Let's take a look at a trash can together, why don't we?
So, meet Mr. Trash Can of the K in Lautern Mall. He has many cousins in the mall, too, and they're hungry for what you want to toss.
Now that we've made his introduction, let's take a peek at his three hungry mouths, why don't we?
Mouth #1, labeled Papier, is on the left. Can you guess what this is? Take out the "i" and you have "paper." Not too bad, eh? So, you'd throw paper in here, such as receipts, those flyers people hand you as you unsuccessfully try to dodge them during shopping, etc.
Mouth #2, in the center, is for Kunstoff, which is plastic. It also might be labeled as Verpackung, which is packaging. This is where you can put empty containers.
Mouth #3, on the right, is Restmüll, or garbage. It also might be labeled as Abfälle. In this Mr. Trash Can's case, you'd put whatever else doesn't belong in his other two mouths here.
A mouth not pictured here is one for Glas (glass).
There you have it! Before you throw something in, make sure that you pick the right mouth. You don't want to anger the rubbish gods nor those of the Germans who are just ready to get their Schimpf on.
