In Michigan we have had $0.10 deposit on beer bottles and pop(soda) bottles for a long time. It appears to extremely successful. You never see bottles littered anywhere, they are always picked up by someone in need. Gas station garbage can a frequently sorted through for returnables. School programs like band and sports teams will have bottle drives where they send the kids around through the neighborhood and collect bottles. It is a very successful fundraising method for them.

Growing up in Indiana, it was hard not to notice the contrast in side ditch cleanliness when crossing the state line. Part of it is cultural, too, as the ditches in WA are a lot cleaner than in my Indiana childhood, and WA doesn't have any bottle laws.
