The US is largely single stream recycling which means human sorting. Glass breaks, so it's a laceration risk for the single stream sorter AND broken glass can damage the machinery. The US is a large country with many states bigger than EU countries. Even within a state, the cost to move the glass to an appropriate facility makes it unprofitable. Even with split stream, the broken glass is still a hazard and glass remains heavy to transport. There's just no current way to recoup the cost. I don't like it, but those are the facts.

Edit to add: I'm not trying to be a prick, but before randomly arguing a point, maybe do some research. Any search engine should provide answers.
