The genius' at MIT have devised a small tracking device that has been placed inside selective pieces of "trash" in order to track exactly where our trash goes once it's been thrown away. While we have a clear understanding of a supply chain, the experiment is being conducted to better understand a "removal chain".
The goal of the experiment is to help create more sustainable info structure within cities but also to try and instill behavioral change. The experiment is being done in Seattle, New York and London. Results we hope will be published soon, though the example shown on the MIT website shows a recycled paper coffee cup taking over 7 days to get to its final destination!
