Thermal Power Plants (TPPs) should develop a suitable mechanism for smooth supply of fly-ash generated as a residue during the course of their production, which can be best utilized in manufacturing of bricks for the construction industry, experts said during a seminar on ‘Fly-ash utilization in contemporary construction and entrepreneurship development’ being jointly organized by the Confederation of Indian Industries [CII] and State Pollution Control Board [SPCB] on Friday here.
According to the information available, there are around 363 fly-ash brick manufacturing units in 17 districts of Odisha at present.
“Fly-ash the utilization ratio of which hovers at 60% now, can be increased to 100% so that, these residues can be effectively used in various sectors including the construction sector, and, in turn could mitigate its hazardous impact on the environment” Secretary, micro, small and medium enterprises [MSME], Government of Odisha, Panchanan Das suggested in his deliberations.
As per the official data, there are around 33 industries in the state which generate fly-ash to the tune of around 24 million tones [MT] annually. In 2013-14 itself, 60% of the total fly-ash generated coming around 15 MT has been utilized, officials informed during the meeting.
It is to be noted that, the state government has asked the TPPs to ensure maximum utilization of fly-ash, without which they might lose permission to operate their plants, as decided during a meeting on ‘Utilization of fly-ash’ earlier in April this year.
The fly-ash has to be used in filling of pot holes, manufacturing of bricks and construction of roads besides, in areas like crop nutrition in agriculture, cement manufacturing etc. The government has in the past directed to stop use of red bricks in the areas where the TPPs are located and made it compulsory to use bricks made out of ashes.
“Government has also taken initiative to set up Fly-ash resource centers to monitor the progress of utilization of fly ash and study the environmental impact due to the disposal of fly ash,” senior environment scientist Dr D K Behera said.
In a high-level meeting under Odisha chief secretary Jugal kishore Mohapatra has already decided to give emphasis on promotion of fly ash brick manufacturing unit besides, third party audit to check the flow of fly ash from TPPs, he said.
Experts during the seminar has also threw light on the key issues like, promotion of fly-ash based construction materials manufacturing units, smooth availability of fly-ash for long term commitment, maintaining the quality of construction materials, market development, pro-active role of TPPs in entrepreneurship development and fly-ash management and utilization cell in TPPs during their deliberations on fly-ash utilization in the construction sector.
It is to be noted that, the Industrial Policy Resolution, 2007 envisages the micro, small and medium [MSME] enterprises to laid emphasis on utilization of fly-ash. Besides, the policy says to provide Rs 2 lakh incentive / concession to those industries manufacturing bricks as per the specification given in Bureau of Indian Standard Certification.
