Metal cans

This is my first post under #cleanplanet. I learned about the action from @phortun three days ago ... I live in Central Europe, in the Czech Republic, in the capital of Prague. For three days I carry a plastic bag with me. When I go outside, I collect the cans from the ground. Typically, aluminum from beverages. This is my "catch" in three days. About 2 kg, about 100 cans. What about those cans now? There are special containers in Prague. You can also see the English "Metal cans only" inscription. Why do not people throw cans into containers? I do not know. I think that the situation with waste in the Czech Republic is quite good. Yet there is still room for improvement.
