쓰레기 (Trash) refers to waste materials that are discarded because they are no longer useful or needed. This can include items like food scraps, packaging, and broken objects. Proper disposal of trash is important to maintain a clean environment and prevent pollution. There are various methods for managing 쓰레기, such as recycling, composting, and landfilling. Recycling helps to recover valuable materials, while composting turns organic waste into nutrient-rich soil. Landfills are designated areas where trash is buried, but they can pose environmental challenges if not managed properly.
