The FAL-G project aims to promote fly ash bricks as an alternative to burnt clay brick with in the construction sector in India. Fly ash, the key ingredient of FAL-G technology, is a waste product from thermal power plants and is abundantly available in India. Fly ash is mixed with two chemical plants. This is proving to be a revolutionary invention that produces bricks without the sintering process meaning no energy is required in this process and consequently no greenhouse gases are emitted.

Many government departments, including the Central Public Work Department and state housing agencies, use FAL-G bricks. But even with more than 1,200 FAL-G Brick making units operating throughout India, brick production from FAL-G operators is still a tiny fraction compared to that of clay brick producers 2million FAL-g bricks a year versus hundereds of billions of clay bricks a year.
