Fly ash bricks are made primarily from fly ash, a byproduct of coal combustion in thermal power plants. Instead of this material ending up in landfills, it’s repurposed into strong, durable bricks. The process involves mixing fly ash with lime, gypsum, and other additives, then moulding and curing the mixture.

The use of fly ash bricks addresses several environmental concerns:

• Waste Reduction: By utilising fly ash, a waste product, these bricks significantly reduce the amount of material sent to landfills.
• Lower Carbon Footprint: The production of fly ash bricks requires less energy compared to traditional clay bricks, resulting in lower CO2 emissions.
• Conservation of Natural Resources: Unlike clay bricks, which deplete topsoil, fly ash bricks preserve natural resources.
• Water Conservation: The manufacturing process of fly ash bricks uses less water than conventional bricks.
