Partly the reason the United States doesn't use reusable bottles anymore is because breweries became national instead of regional in the 1960s and 1970s. When your brewery is located in the same state as the beer is consumed it is easier to get the bottles back. If you are Coors and produce in one plant in Colorado it is more difficult and expensive to get your bottles back from Florida. Also the cost of shipping the heavier reusable bottles negates some of the cost savings as well.
