How to Dispose of Trash in Korea: Garbage Bags, Food Waste, and Recycling Rules
If you are living in Korea for the first time, taking out the trash can be surprisingly confusing.
You cannot simply put everything into one bag and leave it outside. General waste goes into designated garbage bags, food waste is collected separately, and recyclable items need to be sorted by type.
For people who have lived in Korea for years, this is just part of everyday life. But if the system is new to you, even figuring out which bin or bag to use can take some getting used to. So how does waste sorting work in Korea, and why is trash separated this way?
Household Waste in Korea at a Glance
General Waste
Household waste that cannot be handled as food waste or recycling → designated volume-based garbage bag
Food Waste
Food scraps that can be separately collected and processed as a resource → designated food-waste disposal system
Recyclables
Items that can be recovered for recycling → separated by material
Some items, including bulky waste, discarded electronics, and batteries, require separate disposal methods.
1. How Is Household Waste Sorted in Korea?
For everyday household waste, it is easiest to start with three main categories: general waste, food waste, and recyclables.
But an item's original purpose or material does not always determine where it belongs. Something left over from a meal is not automatically food waste, and something made of paper or plastic is not automatically recyclable.
A more useful way to understand the Korean system is to think about what can happen to an item after it is thrown away. Can it be recycled? Can it be processed as food waste? Or does it need to be disposed of as general waste?
Once you understand that basic idea, Korea's rules for food waste and recycling become much easier to follow.
2. Why Does Korea Use Special Garbage Bags?
In Korea, general household waste usually has to be placed in an official volume-based waste bag, known in Korean as a jongnyangje bongtu. These bags are sold at places such as supermarkets and convenience stores.
Today, buying a garbage bag may seem like an ordinary part of life in Korea. But Koreans did not always pay for general waste according to how much they threw away.

Less General Waste and More Incentive to Separate Recyclables
The idea is straightforward: the more general waste you produce, the more official garbage bags you need to buy. Separating recyclable materials, on the other hand, reduces the amount that goes into those bags.
When the system was first introduced, people's reactions were very different from what they are today.
I still remember hearing about the new garbage bags on the news. Until then, most people had never really thought about paying to throw away household trash, so the idea came as a surprise. Some people complained, and there were even stories about people secretly dumping their garbage to avoid paying.
I also remember seeing people trying to squeeze as much trash as possible into a single bag. Sometimes the garbage would rise well above the top of the bag, with another piece of plastic pulled over it and taped down to keep everything together. It looks a little funny in hindsight, but it was also part of the process of adjusting to a completely new system.
More than 30 years later, the system feels completely ordinary. When I go grocery shopping, buying the garbage bags I need is simply another household purchase. I rarely stop to think of it as paying a waste-disposal fee.
The bags come in different sizes, and the bags you use can vary by municipality. Using the proper bag and following local disposal rules is important, as improper disposal can result in a fine.
3. How Do You Sort Food Waste in Korea?
One of the most confusing parts of trash disposal in Korea is food waste. Not everything left over from cooking or eating belongs in the food-waste bin.
Collected food waste can be processed into resources such as animal feed or compost, so items that are unsuitable for that process are excluded. One useful way to think about the distinction is to ask whether something could be used as animal feed.
| Usually Food Waste | Usually General Waste |
|---|---|
| Leftover rice | Eggshells |
| Common vegetable scraps | Clam and shellfish shells |
| Fruit flesh | Large, hard fruit pits |
| Ordinary food scraps | Hard animal bones |
A Simple Way I Remember It
When I am unsure at home, I often ask myself, “Could an animal eat this?” It is not a perfect rule for every single item, but it is an easy way to remember that something does not automatically count as food waste just because it came from food.
How food waste is collected also varies. Some areas use designated food-waste bags, while many apartment complexes have separate collection bins or machines that measure how much food waste each household throws away. For exact sorting and disposal rules, it is best to check the guidelines where you live.
Personally, taking out food waste is still one of my least favorite household chores. If I get into the elevator carrying a bag of food waste and a neighbor gets in halfway down, I sometimes feel a little apologetic because of the smell. It is one of those very ordinary moments that comes with apartment living in Korea.
4. How Do You Separate Recycling in Korea?
Paper, plastic, cans, glass bottles, plastic film, and other recyclable materials are generally separated from regular household waste in Korea.
But material alone is not the only thing that matters. A recyclable item may be difficult to process if it still contains food or other residue, so the condition of the item when you throw it away matters too.
Three Things to Do Before Recycling
1. Empty It
Remove anything left inside the container.
2. Clean It
Remove food and other residue as much as reasonably possible.
3. Separate It
When possible, separate different materials and place them in the appropriate recycling category.
In Korea, bottled water without plastic labels has also become increasingly common as a way to make recycling easier. The bottled water we drink at home comes in label-free bottles, so there is no plastic label to peel off before recycling the empty bottle.
At apartment recycling areas, it is common to see separate collection spaces for paper, plastic, cans, glass, and other materials.
When I lived in an apartment, I would often run into neighbors at the recycling area the night before collection day. Everyone would come down carrying the cardboard boxes, plastic bottles, and cans they had accumulated at home and sort them into the appropriate places.
Sometimes, watching my neighbors carefully sort their recycling made me feel unexpectedly hopeful. No one was standing there making them do it, yet so many people were willing to put in that small amount of effort. Moments like that made me think that perhaps the world my children will grow up in might not be such a bad one after all.
5. When and Where Do You Take Out Trash in Korea?
Where and when you take out your trash depends on both your municipality and the type of housing you live in.
When I lived in an apartment, I had to carry recyclables and food waste downstairs in the elevator to a shared collection area. Large apartment complexes often have several recycling stations, so they are not necessarily far away, but carrying everything from your home to the collection area can still be a small chore.
I now live in a detached house. Where I live, I sort the waste and put it outside my home according to the local collection rules. Compared with apartment living, I find it convenient not to have to carry bags of waste through the building and down to a recycling area.
That does not mean every apartment or detached house in Korea follows exactly the same system. Collection days and times, food-waste systems, designated bags, and recycling locations can all vary depending on the municipality and the building.
If You Are New to Korea, Check These First
- Which designated garbage bags are used in your area
- The collection days and times for general waste and recyclables
- How food waste is collected where you live
- Any additional rules for your apartment building or neighborhood
If you are actually living in Korea, local instructions are more reliable than assuming that a general rule you found online applies everywhere.
A Routine That Now Feels Completely Normal
Tonight, after dinner, I will probably do what I usually do: separate the leftover food and inedible scraps, check which packaging can be recycled, and put everything where it belongs. When the general-waste bag is full, I will tie it up and put it out according to the collection rules.
I do not do these things every evening while consciously thinking that I am doing something special for the environment. After years of repetition, they simply feel like ordinary household habits.
More than 30 years ago, even the idea of paying to throw away trash felt unfamiliar to many Koreans. Today, sorting before throwing away has become an ordinary part of everyday life in Korea.
If all the bags, bins, and recycling categories seem confusing at first, start with two things: figure out what kind of waste you have, and check the disposal rules where you live. Once you know those, Korea's trash system becomes much easier to navigate.
