Companies ready to buy stubble to prevent farmers from burning it
NEW DELHI: Pollution-plagued Delhi can finally heave a sigh of relief, now that the National Thermal Power Corporation (NTPC)andafewbiomasspower unitshaveexpressedtheirintent to purchase crop residue from farmers in surrounding states.
Agricultural stubble running intomillionsoftonnesisburntby farmers in northern India every October, triggering heavy pollution in Delhi-NCR before the onset of winter.
As many as 35 million tonnes areburntinPunjabandHaryana alonetomakeroomforthewinter crop. Lack of alternatives to immediately dispose of the stubble was the primary reason for farmers setting crop residueafire.TheNationalGreen Tribunal had banned the practice.
This move of the NTPC and a few other biomass power plants across Haryana, Rajasthan and Punjab may bring some relief to the city of 12 million.
“Co-firingatpowerstationsby using biomass with coal is one of the initiatives being pursued by the NTPC,” a senior official said.
While the stubble will help generatepower,theby-productof the plant can be used as fertiliser because of its phosphorus-rich quality.
The issue was discussed at a meetingheldbytheEnvironment Pollution (Prevention and Control) Authority [EPCA] – the Supreme Court-mandated body for curbing pollution in the NCR – earlier this week.
EPCA chairperson Bhure Lal said a few other companies also expressed their willingness to “harvest” agricultural stubble fromthefields, andpaythefarmersaroundRs1to2perquintalfor thesame. “Wearetryingtoorganise a meeting between Punjab and Haryana officials, NTPC authorities and representatives of other companies willing to cut andbuy crop residue from fields. It is likely to be held in Chandigarh,” said an EPCA member.
Burning a tonne of straw releases around 3 kg of particulate matter, 60 kg of carbon monoxide, 1,460 kg of carbon dioxide, 199 kg of ash and two kg of sulphur dioxide, causing severe air pollution and triggering a number of ailments.
The practice also depletes the soil’s nutrient levels.
