Green crackers are those crackers which do not contain harmful chemicals that would cause air pollution. They are environmentally friendly. So, we can say that green crackers are less harmful as compared to conventional firecrackers and less pollution emission will result in reduced air pollution. That is why it is decided to develop eco-friendly firecrackers and fireworks.
In green crackers the commonly used polluting chemicals like aluminium, barium, potassium nitrate and carbon have either been removed or sharply reduced to slow down the emissions by 15 to 30%.
Do you know that the idea of generating green firecrackers is of CSIR labs and is proposed by the Union Science and Technology Minister Dr. Harsh Vardhan?
In the first phase of producing green crackers focus will be on reducing pollutants and then further strategies will cover to remove pollutants from the compositions.
The team have came up with 3-4 formulations and looked at 30-40% of active materials which reduce particulate matter. Also, CSIR-CECRI has developed eco-friendly flower pots that can reduce particulate matter by 40%.
Even, CSIR-NEERI is testing the efficacy of crackers known as Bijli crackers. They have eliminated the use of ash as desiccants. They have developed potential sound-emitting functional prototypes that do not emit sulphur dioxide. All these are in testing stage.
The crackers have been named as Safe Water Releaser (SWAS), Safe Thermite Cracker (STAR) and Safe Minimal Aluminium (SAFAL). The particulate matter will be reduced by 30-35 per cent in SWAS and 35 to 40 per cent in SAFAL and STAR
According to the researchers, these crackers have the unique property of releasing water vapour, air as a dust suppressant and diluents for gaseous emissions that match with the performance in sound with traditional conventional crackers. All, these crackers are now in a testing stage at the Petroleum and Explosives Safety Organisation.
Green crackers may not be implemented this Diwali but yes in future government is planning to implement them.
So, now we understood that green crackers are those which reduce emission and decibel levels.
Let us study the chemistry of fireworks
Basically, fireworks chemistry is based on theory of combustion. It consists of 6 vital ingredients.
1. Fuel: Charcoal basically known as black powder is the most common fuel used in fireworks. Therefore, all fuels will contain an organic element like charcoal or thermite.

Hey mate,
While permitting the use of firecrackers for celebration purposes, the Supreme Court on ruled out complete ban and said the use of green crackers are allowed and no dangerous, high polluting crackers can be burst. The apex court ordered that only crackers with reduced emission and green crackers can be manufactured and sold in the retail market.
As the name suggests, green crackers are said to be less harmful as compared to the conventional firecrackers. Green crackers do not contain harmful chemicals. It means that less pollution emission resulting in reduced air pollution. Quoting Dr Rakesh Kumar, Director, (CSIR-NEERI), a report by The Indian Express said that in the green crackers, the materials which are less harmful and less dangerous to the environment are used.
hope this helps you out!
