Plastic Bottles problem
In most of European countries when one buys cold drink/drinking water, he/she must pay a deposit for plastic bottle, which one gets back after submitting bottle at vending machines placed at most of super markets.
In India also we government can and should make cold-drink manufacturing companies to establish a mechanism to collect bottles back. Companies can collect say Rs 5, as deposit per bottle and give it back once people put bottles back into vending machines. This way there will not be any bottles lying in opens as they have good value.
I guess this can give boost to Swatch Bharat and provide people a strong reason to believe that government is serious about Swatch Bharat more
