You also could return older, non-deposit containers at the beginning. This spurred me and my friends to clean every roadside and field within reach of our bikes. For a month we made more money than we had known in our entire lives. Then it was over and a valuable lesson was learned.
There also are mandatory recycling quotas.
- There are no special regulations for multi-way bottles (glass and plastic alike). Most stores will accept only those they are incentivized to, i.e. the brands they sell (manufacturers are eager to get them back to be able to reuse them).
- As soon as a store sells a kind of one-way container (plastic bottles, aluminum cans), they have to accept, pay out the mandatory €0.25 deposit for, and properly dispose of each and every one-way container of that kind customers bring in (in household quantities). There is a clearing mechanism, since store's sales might not match their returns.
So, for example, if law allowed only for a small number of different container types (to turn them into a commodity) and then taxed production of those containers heavily, what exactly would happen?
Naively, one would expect companies to cut costs by buying second-hand containers rather than buying expensive new ones.
That would create a market for used containers. For an ordinary person it would be very much like deposit: Buy stuff with the price of container included, then sell the container to get back the money.
It would, obviously, provide a new way to cheat: Produce new containers and sell them as used ones, thus avoiding the tax. But that's just a tax avoidance trick and could be dealt with using the existing anti-tax-avoidance mechanisms.
It would be interesting to know what would be the unintended consequences of such a law.
It'd be a little safer if they could just pick through recycling bins, but that's illegal [1] so they are forced to pick through trash bins.

Going more frequently with smaller amounts would pay more but waste more time... and I estimated that it didn't make sense to do so unless you valued the cost of the trip at less than about $1.
For other and broken glass items there are glass containers pretty much everywhere, broken up by color (white glass, brown glass, green glass). Plastics delivered by consumers are separated but never recycled.
According to official figures about 51% of plastics are recycled, 38% is burned [1].
