Shanghai Airport's Brilliantly Simple Lighter Recycling System

China has a booming air travel industry and 350 million smokers. That means a lot of lighters get confiscated at security checkpoints.

At Pudong International Airport in Shanghai, instead of trashing the lighters confiscated from departing passengers, they're provided for free to arriving passengers. It's a brilliantly simple way of preventing a lot of plastic from ending up in the trash (and saving people a little cash).

Here in the states some airports sell confiscated items on Ebay or donate them to the homeless, but I've never seen this much simpler tactic employed. Would it work with shampoo, too, or are there hygiene issues?
