They call it Ricicli + Viaggi: Recycle + Travel. Three compactor machines, one on each of Rome’s three metro lines, gives a 5-cent credit for each bottle. Thirty bottles gets you a €1.50 ride!
Beautiful Rome is not renowned for the beauty of its recycling. But in the first 6 weeks of operation, these machines processed over 350,000 plastic bottles. Queues of people waited to swap them for €17,500 worth of free travel. Great idea + incentive = success!
