A trash bin is a container used for collecting waste materials, such as food scraps, paper, and other discarded items. It is commonly found in homes, offices, and public spaces to promote cleanliness and proper waste disposal. Trash bins come in various sizes and designs, often made from materials like plastic or metal. Most trash bins have a lid to contain odors and prevent pests from accessing the waste. Some bins are specifically designed for recycling, separating materials like glass, plastic, and paper to support environmental sustainability. Proper use of a trash bin helps reduce litter and maintain a tidy environment.
