The scientists of CSIR develops less polluting firecrackers named – SWAS, SAFAL & STAR

The scientists at CSIR have developed Less Polluting ‘Green’ Firecrackers which are not only environment friendly but 15-20 % cheaper than the conventional ones. These crackers have been named as Safe Water Releaser (SWAS), Safe Minimal Aluminium (SAFAL) and Safe Thermite Cracker (STAR). The commonly used pollution-causing chemicals – aluminium, barium, potassium nitrate and carbon – have either been removed or sharply reduced in the green crackers to reduce emissions by 15-30% . These eco-friendly firecrackers have the unique property of releasing water vapour and /or air as dust suppressant and diluent for gaseous emissions and matching performance in sound with conventional crackers. SWAS eliminates usage of (KNO3) Potassium nitrate and Sulphur, while STAR eliminates usage of KNO3 and S. On the other side, SAFAL has minimal usage of aluminium (only in flash powder for initiation) as compared to commercial crackers.The main point to be noted here is that these crackers match the same sound intensity with that of commercial crackers in the range of 105-110 decibel. The new crackers have been developed by scientists of two national labs of CSIR- Central Electrochemical Research Institute (CECRI) based in Karaikudi, Tamil Nadu and National Environmental Engineering Research Institute (NEERI) in Nagpur.
