Ever wonder what happens to that aluminum beer can, plastic yogurt cup, or cardboard pizza box after you toss it in the recycling bin?
Well, so did the good people at the Massachusetts Institute of Technology, who in 2009 embarked on an ambitious effort to tag 3,000 pieces of trash with GPS-type sensors and track them through the national waste stream. They announced the project shortly after the publication of a three-part series in Mother Jones in which I followed my garbage and recycling through San Francisco’s legendary recycling and composting system.
I’d also wanted to attach GPS tags to my trash, but unlike the nerds at MIT, didn’t have $300,000 to drop on sensors. The MIT team synthesized their results into this fascinating video, which has been out for a while, sure. But it’s still totally worth watching.
