METRO COULD SAVE ON TRASH CANS WITH THIS IDEA, TOO

Beijing has installed recycling bins that give public transit credits for plastic "PET"bottles.

"With the machines, the firm hopes to collect directly from the public and generate extra revenue from government subsidies and sales of advertising shown on the machine's screens. Incom says it plans to approach Coca-Cola and other beverage retailers.
Similar devices have been used in several countries, including the US, Japan and Brazil, but they have benefited from civic mindedness, convenience and widespread ignorance about the true value of PET."

This is such a brilliant idea, I don't know why every city doesn't do this!

Step up, Metro!
