Order of the Supreme Court of India in the matter of Arjun Gopal & Others Vs Union of India & Others dated 11/04/2019 regarding manufacture of fireworks with new formulation. The fireworks manufacturers had requested permission for manufacture of fireworks with Barium substitute i.e. Barium Nitrate. This is said to reduce the pollution to the extent of about 25 to 30 per cent. SC declines the request saying the Petroleum and Explosive Safety organization (PESO) is looking into the matter for the best formulation that may be permissible for manufacture of firecrackers.
