The Beijing Subway's Line 10 will soon have "reverse vending machines", which will pay customers for their empty plastic bottles.

After customers put their empty bottles into the machines, the devices identify and compact the bottles, and customers have their monetary reward scanned into their transportation cards.

The refrigerator-sized machines, about 40 in all, will be in most Line 10 subway stations.
