FLY ASH




CAN PROPER UTILIZATION OF FLY ASH ADD TO OUR GDP?

India’s power consumption is on the rise so as its production. As thermal power stations are increasingly consuming coal to produce energy, the fly ash generated in the process needs better and innovative ways of utilization or disposal.

Burning of coal to meet the energy needs of the country is piling up the fly ash which has reached about 100 million tonnes per year. 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. Though there has been a steady progress in fly ash utilization since the last decade, there is still a long way to go to reach the target of 100 per cent fly ash utilization. It is reported that the fly ash use in agricultural can increase the production of grains by 15 per cent, green vegetables by 35 percent and root vegetables by an astounding 50 per cent. Toxicity tests have proved that fly ash not only reduces toxic elements in the soil but nourishes it with iron and calcium. Optimum utilization of fly-ash with business prowess has the potential to change the discourse of many businesses. It can become a wealth generator by making use of it for producing ‘green building’ materials, roads, agriculture etc. Full utilization of the generating stock has the potential to provide employment to three hundred thousand people and can result in a business volume of over Rs.4000 Cr approximately.

So the question is how to embrace the opportunity and take a step towards cleaner environment by utilizing Fly Ash in our respective industries?

On the basis of studies carried out on fly ash utilization, it is sighted that use of fly ash in building construction possesses great gains. Either fly ash used in brick manufacturing or in concrete mixes, it gives very good results in almost every aspect including product strength, economical viability and environmental friendly. Previously Fly Ash was looked upon as an industrial waste and a pollutant. The perception has undergone considerable change over the past few years. Now Fly Ash has attained the status of a resource material. However, there is a greater need for awareness on implementation ideologies of Fly Ash utilization and disposal. The guidelines for all thermal power stations as regards disposal techniques/ strategies should ensure minimum adverse impact on the flora & fauna of a particular place. The attempt should be to consciously reduce environmental damage to ensure more effective management of fly ash which India needs. 

It's time to think GAINFUL UTILISATION TECHNOLOGIES AND TAKE A STEP TOWARDS CLEANER ENVIRONMENT & 100% UTILISATION OF FLY ASH
