CSIR scientists have developed Less Polluting 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).
SWAS:
- It has 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 crackers eliminates usage of (KNO3) Potassium nitrate and Sulphur with 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 upto 3 weeks with consistent performance.
SAFAL:
- It has minimal usage of aluminium (only in flash powder for initiation) with 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.
STAR:
- It eliminates usage of KNO3 and S with 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.
