Over the years, the production of waste ash from many sources (eg coal, biomass, industrial,
animal, and municipal solid waste) and from conventional and renewable energy …

Soil pollution is an increasingly urgent problem for the global environment. Soil can be
contaminated with potential toxic metals from many anthropogenic activities, besides fossil …

Synthetic zeolites obtained combining natural sources (bauxite and obsidian), pure
alumina/silica reagents, and waste material (red mud) were tested for heavy metals (ie, Pb …

Coal fly ash (CFA) is fine particles generated from coal combustion, and large amount of
CFA causes environmental pollution. Traditionally, CFA is added into construction materials …

Zeolite synthesis typically requires batch systems (precursor mixture) in which aluminate
and silicate solutions are first mixed and then subjected to hydrothermal treatment. In this …

Mt. Etna, the largest volcano in Europe, is periodically interested by intensive eruption
activity sometimes causing environmental problems for the neighbouring urban areas such …

The action of direct sonication (US) versus conventional hydrothermal method (HY) was
investigated to determine the differences in the crystallization mechanism of zeolite formed …

Zeolites can be extensively employed in agricultural activities because they improve soil
properties such as infiltration rates, saturated hydraulic conductivity, water holding capacity …

The addition of natural or synthetic zeolites alters a soil's chemical, physical and biological
properties. Due to the existence of a complex internal structure, zeolites have the potential to …

Burning of coal accounts for an enormous proportion of the current energy supply, especially
in developing countries. Burning of coal produces large amounts of coal fly ash, which …
