New Kiln technology in Punjab: 70% emissions cut
Following orders from NGT (National Green Tribunal) and CPCB (Central Pollution Control Board) the Punjab Government had ordered the closure of traditional kilns in March 2019. This was mainly to control the toxicity of the NCR (National Capital Region). The stubble burning, industrial and kiln smoke from Punjab, brought by the retreating monsoon during this time, slogged Delhi making lives difficult. Schools are closed and the routine normal life is highly disrupted.
Scenario in Punjab
The new Kiln Technology cuts the emissions by 70-80%. It also saves fuel for the users. The districts of Punjab like Barnala and Sangpur have seen 100% conversion. Around 800-900 kilns in Punjab are yet to convert to the new technology according to Department of Science and Technology (DST).
The kiln industry in Punjab employs 5 lakh workers. It contributes to 8% of brick production in the country producing 15-20 billion bricks.
The new technology is being implemented by the DST. The DST provides technical assistance to the traditional kilns to get converted. This is being done through the Punjab State Council for Science and Technology
About the Technology
In the new kiln technology, the bricks are arranged in zig-zag pattern. This allows hot air to cover long path unlike traditional kilns. The heat transfer is improved due to zig-zag pattern. This makes the operation more efficient and reduces coal consumption by 20%. It also uses fans to regulate air.
