Textile consumption has been continuously increasing, posing significant challenges for waste management and disposal. Pyrolysis offers significant potential for recovering resources from non-degradable textiles (e.g., polyester). However, comprehensive studies on product distribution and the release of hazardous components across diverse textile types remain limited, which restricts the development of high-value resource recovery strategies and leads to potential environmental and health risks. This study systematically investigated the fast pyrolysis (550 °C) characteristics of five pure textiles—cotton (C), wool (W), nylon (N), polyester (T), rayon (R)—and one mixed textile (MT). The results revealed distinct product profiles for different textile types. Cotton-derived bio-oil exhibited high content (83.61 %) of light hydrocarbons (<C10), making it suitable for use as liquid fuel after simple acid removal. Wool pyrolysis generated complex bio-oil requiring secondary cracking. Synthetic fabrics (N, T, R) produced bio-oils with substantial corrosive carboxylic acids (e.g., benzoic acid), necessitating esterification pretreatment for fuel use. MT pyrolysis yielded nitrogen-rich bio-oil (74.77 % N-compounds) containing 37.35 % caprolactam, highlighting its value as a chemical feedstock but requiring carbon black separation from the particulate matter (PM). PM analysis identified viscosity-driven formation in cotton and tar/soot dominance in synthetics. This study provides critical insights into tailoring pyrolysis protocols to specific textile wastes, thereby advancing sustainable resource recovery while mitigating corrosion and pollution risks associated with hazardous by-products.

纺织品消费量持续增长，对废物管理和处置提出了重大挑战。热解为从不可降解的纺织品（如聚酯）中回收资源提供了巨大的潜力。然而，对不同类型纺织品的产品分布和有害成分释放的综合研究仍然有限，这限制了高价值资源回收战略的发展，并导致潜在的环境和健康风险。本研究系统地研究了棉(C)、羊毛(W)、尼龙(N)、涤纶(T)、人造丝(R)五种纯纺织品和一种混纺纺织品（MT）的快速热解（550℃）特性。结果表明，不同类型的纺织品具有不同的产品特征。棉源生物油轻烃（<C10）含量高（83.61%），经简单酸脱后可作为液体燃料使用。羊毛热解产生复杂的生物油，需要二次裂解。合成织物（N， T， R）生产的生物油含有大量腐蚀性羧酸（如苯甲酸），需要酯化预处理用于燃料使用。MT热解产生的富氮生物油（74.77%的n化合物）含有37.35%的己内酰胺，突出了其作为化学原料的价值，但需要从颗粒物（PM）中分离炭黑。PM分析确定了棉花中的粘度驱动地层和合成纤维中的焦油/煤烟主导地层。该研究为针对特定纺织废物定制热解方案提供了重要见解，从而促进可持续资源回收，同时减轻与有害副产品相关的腐蚀和污染风险。

Landfill stability and environmental protection are critical issues in municipal solid waste (MSW) management, especially in tropical countries, where warm and humid conditions can accelerate leachate and gas production. This paper investigated a landfill in Brazil that operated for 24 years (1993–2016), with over 30 % of the MSW consisting of organic matter. Electrical resistivity tomography (ERT) and time-domain induced polarization (IP) surveys were performed along two survey lines for mapping leachate distribution. The results were analyzed using unsupervised machine learning, visualization tools, and descriptive statistics in the R programming language. Standard penetration tests (SPT) were conducted to validate cluster analysis. A comparison of ERT and IP profiles obtained 20 years apart suggested significant leachate presence and varying degradation rates within the waste body, even years after waste disposal activities had ceased. Geoelectrical data were grouped into seven clusters, which were interpreted based on material type (soil and MSW), degree of saturation (partially and fully saturated waste), and organic matter content (from dry to biogeochemically active zones). The SPT tests confirmed complex fluid distribution by revealing leachate ejection and gas emissions at specific regions of the landfill showing low resistivity (below 10 Ωm) and moderate to high chargeability (from 5 to 60 mV/V) and normalized chargeability (from 1 to 7 mS/m). The findings demonstrated the effectiveness of geophysical imaging techniques for site monitoring and highlighted the potential for energy recovery from old MSW.

