The state government will set up three more fly ash brick construction unit in three districts soon.
The initiative taken by Mamata Banerjee has earned popularity among self help groups run by women and funded by Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA).
Fly ash from thermal power stations is taken to the brick manufacturing units. As brick kilns often cause environmental pollution, a new machine has been designed where bricks are being constructed from fly ash without polluting nature.
The women who are members of the self help groups are given training to operate the machine. This has made the women economically self reliant.
The production cost of each brick is Rs 2. They are being used to construct rural roads and houses under various schemes. They are sold in the market at Rs 5 piece which is cheaper by Rs 3.
The first unit was set up in Bankura. Taking cue from the success of the unit, another unit is soon coming up in the district. Two units are functional in Chakdah block in Nadia and another one is coming up at Haringhata. A unit will be constructed at Tamluk in East Midnapore.
A senior state government official said the strength of the bricks made out of fly ash had been tested by IIT Kharagpur and the bricks are being used after getting clearance from IIT. The machines are easy to operate and the price varies anything between 5 lakh and Rs 20 lakh.
