Coal gangue (CG), which is mainly generated during coal excavation, mining, and coal
washing, is an industrial solid waste that is recognized as an environmental pollutant. The …

The discharge and accumulation of coal-based solid waste have caused great harm to the
ecological environment recently. Coal-based solid wastes, such as coal gangue and fly ash …

Recently, the large-scale stock and pollution of solid waste has become a serious
environmental and economic problem. Upcycling the solid waste to produce porous …

Interstitial slurry rheology significantly influences the pore structure of chemically foamed
geopolymer foams (GPFs). However, the relationship between these two factors has not …

Coal gangue is an underused resource and there is a lack of its utilization in the green
economy. This work aims at the clean recovery of critical metals in coal gangue, with the …

Adsorption is a promising method to remove dyes, such as methylene blue, from
wastewater. In this study, a dynamic adsorption set-up was used to treat synthetic …

In this study, GP (geopolymer) and GTA (geopolymer/ZnTiO3/TiO2) geopolymeric materials
were prepared from metakaolin (MK) and characterized by X-ray diffraction (XRD), X-ray …

Alkali-activated foams are ceramic-like materials prepared at near-ambient temperature.
This study investigates them for point-of-use water disinfection, thus providing an alternative …

This study reports a potential approach for the valorization of glass waste (GW) that is mainly
composed of amorphous silica to prepare lightweight foamed glass (FG). The preparation of …

This study explores the influence of temperature–time conditions, surfactants, and varied
waste compositions on the curing of geopolymer gels, a foam formation with the properties …