垃圾填埋场的稳定性和环境保护是城市固体废物管理的关键问题，特别是在热带国家，温暖潮湿的环境会加速渗滤液和气体的产生。本文调查了巴西一个运行了24年（1993-2016）的垃圾填埋场，其中超过30%的生活垃圾由有机物组成。采用电阻率层析成像（ERT）和时域诱导极化（IP）两种测量方法绘制渗滤液分布。使用无监督机器学习、可视化工具和R编程语言中的描述性统计分析结果。进行标准渗透测试（SPT）来验证聚类分析。对相隔20年的ERT和IP资料进行的比较表明，即使在废物处理活动停止数年后，废物体内仍存在大量渗滤液和不同的降解率。地电数据被分成7个簇，根据物质类型（土壤和城市生活垃圾）、饱和度（部分和完全饱和的废物）和有机质含量（从干燥到生物地球化学活跃带）进行解释。SPT测试通过揭示垃圾填埋场特定区域的渗滤液喷射和气体排放，证实了复杂的流体分布，显示出低电阻率（低于10 Ωm）、中高电荷率（从5到60 mV/V）和标准化电荷率（从1到7 mS/m）。研究结果显示地球物理成像技术在监测场地方面的有效性，并突出了从旧都市固体废物中回收能量的潜力。

The accurate estimation of municipal solid waste composition is crucial for effective waste management and resource recovery. Conventional approaches rely on direct sampling, which is both time-consuming and costly. This study presents an accurate and stable Genetic algorithm-based inverse method for estimating municipal solid waste composition without sampling. The method estimates municipal solid waste composition from measurable parameters, including flue gas, working fluid, ash, and leachate, using a genetic algorithm for accurate and stable estimation without physical sampling. The method’s accuracy and stability are validated through numerical simulation experiments involving five distinct municipal solid waste compositions. Data from direct problem simulations, perturbed by random errors, serve as inputs for the genetic algorithm-based inverse solution. Results indicate that the inverse solution is stable. Results indicate that the inverse solution is stable and accurately reproduces the average composition of the five municipal solid waste samples used in the direct method. The results reveal that the estimated composition of municipal solid waste closely matches actual values, demonstrating the feasibility of this genetic algorithm-based approach. The modified methodology is employed at the Aradkooh waste-to-energy power plant in Tehran, Iran. The findings from the Aradkooh power station indicate that the carbon, oxygen, hydrogen, sulfur, moisture, and ash content of municipal solid waste are 27.14, 33.29, 3.16, 0.3, 15.41, and 20.21 percent, respectively. The novelty of this study lies in stabilizing the inverse problem by increasing the number of equations. As a result, the solution achieves higher accuracy and lower estimation errors compared to previous studies.

准确估算城市生活垃圾组成对有效管理和资源回收至关重要。传统的方法依赖于直接抽样，这既耗时又昂贵。提出了一种基于遗传算法的不采样、准确稳定的城市生活垃圾成分反演方法。该方法根据可测量的参数（包括烟气、工作液、灰分和渗滤液）估计城市固体废物的组成，使用遗传算法进行准确和稳定的估计，而无需物理采样。通过五种不同城市生活垃圾组成的数值模拟实验，验证了该方法的准确性和稳定性。来自直接问题模拟的数据，受到随机误差的干扰，作为基于遗传算法的反解的输入。结果表明，反解是稳定的。结果表明，反解稳定，能准确再现直接法中5种城市生活垃圾样品的平均成分。结果表明，估算的城市生活垃圾成分与实际值接近，证明了基于遗传算法的方法的可行性。伊朗德黑兰的Aradkooh废物转化能源发电厂采用了这种改进的方法。Aradkooh电厂的研究结果表明，城市生活垃圾的碳、氧、氢、硫、水分和灰分含量分别为27.14%、33.29%、3.16%、0.3%、15.41%和20.21%。本研究的新颖之处在于通过增加方程数来稳定逆问题。结果表明，与以往的研究相比，该方法具有更高的精度和更小的估计误差。

