Coal Ash

Coal ash is a byproduct of burning coal in power plants to generate electricity. It contains residues like fly ash and bottom ash, which are left behind after combustion. Rich in minerals such as silica, alumina, and iron, coal ash can be used in construction materials like concrete. However, it also contains contaminants like mercury, arsenic, and heavy metals that can pose environmental and health risks if not properly managed. Proper disposal or reuse is essential to prevent these toxins from polluting air, water, or soil.
