An innovative approach was presented to recycling aluminum-rich sludge from water treatment, alongside coal fly ash, into bricks for construction. By varying fly ash ratios (0–50 %) and firing temperatures (900–1200 °C), optimal conditions were determined: 1050 °C firing temperature and 30 %-50 % fly ash addition. The resulting bricks meet construction material standards, boasting compressive strength (>7 MPa), porosity (15–30 %), water absorption (10–20 %), and permeability (>1.0 × 10<sup>−2</sup> cm/s). Incorporating fly ash mitigates shrinkage and crack formation. Organic matter ignition in sludge during brick-making creates a porous structure, ideal for low-impact development like permeable pavements in sponge cities. This method promotes waste reduction, aluminum recycling, heavy metal stabilization, and sustainable urban development, offering a cost-effective solution for safe, permeable bricks.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":null,"pages":null},"PeriodicalIF":11.2,"publicationDate":"2024-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142359340","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}

Wind energy expansion in global forested areas has unclear impacts on local forests and ecosystem services. Due to a lack of information on internal road distribution and deployment dates, few studies have assessed forest disturbances caused by wind farms. Environmental issues like vegetation destruction and soil erosion may be overlooked. To address this, we integrated multi-source spaceborne observations to identify deployment dates and road distributions of forest wind farms and mapped related forest disturbances and soil erosion changes. Six global locations were tested, showing over 80 % accuracy. Disturbance intensity ranged from 1.5 to 6.5 ha/MW, with NDVI decreasing by 0.03 to 0.33 in disturbed forest regions. The average soil erosion increase per unit area due to road construction ranged from 24.74 to 274.33 t/hm<sup>−1</sup> <em>a</em><sup>−1</sup>, while wind turbine construction caused an average soil erosion increase ranging from 26.52 to 26.52 to 263.46 t/hm<sup>−1</sup> <em>a</em><sup>−1</sup>.

Previous studies synthesized hardened materials from low-quality sand using solvothermal processes, but reducing the reaction time, previously 24 h, is crucial for practicality. In this study, the effects of varying reaction times on hardening mechanisms were explored using several characterization techniques. The results indicate that the optimal reaction time, 6 h, significantly enhances compressive strength, exceeding 35 MPa, primarily due to the formation of microcline, potassium hydrogen silicate, and tetraethoxysilane. Additionally, the waste solution (ethanol) was recycled, achieving a high recycling rate that substantially reduced carbon emissions.