Increasing global demand for food is driving the need to reduce wastes produced by agriculture to minimise environmental impacts. Black Soldier Fly, Hermetia illucens, can reduce livestock wastes, but research into the safety and scalability of the system is required. Insect bioconversion concerns include potential bioaccumulation of pathogens, antimicrobial resistance genes and heavy metals in larvae and substrates. Here, a semi-commercial-sized insect rearing facility was used to rear larvae on pig slurry, alongside a lab-based experiment using chicken manure. Larval microbiome composition was impacted by substrate, with increased Clostridia in larvae reared on slurry and manure. Pathogens largely decreased in the larvae from starting levels. Both slurry and manure substrates showed time-related changes regardless of insect presence or absence except for E. coli in chicken manure which was reduced in substrates with larvae added (−2.840 LFC vs −1.168 LFC; p<0.05), suggesting that time-associated alterations in the substrate could be more significant than larval presence. Antimicrobial resistance gene changes were dependent on the substrate and gene, with increases found for tetM in chicken manure after larval bioconversion (9.000 vs 10.370 LFC; p<0.001), and for sul2 in larvae reared on chicken manure (3.509 vs −0.985 LFC; p=0.001). In pig slurry-reared larvae, tetM decreased (−1.578 LFC; p<0.001) but there was no difference in sul2. Heavy metal contents generally met permissible standards for animal feed and organic fertilizers. However, there was some non-significant evidence for bioaccumulation of cadmium in slurry-reared larvae 0.18 to 0.70 mg/kg) compared to starter larvae (0.25mg/kg) requiring further study.

全球对粮食的需求不断增加，因此需要减少农业产生的废物，以尽量减少对环境的影响。Hermetia表示，Black Soldier Fly可以减少牲畜浪费，但需要对该系统的安全性和可扩展性进行研究。昆虫的生物转化问题包括病原体、抗菌素抗性基因和重金属在幼虫和底物中的潜在生物积累。在这里，一个半商业化规模的昆虫饲养设施被用来饲养猪浆幼虫，同时使用鸡粪进行实验室实验。基质对幼虫菌群组成有影响，浆液和粪肥饲养的幼虫梭状芽孢杆菌增多。幼虫体内的病原体从开始的水平大大减少。除了鸡粪中的大肠杆菌在添加了幼虫的基质中有所减少（-2.840 LFC vs -1.168 LFC）外，无论昆虫是否存在，浆液和粪肥基质都表现出与时间相关的变化

The improper disposal of pesticide packaging wastes (PPWs) poses serious ecological risks. As one of the world’s largest pesticide users, China established its first national regulatory framework for PPWs management with the promulgation in 2020. Against this background, this study utilized large-scale data from pesticide registration, packaging production, and field collection to systematically evaluate the generation, recycling, and disposal of PPWs across China. Experimental analysis verified that triple rinsing effectively removes residues from typical pesticide formulations, allowing properly cleaned containers to be exempted from hazardous waste control. Building on these results, the study proposes policy pathways to improve PPWs management, including standardized rinsing protocols, extended producer responsibility-based collection incentives, and the integration of QR code traceability to guide and monitor container returns. The findings provide quantitative evidence and actionable recommendations to strengthen national recycling systems and offer a reference for developing countries facing similar challenges.

