eq/ton for copy paper and 118.6 kg CO₂ eq/ton for plastics. PM2.5 levels are 9.1 g/ton for copy paper and 6.3 g/ton for plastics, with sorting lines being the main contributors. Monte Carlo simulations reveal a 50% probability of costs being below $102.26/ton for copy paper and $115.8/ton for plastics in suburban settings. The study underscores the importance of customized waste management strategies to improve economic viability and sustainability based on local conditions.

本研究评估了城市固体废物 (MSW) 分类和净化技术在城市、郊区和农村地区的经济和环境可行性。研究利用技术经济分析（TEA）和生命周期评估（LCA），评估了成本效益和环境影响，重点是通过蒙特卡洛模拟分析的成本变化。研究结果表明，人口密度不同，成本差异也很大：农村地区由于废物量少，基础设施有限，成本高达 764 美元/吨，而郊区和城市地区的成本更低，从 36.3 美元/吨到 142.5 美元/吨不等。对环境的影响也各不相同，复印纸的温室气体排放量为 171 千克二氧化碳当量/吨，塑料为 118.6 千克二氧化碳当量/吨。复印纸和塑料的 PM2.5 分别为 9.1 克/吨和 6.3 克/吨，分拣线是主要的排放源。蒙特卡罗模拟显示，在郊区环境中，复印纸和塑料的成本分别低于 102.26 美元/吨和 115.8 美元/吨的可能性分别为 50%。这项研究强调了定制化废物管理战略的重要性，以根据当地条件提高经济可行性和可持续性。

To maximize circularity, remaining value in electric vehicle (EV) batteries can be retained through deploying different strategies such as reusing and repurposing to enable second life applications before they are recycled. Since EV battery ecosystems for the so-called battery second life are at early, emergence stages, they are characterized by uncertainties and high complexity. Despite previous analyses on the topic, collaboration in terms of roles, hierarchies, as well as the circular ecosystem dynamics remain unclear. We thus conduct a systematic literature review, applying a complex adaptive systems lens to map the literature concerning the three core dimensions of ecosystems: conceptual, structural, and temporal. Results point to the need to collaborate to enable circular ecosystems for EV battery second life, but also hint to high diversity of actors- over 40 types of actors potentially relevant for EV battery second life ecosystems – and various challenges for collaboration in such ecosystems.

为了最大限度地实现循环利用，可以通过部署不同的策略（如重复使用和重新利用）来保留电动汽车（EV）电池的剩余价值，以便在电池被回收之前实现第二次生命应用。由于所谓的电池第二生命的电动汽车电池生态系统正处于早期新兴阶段，因此具有不确定性和高度复杂性的特点。尽管以前对这一主题进行过分析，但在角色、等级以及循环生态系统动态方面的合作仍不明确。因此，我们进行了一次系统的文献综述，从复杂适应系统的视角出发，对有关生态系统三个核心维度（概念、结构和时间）的文献进行了梳理。研究结果表明，有必要通过合作实现电动汽车电池二次生命的循环生态系统，但同时也提示了参与者的高度多样性--超过 40 种可能与电动汽车电池二次生命生态系统相关的参与者--以及在此类生态系统中开展合作所面临的各种挑战。

In pursuit of greenhouse gas emissions reductions, the environmental systems community has developed material flow analyses to describe the transformation of resources into goods, while the manufacturing technology community has developed innovations that can affect the production of individual components. However, these two communities have remained disconnected, because neither is able to relate their insights to their point of common interest: the global production of components. For the first time, this paper connects global analyses of the use of steel and aluminium to the production of components, classified by the metal forming processes which shape them. The results demonstrate the proportions of steel and aluminium used in ten distinct component groups, at global level, and for the major product groups which drive demand for these two metals. This helps both to prioritise requirements for innovation in design and manufacturing and to evaluate of the emissions potential of such innovations.

