Few things confuse new arrivals in Korea more than throwing out the garbage. You cannot just toss everything into one bin — Korea runs a strict volume-based waste system called jongnyangje (종량제), where you pay for general trash by buying special bags, separate your food waste, and sort recyclables carefully. Get it wrong and you can face fines or find your bags left uncollected on the curb.
The good news is that once you learn the routine, it becomes automatic. This guide breaks down the official bags, food-waste rules, how to sort recyclables, what to do with bulky items, and the mistakes that lead to fines. Because the details differ by district, treat this as the framework and confirm the specifics with your local office.
The volume-based system in a nutshell
The core idea of jongnyangje is simple: the more general trash you throw away, the more you pay, because you must buy official volume-rate bags (종량제 봉투) to dispose of it. You cannot use ordinary plastic bags for general waste. The cost of the bag is effectively your garbage fee — so reducing waste and recycling properly saves you money.
Buying the right general-waste bags
You buy volume-rate bags at convenience stores and supermarkets in your district. When buying:
- Ask for the general-waste bag (종량제 봉투) and confirm it is for your district.
- Choose a size — they come in several liter sizes; pick what suits your household.
- Use these bags only for general, non-recyclable, non-food trash.
Tie them closed and put them out at your building's designated spot on the correct day.
Food waste is separate
Food waste (음식물 쓰레기) must never go in with general trash. It is collected separately, and depending on your building the method varies:
- Designated food-waste bags you buy and fill, then place at the collection point.
- A pay-as-you-go RFID bin in many apartment complexes — you tap a card or tag, the bin weighs your waste, and you are charged by weight.
- Food-waste stickers or containers in some buildings.
Drain liquids first, and remember that some items people assume are food waste are actually not — large bones, shells, eggshells, and certain hard or fibrous scraps may need to go in general trash. Rules on this vary, so check your district's guidance.
Sorting recyclables
Recyclables are collected separately from both general and food waste, and they must be sorted by material. Common categories include paper, cardboard, glass, metal cans, PET bottles, other plastics, vinyl/film, and styrofoam. A few habits keep you on the right side of the rules:
- Rinse and dry containers — dirty items can be rejected.
- Flatten cardboard boxes and remove tape.
- Remove caps and labels from PET bottles where required, and crush them.
- Keep clear PET bottles separate where your area asks for it.
Apartments usually have set days and a designated sorting area; houses and villas may follow a neighborhood schedule. Watch what your neighbors do and follow the posted notices.
Quick reference table
| Type of waste | How to dispose |
|---|---|
| General trash | Official district volume-rate bag (종량제 봉투) |
| Food waste | Food-waste bag / RFID bin / sticker, depending on building |
| Recyclables (paper, plastic, glass, cans, PET, film, styrofoam) | Sorted by material, clean and dry, on the scheduled day |
| Large items (furniture, appliances) | Paid disposal sticker / declaration to the district |
Getting rid of large items
Bulky waste — furniture, mattresses, large appliances — cannot just be set out on the street. You must declare it and pay a disposal fee, then attach the sticker or confirmation you receive. You typically arrange this through your district office (gu) or its website or app. The item is then collected on a scheduled day. Dumping a sofa on the curb without doing this is exactly the kind of illegal disposal that draws a fine.
Avoiding fines
Illegal dumping, using the wrong bags, mixing food waste into general trash, or putting recyclables out incorrectly can all lead to penalties. The most common newcomer mistakes are using a non-official bag, using a bag from the wrong district, and not separating food waste. When in doubt, ask your building manager or landlord — and if you have just moved in, our moving-in checklist covers other setup tasks too.
Where to get the rules for your area
Because everything from bag colors to collection days is set at the district level, your single best source is your own gu office. Your building manager, landlord, or apartment notice board will also tell you the local schedule and collection points. While you are sorting out home logistics, it is worth reading up on Korean utility bills so the rest of your monthly costs make sense, and keeping our emergency numbers guide on hand.
