One great observation from Europe and one reason their deposit return rates are so high, especially Germany's, is that they have two deposit systems, one for single-use bottles. You want to attack the single-use plastic issue—the one-way water bottle, for example. The deposit is about 43¢, whereas on a refillable glass bottle it's only about 25¢ or 30¢ or something like that. It really does encourage a push to something like what Tom Szaky is promoting now with refillables and getting away from single use by creating a disincentive financially, or at least getting them back into the loop.
