Researchers track 3,000 pieces of Seattle trash

SEATTLE — Where does that coffee cup, disposable razor or unwanted television end up once it's tossed to the curb?

Using an electronic tracking device about the size of a matchbook, MIT researchers are tagging about 3,000 pieces of Seattle trash to get people thinking about what they throw away and where it ends up.

"Seeing where your trash goes allows you to change your behavior," said Assaf Biderman, associate director of MIT's SENSEable City lab and a project leader. "Will you refill a cup instead of throwing away a disposable one?"
