It will also provide a platform for creating greater awareness about new technologies and innovations in the use of fly ash. I will provide an effective forum for the transfer of information and new ideas to benefit the innovative utilization, handling, storage and disposal of Fly ash.
With greater emphasis on implementation of Gazette Notification on fly ash for various uses, this conference is extremely relevant and beneficial.
The attendees include national wide representative from academia, industry, and government. A good number of scientist, environmental, fly ash management companies from across the country have confirmed their participations. Experts have confirmed their participation and talk on issue of fly ash and slag management.
About the Theme: “Fly Ash: Wealth from Waste”
Fly ash being considered a waste few years back, has converted itself into wealth, as a usable, valuable resource by establishing viable avenues for fly ash management. In other words, previously fly ash was looked upon as a waste and a pollutant. The perception has undergone considerable change over the past few years. Now Fly ash -a “waste material” considered a “resource material”.
The past decade has witnessed a significant growth in the technologies level w.r.t. fly ash disposal and utilization in the country and this millennium fly ash is itself is going to emerge as major industry.
There are lots of uses of Fly Ash. It is multipurpose resource. Fly ash from coal fired Thermal power plants is an excellent material for the manufacture of various construction materials like fly ash bricks, mosaic tiles and hollow blocks.
The manufacture of conventional clay bricks requires the consumption of large amounts of clay. These deplete top soil and leads to degradation of land.
Why National Conference
The National conference would bring to the fore on one hand the cascading effect of the fast growing power sector resulting in large volumes of fly ash, and on the other hand the well demonstrated and proven solutions that fly ash and its products provide for mine stowing / backfilling and stabilization / a forestation of OB dumps.
Bulk transportation & conveying of fly ashes as well as Statutory and Policy aspects including MoEF notification of 3rd November 2009 making use of fly ash mandatory in back filling of open cast mines & stowing of fly ash in underground mines would also be the focus of the conference.
The use of fly ash technologies and products in different sectors would not only overcome the raw material shortage situations but would help to augment the production, reduce the cost and make operations more eco-friendly and sustainable.
The major part of the conference is designed to have case-studies, techno-economic feasibilities, practical issues, impediments and their possible solutions to facilitate mining and power sector to harness the advantages of use of fly ash.
Senior bureaucrats, policy makers, technocrats, field engineers, planners, scientists, academicians, regulators and environmentalists would deliberate the issues thread ware.
The country’s dependence on coal for power generation has not changed. Thus, fly ash management is a cause of concern for the future
The projections made by Planning Commission as well as Ministry of Power upto 2031-32 indicate that 2/3rd of power generation in the country would continue to depend on coal. The annual generation of fly ash is expected to be around 175 million tonne by end of XIth Five Year Plan Period, 225 million tonne by end of XIIth Five Year Plan Period and around 500 million tonne by 2031-32.
The fast growing power sector with target to add 1, 00,000 MW every Five Year Plan, would have higher and higher demand for coal, resulting in generation of large volumes of fly ash. It was 40 million tonne per year during 1994 when the Fly Ash Mission was commissioned.
Now it has reached to the level of 160 million tonne per year. The corresponding utilization figures are 1 million tonne per year during 1994 (3% of generation) and 80 million tonne per year during 2009-10 (50% of generation). The fly ash generation is expected to increase to 190 million tonne per year (2011-12), 300 million tonne per year (2016-17) and 700 million tonne per year (2031-32).
More than 175 million tones of fly ash are expected to be generated in the country by the year 2012. This would require about 40,000 hectares of land for the construction of ash ponds. Such a huge quantity does pose challenging problem, in the form of land uses, health hazards and environmental dangers. Both in disposal, as well as in the utilization, utmost care has to be taken, to safeguard the interest of human life, wild life and environment.
Availability of land is big challenge for the power producer. All ready India is facing lot of problem in the land acquisition for setting up industry.
Fly ash is available in large quantities in the country as a waste product. This fly ash stored in dry condition in the ash ponds can become air born & thus polluting the air and resulting in health hazard.
