Your first night in the new flat, you finish unpacking and face a wall of bins in four colours and a neighbour watching to see which one you open. You drop a pizza box in the wrong one. By morning it has been moved, pointedly, to the correct bin. You have just had your first lesson in Mülltrennung, the German art of sorting rubbish, where getting it wrong is a minor social crime.
Germany recycles more than almost any country, and it does it by pushing the sorting onto you, the household, at the point of disposal. The system looks fussy until it clicks, and then it is genuinely simple: four bins, a few rules, and one thing that never goes in any of them.
The four bins
Most German households deal with four colour-coded streams. The exact colours vary slightly by region and waste company, but the logic is consistent.
| Bin | Name | Takes |
|---|---|---|
| Yellow | Gelber Sack / Gelbe Tonne | Packaging: plastic, metal, composite cartons |
| Blue | Papiertonne | Paper, cardboard, newspaper |
| Brown | Biotonne | Food scraps, garden waste, organic |
| Black/grey | Restmüll | Everything left over |
Glass is the exception: it does not go in any of these. It goes to separate public glass banks, covered below. And deposit bottles go back to the shop, never in a bin.
The yellow bin: packaging, not all plastic
The yellow bin (Gelber Sack as a bag, Gelbe Tonne as a bin) is the one people get wrong most. It is for packaging, marked with the Grüner Punkt or similar, not for all plastic.
In go: plastic wrappers and film, yoghurt pots, plastic bottles without deposit, metal cans, aluminium foil and trays, and composite cartons like Tetra Pak juice and milk boxes. Out stays: a broken plastic toy, a plastic bucket, or a cracked storage box, because those are not packaging. Those go to Restmüll or, for bulky items, the Wertstoffhof (recycling centre).
The mental test: was this the wrapping something came in? If yes, yellow. If it is the thing itself, usually not.
Paper, Bio, and Restmüll
The other three are more intuitive.
Blue (Papiertonne) takes paper, cardboard, newspapers, magazines, and packaging cardboard. Flatten boxes so the bin holds more. Keep out anything greasy or waxed, a grease-soaked pizza box belongs in Restmüll or Bio depending on local rules, not paper.
Brown (Biotonne) takes organic waste: food scraps, peelings, coffee grounds, eggshells, and garden trimmings. Some areas allow compostable bags, many do not, so check, because the wrong bag contaminates the batch. Not every building has a Biotonne; where it is missing, organics go to Restmüll.
Black or grey (Restmüll) is the catch-all for what fits nowhere else: hygiene products, vacuum dust, broken ceramics, heavily soiled items, cigarette ends. The cleaner you sort the other three, the less Restmüll you produce, which in some municipalities lowers the building's waste cost.
Glass: to the bank, by colour
Glass jars and non-deposit bottles go to public glass banks (Glascontainer), the large containers on street corners, sorted by colour:
- Weiß (white/clear glass)
- Grün (green glass)
- Braun (brown glass)
Blue and other coloured glass goes in the green bank by convention. Remove lids (metal lids to the yellow bin). And note the noise rule: glass banks have time restrictions, and using them during Sunday or evening quiet hours is discouraged because shattering glass is loud. Deposit (Pfand) bottles never go here, they go back to the shop for your money.
The social side and the rules
Mülltrennung is enforced less by fines than by neighbours and the building. Correct separation is a real social norm, and a visibly mis-sorted bin invites correction, sometimes a note, sometimes the offending item physically relocated.
There are harder consequences too. A bin contaminated with the wrong material can be refused collection by the waste company, leaving it full until the next cycle, and persistent contamination can mean extra charges passed to the whole building. Bin rules and any rota (who wheels the bins out on collection day) often sit in the Hausordnung, the house rules you agreed to with your tenancy.
Bulky waste (Sperrmüll), electronics, batteries, and hazardous items have their own routes, usually the Wertstoffhof or a scheduled Sperrmüll pickup, never the household bins.
What to do this week
- Learn your building's specific bin colours and where each one lives, since regional waste companies vary the exact scheme.
- Run the packaging test on plastic, was it the wrapping (yellow) or the thing itself (Restmüll), to fix the most common sorting error.
- Find your nearest glass bank and recycling centre (Wertstoffhof) for glass and bulky items that no household bin accepts.
