In this study, nitric acid (HNO<sub>3</sub>) was employed to extract P from sludge-incinerated bottom ash and nitrogen–phosphorus (N-P) compound fertilizer was synthesized by adding aqueous ammonia to the P-rich extract. The N-P compound fertilizer was continued to be applied to the cultivation of ryegrass, and the impact on plants and soil was analyzed. The results indicated that the optimal concentration of HNO<sub>3</sub> was 5.0 mol/L and 93.1% of P in sludge-incinerated bottom ash could be recovered in HNO<sub>3</sub> extraction. The N–P compound fertilizer prepared after ammonia neutralization exhibited an amorphous complex composed of various substances. The Ca, Mg, Al, and Fe contents of N-P compound fertilizer were 813, 220, 137, and 25 mg/kg, respectively. N–P compound fertilizer enhanced ryegrass growth; after 20 days of planting, the root, stem, and leaf length were 2.0, 1.3, and 1.4 times that of the control, respectively. N–P compound fertilizer did not lead to heavy metal accumulation in plants and soil deterioration after fertilization.

Conventional disposal methods such as landfilling without any prior treatment lack long-term sustainability and safety. In this study, we explore the application of geopolymers as a green binder for the solidification and stabilization (S/S) of asbestos-containing waste (ACW) prior to its final disposal into scientific landfill sites to mitigate environmental and health hazards. Geopolymer–asbestos blocks were developed using class F fly ash and alkaline activators. Compressive strength tests revealed that the geopolymer–asbestos blocks exhibited strengths exceeding 8 MPa, making them suitable for safe disposal in landfill facilities. The ideal asbestos content for achieving substantial compressive strength was found to be between 5 and 15% (w/w). Microstructural analysis confirmed the entrapment of asbestos fibres within the geopolymer matrix, enhancing structural integrity. XRD analysis identified quartz as the major mineral phase, with traces of other minerals. Leaching studies demonstrated effective immobilization of toxic metals, such as chromium and lead, within the geopolymeric structure. The absence of heavy metals in leachate samples indicated the efficiency of geopolymer-based S/S in preventing environmental contamination. This study suggests that geopolymerization offers a promising approach for the environmentally sound disposal of asbestos-containing wastes, providing a viable interim solution until the complete cessation of asbestos use in many countries across the globe.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 1","pages":"75 - 90"},"PeriodicalIF":2.7,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142939347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Initially, the phosphor powder with a particle size of less than 45 µm was dissolved in a 4 M HNO3 solution, followed by Ca precipitation using Na2SO4.

For the stripping step, the effect of the stripping agent (HCl, HNO<sub>3</sub>) on the selective recovery of Y (> 99% purity) or Y–Eu oxides was examined. At the pH value of 0.05, 20% ligand concentration, and 1:1 O: A ratio for 10 min, 88.50% of Y was selectively transferred to the organic phase (D2EHPA) in one step, leaving a considerable amount of Eu remained in the raffinate.
