Hyderabad, August 13, 2012: While bottles of mineral water are increasingly becoming a major cause of pollution, not much is being done about it. A reason for this is that the entire focus of Plastic Waste (Management and Handling) Rules, 2011, is on polythene bags and their thickness and that the rules to ensure the responsibility of disposal is on the manufacturer. Nobody cares to know where tons of plastic bottles containing water or other beverages, thrown carelessly after consumption, are being dumped. Even the authorities are conveniently passing the buck saying it is not covered under the amended rules.
