Aligned with the principles of Nature-Based Solutions and Zero Waste policies, recycling mining waste as soil amendments could concurrently restore degraded areas and reduce the disposal of mining waste. In this context, we aimed to remediate a post-mining soil primarily impacted by heavy metal pollution using an alkaline waste generated in dunite exploitation, either in combination with compost or independently in field conditions. The objectives were to minimize heavy metal(loid)s mobility (As, Cu, Cd, Ni, Pb, and Se), to improve soil health, and stimulate plant growth (phytoremediation, <i>Lolium perenne</i> L. was used). Results revealed that the combination of dunite and compost successfully reduced the concentrations of available Cu and Ni in the soil by more than four times, significantly enhanced soil properties, and promoted the harvest of a greater biomass. Additionally, <i>Lolium perenne</i> L. demonstrated phytostabilizing capacity for Cu and Ni in the soil treated with the amendments. In conclusion, the utilization of combined dunite-based and organic amendments proves to be a favorable strategy for restoring polluted post-mining soils.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"26 5","pages":"2971 - 2979"},"PeriodicalIF":2.7,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10163-024-02013-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141519342","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}

The objective of the present study is to analyze the effect of alkali-activated fly ash and eggshell powder on the durability of reference soft soil mix. The sodium silicate and sodium hydroxide solution were used to activate the precursors. The specimens, with varying percentages of precursors (10%, 20%, 30%, 40%, and 50%), were heated for 7 days at 25 °C, 50 °C, and 80 °C before subjecting to 12 wetting–drying cycles. The outcomes of the investigation show that the residual strength increases with the increase in geopolymer concentration following a similar pattern of 7-day compressive strength. A decrease in the weight loss of geopolymer-treated clay was detected for the specimens earlier cured at 50 °C. Further, the cost analysis suggested that the eggshell powder–fly ash geopolymer is a much cheaper binder than conventional cement concrete.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"26 5","pages":"2961 - 2970"},"PeriodicalIF":2.7,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141519344","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 paper investigates the treatment of AT by CaO, resulting in its complete physicochemical transformation into a dry powder with the characteristics of inorganic material. Waste characterization of AT and obtained powder (including metals, PAH, BTEX, total hydrocarbon content, and EN12457-4 leaching test), their comparative FT-IR and SEM–EDS analyses, and XRD analysis of the powder revealed that the transformation is a complex process involving Ca(OH)₂ formation, evaporation of water and BTEX, and degradation of aromatic and unsaturated hydrocarbons. The remained organic phase is encapsulated under Ca(OH)₂ and CaCO₃ layers forming “organic core—inorganic shell” micron-sized particles, rendering the powder suitable for further treatment. This was confirmed by solidification/stabilization treatment of AT and obtained powder using the same amount of cement and pozzolanic binder. In contrast to AT solidificates, the powder solidificates possess unconfined compressive strength above the required value and characteristics of inert waste.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"26 5","pages":"2947 - 2960"},"PeriodicalIF":2.7,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141509490","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 paper reviews the utilization of porous glass, particularly made from recycled waste glass, for manufacturing and environmental applications. Porous glass features a broad size range of tiny pores, offering advantages in recycling due to its inertness, sorption capabilities, and versatility. It can be produced through phase separation, sol–gel, hydrothermal methods, and the use of foaming agents, offering a large surface area and high sorption efficiency. The adsorption capacity, flexibility in enhancing material properties, and reusability of porous glass allow it to be applied in diverse environmental roles, such as contaminant removal from water and wastewater. The controlled release of phosphate from phosphate-porous glass adsorbent enables its use in fertilizing plants while minimizing excess phosphate release into the water bodies. Its unique physicochemical properties also make it suitable for use in construction sectors. Our findings highlight the porous glass's potential to significantly contribute to glass recycling, reduce landfill airspace, and support sustainable material usage.

Due to calcium and phosphorus in its structure, PG can be evaluated for synthetic hydroxyapatite (HAp) production. This study provides a two-step reaction sequence for PG-derived synthetic HAp production. Synthesized HAp (s-HAp) particles were calcined at 900 °C for 4 h, followed by characterization studies with respect to commercial bone ash (CBA) sample to be evaluated as its substitute in bone china industry. Ca/P ratio (wt%) of the samples was investigated by microwave-assisted temperature-controlled acid digestion, followed by ICP-OES analysis. Crystallinity of the samples was analyzed by XRD, and morphological structure was investigated by SEM–EDS analyses. ICP–OES analyses revealed that s-HAp and CBA samples have similar Ca/P ratio, 2.0979 for s-HAp and 2.0917 for CBA samples, respectively. Low-intensity β-TCP phases in the XRD patterns of s-HAp samples revealed low crystalline structure. SEM images indicated a uniform distribution with spherical-like morphology in CBA samples, however, a layer-by-layer morphology and amorphous structure was observed in s-HAP samples. Structural and morphological differences indicate that PG-derived s-HAp samples require purification processes and reaction parameters should be further developed to increase yield. However, this study provides a high potential for a novel approach of an industrial scale valorization strategy for PG. Because the supply–demand cycle is price dependent, the availability of phosphorus in agriculture as a raw material has been a major concern for the usage of phosphate rock. Novel methods for substitute supplies of phosphorus in agricultural applications have been suggested. While HAp is a common ceramic material, its application as a substitute for phosphorus fertilizer is still in its infancy. PG has great potential as a raw material for the synthesis of hydroxyapatite and ammonium sulfate. Large-scale PG production in the phosphoric acid industry puts pressure on research to develop alternate methods for using PG aggregate resources in an economical and environmentally responsible way. The use of PG as a calcium and phosphorus precursor in the synthesis of HAp will result in an economical raw material and an effective waste management plan.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"26 5","pages":"2770 - 2780"},"PeriodicalIF":2.7,"publicationDate":"2024-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141335640","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}
