By synthesizing multidimensional geospatial datasets spanning nature reserves, land use patterns, wind resource availability, transportation infrastructure, and grid connectivity, a comprehensive evaluation system was established. This system quantitatively integrates five critical dimensions: wind energy generation potential, demographic-economic electricity demand profiles, transportation network accessibility, power transmission capacity, and geomorphological characteristics. The proposed model achieves unprecedented macro-scale synergistic optimization of these interdependent factors, systematically elucidating the spatial configuration patterns of wind farm suitability across China. Furthermore, it provides a novel decision-support mechanism for scientifically-based site selection processes.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"222 ","pages":"Article 108455"},"PeriodicalIF":11.2,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144291420","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}

This surge stems from the widespread use of these materials in building, roads, and other infrastructure, which has raised increasing concerns about the “sand crisis” and environmental damages from overexploitation. Addressing such concerns requires understanding patterns of global and national sand and gravel cycles, yet this remains hitherto unexplored. Here, we quantified historical stocks and flows of sand and gravel in buildings and infrastructure in 184 world countries from 1970 to 2019. We show that global gravel consumption is more than twice that of global sand consumption, albeit with a more stable growth rate. However, in international trade, sand dominates, with trade volumes 1.9 times larger than those of gravel, and Singapore is the leading importer. This suggests that sand supply is more vulnerable to geopolitical and market fluctuations. Over the past decades, per capita sand in-use stocks have increased in nearly all countries, whereas per capita gravel in-use stocks have saturated or even declined in many industrialized countries. Asia accounted for half of global sand in-use stocks and China has a large share of gravel stocks in residential buildings, both reflecting the impact of urbanization mode. These insights can inform policies for securing sustainable aggregate supply chains, improving resource efficiency, and mitigating environmental risks associated with overexploitation.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"222 ","pages":"Article 108460"},"PeriodicalIF":11.2,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144279618","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 RL scenario outperformed the status quo, leading to a 7.04 % overall improvement in the equally weighted total score. It also exceeded a single-objective, heuristic management approach in profit and reliability, though slightly reducing sustainability. The RL model strategically reserves battery storage for peak renewable energy generation and extends water system operation to circumvent pumping constraints.

Venditti,&nbsp;Ronalds Gonzalez","doi":"10.1016/j.resconrec.2025.108428","DOIUrl":"10.1016/j.resconrec.2025.108428","url":null,"abstract":"<div><div>Per- and polyfluoroalkyl substances (PFAS) have played a critical role in the fiber-based industry for decades, primarily due to their ability to impart water and grease resistance to materials. However, increasing environmental and public health awareness has intensified regulatory scrutiny and driven a transition toward safer alternatives. Historically, the paper industry has depended on PFOA, PFOS, 6:2 FTOH, and PFBS to achieve the necessary barrier properties in food packaging, and these compounds continue to be detected in some products despite regulatory efforts to phase out PFAS. In the textile industry, over 72 distinct PFAS compounds have been identified, with PFOS and PFOA still prevalent. Similarly, in the hygiene products sector, FOA, 6:2 FTS, PFBA, and 6:2 diPAP have been detected in diapers, sanitary pads, and facemasks. Beyond legal liabilities for PFAS-related pollution, which have exceeded USD 54 million within the fiber-based industry, challenges linked to the disposal of PFAS-containing products, along with rising sustainability expectations from consumers, further intensify economic risks. Despite the comparable performance of emerging alternatives, treating paper with PFAS remains the most cost-effective option at USD 0.00012 per m². In contrast, the higher costs of biobased alternative coatings, ranging from USD 0.015 to 0.98 per m², could significantly impact cost structures unless the societal costs associated with PFAS pollution are accounted for. Estimates indicate that this transition could cost industry up to USD 12,500 million more than using PFAS treatments. Nonetheless, PFAS often deliver barrier performance that exceeds functional requirements in fiber-based products, particularly in single-use applications. Comparisons between PFAS and alternative technologies should therefore be based on the performance required for the intended application. Notably, major companies from the pulp and paper and textiles industries have already demonstrated that large-scale adoption of PFAS-free technologies is feasible while maintaining essential product performance. These findings indicate that with ongoing innovation and scaling, cost parity with PFAS-based products appears attainable.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"222 ","pages":"Article 108428"},"PeriodicalIF":11.2,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144279617","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}

Results showed that the compacted material had a compressive strength above 40 MPa without relying on hydration reactions. CaCO₃ grew on adjacent particles, became interconnected, and formed interparticle crystal bridges, shifting the mechanism of particle bonding from physical contact produced under pressure to chemical crystal bridge bonding.

Hence, understanding and addressing the influences of dyes, including those after bleaching, on extrudability and property of the regenerated textiles, and the importance of non-destructive dye removal are vital to the success of cotton recycling.

This paper develops a value chain analysis (VCA) model, with a consideration of value retaining processes (VRPs), which combines physical and monetary value flows of lithium (Li) for China’s lithium-ion batteries (LIBs) sector. The results indicate that the largest stages of value creation in China’s LIBs supply chain are Li chemicals refining and LIBs-powered products production, while an estimated economic loss happens at end-of-life (EOL). Results also highlight three main issues that affect value addition in the whole chain, including: (1) price volatility of upstream raw materials; (2) VRPs conducted at EOL; (3) international trade dynamics in the downstream LIBs and LIBs-powered products. Therefore, targeted policies to enhance CRMs traceability along LIBs value chain and stringent regulatory requirements for EOL recovery are needed to enhance resilience, maintain value, and sustainability.
