The phosphogypsum was pretreated by wet neutralization and dry neutralization respectively, followed by calcination at medium temperature to obtain II-anhydrite. XRD, XRF, SEM, FTIR, and other techniques were applied for analysis of the impact of these two pretreatments on impurity removal as well as their effects on the properties of calcined II-anhydrite. Then, the calcination process was optimized to reduce calcination energy consumption. The results show that the reaction between phosphorus and lime is superior to fluorine in the process of neutralizing. When the lime content reaches 1.4%, wet pretreatment can effectively remove soluble phosphorus and fluorine, promote the release and reaction of eutectic phosphorus during calcination, and then significantly improve the performance of II-anhydrite. However, dry pretreatment has no such effect. By combining lime neutralization and calcination at 500℃, the harmful impurities in phosphogypsum are removed. Compared with no pretreatment and dry treatment, wet pretreatment shortened the setting time of II-anhydrite by 45% and 29% and increased the three-day compressive strength by 252% and 161%, respectively.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 3","pages":"1914 - 1931"},"PeriodicalIF":2.7,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861248","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}

This study aims to assess the feasibility of transforming solid waste derived from the flat glass (WGP) and anodized aluminum (RAA) industries into zeolite materials. Zeolites are microporous crystalline materials widely used in petrochemical, catalysis and adsorption. Using a facile approach of combined alkaline fusion and hydrothermal treatment and fine-tuning operational (Si/Al ratio, basicity, aging time, temperature), we obtained five different zeolitic structures: LTA, FAU, GIS, CAN, and SOD. Higher Si/Al ratios tend to form more structurally condensed zeolites. Conversely, extended aging periods and elevated temperatures promote the crystallization of thermodynamically more stable zeolite phases. The overall process yield was ~ 50% (w/w) leading to FAU zeolite with an average particle size of 278 nm, specific area of 181 m² g⁻¹ and pore size distribution of 17–63 nm when Si/Al = 6 and 24 h of hydrothermal treatment.

This study has developed a technology incorporating chemical reagents to enhance hydro-cyclone separation efficiency. Including these reagents significantly improves the separation effect of sand-clay mixture samples, via sedimentation experiments. A corresponding reagent index evaluation method has been proposed, determining the optimal reagents from three dimensions separation efficiency, reagent concentration, and pH value. These reagents are then subsequently applied to the hydro-cyclone device. The results show that samples added with polycarboxylate can achieve a maximum sand resource separation efficiency of 95.7%. Compared to the sand extraction efficiency without added reagents, the maximum sand extraction efficiency increased by 1.4 times. Predictive equations for sand extraction efficiency and applicable technological processes have been proposed for waste soils to facilitate the application of the technology.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 3","pages":"1885 - 1900"},"PeriodicalIF":2.7,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861246","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}

The effects of multiple recycle loops on unbleached kraft softwood (UBKP), semi-chemical hardwood (SCHW) and wheat straw (WS) pulps were evaluated for a packaging system in this study. The lab-scale recycle loops included mechanical refining to represent mechanical actions that can break fibers and papermaking. This allows in the experiments for the loss of fine fiber material in handsheet making; both breakdown and losses occur during paper recycling. Physical paper properties over multiple recycle loops showed paper strength with wood and non-wood fibers is not the limiting factor for the reuse of paper. After a moderate decline in properties on the first recycle, the paper properties remained constant over multiple recycles. The lab-scale average fiber yield for UBKP was 97% and for SCHW was 91% per cycle, whereas, for WS it was lower than 70%. These differences in yields are critical for understanding how fibers behave in paper recycling and are explained in part by fiber morphology and property differences.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 3","pages":"1901 - 1913"},"PeriodicalIF":2.7,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10163-025-02227-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Flash calcination is a heat thermal technique used to eliminate pollutants and organic content in excavated soils and allow them to be used in cementitious formulations. To develop GPC, the materials used in the development of the GP precursor binder should be rich in silicon (Si) and Aluminum (Al) that can react with alkaline silicates to yield Si–O–Al bonds that would form cementitious materials. The GP precursor binder is composed of Metakaolin (MK), flash-calcined soils, and granulated blast furnace slag (GBFS). The thermally treated soils are flash-calcined dredged sediments (FCS) and flash-calcined excavated clays (FCC) while potassium silicate is used as the alkaline reagent. This study aims to use the materials above to develop GPC cured under ambient conditions with high strength, good durability, and microstructure properties. Seven formulations are done to evaluate the effect of replacing MK with either FCS or FCC and GBFS on the mechanical compressive strength, water absorption, and freeze–thaw test. The findings reveal that using only metakaolin (MK0) in the formulation yielded the highest compressive strength. These results align with the porosity test outcomes, which show correlations between micropore and macropore percentages. Analysis of the durability freeze–thaw test suggests that as the proportion of macropores increases, formulations incorporating FCS and FCC exhibit improved resistance to extreme temperatures. Conversely, an increase in GBFS content leads to a finer microstructure and reduced resistance. Water absorption testing indicates that formulations with FCS and FCC display favorable sorptivity coefficients compared to MK0, with increased GBFS content enhancing durability. SEM/EDS and calorimetry tests were conducted to investigate the impact of substituting FCS and FCC for MK within the geopolymer matrix.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 3","pages":"1854 - 1872"},"PeriodicalIF":2.7,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861180","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}

In experiments, adsorption performance was assessed as a function of synthesis temperature (303–323 K), contact time (1–180 min), and sorbent dosage (1–6 g L⁻¹).

The proposed waste management starts with segregating food waste from other wastes carried out by each AYCE restaurant.
