The combustion of peat fuel for industrial scale power generation and domestic heating produces toxic ash, most of which is presently buried in landfill. In this study, the mineralogy of waste peat ash was determined, followed by its successful use as a starting reagent to prepare zeolites. X-ray diffraction (XRD) confirmed the presence of quartz, anhydrite, calcite, lime, merwinite and magnetite in peat ash, and that a single extraction step using mineral acid was sufficient to remove all non-quartz crystal phases. Alkali fusion of the acid-extracted samples produced GIS-type zeolite. LTA-and FAU-type were also prepared by altering the Si/Al ratio and extending the ageing time. Experiments confirmed that the LTA-and FAU-type zeolites were active in the simultaneous adsorption of lead, cadmium, cobalt, zinc and copper from aqueous solutions, with similar quantities of metals removed to those using a reference zeolite.

“…The literature data indicate their application in construction materials [32], synthetic zeolites [40], sorbents [9], and geopolymers [41]. In order to assess the flow of heavy metal to the environment from industrial wood ash and the direction of its application, the research of physicochemical properties and chemical composition of ash, morphology, and mapping elements in micro-regions (grains), fractionation, and mobility of metals using SEM/EDS, FT-IR, TG-DTG, FAS, and sequential extraction methods were performed.…”

“…In the last few years, CFA usage as a cheap source of aluminosilicate has attracted scientists who have shown the successful transformation of this waste material into zeolites [110]. These synthetic fly ashbased zeolites are synthesized by various chemical processes (hydrothermal, alkaline fusion-assisted hydrothermal process, multi-step treatment method, microwave irradiation and sonication approach) resulting in a more uniform and cleaner state than natural types in terms of their lattice structures, pore size, and cages in their aluminosilicate frameworks [111][112][113][114][115][116].…”

Coal fly ash (CFA) is generated during the combustion of coal for energy production. Many studies are based on its utilization as the most abundant, cheap aluminosilicate industrial residue, which is recognized as a risk for the environment and human health. The present review is focused on CFA origin, chemical properties, and its catalytic application for biodiesel production. The aluminosilicate nature and the presence of rare earth elements make CFA suitable for different adsorption, catalytic, and extraction processes for obtaining valuable products including alternative fuels and pure elements. However, the presence of toxic elements is a potential environmental problem, which should be solved in order to avoid soil, water, and air pollution. The most used modification methods are alkali activation, hydrothermal, and thermal treatment that improve the structural, morphological, and textural properties. The active catalytic form could be obtained by impregnation or ion exchange method. It was found that such synthesized materials have significant catalytic potential in the biofuel chemistry. In the case of biodiesel production, the high values of conversion or yield can be achieved under mild low-energy reaction conditions in the presence of low-cost waste-based catalysts.
