Here's a decent setup in Central Park. A rollout bin has been modified for recycling bottles and cans, with a trash can strategically located right next to it to reduce chances of contamination.
In the subways of New York City, they claim that recyclables will be separated out from the trash. Certainly simplifies things on the collection end. There have been a lot of advances in separation technology.
The last photo was taken at the skating rink at Penns Landing in Philadelphia. Great place to go, by the way, but their trash/recycling duo is doomed to failure. True, they are paired, and the recycling container looks different, but the wide mouth insures that the uncaring masses will contaminated it with trash.
