'Green firecrackers' are the invention of National Environmental Engineering Research Institute (NEERI) which are similar to traditional firecrackers but their burning causes less pollution.
NEERI is a government institute, which comes under the Council of Scientific and Industrial Research (CSIR).

What are green crackers?
Green crackers are similar to normal crackers in appearance, burning and sound, but they cause less pollution.
Compared to normal firecrackers, these produce 40 to 50 percent less harmful gases when burnt.
Neeri's Chief Scientist Dr. Sadhna Rayalu says that they emit harmful gases, but it is not that they will not cause pollution at all.
Dr. Sadhana says that burning of normal firecrackers releases huge amounts of nitrogen and sulfur gas, but the aim of her research was to reduce their quantity.
The spices used in green crackers are different from normal crackers to a great extent. Neeri has created some such formulas which will produce less harmful gases.

How-To Green Crackers
Doctor Sadhna tells that her institute has prepared such formulas which after burning will produce water and dissolve in harmful gases.
There is a very special thing about these green firecrackers which differentiates them from normal firecrackers. Neeri has made four types of green crackers.
Water producing firecrackers: After burning, these firecrackers will produce water particles, in which sulfur and nitrogen particles will dissolve. NEERI has named it as safe water releaser. Water is considered a better way to reduce pollution.
Crackers producing less sulfur and nitrogen: NEERI has named these crackers as Star Cracker, i.e. Safe Thermite Cracker. Oxidizing agents are used in these, due to which sulfur and nitrogen are produced in small quantities after burning. Special chemicals are used for this.
Use of less aluminium: In this firecracker, 50 to 60 percent less aluminum is used as compared to normal firecrackers. The institute has named it Safe Minimal Aluminum i.e. SAFAL.
Aroma Crackers: Burning these crackers will not only produce less harmful gases but will also emit a better aroma.