为了减少温室气体排放，环境系统界开发了物质流分析来描述资源向产品的转化，而制造技术界则开发了能够影响单个组件生产的创新技术。然而，这两个群体一直处于脱节状态，因为他们都无法将自己的见解与共同关心的问题联系起来：零部件的全球生产。本文首次将钢和铝的全球使用分析与按金属成型工艺分类的零部件生产联系起来。分析结果表明，在全球范围内，钢和铝在十个不同的部件组中的使用比例，以及推动这两种金属需求的主要产品组的使用比例。这既有助于确定设计和制造创新要求的优先次序，也有助于评估此类创新的排放潜力。

Providing effective solid waste and resources management (SWM) is essential to tackle plastics pollution, reduce carbon emissions and local air pollution from open burning, avoid disease spreading and enable circularity. Official development finance (ODF) is vital in providing relevant infrastructure and capacity development. We developed a novel standardised methodology to analyse OECD ODF data and applied it to 2003–2021, offering insights on the scale, flows and changes in SWM ODF. Despite an 8-fold increase, SWM-focused ODF is still very low, representing just 0.41 % of all ODF; and an order of magnitude less than water and sanitation ODF. Low-income countries received only 8 % of SWM ODF. Total commitments in 2021 were ca. 1.8 Billion USD - significantly short of the >30 Billion USD investment estimated as necessary for substantially reducing plastics pollution. The multi-lateral environmental agreement under negotiation (‘Plastics Treaty) needs to set ambitious targets for ODF and wider international co-operation.

提供有效的固体废物和资源管理（SWM）对于解决塑料污染、减少露天焚烧造成的碳排放和当地空气污染、避免疾病传播和实现循环至关重要。官方发展融资（ODF）在提供相关基础设施和能力发展方面至关重要。我们开发了一种新颖的标准化方法来分析经合组织的官方发展资金数据，并将其应用于 2003-2021 年，从而为我们提供了有关 SWM 官方发展资金的规模、流量和变化的见解。尽管增长了 8 倍，但以 SWM 为重点的 ODF 仍然很低，仅占所有 ODF 的 0.41%；比供水和卫生 ODF 低一个数量级。低收入国家仅获得了 8%的全部门办法下可持续发展目标。2021 年的承诺总额约为 18 亿美元。18 亿美元，远远低于大幅减少塑料污染所需的 300 亿美元投资。正在谈判的多边环境协定（《塑料条约》）需要为全境自净和更广泛的国际合作设定雄心勃勃的目标。

The conventional wet process for P recovery from sewage sludge incineration ash (SSIA) demands substantial chemicals (e.g., acids and alkalis for subsequent P extraction and precipitation) and water, causing economic and environmental drawbacks. We minimized them by employing concrete slurry wastewater (CSWW) as alkali and water sources, achieving over 90 % P recovery at pH 7. The P product contained ∼ 12 % P and low metal contaminants, meeting the regulations for inorganic fertilizer. Powder X-ray diffraction and chemical equilibrium simulations revealed that the product comprised hydroxyapatite crystal (HAp) and amorphous CaHPO₄, forming at pH ∼ 4 and partially converting to HAp at higher pH. The supernatant was utilized in subsequent P extraction cycles to conserve water. By-products were assessed for hazard and recycled into cementitious materials, adhering to the zero waste principle. This study exemplifies the synergy between P recovery from SSIA and cementitious material production, transforming wastes into valuable resources.

从污水污泥焚烧灰（SSIA）中回收 P 的传统湿法工艺需要大量的化学品（如用于后续 P 提取和沉淀的酸和碱）和水，造成了经济和环境方面的弊端。我们采用混凝土泥浆废水（CSWW）作为碱源和水源，最大限度地减少了这些问题，在 pH 值为 7 的条件下，实现了超过 90% 的 P 回收率。粉末 X 射线衍射和化学平衡模拟显示，产品由羟基磷灰石晶体（HAp）和无定形 CaHPO4 组成，在 pH 值为 4 时形成，pH 值较高时部分转化为 HAp。上清液用于后续的磷萃取循环，以节约用水。对副产品进行了危险性评估，并将其回收利用到水泥基材料中，以实现零废物原则。这项研究体现了从 SSIA 中回收 P 与生产水泥基材料之间的协同作用，将废物转化为有价值的资源。