By nature fly ash is eco-friendly. It can be safely used in agriculture, mines, road/ embankment, as building material, etc. It is not a garbage or waste material but it is a resource that can be used in creating wealth, prosperity, innovative product and opportunity of employment.
Fly ash from coal fired Thermal power plants is an excellent material for the manufacture of other construction materials like fly ash bricks, mosaic tiles and hollow blocks. The manufacture of conventional clay bricks requires the consumption of large amounts of clay. This depletes top soil and leads to degradation of land.
The World Bank has cautioned India that by 2015 disposal of coal ash would require 1000 square km. or one meter square of land per person.
Concern & Challenges
Fly ash is a by-product of coal combustion in thermal power plants, and India produces over 100 million tonnes of fly ash annually, the disposal of which being a growing problem in the country.
Nearly 75% of India’s total power generation capacity is thermal, of which coal-based power generation is nearly 90%, and diesel, wind, gas and steam adding to about 10%. High ash content in the range of 30 to 50% in Indian coals is the major cause of large voluminous quantities of coal ash. India’s dependence on coal as a major source of energy had been of prime importance in the past and shall continue in this millennium, and therefore fly ash management would remain an important area of national concern. At present nearly 170 million tonnes of fly ash is being generated annually in India and more than 70000 acres of land is presently occupied by ash ponds.
On one hand, there is a challenge to use the balance un-utilized quantity of fly ash, which if left unattended would pollute the environment, on the other hand mining industry has a number of operational challenges to enhance the production to meet the increasing demand of power and steel sector.
180 billion tonnes of clay brick production per year consumes 540 million tonnes of clay, makes 65000 acres of land barren, and consumes 30 million tonnes of coal equivalent, generates26 million tonnes of Carbon Dioxide. A 10% switchover to fly ash bricks will use 30 million tonnes of fly ash every year, save environment and coal and yield a benefit of 300 crores by way of reduction in brick cost production.
All out efforts are needed to utilize this fly ash not only from environmental considerations, but also to avoid land usage for fly ash dumping.
Why in Chhattisgarh
It’s true that Chhattisgarh would be come a power hub with the production, but on the flipside if the fly Ash caused by these projects is not properly managed, the state would certainly become a Fly Ash hub as well. Consequently the entire atmosphere would be filled with black smoke, which would lead to the occurrence numerous fatal disease & water scarcity.
With the focus on setting up a large number of Thermal Power Plant in the state, the need to manage fly ash becomes a major issue of environment concern with serious environmental consequence for the future. Fly ash need to manage not only to reduce environmental pollution, but also to recycle and reuse to recover some valuable resources.
With the prime objective of solving the environmental problem of safe and bulk disposal of fly ash and to use it in bulk for constructive purposes like wasteland development, agriculture, brick and cement making, roads and embankment development, the government of Chhattisgarh always encourages to all concerns, involved in the activities.
Chhattisgarh is the first state that provides uninterrupted quality and cheap power on 24×7 basis, for both urban and rural.
In the next 5 years, likely capacity addition of 30,000 mw power plant with an investment of Rs 1, 50,000 crores. In the next 3 years, Korba will be generating 10,000 mw of power and would become the energy capital of India. In the next 3 years, the electricity companies of state will invest Rs 17,000 crores in generation, transmission and distribution infrastructure. Per capita energy consumption increased from 354 units to 1500 unites. Farmers are being provided with 6000 units free electricity per annum, 2.8 lakh pumps energized.
Besides this the production of waste namely fly ash would only further deteriorate the scenario. Suppose there is 30% of ash in coal, then total amount of ash would be produced at the rate of 5000 tonnes per hour. If assumed yearly production is of 8000 hours, the total 4 crore tonnes of ash and about 13 crore tonnes of carbon dioxide would be emitted every year.
CREDA, Chhattisgarh asserted that the related ministry has provided acceptance for 20000 MW electricity production projects in the Chhattisgarh. As now these projects are being implemented, a terrifying picture is emerging on the scene.
INDIACSR hopes this conference will promote fly ash utilizations in the state of Chhattisgarh.
