Use of paddy waste in thermal power plants (up to 10%) is an important external straw management strategy.
Paddy waste is used in waste-to-energy plants, brick kilns and as final products such as pellets, bio-fuels (bio-ethanol) and packaging materials.
Air pollution in the national capital rises to alarming levels in October and November. The main reason for this is that stubble burning is done by the farmers of Punjab, Haryana and Uttar Pradesh.
Farmers eliminate crop waste by setting fire to clear their fields for sowing wheat and potatoes.
In Punjab, 20 million tonnes, Haryana and Uttar Pradesh’s eight NCR districts produce 7.5 lakh tonnes and 7.5 lakh tonnes of stubble every year.
NTPC uses paddy waste in its thermal power plants. The company had earlier told the commission that it is technically feasible to use five to 10 per cent of paddy waste based pellets as fuel with coal in power plants (co-firing).
It is said that efforts are being made to use 5 million tonnes of biomass pellets in 17 power plants.
The CAQM has asked the states to formulate a policy framework to ensure assured and sustainable supply of raw materials using paddy crop waste to power plants.
States have been asked to use paddy waste pellets in their own thermal power plants.
