Supreme Court has permitted only green crackers to be sold in Delhi-NCR region.:
Green crackers are fireworks developed by the government’s Council of Scientific and Industrial Research-National Environmental Engineering Research Institute (CSIR-NEERI).Green crackers were developed after the Supreme Court banned conventional firecrackers in 2017.They are made by reducing the size of the shells, eliminating ash, using fewer raw materials, and adding dust-suppressing additives.There are two main categories of green crackers: improved crackers that modify existing formulations to cut emissions; and new formulation crackers that replace polluting ingredients altogether.
Metals, which form part of particulate matter, are either minimized or eliminated to reduce toxicity.Green crackers exclude barium compounds, and have drastically-reduced aluminium and sulphur content.They rely on cleaner oxidisers and formulations that limit the release of harmful particulates.