农药包装废弃物处置不当造成了严重的生态风险。作为世界上最大的农药使用国之一，中国建立了首个ppw管理国家监管框架，并于2020年颁布。在此背景下，本研究利用农药登记、包装生产和田间收集的大量数据，对中国ppw的产生、回收和处置进行了系统评估。实验分析证实，三次冲洗有效地去除典型农药配方中的残留物，使适当清洗的容器免于危险废物控制。在这些结果的基础上，该研究提出了改善ppw管理的政策途径，包括标准化冲洗协议、基于生产者责任的扩展收集激励措施，以及整合二维码可追溯性以指导和监控集装箱退货。研究结果为加强国家回收系统提供了定量证据和可行的建议，并为面临类似挑战的发展中国家提供了参考。

Effective valorization of construction and demolition waste (CDW) is vital for sustainable development, yet current sorting methods remain labour-intensive and inefficient. Despite progress in computer vision, large vision foundation models (LVFMs) exhibit limitations in class-specific segmentation for dynamic waste streams, while their fine-tuning demands significant computational resources. Moreover, efficient annotation of diverse waste classes remains underdeveloped, necessitating a heavy reliance on resource-intensive manual annotation for all model development. To tackle this problem, this study proposes an innovative solution by enhancing LVFMs with spatially aware adapter architectures to enable precise class-specific segmentation and introducing a semi-automated annotation pipeline leveraging few-shot learning. Experiments on an extended dataset, including underrepresented classes like rubber and lights, reveal that our approach achieves an average Intersection over Union (IoU) of 0.744 in fully supervised settings, surpassing baseline adapters by 4.5%. In few-shot scenarios, it attains an IoU of 0.770 for the unseen ‘lights’ class using only 20 training images. The annotation pipeline produces high-quality masks with an average IoU of 0.883, which is comparable to manual annotation performance but substantially less time-consuming. This study contributes to sustainable CDW valorization by introducing a scalable, resource-efficient framework that enhances class-specific segmentation and streamlines annotation, achieving high accuracy in both supervised and few-shot settings.

建筑和拆迁垃圾的有效分类对可持续发展至关重要，但目前的分类方法仍然是劳动密集型和低效的。尽管在计算机视觉方面取得了进步，但大型视觉基础模型（LVFMs）在针对动态废物流的特定类别分割方面存在局限性，而它们的微调需要大量的计算资源。此外，各种废物类别的有效注释仍然不发达，需要对所有模型开发严重依赖资源密集型的手动注释。为了解决这个问题，本研究提出了一种创新的解决方案，通过空间感知适配器架构增强LVFMs，以实现精确的特定类别分割，并引入利用少量学习的半自动注释管道。在扩展数据集（包括橡胶和灯等代表性不足的类）上的实验表明，我们的方法在完全监督设置下实现了0.744的平均交汇（IoU），比基线适配器高出4.5%。在少量拍摄场景中，仅使用20张训练图像，它就可以获得0.770的IoU，用于看不见的“灯光”类。注释管道生成高质量的掩码，平均IoU为0.883，与手动注释性能相当，但大大节省了时间。本研究通过引入一个可扩展的、资源高效的框架来促进可持续的CDW增值，该框架增强了特定类别的分割和简化了注释，在监督和少数镜头设置下都实现了高精度。

In few-shot scenarios, it attains an IoU of 0.770 for the unseen ‘lights’ class using only 20 training images. The annotation pipeline produces high-quality masks with an average IoU of 0.883, which is comparable to manual annotation performance but substantially less time-consuming. This study contributes to sustainable CDW valorization by introducing a scalable, resource-efficient framework that enhances class-specific segmentation and streamlines annotation, achieving high accuracy in both supervised and few-shot settings.</div></div>","PeriodicalId":23969,"journal":{"name":"Waste management","volume":"211 ","pages":"Article 115276"},"PeriodicalIF":7.1,"publicationDate":"2026-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145737667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The increasing demand for lithium-ion batteries (LIBs) and the consequential accumulation of waste from these batteries necessitate its appropriate disposal and recycling. This is important in order to responsibly address the environmental concerns and the shortage of critical metals such as lithium, nickel, cobalt, and manganese. The present study employs glycine, an environmentally friendly amino acid, as a leaching agent along with ascorbic acid, as a reducing agent, to recover valuable metals from spent LIB cathodes. The present study investigates the effect of time, temperature, pulp density, and reactant concentrations on the leaching process. Hydrothermal method integrated with machine learning (ML) approach reduced the number of experiments to reach the optimal leaching conditions. The study reports that at 2 mol/L glycine, 0.04 mol/L ascorbic acid, 75 °C temperature, 20 g/L pulp density, and 90 min reaction time, the leaching efficiency extends 91.0 %, 99.9 %, 92.3 % and 96.6 % of Ni, Mn, Co and Li, respectively. Additionally, glycine exhibits low leaching efficiency of Al, therefore, high purity aluminium can be recovered from the process.

