In Japan there are almost no garbage bins. You can find some that are for recyclable goods, like PET-bottles. Other ones are difficult to find, though you can often find some when you find a convenience store. This is one of the few things that are somewhat inconvenient in Japan. According to my older friends in Japan, Japan also used to have garbage bins everywhere, like most normal countries in Europe. Then someone put sarin gas in garbage bins in Tokyo and killed lots of people. After that, they removed all the garbage bins. And to be fair, no one has gassed people to death since then, so in that sense it worked.
In Poznan, there are of course garbage bins everywhere, so you do not have to carry all your garbage all the way home with you.
