Trash cans are containers used to hold waste and garbage until it can be disposed of properly. They come in various sizes and materials, such as plastic or metal, and are often found in homes, offices, and public spaces. Using a trash can helps keep areas clean and organized, making it easier to manage waste. Many trash cans have lids to prevent odors and keep pests away. Some are designed for recycling, allowing people to separate items like paper, plastic, and glass. This helps reduce waste and promotes environmental sustainability, making it easier for communities to manage their recycling programs.
