This is a great idea. I guess the manufacturers would print the tags somewhere on all items that are produced - like cigarette warning labels? Still, I imagine there would have to be many human hand sorters of the trash like shown in the video. San Francisco is working towards it's goal of 100% recycling of it's trash and I believe is currently about 85%. Smart dust tags potentially could immediately reduce the costs, time, and labor involved in recycling.
