Here we leverage the diverse composition of urban mines to develop ‘reciprocal recycling’—a self-assembly strategy that uses urban mine components to support their own recycling to ultimately activate sustainable urban mining. We screened tens of physicochemical componential interactions available for multimetal co-recovery, halogenated pollutants elimination and polymer conversion. Self-assembly prototypes with four fundamental componential interactions were presented for reciprocal recycling of representative urban mines. Under the guidance of revealed physicochemical interaction mechanisms, the reciprocal recycling process design enabled >96% recovery of copper–platinum–palladium–rhodium, >99% suppression of brominated pollutants and mediated epoxy resin conversion. The self-assembly strategy showcased joint environmental–economic–efficiency benefits and high flexibility, paving the way to sustainable urban mining and improving material circularity. Urban mining is crucial for improving the sustainability of materials cycle but hindered by the complexity of urban mine composition. Here the authors develop a self-assembly strategy that takes advantage of the composition diversity of urban mines to achieve sustainable reciprocal urban mining.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 9","pages":"1026-1036"},"PeriodicalIF":27.1,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 conventional production and use of solid nitrogenous fertilizers results in substantial energy consumption and severe groundwater pollution. Here we propose an absorption‒electroreduction relay strategy capable of the distributed production of directly accessible liquid N fertilizer (NH4NO3 solution) from NOx, a common constituent of exhaust gases. When combined with plasma-driven N fixation, the raw feedstock in this strategy can be further extended to air. NOx is first absorbed by an aqueous solution. The NOx− produced as well as the residual NOx are selectively reduced to NH4NO3 by a ruthenium‒cobalt electrocatalyst (Ru9Co91). Through the N balance established between the absorption and electroreduction processes, NH4NO3 solutions are produced continuously without any other additive ions. We successfully constructed an 8-l membrane-free system that outputs 8.5 l h−1 of NH4NO3 solution at a constant concentration (840 mg l−1 of N) to meet the N fertilizer requirements for 20 m2 of farmland. This work offers an alternative route for obtaining N fertilizers, with the potential to improve the sustainability of the N fertilizer supply. Exploring alternative nitrogen (N) fertilizer production routes is crucial to improve the sustainability of the N fertilizer supply. Here the authors develop an absorption‒electroreduction relay strategy capable of the distributed production of liquid N fertilizer from NOx or even air.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 9","pages":"1068-1076"},"PeriodicalIF":27.1,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Management frameworks typically address non-target catch with fleet-level controls on fishing. Yet, individual operators differ in their fishing practices and efficiency at catching fish. If operators have differing abilities to target, they should also have differing abilities to avoid bycatch. To evaluate the generality of this pattern, we analysed variations in threatened species bycatch among individual operators from five industrial fisheries in Australia representing different geographic areas, gear types and target species. The individual vessel is a significant predictor of interaction rates in all 15 cases, including species that represent high or low costs to fishers, or have economic value. Encouragingly, we found high-target and low-bycatch vessels in all five fisheries, including gears often perceived as indiscriminate in the species they catch. The patterns of variation we find in the Australian fisheries data highlight the potential to reduce bycatch using measures focused on specific performance groups of individuals, offering an alternative approach that can complement fleet-wide controls. Fisheries bycatch, responsible for the decline of many threatened marine species, is managed with fleet-level controls, but individual operators’ ability to avoid bycatch differs. This study analyses variations in threatened species bycatch among operators from industrial fisheries in Australia.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 8","pages":"871-881"},"PeriodicalIF":27.1,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Retaining trees in agricultural systems is one proposed solution, but the magnitude of the current and future potential benefit that trees contribute to climate change mitigation remains uncertain. Here we help to resolve these issues across a West African region that produces ~60% of the world’s cocoa, a crop contributing one of the highest carbon footprints of all foods. Using machine learning, we mapped shade-tree cover and carbon stocks across the region and found that the existing average shade-tree cover is low (~13%) and poorly aligned with climate threats. Yet, increasing shade-tree cover to a minimum of 30% could sequester an additional 307 MtCO2e, enough to offset ~167% of contemporary cocoa-related emissions in Ghana and Côte d’Ivoire—without reducing production. Our approach is transferable to other shade-grown crops and aligns with emerging carbon market and sustainability reporting frameworks. Western Africa is one of the world’s largest cocoa-producing regions, with just two countries supplying up to 60% of global production, but at a high carbon cost. Incorporating shade trees into cocoa farms offsets the industry’s carbon cost, but existing coverage is low. Expanding coverage could substantially boost carbon stocks without reducing yield.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 9","pages":"994-1003"},"PeriodicalIF":27.1,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Several approaches attempt to address this purpose, but their adoption is dependent on available resources. While nations in the global south struggle with waste collection and rely heavily on open dumping, those in the global north invest in more advanced technologies to divert materials from disposal to recovery. To address cross-border waste concerns, a more in-depth understanding of the cost–benefit relationship of different strategies is required. Here we show that investment in advancing the waste infrastructure of the global south achieves a higher mitigation of greenhouse gas emissions and marine plastics than further upgrades in the global north. Basic collection is the essential step to reducing marine plastics, and a transition from open dumps and burning to controlled landfills does more to reduce methane and black carbon emissions than upgrading existing systems to advanced technologies. Our results demonstrate how targeted expenditures towards basic infrastructure components in those areas with the least investment are a more efficient use of global resources for mitigating climate change and reducing marine plastics. Solid waste can impact public health, climate change and ocean pollution, yet many countries lack basic infrastructure to manage it. A study now shows that investing in simple waste systems in lower-income countries delivers greater co-benefits than upgrading high-tech systems in wealthier ones.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 8","pages":"936-946"},"PeriodicalIF":27.1,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
