China Trash Sorting: 垃圾分类, the 4 Bins, and What to Say
How China’s Sorting Rules Got Serious
Shanghai went compulsory in 2019, and by 2026 most big cities followed with the same four-bin system plus 定时定点 fixed drop-off times. Individuals face fines of ¥50–200 for wrong sorting in the strictest cities. I’ve never seen a foreigner actually fined — enforcement leans on warnings — but the social pressure is real, and the bins now carry picture labels that make most sorting self-explanatory.
The Four Bins (Their Names Differ by City)
| Color | 中文 | Pinyin | What goes in |
|---|---|---|---|
| Blue | 可回收物 | kě huí shōu wù | Clean paper, plastic bottles, glass, metal, cartons |
| Red | 有害垃圾 | yǒu hài lā jī | Batteries, expired medicine, paint, thermometers |
| Brown/Green | 厨余垃圾 / 湿垃圾 | chú yú lā jī / shī lā jī | Food scraps, fruit peels, leftovers |
| Black/Grey | 其他垃圾 / 干垃圾 | qí tā lā jī / gān lā jī | Used tissues, ceramics, dirty plastic, wrappers |
City dialect alert: Shanghai says 湿垃圾 shī lā jī and 干垃圾 gān lā jī; most other cities say 厨余垃圾 chú yú lā jī and 其他垃圾 qí tā lā jī. Same system, different labels — learn the pair for the city you’re in. Fun fact: in Taiwan the same characters are read lè sè, which confuses mainland friends every time.
The Voice of the Bins: Ask the Auntie
My first morning in Shanghai, I stood between the bins holding a banana peel in one hand and its plastic bag in the other. A grandmother spent about ninety seconds fixing my life: peel to the brown bin, bag to the grey. Her kindness was the lesson — nobody expects you to know, and everybody’s happy to teach.
You: 阿姨，请问这个扔哪个垃圾桶？
ā yí, qǐng wèn zhè ge rēng nǎ ge lā jī tǒng? (Excuse me, which bin does this go in?)Neighbor: 这个扔湿垃圾，袋子扔干垃圾。
zhè ge rēng shī lā jī, dàizi rēng gān lā jī. (The peel goes in the wet bin, the bag in the dry bin.)
That one question — 这个扔哪个垃圾桶 — is the highest-value sentence in this article. Use it anywhere and you’ll never guess wrong twice.
Three Rules That Cover 90% of Situations
- Food waste goes in the food bin; the bag it came in does not. Shanghai even has a word for it: 除袋 chú dài, “remove the bag”.
- Anything wet or smelly contaminates recyclables. A greasy pizza box is 其他垃圾, not 可回收物 — this trips Westerners up more than anything else.
- Delivery parcels: the cardboard box and paper are recyclable; bubble wrap and plastic mailers are 其他垃圾. Most 驿站 pickup stations now have a box-recycling corner, so you often won’t even sort it yourself.
Daily-Life Vocab
| 中文 | Pinyin | Meaning |

| 垃圾桶 | lā jī tǒng | trash bin |

| 电池 | diàn chí | battery |
| 塑料袋 | sù liào dài | plastic bag (supermarkets charge a few mao for these in 2026) |
| 罚款 | fá kuǎn | fine |
| 定时定点 | dìng shí dìng diǎn | fixed times and spots (drop-off rules) |
Don’t Memorize the National Rules — They Don’t Exist
My contrarian advice: skip the sorting charts and learn two things — your city’s food-waste word and the question sentence. The bins carry pictures, and neighbors enforce the rest. Sorting is also a low-stress way to run into daily Chinese: grocery shopping fills your fridge, sorting empties your conscience, and both teach you more real vocabulary than a week of app drills.
