Context:

The Delhi government scheduled to launch an anti-firecracker campaign on November 3.

  • Now, only ‘green’ firecrackers can be manufactured, sold and used in the national capital.

What are Green Crackers?

They are known as ‘green’ firecrackers because they have a chemical formulation that produces water molecules, which substantially reduces emission levels and absorbs dust.

  • They are the crackers with reduced emission and decibel level.

Benefits of Green Crackers:

  • They promise a reduction in particulate matters and harmful gases, like nitrous oxide and sulfur oxide, by 30- 35 per cent.
  • They will be 25-30 per cent cheaper to manufacture and manufacturers would not have to make any changes in their facilities.

What gives colour to the firecrackers?

Red: Strontium salts (Nitrates, carbonates and sulphates of strontium).

Orange: Calcium salts (Carbonates, chlorides and sulphates of calcium).

Yellow: Sodium salts (Nitrates and oxalates of sodium).

Green: Barium salts (Nitrates, carbonates, chlorides and chlorates of barium).

Blue: Copper salts (Carbonates and oxides of copper).
