Addressing the plastic waste challenge through chemically upcycling waste to other products is gaining momentum but can have trade-offs. For example, the conversion of plastic waste into hydrogen rich gas can be achieved via catalytic steam, but this process can release large quantities of CO2 (∼12 kg CO2 per 1 kg H2 production). High-performance bifunctional catalysts, such as carbon nanotubes (CNTs), offer a potential solution, but suppressing CO2 emissions without compromising H2-rich gas yield remains challenging. Here, we synthesize a new CNTs-bridging nanocomposite by integrating Ni nanoparticles with HY zeolite. Employing this bifunctional CNTs-bridging nanocomposite in the catalytic steam reforming of polyethylene can achieve high-quality H2 yields of up to 2,340 mL/gplastic and a 77% reduction in CO2 emissions (1.68 g CO2 per 1 g H2 production). This work introduces an innovative CNTs-bridging strategy to valorize plastic waste into high-quality H2-rich syngas while suppressing CO2 emissions.","PeriodicalId":52366,"journal":{"name":"One Earth","volume":"27 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140886195","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}

However, current estimates of LUC-induced emissions vary widely with differences in data and models, making it challenging to identify and manage emissions hotspots by location and LUC activity. Here, we estimated spatially explicit carbon fluxes associated with global major gross land-use transitions based on a new bookkeeping model (i.e., LUCE). Between 1961 and 2020, LUC induced 215 and 142 Pg C of global carbon emissions and removals, respectively, resulting in average net emissions (ELUC) of 1.21 Pg C year−1. Latin America, Southeast Asia, and Sub-Saharan Africa dominated global ELUC with 69% of 60-year cumulative emissions, or about 86% between 2001 and 2020. Forest-related LUC activities (e.g., deforestation, reforestation) contributed largely to both regional and global carbon fluxes. Our findings shed new light on identifying LUC-induced emissions hotspots and managing land for climate mitigation and conservation.","PeriodicalId":52366,"journal":{"name":"One Earth","volume":"81 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2024-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140828464","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}

Colonization of restored sites by non-habitat-forming animals improves outcomes for ecosystems and society, yet there has been no review of how animals respond to coastal restoration. Here, we extracted 5,133 response ratios from 160 studies to show how coastal ecosystem restoration benefits animals as individuals, populations, and communities. Abundances and diversity at restored sites were greater than at degraded (61% and 35%, respectively) and unstructured (42% and 37%) control sites and similar to those at natural reference sites (both within 2%). Individuals in restored sites were similar in condition to those within control and reference sites. However, responses among projects were highly variable and rarely related to restored site maturity or characteristics, presenting a challenge for predicting outcomes and highlighting the need to improve restoration techniques, monitoring, and reporting. Nevertheless, studies so far suggest coastal restoration benefits biodiversity.","PeriodicalId":52366,"journal":{"name":"One Earth","volume":"95 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140636266","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}
