- 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.
