How Recycling Works in Korea: A Complete Guide for Foreigners
How Recycling Works in Korea: A Complete Guide for Foreigners
If you are living in Korea for the first time, one of the everyday systems you will need to learn is recycling and waste separation.
Korea has a detailed waste-disposal system. Instead of putting most household waste into one garbage bin, residents separate recyclable materials, food waste and general waste.
For foreigners, this can seem confusing at first.
Should a plastic bottle go into the plastic recycling bin?
What about a coffee cup?
Are food scraps always considered food waste?
Where should you throw away cardboard boxes?
And what exactly is a standard garbage bag, or 종량제봉투?
Once you understand the basic rules, however, recycling in Korea is quite straightforward.
This guide explains how recycling works in Korea, what goes into each category, how to dispose of food waste, where to buy official garbage bags and what foreigners should know before throwing something away.
1. Why Is Waste Separated in Korea?
Korea uses a system in which different types of household waste are collected separately.
The basic categories include:
General waste
Recyclable materials
Food waste
Large waste
Special waste such as batteries and fluorescent lamps
In Seoul, official guidance states that general waste should be placed in designated standard garbage bags, while recyclable materials and food waste are handled separately.
The goal is to reduce the amount of waste that needs to be incinerated or landfilled and to recover useful materials.
For foreigners, the most important thing to remember is:
Not everything that looks recyclable actually belongs in the recycling bin.
The material, cleanliness and local collection rules all matter.
2. The Basic Rule: Empty, Rinse, Separate
One of the easiest ways to remember Korean recycling rules is:
Empty it.
Rinse it.
Separate it.
Before recycling a container, remove the contents.
If necessary, rinse the container.
Then separate it according to its material.
Seoul's recycling guidance emphasizes emptying containers, removing contaminants and separating materials appropriately.
For example, if you finish a bottle of juice:
Empty the remaining drink.
Rinse the bottle if necessary.
Separate materials such as the label or cap when required.
Put the bottle in the appropriate recycling collection area.
This simple routine will help you avoid most common mistakes.
3. General Waste: 종량제봉투
General household waste is usually placed in a 종량제봉투, often translated as a standard-volume garbage bag or pay-as-you-throw garbage bag.
These bags are officially designated for general waste.
You can commonly purchase them at places such as supermarkets and convenience stores, although availability and bag types can vary by area.
The important point is that you should not normally use an ordinary plastic shopping bag for household general waste when your local area requires a designated 종량제봉투.
The cost of the bag is effectively part of the waste-disposal system.
The more general waste you produce, the more designated bags you need.
4. What Goes Into General Waste?
General waste includes items that cannot be recycled under the applicable local rules.
Examples can include:
Used tissues
Contaminated paper
Some heavily contaminated packaging
Certain composite materials
Items that are not accepted as recyclable materials
However, the exact list can vary.
One important point is that something being made of paper or plastic does not automatically mean it is recyclable.
For example, heavily contaminated or composite materials may need to go into general waste instead.
Seoul's current guidance lists items such as receipts, certain coated paper products and used tissues among materials that should not be placed with ordinary paper recycling.
5. How to Recycle Plastic
Plastic containers are among the most common recyclable materials in Korea.
Before recycling plastic:
Empty the container.
Rinse it.
Remove unnecessary foreign materials.
Separate it according to the local collection system.
Common recyclable plastic items include many plastic containers and bottles bearing recognized recycling symbols.
However, not every plastic-looking object belongs in the plastic recycling bin.
Items such as certain toys, pens and mixed-material products may be excluded depending on the local standard.
This is why checking the recycling symbol and local disposal guide is important.
6. How to Recycle PET Bottles
PET drink bottles are especially important in Korea.
For a typical plastic drink bottle:
Empty the bottle.
Rinse it if necessary.
Remove the label when required.
Separate the cap if required by the local system.
Compress the bottle where appropriate.
Put it in the designated collection area.
In Seoul, transparent PET bottles are managed separately from other plastic bottles in applicable collection systems.
If you live in an apartment, look at the signs in the recycling area.
The collection bins may have separate sections for transparent PET bottles and other plastics.
