Fly ash bricks help reduce construction waste by utilizing the powdery by-product of burning coal. They are a green replacement for red clay bricks, which contribute to 5-15% of India’s emissions.

In comparison to red clay bricks, fly ash bricks are less expensive and the production process doesn’t emit smoke or use the more fertile top soil. Their use has been mandated by some regions and about 150 small fly ash enterprises have emerged.
