What happens to the millions of PET water bottles after you use them? At the Sabarmati Riverpark in Ahmedabad, Gujarat, we have created a solution. Our reverse vending machine helps recycle the plastic in a more effective manner! More than 2500 plastic bottles are dropped into this every month, the crushed plastic is then sent to recyclers. Visitors to the park are encouraged to drop their bottles here, in return for a discount coupon for the park facilities.