7. What About Plastic Bags and Wrappers?
This is one of the most confusing categories for foreigners.
Some plastic bags and flexible packaging can be recycled as vinyl, or 비닐류, rather than ordinary plastic.
Examples can include:
Snack bags
Instant noodle packages
Plastic shopping bags
Some food packaging
The material should be reasonably clean and free of leftover food.
Seoul's current vinyl recycling guidance says plastic bags should be collected separately, and that food contents should be removed. It also states that solid contamination such as sauce should be rinsed off when possible.
If contamination cannot reasonably be removed, the item may need to go into general waste depending on the applicable local rules.
8. How to Recycle Paper and Cardboard
Paper and cardboard are common recyclable materials.
Examples include:
Newspapers
Books
Notebooks
Cardboard boxes
Paper bags
Clean paper packaging
Before recycling cardboard:
Remove tape.
Remove plastic or other materials.
Keep the paper dry.
Flatten boxes when possible.
Seoul's guidance specifically recommends removing tape from ordinary cardboard boxes before placing them with paper recycling.
A wet or heavily contaminated cardboard box may not be suitable for normal paper recycling.
9. What About Receipts?
Receipts are a common source of confusion.
You might think:
“It's paper, so it should be recycled.”
Not necessarily.
Thermal paper receipts are generally not treated as ordinary recyclable paper in Seoul's current guidance.
The same applies to certain coated or composite paper products.
Seoul currently lists receipts and some coated paper products as materials that should go into general waste rather than ordinary paper recycling.
So don't automatically put every piece of paper into the paper recycling bin.
10. How to Recycle Glass Bottles
Glass bottles such as beverage bottles can generally be recycled when they meet the applicable collection criteria.
Before disposal:
Empty the bottle.
Rinse it.
Remove the cap where required.
Put it in the glass collection area.
Typical recyclable glass can include beverage bottles.
However, not all glass is recyclable as glass bottles.
Items such as:
Mirrors
Window glass
Certain heat-resistant glass
Ceramics
Porcelain
may belong in other waste categories.
Seoul's current guidance specifically distinguishes ordinary beverage glass bottles from materials such as broken glass, heat-resistant glass, crystal and ceramics.
11. What Should You Do With Broken Glass?
Broken glass requires special care.
Do not simply place broken glass loose inside a recycling bin.
Seoul's guidance says small quantities of broken glass should be wrapped in newspaper and placed in the appropriate general-waste bag, while larger quantities may require a special-purpose disposal bag or other designated method.
The exact procedure can vary depending on the local authority.
The most important rule is:
Protect yourself and waste-collection workers from sharp glass.
12. How Does Food Waste Work in Korea?
Food waste is handled separately from ordinary household waste in many Korean residential areas.
You may see:
Food waste collection bins
or designated food-waste bags.
Seoul's official foreign-resident information states that food waste is disposed of through designated bags or food-waste collection containers, but the specific system can vary depending on the district and housing type.
This is particularly important for foreigners living in apartments.
Your apartment complex may have a dedicated food-waste machine or collection area.
Follow the instructions posted there.
13. What Is NOT Food Waste?
This is one of the most important things to understand.
Not everything that comes from food belongs in the food-waste bin.
Examples that can be classified as general waste under Seoul guidance include:
Fish bones
Meat bones
Eggshells
Onion skins
Vegetable roots
Hard fruit shells
Certain hard seeds
Shellfish shells
Seoul specifically identifies items such as fish bones, animal bones, eggshells, onion skins and hard fruit shells as general waste rather than food waste.
This is a common mistake among people who are unfamiliar with the Korean system.
A useful rule is:
If it is extremely hard, fibrous or difficult to process, check before putting it into food waste.
14. Food Waste Should Not Contain Excess Liquid
When disposing of food waste, remove as much unnecessary liquid as possible.
For example, if you have leftover soup, do not simply pour the entire container into a food-waste collection bin.
Separate the liquid according to local disposal rules and place the solid food waste into the designated container.
Reducing excess moisture also helps keep the collection area cleaner.
15. What About Coffee Grounds?
Coffee grounds are another item that can confuse foreigners.
Do not automatically assume that anything organic belongs in the food-waste bin.
Local guidance can differ for specific materials.
