There are already some pretty impressive recycling robots, especially in the field of sorting out mixed recyclables (scanning the incoming stream and shooting stuff that matches certain parameters into a separate area). It's pretty cool, you should check it out. I don't know how economical they are but they still require human backup because of the sheer variety of (incorrect) crap put in recycling bins.
You need to be careful putting taxes on these things because of their regressive nature. Who winds up feeling the pinch when you add a $.05/can tax on soda cans? Does that person really have time to make extra trips to the supermarket to redeem a few dollars worth of cans?
Also while landfills are among the ultimate NIMBY things, we're not running out of space on this earth in any real sense.
Some things are just not worth doing economically. Maybe we should go back to the old ways and have consumers sort into only a few categories that are easier to manage - e.g. "paper" and "bottles and cans", and not bother with the rest.
