Using electric dryers reduces lifecycle emissions by 91 % or increases them by 223 %, depending on regional grid carbon intensity and dryer efficiency. As grids decarbonize, electrification benefits most regions by 2044. Full line drying eliminates lifecycle emissions, partial line drying cuts 56 %, and off-peak drying reduces 8 %. Efficiency upgrades and electrification increase lifecycle costs by $254–$721; partial line drying saves $262.

Identifying the locations and types of street-level dumpsites is a necessary first step for waste management; however, existing studies lack automated and accurate methods for detecting and categorizing these sites. As a result, governments face substantial labor and financial burdens in managing illegal dumping. To address these gaps, this study presents <em>MultiSense DumpSpotter</em>, a novel cascade model framework that integrates a multimodal deep learning architecture with Large Language Models (LLMs) to identify, classify, and analyze improper dumpsites with greater accuracy than traditional unimodal vision models. To support this framework, we developed <em>UrbanDumpSight</em>, the first annotated street-level urban dumpsite dataset, consisting of over 4000 street view images with metadata that includes geospatial and demographic information. This study contribute to the literature by demonstrating the effectiveness of multimodal data fusion in urban studies and the potential of LLMs in interpreting urban semantics. From a practical standpoint, it introduces a deployable, user-friendly system designed to meet the needs of urban managers, enabling efficient monitoring of improper dumping hotspots, uncovering root causes, and facilitating the implementation of effective governance actions. Overall, this research provides a novel and scalable solution for addressing urban waste challenges, offering insights to support sustainable waste management and policy-making.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"218 ","pages":"Article 108227"},"PeriodicalIF":11.2,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143579247","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, its feasibility for household mixed plastic waste has not been verified given the heterogeneous properties and mixed impurities, and how the impurities affect the process and products is also unclear. In this study, systematic field sampling was conducted and identified the composition and properties of 31 subfractions of household mixed plastic waste. Catalytic cracking experiments and carbon flow analysis were then performed to investigate the effects of various impurities on the yields and compositions of major products. Plastic impurities reduced the yield and carbon content of oil products to a moderate extent, but these effects were not magnified with the increase of the plastic impurity contents. Food waste impurities significantly reduced the oil products by 11 %–18 % and increased the oxygenated compounds and decreased the carbon contents, owing to the water and organic contents in the impurities. Metal impurity had marginal effects to the major products; while paper impurity contents showed a negative correlation with the oil product yields, as well as carbon and alkanes. This study demonstrates the feasibility of catalytic cracking for recycling household mixed plastic waste and its tolerance for most impurities. The results also imply that the removal of food waste impurities is important for ensuring high-quality targeted oil products for further utilization as a substitute of naphtha.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"218 ","pages":"Article 108235"},"PeriodicalIF":11.2,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143563684","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}

Industrialized and circular construction approaches hold promise for sustainability, especially by promoting building designs for easier disassembly and material recovery. However, assessing building deconstruction potential remains challenging, exacerbated by the interchangeable use of disassembly-related terms, leading to misunderstandings of deconstruction and its measurement. This study addresses these issues by proposing a Disassembly Ease Index (DEI) based on seventeen key variables identified through a comprehensive literature review. The DEI, tested in a case study, was found to be sensitive to factors such as connection types, required disassembly tools, and deconstruction methods, all of which significantly influence value retention options like reuse.

This paper fills this critical gap by evaluating 671 households in a randomised controlled trial (RCT) over seven months. This study implemented interventions, using principles of nudging and cognitive dissonance, to bridge the attitude-behaviour gap, measuring food waste and behaviours via online surveys.
