A bench headed by NGT Chairperson Justice Swatanter Kumar directed all state governments to prohibit the "manufacture, sale, storage, purchase and use" of synthetic manja or nylon threads and all other synthetic threads used for flying kites.
The green panel clarified that the ban order would apply on nylon, Chinese and cotton manja coated with glass.
"There shall be a total ban on the manja or thread for kite flying which is made of nylon or any other synthetic material and or is coated with synthetic substance and is non-biodegradable...
"All chief secretaries of states and Union Territories are directed to enforce prohibition on manufacture and use of synthetic manja/nylon thread for flying kites throughout the country," the bench said.
"Due to 'manja' being coated with glass, metals and other sharp material, these strings act as good conductors of electricity, increasing the probability of detached manja strings stuck in power lines, electrocuting kite flyers and passers-by coming into contact with these strings," the petition had said.
PETA had averred that minor children were engaged by the cottage industry for the manufacture of 'manja' which caused respiratory problems as they inhaled harmful substances which were extremely detrimental to their health.