对锂离子电池（LIBs）的需求不断增加，这些电池产生的废物也随之积累，因此需要对其进行适当的处理和回收。为了负责任地解决环境问题和锂、镍、钴和锰等关键金属的短缺，这一点很重要。本研究采用环境友好型氨基酸甘氨酸作为浸出剂，抗坏血酸作为还原剂，从废旧锂离子电池阴极中回收有价金属。本研究考察了时间、温度、矿浆密度和反应物浓度对浸出过程的影响。水热法与机器学习方法相结合，减少了实验次数，达到了最佳浸出条件。研究表明，在甘氨酸2 mol/L、抗坏血酸0.04 mol/L、温度75℃、矿浆密度20 g/L、反应时间90 min的条件下，Ni、Mn、Co和Li的浸出率分别提高了91.0%、99.9%、92.3%和96.6%。此外，甘氨酸对铝的浸出效率较低，因此可以从该工艺中回收高纯铝。

The growing quantity of flat panel displays (FPDs) on the market, combined with rising raw material demand, makes the sustainable management of resulting waste a hot topic. Despite of research often describes innovations in recycling, it often neglects the pre-treatment step. However, it represents a key aspect for the success of the further recovery of valuable fractions, since it affects the integrity of materials, the possible presence of impurities and hazardous substances, but also the sustainability of the whole recycling chain. In this regard, the present paper assesses the sustainability of two options implemented at real scale: a more traditional crushing (followed by magnetic separation) and an innovative solution which combines manual and robotic dismantling, resulting in the separation of high-quality fractions. The analysis, carried out by a life cycle approach, proves the high potential of the innovation from an environmental point of view with emission savings reaching up to 90% in key categories (e.g. climate change). The benefit, confirmed irrespective of the supplied energy mix and the classification of waste resulting from crushing (hazardous or not hazardous), is further highlighted by the possibility to separate high-value fractions, mainly printed circuit boards of three different qualities, based on their valuable metal content. The results represent an important driver towards the implementation of sustainable choices in the field of FPD recycling.

随着市场上平板显示器（fpd）数量的不断增长，加上原材料需求的不断增长，使得对由此产生的废物的可持续管理成为一个热门话题。尽管研究经常描述回收方面的创新，但往往忽略了预处理步骤。然而，它代表了有价值的馏分进一步回收成功的一个关键方面，因为它影响材料的完整性，杂质和有害物质的可能存在，以及整个回收链的可持续性。在这方面，本文评估了在实际规模上实施的两种选择的可持续性：一种更传统的破碎（随后是磁分离）和一种结合人工和机器人拆卸的创新解决方案，从而分离出高质量的分数。通过生命周期方法进行的分析，从环境的角度证明了创新的巨大潜力，在关键类别（例如气候变化）中减排高达90%。无论所提供的能源组合和破碎产生的废物分类（危险或无害）如何，这种好处都得到证实，进一步突出的是，可以根据其有价值的金属含量分离高价值的部分，主要是三种不同质量的印刷电路板。研究结果代表了在FPD回收领域实施可持续选择的重要驱动力。

In December 2019, the European Union announced the Green Deal as a growth strategy to ensure a resource-efficient and competitive economy. Based on this, in 2023 targets for battery recycling were formulated in a regulation. It is imperative to enhance both the recovery rate and the quality of the material to comply with this regulatory requirement. Two hydrometallurgical battery recycling processes for black mass from lithium-ion batteries with nickel manganese cobalt oxide 111 have been examined. The experimental investigation focuses on comparing early-stage lithium recovery (ESLR) process route, were lithium is leached in a first step with water from the black mass before acid leaching, with a reference route. Based on this analysis, an initial process simulation was developed in HSC SIM to generate data for life cycle assessment. Results show that the ESLR route increases lithium recovery to 61.9 % in experiments, with higher product quality. Simulation-based analysis showed a 5.7 % reduction in climate change impact per kg black mass treated compared to the reference route. Improved lithium recovery and quality reduced the climate impact of secondary lithium carbonate by 16 %, and by 37 % if wind power replaces grid electricity. Among sixteen impact categories evaluated, the ESLR route has lower impacts than the reference in thirteen categories.

