In Finland almost every single can, and drinks bottle, has a corresponding price printed on it, ranging from €0.10 to €0.25. You can return them at almost any local store and receive cash.
There are hundreds of unemployed/retired/homeless people who scour parks, and the city centers, collecting these discarded containers and recycling them for the money.
The return rate is pretty high, even with the tiny amount of money per-item.
Note that the "homeless" people in Finland are mainly people who refuse to accept support from the social welfare, this is because they prefer to get drunk instead of spending it on food and rent. The social welfare eventually suggests a different system for such people: pay the rent for them and give a special card that can be used for anything except alcohol and cigarette. If the people keep refusing that other option, then they went homeless on their own accord and keep spending the welfare on alcohol and living on the streets. Such people are very rare in Finland in reality however, but they do exist.
There is also one woman [1] who for whatever reason chooses to live homeless with bunch of luggage. She doesn't drink at all, and keeps moving from town to town with all her luggage, by walking.
Here's also a discussion about the Romanian beggars you see in Helsinki streets. [2]
