The Beijing Subway owners have begun to offer its passengers the ability to pay their bills with plastic bottles, thus helping to preserve the environment and helping the pocket of every traveler.

There are four machines that collect the bottles, are installed in the underground Shaoyaoju Jinsong and are on line 10.

On average, for every bottle recycle the passenger will receive between 0.5 and $ 0.15, and if we take accounts with around 15 bottles will have enough money to travel between 8 subway lines and 105 stations.

The recycled bottles are automatically collected and then sent to a processing plant plastics, for now this service is in testing phase, but it is expected that in the future can be implemented in each and every one of the Beijing subway stops, also plans to implement this service in the train stops.
