These crackers are 15-20 % cheaper than conventional ones and NEERI team involved in the project has 80 % women scientists E-crackers also being developed with products like E-Ladi, E-Anar, E-cracker show For the first time an Emission Testing Facility established in India for sound and emission testing of crackers
“CSIR scientists have developed Less Polluting Firecrackers which are not only environment-friendly but 15-20 % cheaper than the conventional ones”, said Dr. Harsh Vardhan, Union Minister for Science & Technology, Earth Sciences, Environment, Forest & Climate Change at a press conference here, today.
These crackers have been named as safe water releaser (SWAS), safe minimal aluminum (SAFAL) and safe thermite cracker (STAR).
These crackers have the unique property of releasing water vapor and /or air as a dust suppressant and diluent for gaseous emissions and matching performance in sound with conventional crackers.
SWAS crackers eliminate usage of (KNO3) Potassium nitrate and Sulphur with a consequent reduction in particulate matter (30-35%) SO2 and NOx. It has matching sound intensity with commercial crackers in the range of 105-110 dBA. SWAS has been tested for shelf life up to 3 weeks with consistent performance.
STAR eliminates usage of KNO3 and S with a consequent reduction in particulate matter (35-40%), SO2 and NOx. It has matching sound intensity with commercial crackers in the range of 105-110 dBA.
SAFAL has minimal usage of aluminum (only in flash powder for initiation) with a consequent significant reduction in particulate matter (35-40 %) compared to commercial crackers. It has matching sound intensity with commercial crackers in the range of 110-115 dBA.
Indian Fireworks industry is over 6000-crore worth of annual turnover and provides employment opportunities to over 5 lakh families directly or indirectly. This endeavor of CSIR aims at addressing the pollution concerns at the same time protecting the livelihoods of those involved in this trade. These Firecrackers are not only environment-friendly but 15-20 % cheaper than the conventional ones.
