The Supreme Court had on October 23 said in its guidelines that only firecrackers with reduced emission (improved crackers) and green crackers and Safe Water and Air Sprinklers (SWAS) would be made and sold.
The manufacture, sale, and use of joined crackers (series crackers or laris), the court said, were banned as they equally contribute to the air, noise and solid waste pollution. It added that those crackers, which have already been produced and do not fulfill the permissible conditions, would not be sold in Delhi and NCR.
