In Denmark its 1-3kr, or 15-50¢, depending on the size and material of the container.

Plenty of cans are collected by homeless / lowest income people, but it's also just about enough that average people will collect them too.

If I have a huge bag after a party, I return them. When I normally only have 0-2 bottles in a typical week, I take them outside and put them on the little shelf on the bin for someone to collect without needing to rummage: https://www.magasinetkbh.dk/sites/default/files/public/style...

New food packaging can only use recycled material collected in this way. The general household recycling is considered too dirty.