The current recycling methods to recover metal contents from electronic wastes (e-wastes) are primarily chemical based, such as hydrometallurgy, pyrometallurgy. These methods typically do not involve pre-treatments to remove non-metallic components, which causes increasing reagent and energy consumption, and greenhouse gas emission during recycling. Mechanical methods exploiting differences in material properties, such as gravity, magnetic, electrostatic, can achieve pre-treatment which receive increasing attention. Amongst different mechanical methods, froth flotation utilizing surface hydrophobicity to achieve the desired separation appears to receive less attention but can be very promising to recycle a variety of e-wastes. In this work, the challenges and advances in the recovery of metals from three main e-wastes, including spent lithium-ion batteries (S-LIBs), waste printed circuit boards (WPCBs), and spent photovoltaic solar panels (S-PVs), using flotation were reviewed. The work also conducted a life cycle analysis to assess the environmental impact of flotation in recycling these e-wastes. According to TRACI standards, flotation reagents have the highest environmental impact compared to electricity and water consumption. The study suggests that flotation can serve as an effective pre-treatment operation prior to the chemical treatment to improve the overall the e-waste recycling but future research is still needed.

目前从电子废物（e-wastes）中回收金属成分的回收方法主要以化学方法为主，如湿法冶金和火法冶金。这些方法通常不涉及去除非金属成分的预处理，导致试剂和能源消耗不断增加，并在回收过程中排放温室气体。利用材料特性差异（如重力、磁力、静电）的机械方法可以实现预处理，受到越来越多的关注。在各种机械方法中，利用表面疏水性实现理想分离的泡沫浮选法似乎较少受到关注，但在回收各种电子废物方面却大有可为。本研究综述了利用浮选法从三种主要电子废物（包括废锂离子电池（S-LIB）、废印刷电路板（WPCB）和废光伏太阳能电池板（S-PV））中回收金属所面临的挑战和取得的进展。这项工作还进行了生命周期分析，以评估浮选在回收这些电子废物时对环境的影响。根据 TRACI 标准，与耗电量和耗水量相比，浮选试剂对环境的影响最大。研究表明，浮选可作为化学处理前的有效预处理操作，以改善电子废物回收利用的整体效果，但仍需进行进一步研究。

This study presents a two-stage process to recover phosphorus (P) from sewage sludge (SS) hydrochar, aimed at reducing trace element (TE) contamination. SS, mixed with Al-rich alum sludge (AS), underwent acidic HTC to convert Ca-P to Al-P. Alkaline extraction of hydrochar produced a P-rich, TE-deficient extract, as Al-P dissolves at high pH (> 12), leaving TEs insoluble. Optimal conditions for maximum P recovery were high temperature (∼240 °C), Al/P molar ratio (APMR) of ∼4, and feedstock pH of ∼3 – 4. This design process achieved 82 % alkaline P recovery, 34 % higher than the reference process. Overall P recovery ranged from 59 – 75 % in the design process, compared to 30 – 37 % in the reference process. Solid-state NMR revealed the Al-P association in hydrochar through surface complexation. TEs were mainly concentrated in the hydrochar. Thus, this method offers co-treatment of two waste streams with simultaneous resource recovery.

本研究介绍了一种从污水污泥（SS）水炭中回收磷（P）的两阶段工艺，旨在减少微量元素（TE）污染。污水污泥与富含铝的明矾污泥（AS）混合，经过酸性 HTC 将 Ca-P 转化为 Al-P。由于 Al-P 在高 pH 值（> 12）下溶解，导致 TE 无法溶解，因此碱性萃取水碳会产生富含 P 但缺乏 TE 的萃取物。实现最高钾回收率的最佳条件是高温（∼240 °C）、铝/钾摩尔比（APMR）∼4、原料 pH 值∼3 - 4。该设计工艺的碱性磷回收率达到 82%，比参考工艺高 34%。设计工艺的总磷回收率为 59 - 75%，而参考工艺为 30 - 37%。固态核磁共振显示，铝-磷通过表面络合作用在水碳中结合。TE 主要集中在水碳中。因此，该方法可对两种废物流进行协同处理，同时实现资源回收。