If you regularly drink coffee at home, check your local district's disposal instructions or the official 내손안의 분리배출 app.
Seoul currently recommends using the app's item-specific recycling information and FAQ when residents are unsure how to dispose of an item.
16. How to Recycle Metal Cans
Metal cans are generally recyclable.
Examples include:
Aluminum drink cans
Steel cans
Certain food cans
Before recycling:
Empty the contents.
Rinse if necessary.
Separate other materials when required.
Seoul's guidance includes iron and aluminum cans among recyclable metal materials when they meet the applicable criteria.
17. What About Aerosol and Gas Canisters?
Aerosol cans and gas canisters require extra caution.
Do not put a can containing dangerous residual gas into a recycling bin without following the appropriate disposal procedure.
Seoul's current guidance instructs residents to remove gas from butane-type canisters in a well-ventilated location before disposal and warns about containers that still contain hazardous contents.
If you are unsure, check your district's official disposal instructions.
Safety is more important than simply recycling an item quickly.
18. Batteries Have Their Own Collection System
Do not throw used batteries into ordinary household waste if a designated battery collection point is available.
You can often find battery collection boxes in places such as:
Apartment complexes
Community service centers
Schools
Subway stations
Seoul's foreign-resident living guide specifically notes that batteries should be placed in designated battery-disposal boxes.
This is important because batteries can create safety problems when mixed with ordinary waste.
19. What About Clothes?
Old clothes should generally not simply be thrown into ordinary recycling bins.
Many residential neighborhoods have dedicated clothing collection boxes.
You may see:
의류수거함
which means:
clothing collection box.
If the item is unsuitable for donation or textile recycling, the disposal method may be different.
Check the instructions on the collection box or your local district's guidance.
20. How to Dispose of Large Items
Large household items are handled differently from normal household waste.
Examples include:
Furniture
Large appliances
Mattresses
Large household equipment
You generally need to report large waste and pay the applicable fee before putting the item out.
Seoul's official foreign-resident information says large waste such as furniture and appliances requires a large-waste report, which can be handled through the district office website or local community service center.
Do not simply leave a sofa or large appliance next to a normal recycling area.
21. What About Electronics?
Small electronics may have designated collection systems depending on the item and location.
Large appliances may qualify for free pickup services under applicable programs.
Seoul's recycling guidance distinguishes large and small appliances and provides different disposal methods.
If you are throwing away an electronic device, check your local district's instructions before putting it into a general recycling bin.
22. Recycling in an Apartment
Apartment complexes in Korea often make recycling relatively easy.
You may have a dedicated recycling area with separate sections for:
Paper
Plastic
PET bottles
Glass
Metal
Vinyl
Food waste
General waste
There may also be specific collection days.
Follow the signs posted at your apartment.
This is important because the collection schedule and exact procedures can differ between buildings.
23. What About a One-Room Apartment?
If you live in a studio or one-room apartment, your building may have a smaller waste-disposal area.
You may need to use:
Designated general-waste bags
Food-waste containers
Recycling collection points
Community collection areas
The landlord or building manager can usually explain the local system.
A useful Korean question is:
“쓰레기는 어디에 버려요?”
It means:
“Where should I throw away the garbage?”
Another useful question is:
“재활용은 어디에 버려요?”
which means:
“Where should I put recyclables?”
24. Recycling Rules Can Differ by City
This is extremely important for foreigners.
Korea does not have one single identical disposal procedure for every household and every city.
Local governments and housing types can have different collection arrangements.
Seoul's official information specifically notes that food-waste disposal can differ by district and residential type. The city also advises residents to confirm recycling collection rules with their local district office.
Therefore, this article should be used as a general guide.
If the sign at your apartment says something different, follow the local instructions.
25. How to Check the Correct Disposal Method
If you are unsure about an item, don't guess.
Seoul recommends the 내손안의 분리배출 app, which provides item-specific disposal information, FAQs and a Q&A function.
You can also search your local district office website.
Useful Korean search terms include:
분리배출
meaning recycling separation/disposal
쓰레기 배출
meaning waste disposal
음식물쓰레기
meaning food waste
종량제봉투
meaning standard garbage bag
