Did you know: Travelers in Beijing subway “pay” with plastic bottles

Beijing’s subway authorities have introduced reverse vending machines which allow travelers tooffset their transit costs by recycling. Passengers insert a plastic bottle, wait twenty secondsuntil the bottle is crushed to a third of its original size. Donors then receive one jiao (1.6 cents) on their commuter passes for each empty bottle. The machines have been installed in two stations Jinsong and Shaoyaoju.

Recycling for a reward. The manufacturer of the machines, Incom says it’s easy.
