One of the biggest surprises for visitors and new residents in Korea is the recycling system. At first glance, it can feel extremely complicated—multiple bins, specific bags, and very strict rules.

In Korea, trash is divided into categories such as general waste, food waste, plastics, paper, cans, glass, and sometimes vinyl. Each type must be separated correctly, or it may not be collected at all. Food waste, in particular, has its own rules and is never mixed with regular trash.

Most neighborhoods require residents to use designated trash bags for general waste, which are purchased at convenience stores or supermarkets. Recycling items are usually disposed of separately, often without bags.

Why is it so strict? Korea has limited landfill space and a strong focus on waste reduction. The system encourages people to think before throwing things away and to reduce unnecessary waste.

At first, many foreigners feel stressed about making mistakes. But over time, the logic becomes clear. Signs are detailed, neighbors are helpful, and once you form the habit, it becomes automatic.

What seems complicated is actually a reflection of how seriously Korea treats environmental responsibility. Once you get used to it, separating trash becomes just another normal part of daily life.
