The menace associated with fly ash will become a thing of past if it is utilized in a more meaningful way.  Assess the alternate uses of fly ash and the government’s measures in this regard. Fly Ash is a fine powder, which is the by-product of burning coal in thermal power plants.  It is a proven resource material for many applications of construction industries Uses: It is useful in
  1. manufacturing of portland cement, bricks/blocks/tiles manufacturing,
  2. road embankment construction and low lying area development, etc.
  3. agriculture as an agent for acidic soils, as soil conditioner as it improves the physio-chemical properties of the soil.
Advantages of Fly Ash Utilization: It has the potential to reduce
  1. greenhouse gas emissions by decreased mining activities.
  2. land degradation by decreased clay extraction for brick making.
  3. bio-accumulation by decreased usage of fertilizers in agriculture.
Government steps to use Fly Ash:
  1. In 2009, MoEF provided guidelines on ash utilization advocating its usage within 100 km radius of thermal power plants.
  2. NTPC is in the process of effectively using fly ash in various projects. (Manufacture of pre stressed railway concrete sleepers).
  3. Maharashtra became the first state in the country to adopt the Fly Ash Utilization Policy
  4. It has decided to come up with an export policy for fly ash in the light of demand from places like Singapore and Dubai.
  5. GST rates on fly ash and its products have been reduced to 5%
  6. ASHTRACK app has been launched to monitor fly ash generation and utilization data of Thermal Power Plants
  7. Ash-park has been developed and awareness programme for utilisation of fly ash and its products have been conducted.
Road Ahead: India has the potential to produce 600 million tonnes by 2030 hence its use should be promoted in all possible ways.
