In Korea, separate household waste into general trash, food waste, recyclables, and oversized items. General trash must go in your local paid volume-based bag, food waste uses a separate bag or apartment RFID bin, and clean recyclables are usually sorted without a paid trash bag. Rules vary by district and building, so check the notice board in your apartment, officetel, guesthouse, or local district office before your first trash day.
Korea's trash system is easy once someone shows you the pattern, but it is confusing on day one because the rules are local and the wrong bag can get rejected. The big idea is simple: you pay for what cannot be recycled, and you separate the rest.
If you are staying in a hotel, follow the hotel bins. If you are living in an apartment, officetel, goshiwon, share house, or Airbnb, ask for the building's disposal days and sorting rules before you pile bags near the elevator.
What are the main trash categories in Korea?
Most households should think in four buckets:
Category | Where it goes | Common examples |
|---|---|---|
General trash | Local paid trash bag | Tissues, contaminated packaging, small non-recyclable waste |
Food waste | Food waste bag or RFID food bin | Vegetable scraps, rice, leftovers that your building accepts |
Recyclables | Building or street recycling area | Clean paper, plastic bottles, cans, glass, cardboard |
Oversized items | Prepaid sticker or district pickup | Furniture, mattresses, large appliances, big shelves |
Do not treat "trash" as one bag. A normal Korean building may reject a bag if it has food waste, recyclables, or the wrong district bag inside.
Where do you buy Korean garbage bags?
Buy local volume-based garbage bags at convenience stores, supermarkets, marts, or neighborhood shops near your home. Ask for jongnyangje bongtu if you need the paid general trash bag.
The most important rule is that the bag must match your local area. A paid bag bought in one district or city may not be accepted in another. If you moved from Mapo to Gangnam, for example, do not assume your old bags still work.
For short stays, buy the smallest useful size first. You may see sizes such as 5L, 10L, and 20L, but availability and prices vary by district. A solo resident should usually start small because Korean food waste and recycling are separated out of the general trash bag.
How does food waste work in Korea?
Food waste is handled separately from general trash. Depending on your building and district, you may use a small food waste bag, a shared food waste bin, or an RFID food waste machine that charges by weight.
In Seoul apartments with RFID food waste bins, the fee can be charged through the building or maintenance bill instead of through a physical bag. Recent reporting on Seoul's RFID system described an example rate of about ₩130 per kilogram, but your building's actual billing method can be different.
The practical rule is: drain liquid before disposal. Wet food waste smells worse, weighs more, and can be rejected if it includes things your local processor does not accept.
Common food-waste mistakes include putting in:
- Plastic wrap, stickers, toothpicks, or rubber bands
- Shells, hard bones, and large pits if your local rules exclude them
- Liquids, oil, soup, or sauce in large amounts
- Disposable containers with food still inside
When in doubt, check your building's posted list. Food waste rules can be surprisingly specific.
How should you sort recyclables?
Recycling in Korea works best when items are clean, empty, and separated by material. Rinse bottles and cans, flatten cardboard, remove leftover food, and do not hide general trash inside recycling.
Common recycling groups are:
1. Paper and cardboard — boxes, clean paper, paper packaging.
2. Plastic bottles and containers — emptied and rinsed.
3. Cans and metal — drink cans, food cans, clean metal items.
4. Glass bottles — bottles and jars, separated from broken glass where required.
5. Vinyl and plastic film — only where your building or district collects it separately.
Apartment buildings often have labeled recycling areas and specific collection days. Villas and small buildings may use street-side pickup rules, which can be stricter about time and location.
What do you do with furniture or large items?
Do not leave furniture, mattresses, fans, chairs, suitcases, or large appliances in the recycling area without checking the pickup process. Oversized waste usually needs a prepaid sticker, online reservation, or district pickup request.
The process depends on the district, but the usual flow is:
1. Apply through the local district office website or app, or buy the required sticker where available.
2. Pay the disposal fee for the item type.
3. Attach the sticker or write the pickup information clearly.
4. Put the item out only at the approved place and time.
If you are leaving Korea, plan this before moving week. Large-item pickup is not always same-day, and landlords may charge you if abandoned furniture causes a building complaint.
What mistakes can lead to fines or rejected trash?
The most common problems are not dramatic. They are small sorting errors repeated often.
Avoid these:
- Using a paid bag from the wrong district
- Putting food waste inside general trash
- Throwing clean recyclables into the paid trash bag
- Leaving trash outside the allowed time window
- Putting bulky items out without a sticker or reservation
- Mixing batteries, electronics, glass shards, or hazardous items into normal trash
If you are new to the building, take a photo of the disposal notice and translate it. The posted rules at your actual building matter more than generic advice online.

Frequently asked questions
Can I use any Korean trash bag anywhere?
No. Paid trash bags are local, so a bag from one district or city may not be accepted somewhere else. Buy bags near the place where you will throw them away.
Are recyclables free to throw away in Korea?
Clean recyclables are usually separated without using a paid general trash bag. They still must be sorted by your building or district rules, and dirty packaging may be treated as general trash.
What happens if I put food waste in general trash?
Your bag may be rejected, your building may complain, or you may be fined depending on local enforcement. Separate food waste into the required bag, bin, or RFID machine.
How do I throw away a mattress or chair in Korea?
Large items usually need a district pickup request, prepaid sticker, or disposal fee. Check your local district office or building manager before putting the item outside.
What should Airbnb guests do with trash in Korea?
Ask the host for the exact trash days, bag type, and recycling location. Do not leave mixed trash in a hallway or public bin unless the host has given that specific instruction.