Recycling initiatives target increased recycling rates and closing packaging loops, yet practical, political, and industrial challenges may remain unnoticed. This study delves into the mechanical, processing, and morphological disparities within a polypropylene (PP) polymer stream, especially for yogurt cups. The waste source (mixed MSW or plastic collection) does not considerably impact mechanical properties. However, analyzing PP packaging diversity raises doubts about achieving high-quality recyclate. Categorization attempts include thermoforming, injection molding, and copolymers. An idealized stream of yogurt cups reveals complexities due to various decoration technologies and processing methods. Within a closed-loop system for yogurt cups, thermoforming and injection molding are crucial, prompting the imitation of virgin and post-consumer cup materials. A threshold value of 70 wt.% and deterioration effects are identified alongside common fillers and polymers. As high-quality regranulate becomes increasingly essential, we must also consider the effects of processing methods and aim for a clean, homogeneous stream.

回收利用倡议的目标是提高回收利用率和闭合包装循环，但实际、政治和工业方面的挑战可能仍未引起人们的注意。本研究深入探讨了聚丙烯（PP）聚合物流，尤其是酸奶杯的机械、加工和形态差异。废物来源（混合城市生活垃圾或塑料收集）对机械性能的影响不大。然而，对聚丙烯包装多样性的分析却让人怀疑能否获得高质量的回收物。分类尝试包括热成型、注塑成型和共聚物。理想化的酸奶杯流显示了各种装饰技术和加工方法的复杂性。在酸奶杯的闭环系统中，热成型和注塑成型至关重要，这促使人们模仿原生和消费后的杯子材料。70 wt.%的临界值和劣化效应与常见的填料和聚合物一起被确定下来。随着高质量再造粒变得越来越重要，我们还必须考虑加工方法的影响，并以获得清洁、均匀的原料流为目标。

A threshold value of 70 wt.% and deterioration effects are identified alongside common fillers and polymers. As high-quality regranulate becomes increasingly essential, we must also consider the effects of processing methods and aim for a clean, homogeneous stream.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"212 ","pages":"Article 107944"},"PeriodicalIF":11.2,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142420130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Climate change has seriously affected the resource utilization of the energy-water-carbon system, while the system carbon emissions continuously act on climate change. Given the interaction between the two, there is an urgent need to facilitate the rational allocation of system resources to realize the positive feedback between climate change and energy-water-carbon system development. In this study, an interval stochastic fuzzy integer programming (ISFIP) model is developed to support resource planning and management of the energy-water-carbon system in response to climate change in China. The developed model has advantages in characterizing the complexity and uncertainty of the energy-water-carbon system and providing optimal system decision-making options under multiple climate change scenarios. The results show that the SSP126-NZE scenario power system would reduce carbon emissions by 16.23 %, air pollutant emissions by 19.31 %, water consumption by 30.96 %, and increase economic benefits by 10.97 %, respectively, compared to the SSP585-STEPS baseline scenario.

气候变化严重影响着能源-水-碳系统的资源利用，而系统的碳排放又不断作用于气候变化。鉴于二者之间的相互作用，迫切需要促进系统资源的合理配置，以实现气候变化与能源-水-碳系统发展之间的正反馈。本研究建立了区间随机模糊整数程序设计（ISFIP）模型，以支持中国应对气候变化的能源-水-碳系统资源规划和管理。所开发的模型在描述能源-水-碳系统的复杂性和不确定性以及提供多种气候变化情景下的最优系统决策方案方面具有优势。结果表明，与 SSP585-STEPS 基线情景相比，SSP126-NZE 情景电力系统将分别减少碳排放 16.23%、大气污染物排放 19.31%、水消耗 30.96%、经济效益增加 10.97%。
