Waste bins are containers designed to hold trash and recyclable materials. They come in various sizes and shapes, making them suitable for different environments, such as homes, offices, and public spaces. Waste bins help keep areas clean and organized by providing a designated place for waste disposal. Many waste bins are color-coded to encourage proper sorting of materials. For example, recycling bins are often blue or green, while general waste bins may be black or gray. This system helps promote recycling and reduces the amount of waste sent to landfills, contributing to a cleaner environment.
