Green crackers are so named because they do not contain harmful chemicals that would cause air pollution.
- Components in firecrackers are replaced with others that are less dangerous and less harmful to the atmosphere.
The three broad categories of green crackers SWAS, SAFAL and STAR are developed by CSIR.
- SWAS (safe water releaser) has a small water pocket that is released in the form of vapour when the cracker is burst. This suppresses dust.
- STAR (safe thermite cracker) does not comprise potassium nitrate and sulphur, and emits reduced particulate matter at reduced sound intensity.
- SAFAL (safe minimal aluminium) which has minimum usage of aluminium, and used magnesium instead. This too emits less noise than traditional crackers.
