Cultural Background
Mülltrennung is often called a 'national sport'. It is a point of pride and a way for citizens to feel they are contributing to the 'Energiewende' (energy transition). Similar to Germany, but colors can vary. For example, the 'Mistkübel' (trash can) is a common regional word for bin. Extremely strict. In many cantons, you must use official, expensive trash bags (Gebührensäcke) for non-recyclable waste to encourage people to 'den Müll trennen'. While recycling exists, it is often 'single-stream' (everything in one bin), which confuses Germans who are used to 'multi-stream' separation at the source.

What It Means
Den Müll trennen is more than a chore. It is a fundamental part of German life. You sort your waste into different containers. Paper goes in the blue bin. Plastic goes in the yellow bag. Food scraps go in the brown bin. Everything else goes in the black bin. It sounds complicated at first. However, it becomes second nature very quickly.
How To Use It
You use this phrase just like any other verb-object pair. The verb trennen changes based on the person. For example, you say Ich trenne den Müll. If you are asking a roommate, say Trennst du den Müll?. It usually appears in the present tense for habits. You can also use it with modal verbs. Wir müssen den Müll trennen is a common household rule.
When To Use It
Use it when discussing household chores. It is a common topic with roommates or landlords. You will hear it at the office too. Colleagues might remind you where the paper bin is. It is also a great small-talk topic. Germans love discussing the efficiency of recycling. Use it when you move into a new apartment. Ask your neighbors: Wie trennt man hier den Müll?.
When NOT To Use It
Do not use this for people. If a couple breaks up, you do not use Müll trennen. That would be very insulting! Also, do not use it for abstract ideas. You don't trennen your thoughts like trash. It is strictly for physical waste management. If you are sorting laundry, use Wäsche sortieren instead. Keep it focused on the bins.
Cultural Background
Germany is world-famous for its recycling system. It started in the early 1990s. It is a matter of national pride and duty. If you throw plastic in the paper bin, neighbors might notice. They might even leave a polite (or grumpy) note. There are even 'trash detectives' in some cities. It is a way of showing you care for the environment. It is a social contract everyone signs.
Common Variations
You might hear Müllsortierung for the general concept. People also say Recycling betreiben, but that sounds very formal. Wertstoffe trennen is another technical version. Most people just stick to the simple den Müll trennen. If you want to be specific, say Altglas wegbringen. That means taking glass bottles to the public containers. Don't forget the quiet hours when doing that!
Usage Notes
The phrase is neutral and used across all levels of society. The most important thing is to remember that 'Müll' is masculine (den Müll) and the verb 'trennen' is regular.
The Pizza Box Rule
A dirty pizza box with grease belongs in the Restmüll (grey), not the paper bin (blue)!
Lids off!
When you separate trash, take the aluminum lid off the plastic yogurt pot. They go in the same bin but need to be separate for the machines to sort them.
Avoid the 'Müllpolizei'
If you live in an apartment block, follow the rules strictly to avoid complaints from neighbors.
