In news: To resolve the crisis of air pollution, the Government of India launched green firecrackers developed by Council of Scientific and Industrial Research (CSIR). 

More about Green crackers: 

  • The emissions testing facilities for the new fire crackers have been set up at CSIR-NEERI. Further, a Raw Materials Compositional Analysis (RACE) facility has been launched in Sivakasi to facilitate manufacturers for testing their chemicals.  
  • The Petroleum and Explosives Safety Organization (PESO), under the Union commerce ministry, was told to test the efficacy of the final product before it received the SC’s approval.
  • Barium, used as an oxidizer and to emit green light, is a crucial component of crackers. Due to its low prices and ready availability, it is used across a range of products, including ladi, anaar, and chakkars. A ban on barium indirectly meant a ban on nearly three-fourths of the crackers produced.
  • these fireworks, based on new formulations developed by CSIR, have been manufactured and are available in the Indian market for consumers and sellers.
  • a green logo as well as a Quick Response (QR) coding system has been developed for differentiation of green crackers from conventional crackers. 
  • 'Green' crackers have a small shell size compared to traditional crackers. They are produced using less harmful raw materials and have additives which reduce emissions by suppressing dust.
  • Green crackers don't contain banned chemicals such as lithium, arsenic, barium and lead. They are called Safe Water Releaser (SWAS), Safe Thermite Cracker (STAR) and Safe Minimal Aluminium (SAFAL) crackers.
  • Green crackers release water vapour and don't allow the dust particles to rise. They are designed to have 30% less particulate matter pollution.
