Skimming https://en.wikipedia.org/wiki/Container-deposit_legislation it seems return rates range from low 70s to high 90s percent for deposit-refund schemes around the world - not perfect everywhere - but plenty of countries have 95% rates which is as good as one can expect.

I'm sure the rates would be a bit lower if poverty was eliminated. Plenty of people collection bottles from trash cans and parks. The high rates imply that most people recycle bottles consumed in their own house though.