2019年12月，欧盟宣布了《绿色协议》作为一项增长战略，以确保资源节约型和竞争性经济。在此基础上，制定了2023年电池回收目标的法规。为了满足这一法规要求，提高回收率和材料质量势在必行。研究了镍锰钴氧化物111锂离子电池黑质量的两种湿法冶金电池回收工艺。实验研究重点比较了酸浸前先用黑团水浸出锂的早期锂回收（ESLR）工艺路线与参考路线。基于此分析，在HSC SIM中开发了一个初始过程模拟，以生成生命周期评估的数据。结果表明，ESLR工艺可使锂回收率达到61.9%，产品质量较高。基于模拟的分析显示，与参考路线相比，每公斤黑质量处理的气候变化影响减少了5.7%。锂的回收和质量的提高将二次碳酸锂对气候的影响降低了16%，如果风力发电取代电网供电，将降低37%。在评估的16个影响类别中，ESLR路线在13个类别中的影响低于参考。

With the growing use of bioplastics due to their low environmental impact, interest in bioplastic-degrading microorganisms has also increased. To screen for such microorganisms, a clear zone test using plates containing bioplastic emulsions with detergents has been widely used as a key method for rapid and accurate identification. Although emulsifying detergents affect the hydrolytic activity of microbes, their effects have not been thoroughly evaluated across different detergent candidates. In this study, eight different detergents were evaluated for their effectiveness in screening poly(butylene adipate-co-terephthalate) (PBAT)-degrading strains. The anionic detergents N-Lauroylsarcosine sodium salt (Sarkosyl NL), sodium dodecyl sulfate (SDS), and non-ionic polysorbate 20 (Tween 20) enhanced clear zone formation. Among them, the non-ionic detergent Tween 20-based clear zone test system was the most effective for screening PBAT-degrading strains, showing rapid and distinct clear zone formation. This method was also applicable to polybutylene succinate (PBS), polycaprolactone (PCL), and polylactic acid (PLA). Using the Tween 20-based method, Bacillus sp. Y4 was isolated and exhibited a high PBAT degradation rate of 52 % over 14 days. Overall, this study demonstrated that the Tween 20-based clear zone assay offered a reliable and biologically stable screening platform.

由于生物塑料对环境的影响小，人们越来越多地使用它们，对生物塑料降解微生物的兴趣也在增加。为了筛选这类微生物，使用含有生物塑料乳剂的清洁区试验已被广泛使用，作为快速准确鉴定的关键方法。虽然乳化洗涤剂会影响微生物的水解活性，但它们的效果尚未在不同的洗涤剂候选物中得到彻底的评估。在这项研究中，评估了8种不同的洗涤剂对聚己二酸丁二酯（PBAT）降解菌的筛选效果。阴离子洗涤剂n-月桂酰肌氨酸钠盐（Sarkosyl NL）、十二烷基硫酸钠（SDS）和非离子聚山山酸酯20 （Tween 20）增强了透明带的形成。其中，以非离子型洗涤剂Tween 20为基础的清区检测系统对pbat降解菌的筛选效果最好，清区形成迅速、清晰。该方法也适用于聚丁二酸丁二烯（PBS）、聚己内酯（PCL）和聚乳酸（PLA）。采用基于Tween 20的方法，分离出芽孢杆菌Y4, 14 d内PBAT的降解率高达52%。总之，本研究表明，基于Tween 20的透明区试验提供了一个可靠的、生物学稳定的筛选平台。
