Manufacturing of bricks is usually associated with several hazardous activities such as damaging the agricultural land by cutting down the top soil or burning woods, tires and rubber, which are quite harmful for the environment.

However, it is not the case with a brick kiln in Thakurgaon. There, modern machinery is being used to make eco-friendly bricks from fly ash, cement, sand and stone chips.

The Bablu Super Bricks Industry Limited is a sister concern of Razzak Group in Parpugi village in Thakurgaon Sadar upazila. The authorities concerned claim that this is the first factory in the country to make bricks with fly ash.

Fly ash, sand, cement and stone chips are being mixed in a certain ratio in this machine. And then, pressure is applied to made the bricks. There is no need to burn the bricks at all.

Habibul Islam, chairman of the Razzak Group said, “There is no alternative to eco-friendly bricks to save the environment. From this vision, I started this factory.”

According to the officials and the staff of the company, Habibul has to travel abroad a lot for business related works and during one such trip he first noticed the eco-friendly bricks. Later, he planned for making eco-friendly bricks in the country. He went for manufacturing on 19 November last year.

In this factory, every brick is manufactured by using 40 per cent of fly ash, 4 per cent of sand, 15 per cent of cement and 5 per cent of stone chips. The vibro cavity machine can make 8,000-20,000 bricks every eight hours.
