While artificial upwelling (AU) has been shown to enhance nutrient availability and boost seaweed production in marine ecosystems, the potential of AU-enhanced seaweed cultivation to act as a carbon sink remains poorly understood. Here, we develop a comprehensive framework to estimate the carbon sink potential of AU-enhanced seaweed aquaculture in coastal China. We first quantify environmental suitability for AU projects by creating a composite coefficient (<em>K</em><sub>AU</sub>, unitless) based on engineering constraints. Using the best-performing predictive model among four candidates, we then estimate the additional aquaculture area that could be supported by AU (<em>E</em><sub>AU</sub>). Finally, we combine area-to-yield conversion equations with China’s marine carbon sink accounting method (HY/T 0349–2022) to project carbon sequestration potential. Our analysis identifies suitable AU project sites across 5 provinces, 8 cities, and 11 counties or districts in coastal China. The AU is projected to expand at 3591 km<sup>2</sup>/yr (2022–2027), representing a 2.5-fold increase over the 2022 baseline, with the expanded areas demonstrating substantial carbon sink capacity (861 656 tonnes/yr), which is equivalent to 99.3 % of the 2022 total. Zhejiang Province emerges as the dominant contributor, accounting for over half of the additional aquaculture area, with <em>Porphyra</em> providing the largest carbon sink contribution. Our quantitative framework provides a foundation for evaluating and optimizing AU deployment strategies for climate change mitigation through marine carbon sinks.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"222 ","pages":"Article 108468"},"PeriodicalIF":11.2,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144330403","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}

Pursuant to these goals the authors have developed ‘T-reX’, an analytical tool for LCA, written in Python. T-reX extends on the existing computational ecosystem centred on Brightway and Premise and can facilitate the quantification of user-defined supply chain demands for activities in current and prospective scenarios. T-reX streamlines database manipulation for LCA practitioners, integrating methods to aggregate and analyse demand inventories that could expose hotspots of hidden risk. With a simple case study using lithium-ion batteries, we demonstrate some of T-reX’s potential by detailing and exploring aspects of their waste and material footprints.

The limitations of alternative materials, such as the deterioration of flame retardant polymers, increased foaming, and decreased quality of alternatives for photovoltaic glass, further exacerbate reliance on antimony. The diverse end uses of antimony result in its recycling being challenging. Furthermore, its accelerated demand is rapidly depleting its reserve. Therefore, the surging demand for antimony driven by the energy transition raises concerns regarding supply security and resource efficiency. The present study employed material flow analysis to examine global antimony flows from 2000 to 2050. It aims to evaluate how improved recycling strategies can reduce reliance on primary mining and enhance supply security under various energy transition scenarios. The results indicated significant demand growth, particularly for photovoltaic glass (13.8-fold growth) between 2010 and 2022, and that supply risks would persist owing to low recycling rates (8.5 %). The scenario analysis showed that increasing recycling rate would reduce dependence on primary mining. Additionally, recycling potential varied regionally, with countries in North America and the European Union being more self-sufficient and other countries relying heavily on primary supply, necessitating policy intervention and investment in collection systems. Collectively, our results show that enhanced recycling aligns with circular economic principles, mitigates resource depletion, and improves long-term supply security.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"222 ","pages":"Article 108432"},"PeriodicalIF":11.2,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144297300","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}
