Beijing’s subway lets you pay with PET-bottles

Beijing’s subway line 10 has introduced reverse vending machines which allow travellers to offset their transit costs by recycling.

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

Insert a plastic bottle, wait twenty seconds until the bottle is crushed to a third of its original size. Donors will then receive between five fen to one jiao on their commuter passes for each empty bottle
