Look up the Pfand system in Germany. Most domestic beer comes in one of two brown glass bottle shapes with brewery-specific labels. Any brown glass bottle of that shape can be turned into a few cents (I think it was 12.5) at essentially any grocery store's machine. Bottles are washed/reused up to 40-50 times before they even need to be melted down and recycled. Because of the reward there are people who roam around and pick up bottles every day, so a glass bottle in a park has a lifetime of about 1/2 day max. A few other drinks come in those bottles, e.g. Spezi. But coke? Nope. Plastic and aluminum. Imported beer? Nope. The system in Germany isn't perfect, but it's pretty damn good.
