This study proposes a tailored P recovery strategy from PAWW based on a dual-module flow electrode capacitive deionization (FCDI) system, which includes a P recovery module and a desalination module. The dual-module FCDI system efficiently separates P from impurities in simulated PAWW, through unique flow electrode circulations. And it demonstrates reasonable electrical energy consumption for P recovery of 2.45 kWh/kg P (constant voltage of 1.2 V). Over a continuous operation of the dual-module FCDI system for approximately 26.5 h, a P-enriched solution (8298 mg P/L) is successfully recovered from simulated PAWW, and then high-purity vivianite (Fe₃(PO₄)₂‧8H₂O) product is synthesized. The P recovery efficiency of the whole process reaches 78.66 %. This study provides an environmentally friendly strategy to recover P from PAWW based on FCDI technology.</p></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":null,"pages":null},"PeriodicalIF":11.2,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141953418","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}

To accurately assess the performance of URSCFs, it is crucial to quantify their environmental and economic impacts. However, previous studies have predominantly focused on location-specific case studies, lacking a macro-level perspective necessary for informing public policy development pertaining to SC initiatives. This study aims to bridge this gap by conducting a macro-level life cycle assessment across China's 16 initial pilot SCs, categorized into three zones based on their annual rainfall volume control rate α (i.e., Zone II (80 % to 85 % for α), Zone III (75 % to 85 % for α), and Zone IV (70 % to 85 % for α)). By simulating five rainfall drainage scenarios, we delve into the environmental benefits of SC construction. The results indicate that Zone III incurs the highest environmental and economic costs during the construction phase, followed by Zones II and IV. In Zone III, bioretention contribute significantly to the environmental impact and economic cost, while constructed wetland and detention cells are the key contributors for Zone II. During the operation phase, Zone III demonstrates the largest environmental and economic benefits, with Zone IV and II trailing behind. The investment payback period for SCs in all zones is less than eight years, with Zone IV recovering costs the fastest (3.9 years) and Zone II the slowest (7.5 years). Facilities like detention cells, green roofs, and permeable pavements tend to have longer payback periods. Based on our findings, we recommend that Zone II exercise caution in constructing detention cells, permeable pavements, and wetlands, while Zone III should carefully consider green roofs and bioretention to optimize SC investments. Due to the fewer URSCFs constructed in Zone IV, it exhibits the lowest environmental impact compared to Zones II and III. Our research provides valuable insights to support policymaking with regards to future SC planning and development.</p></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":null,"pages":null},"PeriodicalIF":11.2,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141953419","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}

Particularly, it is widely acknowledged that social networks, usually represented by psychological closeness/distances in literature, can influence others’ behavior via sharing information and opinions. However, given the theory of behavioral contagion, geographic networks provide channels to directly observe others’ behavior and to further adapt self-behavior even in the absence of social networks. Despite this, a systematic analysis of how geographic networks affect waste disposal behavior is still lacking. Using the coordinates of the households surveyed in this study, we measure geographic networks by physical distances among household residences and distinguish the roles of geographic and social networks in shaping waste disposal behavior (including domestic waste sorting, agricultural waste disposal, sewage collection, and toilet retrofitting) by Bayesian estimation of a spatial autoregressive probit model. Besides confirming positive impacts of social networks, this empirical analysis reveals that pro-environmental waste disposal behavior spreads via geographic networks among neighboring households. More importantly, the intensity of this behavioral contagion varies between different types of waste disposal behavior due to heterogenous socio-economic characteristics.</p></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":null,"pages":null},"PeriodicalIF":11.2,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0921344924004476/pdfft?md5=97cde9231fa91a79cfb18fe86b78153f&pid=1-s2.0-S0921344924004476-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141963220","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}
